-\b;Arrays
-An array is basically a collection of variables of the same type or class. You can use N dimensionnal arrays in the CBOT language. Each dimension is limited to 9999 elements. You must use square brackets \c;[]\n; after the type name or the variable name to declare an array.
-\c;

-\s;int    a [12];  // an array of int limited to 12 elements

-\n;
-As soon as you put values into the array, the elements are created and the reference is initialized:

-\s;a[2] = 213;  // a points to
-\s;             // 3 élements [0], [1] et [2]
-\n;
-After this operation, \c;a\n; contains a reference to the elements of the array. Elements \c;[0]\n; and \c;[1]\n; are created but not initialized because an array cannot contain empty elements.

-\b;Blocks
-You can use braces \c;{ }\n; to group a number of instructions together in order to make one single block out of them, for example: 
-\c;
-\s;	{
-\s;		float  t;
-\s;		t = a;
-\s;		a = b;
-\s;		b = t;  // switches round a and b
-\s;	}
-\n;
-Every instruction in the block is followed by a \l;semicolon\u cbot\term;, but the block itself is not. 
-Let us take the following example with the instruction \c;\l;if\u cbot\if;\n; to illustrate the use of blocks in a program:
-\c;
-\s;	if ( a < b )
-\s;		\n;instruction 1\c;;
-\s;		\n;instruction 2\c;;
-\s;	\n;instruction 3\c;;
-\n;
-If the \l;condition\u cbot\cond; is true, instructions 1, 2 and 3 are performed. If the condition is false, only instruction 1 is ignored, instructions 2 and 3 are performed. The fact that instruction 2 is lined up with instruction 1 does not matter. 
-If you want to perform instructions 1 and 2 only if the condition is true, you have to bracket them together in a block: 
-\c;
-\s;	if ( a < b )
-\s;	{
-\s;		\n;instruction 1\c;;
-\s;		\n;instruction 2\c;;
-\s;	}
-\s;	\n;instruction 3\c;;
-\n;
-Blocks may be needed with instructions \c;\l;if\u cbot\if;\n;, \c;\l;while\u cbot\while;\n; and \c;\l;for\u cbot\for;\n;, in order to group several instructions that should be performed only if a condition is true, or repeated several times. 
-You can fit blocks into other blocks, on as many levels as you need. Here is an example of imbrication on two levels :
-\c;
-\s;	if ( a > b )
-\s;	{
-\s;		int  i = 0;
-\s;		while ( i < 18 )
-\s;		{
-\s;			move(10);
-\s;			turn(5);
-\s;			i = i+1;
-\s;		}

-You had better line up the open brace \c;{\n; with the closing brace \c;}\n; in order to improve readability, but it is not compulsory. The following example takes less space, is equivalent to the previous example, but it is not advisable to write your programs in the following style : 
-\c;
-\s;	if(a>b) { int i=0; while(i<18) {
-\s;	move(10);turn(5);i=i+1; }}

+\b;Blocks
+You can use braces \c;{ }\n; to group a number of instructions together in order to make one single block out of them, for example: 
+\c;
+\s;	{
+\s;		float  t;
+\s;		t = a;
+\s;		a = b;
+\s;		b = t;  // switches round a and b
+\s;	}
+\n;
+Every instruction in the block is followed by a \l;semicolon\u cbot\term;, but the block itself is not. 
+Let us take the following example with the instruction \c;\l;if\u cbot\if;\n; to illustrate the use of blocks in a program:
+\c;
+\s;	if ( a < b )
+\s;		\n;instruction 1\c;;
+\s;		\n;instruction 2\c;;
+\s;	\n;instruction 3\c;;
+\n;
+If the \l;condition\u cbot\cond; is true, instructions 1, 2 and 3 are performed. If the condition is false, only instruction 1 is ignored, instructions 2 and 3 are performed. The fact that instruction 2 is lined up with instruction 1 does not matter. 
+If you want to perform instructions 1 and 2 only if the condition is true, you have to bracket them together in a block: 
+\c;
+\s;	if ( a < b )
+\s;	{
+\s;		\n;instruction 1\c;;
+\s;		\n;instruction 2\c;;
+\s;	}
+\s;	\n;instruction 3\c;;
+\n;
+Blocks may be needed with instructions \c;\l;if\u cbot\if;\n;, \c;\l;while\u cbot\while;\n; and \c;\l;for\u cbot\for;\n;, in order to group several instructions that should be performed only if a condition is true, or repeated several times. 
+You can fit blocks into other blocks, on as many levels as you need. Here is an example of imbrication on two levels :
+\c;
+\s;	if ( a > b )
+\s;	{
+\s;		int  i = 0;
+\s;		while ( i < 18 )
+\s;		{
+\s;			move(10);
+\s;			turn(5);
+\s;			i = i+1;
+\s;		}
+\s;	}

-Classes can only be \l;public\u cbot\public;, that is they can be used from all bots in a mission. Class members are also public, that is they are accessible from outside the class. Class members can be fields or functions (also called methods), for example the followin class \c;MyClass\n; contains 4 fields (a, b, x and s) and one method (MyFunction).

+Classes can only be \l;public\u cbot\public;, that is they can be used from all bots in a mission. Class members are also public, that is they are accessible from outside the class. Class members can be fields or functions (also called methods), for example the followin class \c;MyClass\n; contains 4 fields (a, b, x and s) and one method (MyFunction).

-\b;Instruction \c;drop\n;
-The instruction \c;drop();\n; instructs the bot to drop whatever the operating arm is carrying on the ground, on the platform of a building or on the power cell location of a bot.

-
-\t;oper: \c;\l;int\u cbot\int;\n; (default value\c;InFront\n;)

-The value of the expression \c;a++\n; is the value of the variable \c;a\n; before the increment. If you use the prefix operator \c;++a\n; the value of the expression is the value of the variable \c;a\n; after the increment. The same holds for the \c;--\n; decrement operator.

+\b;Instruction \c;grab\n;
+The instruction \c;grab();\n; instructs the bot to use the operating arm to grab an object located on the ground, on the platform of a building or on the power cell location of a bot.
+
+\b;Basic use
+The instruction \c;grab();\n; written in this form grabs the object located in front of the bot. Here is a short program that grabs an object in front of the bot and drops it 5 meters further:
+\c;
+\s;	grab();
+\s;	\l;move\u cbot\move;(5);
+\s;	\l;drop\u cbot\drop;();
+\n;
+\b;For specialists
+Syntax:
+\s;\c;grab ( oper );\n;
+
+This instruction appeals to the operating arm of a \l;grabber bot\u object\botgr;, in order to grab the closest object.
+
+\t;oper: \c;\l;int\u cbot\int;\n; (default value\c;InFront\n;)
+Oper indicates where the bot should look for an object to grab. If no indication is given, the object is picked up in front of the bot.
+\c;InFront   \n;  Grabs in front (default value).
+\c;Behind    \n;  Grabs behind.
+\c;EnergyCell\n;  Grabs the bot's own power cell.
+
+\t;Return value: \c;\l;int\u cbot\int;\n;
+Normally an error stops the program. You can prevent the program from stopping on errors by using the \c;\l;errmode\u cbot\errmode;(0)\n; instruction. A value different from zero if an error occurred is then returned by \c;grab();\n;.
+\c;== 0 \n;an object was grabbed
+\c;!= 0 \n;error, no object was grabbed

-
-\s;\c;category\n;
-The \n;\l;category\u cbot\category; of an object allows you to know what it is, f. ex. what kind of bot, building, enemy, etc. 
-
-\s;\c;position\n;
-Position of the object on the planet, in meters. The coordinates \c;x\n; and \c;y\n; correspond to the location on a map, the \c;z\n; coordinate corresponds to the altitude above (respectively below) sea level. 
-
-\s;\c;orientation\n;
-Orientation of the object, in degrees. The orientation tells you what direction the object is facing. An orientation of \c;0\n; corresponds to an object facing eastwards, thus following the positive \c;x\n; axis. The orientation is measured counterclockwise. 
-
-\s;\c;pitch\n;
-Forward/backward angle of the robot. A pitch of \c;0\n; means that the bot is standing on flat ground. A positive inclination means that it is facing upwards, a negative inclination means that it is facing downwards. 
-
-\s;\c;roll\n;
-Left/right angle of the bot, in degrees. A positive value means that the bot is leaning to the left side, a negative value means that it is leaning to the right side. 
-
-\s;\c;energyLevel\n;
-Energy level, between 0 and 1. A normal \l;power cell\u object\power; that is fully charged returns the value \c;1\n;. A \l;nuclear power cell\u object\atomic; never returns a value higher than 1, it just lasts longer. Attention: The energy level of a bot is always zero, because the energy is not contained in the bot, but in the power cell. To know the energy level of the power cell of a bot, you must write \c;energyCell.energyLevel\n;. 
-
-\s;\c;shieldLevel\n;
-Shield level of a robot or building. A level \c;1\n; indicates that the shield is still perfect. Every time that the bot or building gets a bullet or collides with another object, the shield level decreases. When the level reaches \c;0\n;, the next bullet or collision will destroy the bot or building. 
-Bots can re-energize their shield on a \l;repair center\u object\repair;. The shield of a building is repaired if it lays inside the protection sphere of a \l;shielder\u object\botshld;.
-
-\s;\c;temperature\n;
-Temperature of the jet of \l;winged bots\u object\botgj;. \c;0\n; corresponds to a cold jet. When used, the temperature increases progressively. When it reaches the value \c;1\n;, the jet is overheated and stops working, until it cooled down a little. 
-
-\s;\c;altitude\n;
-The \c;z\n; coordinate of the position indicates the altitude above sea level, whereas the \c;altitude\n; indicates the height above ground. This value is meaningful only for \l;winged bots\u object\botgj; and for \l;wasps\u object\wasp;. For all other objects, this value is zero. 
-
-\s;\c;lifeTime\n;
-The age of the object in seconds since it's creation.
-
-\s;\c;energyCell\n;
-This information is special, because it returns the information about another object, in this case the power pack. This means that energyCell contains all the characteristics of a normal object, for example \c;category\n; (PowerCell or NuclearCell), \c;position\n; (the position of the cell), etc.
-If you want to know the energy level of a robot, you must not check \c;energyLevel\n;, but \c;energyCell.energyLevel\n;.
-If the bot has bot no power cell, \c;energyCell\n; returns \c;null\n;.
-
-\s;\c;load\n;
-This information also returns the description of a whole object: the description of the object carried by a \l;grabber\u object\botgr;. If it carries nothing, \c;load\n; returns \c;null\n;.
-
-\b;Examples
-The type \c;object\n; returns the special value \c;\l;null\u cbot\null;\n; when the object does not exist. For example:
-\c;
-\s;	object a;
-\s;	a = radar(BotGrabberRoller);
-\s;	if ( a == null )  // object does not exist ?
-\s;	{

-\b;Variables
-A variable is like a box, where you can put some information. The content of the variable can change during the execution of the program.
-
-For example, you can use a variable to count the number of titanium ore units that the grabber has collected and carried to the converter. First, you must find a name for it: the name should not be too long, but explain by itself what the variable is used for. Let's call it \c;countTit\n;. This variable must contain only whole numbers, so choose the type \c;int\n;. At the beginning of the program, you must declare the variable. Then you put the value \c;0\n; into the variable, and every time you grab a titanium ore, you increase the variable by \c;1\n;. At every moment, the variable contains the number of titanium ore units that the grabber collected.
-
-For the declaration of the variable, write the following line: 
-\c;\s;	int  countTit;\n;
-
-To put \c;0\n; into the variable, write:
-\c;\s;	countTit = 0;\n;
-
-At every titanium ore grabbed, write:
-\c;\s;	countTit = countTit + 1\n;
-
-You have much freedom in the choice of the name for a variable, you can call them by any name, f. ex.: \c;dist\n;, \c;direct\n;, \c;p2\n;, \c;a\n;, \c;x\n;, \c;nothing_2_shoot_at\n;, etc.
-A variable name must always begin with a letter. It can be followed by any combination of letters, digits or the underscore character \c;_\n;. You can of course not use the keywords of the CBOT language like \c;\l;for\u cbot\for;\n;, \c;\l;while\u cbot\while;\n;, \c;\l;break\u cbot\break;\n;, \c;\l;continue\u cbot\continue;\n;, \c;do\n;, etc.
-You should be careful about the choice of the names that you give to variables; writing a program can become very difficult if you forget the names of variables or if you do not remember what they are used for. Elaborate your own system to find variable names, and do not use names like \c;Bmo45\n;, \c;a\n; or \c;tgBinX\n;.
-
-In the example above, the keyword \c;int\n; indicates that this variable can contain only whole numbers, which is adequate to counting objects. If you want to measure a distance, better use a variable that can contain also real numbers, with a fractional part (like 3.45 or 0.034): in this case, use the type \c;float\n;.
-
-In fact, a variable is made up of three parts:
-1) the name
-2) the type of the information stored inside
-3) the content, i.e. the information itself
-
-\t;the name
-You need the name to be able to distinguish the different variables from each other.
-
-\t;the type
-The \l;type\u cbot\type; determines what kind of information the variable can contain. According to the type, a variable can contain a whole number, a real number, a string, the coordinates of a point, information about an object, etc. 
-Here is a list of the most common variable types:
-  o  \c;\l;int\u cbot\int;\n; for a whole number (12, -500, etc.)
-  o  \c;\l;float\u cbot\float;\n; for a real number (3.14, 0.2, -99.98, etc.)

-  o  \c;\l;point\u cbot\point;\n; for a x,y,z-coordinate in space
-  o  \c;\l;object\u cbot\object;\n; for information about an object (bot, building, etc.)
-
-\t;The content
-The content of a variable is an information of the kind specified in the type. It can change during the execution of the program. 
-
-Once you declared a variable, it still does not contain any value. Before you can use it, you must put a value inside: 
-\c;\s;	int  i, j;

-\s;	j = i;   // can not write this, because i has got no content yet.
-\n;
-You can also declare a variable and put a value inside in the same line, writing: 
-\c;\s;	int  countTit = 0;
-\n; 
-When you assign a value to a variable with the equals sign \c;=\n;, the value on the right side is copied into the value on the left side. Consider the following example: 
-\c;\s;	int  i, j;
-\s;	i = 5+2;  // i takes the value 7
-\s;	j = i+6;  // j takes the value of i plus 6, this is 13
-\s;	i = j;    // i takes the value of j, this is 13
-\n;
-At the end of this example, both variables \c;i\n; and \c;j\n; contain the value \c;13\n;.
-
-The following assignment is not correct, because on the left side of the equals sign \c;=\n;, there can be only a variable name:
-\c;\s;	i+2 = j;  // impossible
-\n;
-If you want to exchange the values of two variables, you must use a third variable. Here is an example to exchange the content of two variables \c;a\n; and \c;b\n; :
-\c;\s;	int temp;
-\s;	temp = a;  // temp takes the value of a
-\s;	a = b;     // the content of b is copied into a

+\b;Instruction \c;while\n;
+The instruction \c;while () {}\n; is used to repeat a set of instructions several times.
+
+\b;Basic use
+The most frequent use of \c;while\n; consists in repeating a set of instructions again and again. In order to achieve this, write \c;while (true) {}\n; and put the instructions to be repeated in braces \c;{}\n;. As an example, here is a program that repeats again and again the following actions:
+o  look for a spider,
+o  turn towards it,
+o  shoot.
+\c;
+\s;	while (true)
+\s;	{
+\s;		item = \l;radar\u cbot\radar;(AlienSpider);

+We relayed a transmission to your \l;bot factory\u object\factory;. It concerns a bot designed to detect raw materials in the subsoil: energy sources, ore. We call it a \l;sniffer\u object\botsr; for short. Preliminary analysis leads us to believe that the presence of titanium ore on Crystalium is closely linked to the growth of large blue crystals. If this is indeed the case, this information should allow you to save some precious time. A \l;derrick\u object\derrick; is of course required for the extraction.

-We are pleased to inform you that you have been selected for the space exploration mission Colobot.
-
-Your psychological profile has been established as more than 98.84% favorable, and your aptitude during the extensive testing period was undeniable. The detailed results are at your disposal in the central computer under the registration number that was assigned to you.

-\b;From Houston Mission Control
-As you know, Earth is heading towards imminent disaster, due to increasing atmospheric pollution.
-
-\l;Your\u object\human; mission consists of exploring neighboring galaxies with the hopes of finding a planet that will be suitable to human needs and possibly serve as a shelter for mankind. You will be on your own for the entire mission but your spaceship will be carrying a few bots along.
-
-Eight months ago an expedition composed entirely of robots was sent across the cosmos with the same objective. It encountered a fair share of obstacles along the way, apparently landing on planets that were unsuitable for colonization, even possibly outright hostile. Very recently all communications were terminated.
-
-The reasons for the mission's failure are unclear at this date, mainly because of recurrent transmission problems. It is our hope that you will be able to use some of the data it gathered to your advantage.
-
-\b;Immediate Objective
-The Nevada desert is already bustling with activity. Bots are setting up a space station catered to your specific needs.
-
-In order to let you familiarize with your spacesuit and equipment, we have set up a few training drills.
-
-In the first drill, you need to find your survival kit that contains all the tools necessary to brave the cold of outer space. It is easy to spot since it contains both an orange and a blue tank.

-1) Go to a \l;defense tower\u object\tower;.
-2) Wait until the \l;power cell\u object\power; is 80% empty.
-3) Grab the \l;power cell\u object\power; and recharge it on a \l;power station\u object\station;.
-4) Put it back on the \l;defense tower\u object\tower;.
-
-Build the \l;power station\u object\station; as close as possible to the tower in order to reduce the time when the tower has got no power cell. A good trick is to place a power cell on the ground in front of the tower. The wasp will attack the power cell, and if the first shoot misses or a wasp arrives when the defense tower has got no energy, only the power cell is destroyed and not the defense tower.

+We have developed a program that takes care of recharging the power cell of a \l;defense tower\u object\tower;:
+
+1) Go to a \l;defense tower\u object\tower;.
+2) Wait until the \l;power cell\u object\power; is 80% empty.
+3) Grab the \l;power cell\u object\power; and recharge it on a \l;power station\u object\station;.
+4) Put it back on the \l;defense tower\u object\tower;.
+
+Build the \l;power station\u object\station; as close as possible to the tower in order to reduce the time when the tower has got no power cell. A good trick is to place a power cell on the ground in front of the tower. The wasp will attack the power cell, and if the first shoot misses or a wasp arrives when the defense tower has got no energy, only the power cell is destroyed and not the defense tower.

-3) Use your reactor to fly past the lake before the gravi-plant on your right.

-4) When you leave the gravi-plant, keep on the left-hand side of the lake, and follow the shore until you reach a peninsula adorned with fern-like plants.
-
-5) Do some island-hopping across the larger lake. Aim for the trees in order to avoid falling into the water on the other side of the island. The last island is 50 cm under water but you can still land on it without having your head submerged. 
-
-6) The path continues to the left. A giant ant is waiting for you there, but it will not do you much harm.
-
-7) Give your reactor enough time to cool down, then fly across the small lake. Try to land as high on the right as you can, this is the best way not to fall into the second lake.

+This remark is valid for all buttons in COLOBOT.
+
+\t;Text scrolling
+If your mouse is equipped with a wheel, you can use it to scroll the text up and down. Otherwise, use the arrow keys and the scroll bar on the right-hand side of the screen.
+
+\t;Font size
+The cursor on the upper side of the screen allows you to change the font size of the text.

-\b;Objective
-As a defense against ants attacking from all sides, adapt the program \c;Spider2\n; in order to fly at a given altitude.
-
-\t;Program
-The program necessary for this task is somewhat similar to the program \c;Spider2\n; that looks for the closest ant, turns towards it and fires:
-\c;
-\s;extern void object::Spider2()
-\s;{	
-\s;	object    item;
-\s;	
-\s;	while (true)
-\s;	{
-\s;		item = radar(AlienSpider);
-\s;		turn(direction(item.position));
-\s;		fire(1);
-\s;	}
-\s;}
-\n;
-You can copy-paste it to the editor, and adapt it. Replace \c;radar(AlienSpider);\n; by \c;radar(AlienAnt);\n;, and write before the \c;while\n; loop another loop that activates the jet beneath the \l;winged shooter\u object\botfj; until the bot reaches an altitude of 20 meters.
-
-The instruction \c;\l;jet\u cbot\jet;()\n; controls the jet beneath winged bots. The number in brackets must range between \c;-1\n; and \c;1\n;.\c; jet(1);\n; moves the bot upward with maximum speed.\c; jet(-1);\n; moves the bot downward with maximum speed, and \c;jet(0);\n; stabilizes the altitude. As the bot must reach a precise altitude, move it upward slowly with \c;jet(0.2);\n;, wait until it has reached the desired height, then stabilize the altitude with \c;jet(0);\n;.
-
-In order to "wait until it has reached the desired height", we need a conditional loop: the instructions inside the loop will be repeated only as long as a certain condition is true. The altitude of the bot is given by \c;position.z\n;. We already saw that \c;position\n; gives the position of the bot. And a position is given by the three coordinates x, y and z: the x-axis is the axis west-east, the y-axis is the axis south-north, and the z-axis is the vertical axis. Therefore we must wait while \c;position.z\n; is smaller than 20:
-\c;
-\s;	while (position.z < 20)
-\s;	{
-\s;		wait(0.2);

+\b;Objective
+As a defense against ants attacking from all sides, adapt the program \c;Spider2\n; in order to fly at a given altitude.
+
+\t;Program
+The program necessary for this task is somewhat similar to the program \c;Spider2\n; that looks for the closest ant, turns towards it and fires:
+\c;
+\s;extern void object::Spider2()
+\s;{	
+\s;	object    item;
+\s;	
+\s;	while (true)
+\s;	{
+\s;		item = radar(AlienSpider);
+\s;		turn(direction(item.position));
+\s;		fire(1);
+\s;	}
+\s;}
+\n;
+You can copy-paste it to the editor, and adapt it. Replace \c;radar(AlienSpider);\n; by \c;radar(AlienAnt);\n;, and write before the \c;while\n; loop another loop that activates the jet beneath the \l;winged shooter\u object\botfj; until the bot reaches an altitude of 20 meters.
+
+The instruction \c;\l;jet\u cbot\jet;()\n; controls the jet beneath winged bots. The number in brackets must range between \c;-1\n; and \c;1\n;.\c; jet(1);\n; moves the bot upward with maximum speed.\c; jet(-1);\n; moves the bot downward with maximum speed, and \c;jet(0);\n; stabilizes the altitude. As the bot must reach a precise altitude, move it upward slowly with \c;jet(0.2);\n;, wait until it has reached the desired height, then stabilize the altitude with \c;jet(0);\n;.
+
+In order to "wait until it has reached the desired height", we need a conditional loop: the instructions inside the loop will be repeated only as long as a certain condition is true. The altitude of the bot is given by \c;position.z\n;. We already saw that \c;position\n; gives the position of the bot. And a position is given by the three coordinates x, y and z: the x-axis is the axis west-east, the y-axis is the axis south-north, and the z-axis is the vertical axis. Therefore we must wait while \c;position.z\n; is smaller than 20:
+\c;
+\s;	while (position.z < 20)
+\s;	{
+\s;		wait(0.2);
+\s;	}
+\n;
+After waiting 0.2 seconds, the program will check if the altitude is still below 20 meters. If this is the case, it will wait a little more, if not, the program continues after the loop, i.e. after the closing brace \c;}\n;. Do not forget after the loop to stabilize the altitude with \c;jet(0);\n;.

-
-You can give the instruction \c;\l;radar\u cbot\radar();\n; more parameters (numbers) indicating where the radar should look for the ants. For example \c;radar(AlienAnt,0,360,0,40);\n; will only look for ants that are closer than 40 meters. The two first numbers tell the radar to search in all directions, the two last numbers tell the radar to detect only ants that are at a distance between 0 and 40 meters. If no ant is found that is closer than 40 meters, the instruction \c;\l;radar\u cbot\radar();\n; returns the value \c;null\n;. We can then write a conditional loop similar to the one written in the last exercise that waits as long as there is no ant closer than 40 meters:
-\c;
-\s;		while (radar(AlienAnt, 0, 360, 0, 40) == null)
-\s;		{
-\s;			wait(0.2);
-\s;		}
-\n;
-Notice that two equal signs "==" are needed to perform a comparison of equality.
-
-Just insert these lines before the instruction \c;fire(0);\n;, and the bot will wait before shooting until the ant is closer than 40 meters. Like this a regular power cell is enough to kill all ants.

-\b;Exercise
-Reach the finishing pad (25m in front of you) as fast as possible, using the instruction \c;motor( , )\n;. You will have to slow down progressively at the end of the move, otherwise the bot will get blown up on the \l;mines\u object\mine;.
-
-You could very well write no more than \c;\l;move\u cbot\move;(25);\n;, this would work perfectly well. However, the aim of this exercise is to learn how to use the instruction \c;\l;motor\u cbot\motor;\n;.
-
-This instruction asks for two values:
-1) The speed of the left-hand motor.
-2) The speed of the right-hand motor.
-
-\s;\c;	motor( left, right );
-\n;
-The values must range between -1 and 1:
--1 = full throttle backward
- 0 = stop
- 1 = full throttle forward
-
-For example, \c;motor(0.5, 0.5);\n; will move the motor forward with half-speed, until new instructions are given to the motors.
-
-With the instruction \c;motor(0.5, 0.6);\n;, the bot will move forward with half-speed, turning at the same time slightly to the left: the right-hand motor moves a little faster (\c;0.6\n;) than the left-hand motor (\c;0.5\n;).
-
-\b;General principle
-In order to move forward for exactly 25 meters and not more, you must move full speed during the first 23 meters, then reduce the speed of the motors progressively during the last two meters.
-The \l;variable\u cbot\var; \l;position\u cbot\object; gives you at any moment the current position of the bot, and the instruction \c;\l;distance\u cbot\dist;( , );\n; returns the distance between two points. The best way to know where you are consists in saving the current position before the start into a \l;variable\u cbot\var;, for example a variable called \c;start\n;. Then you can calculate the distance between the starting position and your current position with \c;distance(position, start)\n;.
-

-1) declare the variables
-\s;\c;	point start;
-\s;	float len;

-2) save the starting position
-\s;\c;	start = position;

-3) start full throttle :
-\s;\c;	motor(1, 1);

-4) Perform an infinite \c;\l;while\u cbot\while;\n; loop:
-\s;\c;	while ( true )
-\s;	{

-\s;		if ( len > 25-2 )
-\s;		{
-\s;			motor( less than before ! );
-\s;		}
-\s;	}
-\n;
-As long as the distance between the start and the current position is smaller than 23m, the instruction in braces after the \c;\l;if\u cbot\if;\n; instruction will not be executed, so the motors keep their maximum speed as they were told by the \c;\l;motor\u cbot\motor;(1,1);\n; instruction.
-
-In order to slow down progressively, the speed of the motors must be proportional to the remaining distance:
-o  \c;2.0\n; meters left -> speed = \c;1.00\n; (maximum)
-o  \c;1.5\n; meters left -> speed = \c;0.75\n;
-o  \c;1.0\n; meter left  -> speed = \c;0.50\n;
-o  \c;0.5\n; meter left  -> speed = \c;0.25\n;
-o  \c;0.0\n; meter left  -> speed = \c;0.00\n; (stop)
-
-\image tdragst1 12 6;
-You can use the following \l;expression\u cbot\expr; \c;(25-len)/2\n; in order to calculate the value for the speed instruction that must be given to the motors.

-\b;Exercise
-This exercise is very similar to the previous one. The bot must move exactly in the same way, but when writing the program, you must use a new concept that is extremely important in programming: \l;variables\u cbot\var;.
-We saw that all the pads are at a distance form each other of 20 meters. And all the rotations performed consist in 90 degree angles. Instead of rewriting the same values over and over again in the program, we can store them in a variable: 
-
-Instead of:
-\c;\s;	move(20);
-\s;	turn(90);
-\s;	move(20);
-\s;	turn(-90);
-\s;	...
-\n;
-We write :
-\c;\s;	dist = 20;
-\s;	dir = 90;
-\s;	move(dist);
-\s;	turn(dir);
-\s;	move(dist);
-\s;	turn(-dir);
-\s;	...
-\n;
-\b;Variables
-A \l;variable\u cbot\var; is composed of three elements: 
-1) The name
-2) The type of the content
-3) The content
-
-\t;The name
-Use the name to refer to a variable. For example, instead of writing \c;move(20);\n;, write \c;move(dist);\n;: "dist" is the name of the variable. You can choose almost any name for a variable, for example \c;dist\n;, \c;dir\n;, \c;p2\n;, \c;a\n;, \c;x\n;, \c;nothing_2_grab\n;, etc.
-
-\t;The type
-The type of a variable determines what kind of information the variable can contain. According to the type, a variable can contain a whole number, a real number, a character string, the coordinates of a point, etc. Here is a list with the most common variable types: 
-  o  \c;\l;int\u cbot\int;\n; for a whole number (12, -500, etc.)
-  o  \c;\l;float\u cbot\float;\n; for a real number (3.14, 0.2, -99.98, etc.)
-  o  \c;\l;string\u cbot\string;\n; for a character string ("Hello!", "Nothing to grab", etc.)
-  o  \c;\l;point\u cbot\point;\n; for the x,y,z-coordinates of a point in space
-  o  \c;\l;object\u cbot\object;\n; for the information about an object (bot, building, etc.) 
-
-\t;The content
-The content of a variable can be a number, a string, coordinates, etc., according to the type of the variable. The content of a variable can change many times during the execution of a program. 
-
-Before you can use a variable, you have to declare it. For example, before you can use the two variables \c;dist\n; and \c;dir\n;, you must declare them with the following lines: 
-\c;
-\s;	float  dist;
-\s;	float  dir;
-\n;
-Now you can use the two variables. To put the value 20 into \c;dist\n; and 90 into \c;dir\n;, write:
-\c;
-\s;	dist = 20;
-\s;	dir = 90;
-\n;
-Now you can move and turn the bot with the instructions \c;\l;move\u cbot\move;\n; and \c;\l;turn\n;\u cbot\turn;:
-\c;
-\s;	move(dist);
-\s;	turn(dir);
-\n;
-You can also use a whole \l;mathematical expression\u cbot\expr; instead of just the variable:
-\c;
-\s;	move(dist+100);
-\s;	turn(-dir);
-\n;
-The latter instruction will be needed to turn the bot right. 
-
-Now, rewrite the program of the previous exercise, but use a variable for the distance and another variable for the angle of the rotation. 
-
-\t;See also
-\l;Programming\u cbot;, \l;types\u cbot\type; and \l;categories\u cbot\category;.
+\b;Exercise
+This exercise is very similar to the previous one. The bot must move exactly in the same way, but when writing the program, you must use a new concept that is extremely important in programming: \l;variables\u cbot\var;.
+We saw that all the pads are at a distance form each other of 20 meters. And all the rotations performed consist in 90 degree angles. Instead of rewriting the same values over and over again in the program, we can store them in a variable: 
+
+Instead of:
+\c;\s;	move(20);
+\s;	turn(90);
+\s;	move(20);
+\s;	turn(-90);
+\s;	...
+\n;
+We write :
+\c;\s;	dist = 20;
+\s;	dir = 90;
+\s;	move(dist);
+\s;	turn(dir);
+\s;	move(dist);
+\s;	turn(-dir);
+\s;	...
+\n;
+\b;Variables
+A \l;variable\u cbot\var; is composed of three elements: 
+1) The name
+2) The type of the content
+3) The content
+
+\t;The name
+Use the name to refer to a variable. For example, instead of writing \c;move(20);\n;, write \c;move(dist);\n;: "dist" is the name of the variable. You can choose almost any name for a variable, for example \c;dist\n;, \c;dir\n;, \c;p2\n;, \c;a\n;, \c;x\n;, \c;nothing_2_grab\n;, etc.
+
+\t;The type
+The type of a variable determines what kind of information the variable can contain. According to the type, a variable can contain a whole number, a real number, a character string, the coordinates of a point, etc. Here is a list with the most common variable types: 
+  o  \c;\l;int\u cbot\int;\n; for a whole number (12, -500, etc.)
+  o  \c;\l;float\u cbot\float;\n; for a real number (3.14, 0.2, -99.98, etc.)
+  o  \c;\l;string\u cbot\string;\n; for a character string ("Hello!", "Nothing to grab", etc.)
+  o  \c;\l;point\u cbot\point;\n; for the x,y,z-coordinates of a point in space
+  o  \c;\l;object\u cbot\object;\n; for the information about an object (bot, building, etc.) 
+
+\t;The content
+The content of a variable can be a number, a string, coordinates, etc., according to the type of the variable. The content of a variable can change many times during the execution of a program. 
+
+Before you can use a variable, you have to declare it. For example, before you can use the two variables \c;dist\n; and \c;dir\n;, you must declare them with the following lines: 
+\c;
+\s;	float  dist;
+\s;	float  dir;
+\n;
+Now you can use the two variables. To put the value 20 into \c;dist\n; and 90 into \c;dir\n;, write:
+\c;
+\s;	dist = 20;
+\s;	dir = 90;
+\n;
+Now you can move and turn the bot with the instructions \c;\l;move\u cbot\move;\n; and \c;\l;turn\n;\u cbot\turn;:
+\c;
+\s;	move(dist);
+\s;	turn(dir);
+\n;
+You can also use a whole \l;mathematical expression\u cbot\expr; instead of just the variable:
+\c;
+\s;	move(dist+100);
+\s;	turn(-dir);
+\n;
+The latter instruction will be needed to turn the bot right. 
+
+Now, rewrite the program of the previous exercise, but use a variable for the distance and another variable for the angle of the rotation.

-You will have noticed that the way is made of "L"-shaped parts that are fit one into another. The first one (dark blue) measures two times 25 meters.

-\b;Exercise
-Let the bot find all the \l;blue crosses\u object\waypoint; on the ground. As soon as the bot passed over one of the crosses, it will disappear. Here is the general principle that you will apply:
-
-Repeat forever:
-	o  Look for a cross
-	o  If there is none, stop the program.
-	o  Calculate the direction of the cross.
-	o  Set the speed of the motors in such a way that they will find their way to the cross.
-
-\b;The program
-Use a \c;\l;while\u cbot\while;\n; loop in order to repeat several instructions over and over:
-\s;\c;while ( true )
-\s;{
-\s;	\n;instructions...\c;
-\s;}

-The instruction \c;\l;radar\u cbot\radar;\n; will detect the blue crosses and put their description into a variable, for example \c;spot\n;. In this case, \c;\l;radar\u cbot\radar;()\n; needs only one parameter, i.e. the category of the object that it must look for:
-\s;\c;spot = radar(WayPoint);
-\n;
-Once all the crosses have been found, \c;radar\n; will return the value \c;\l;null\u cbot\null;\n;. You will have to test this case and react accordingly with the instruction \c;\l;if\u cbot\if;\n;:
-\s;\c;if ( spot == null )  // no more ?
-\s;{
-\s;	motor(0, 0);  // stops the motors
-\s;	break;        // stops the loop
-\s;}
-\n;The instruction \c;\l;break\u cbot\break;\n; will stop the infinite loop \c;while (true)\n;.
-
-Use the instruction \c;\l;direction\u cbot\direct;()\n; to calculate the angle of the rotation that the bot must perform in order to turn towards the blue cross. The coordinates of the object are given by \c;spot.position\n;. The following line will put the angle of the necessary rotation into the \l;variable\u cbot\var; \c;dir\n;:
-\s;\c;dir = direction(spot.position);
-\n;
-The value of the angle is positive if the blue cross is on your left hand, and negative if it is on your right hand. If the cross to be reached is on your left hand, you must set the right-hand motor to full speed, and set the left-hand motor to a lower speed, according to the angle:
-

-
-The graphic below shows the speed of the left-hand and right-hand motor as set by the instruction \c;\l;motor\u cbot\motor;\n;, according to the angle:
-
-\image radar2 14 10;
-If the cross is straight ahead, the angle is 0 degrees. The motors will get the speeds 1 and 1, which means full speed ahead.

You can use the \l;expression\u cbot\expr; \c;1+dir/90\n; in order to calculate the necessary speed of the motors:
-\s;\c;if ( dir < 0 )  // on the right side?
-\s;{
-\s;	motor(1, 1+dir/90);  // turns more or less

-\b;Exercise
-Remote control a robot using an \l;information exchange post\u object\exchange;, so it will transport \l;uranium ore\u object\uranore;.
-The main actors of this exercise are¦:
-
-1) A \l;sniffer\u object\botsr; (can't carry anything).
-2) An \l;information exchange post\u object\exchange; that receives information from a sender and then transmits it to a receiver.
-3) A \l;grabber\u object\botgr; which waits for orders from the exchange post. You have no way control this robot directly.
-
-\image tremot1a 16 8;
-An information exchange post stores "name/value" couples. To control the "slave" robot we use just one couple¦:
-
-    name="order", valuer=order number
-
-The slace robot understands following orders¦:
-\c;
-    1 -> grab();     // take an object
-    2 -> drop();     // drop an object
-    3 -> move(10);   // move 10 meters forward
-    4 -> move(-10);  // move 10 meters backwards
-\n;
-To instruct the slave to move forward 10 meters all you have to do is¦:
-\c;\s;	\l;send\u cbot\send;("order", 3, 100);  // order 3 -> "move(10)"
-\n;
-After the send instruction we wait for 5 seconds to be sure the move is done.

-\n;
-Remark: There is a better way for waiting the order has been executed, but we'll see this later in exercise "Remote Control #2".

-1) Take the uranium ore
-2) Move forward by 10 meters
-3) Drop the uranium ore

-\b;Exercice
-Remote control a slave robot without using an \l;information exchange post\u object\exchange;. The robot should pass over the 6 blue crosses. You must use a \l;string\u cbot\string; to pass the orders to the slave bot. This string contains the order the slave shoud execute, for exemple \c;"move(20)"\n;. You can see that this is the same syntax as used in the CBOT language but we could have chosen any other syntax for exemple something like \c;"advance=20"\n;. The string will be a \c;\l;static\u cbot\static;\n; class member that will be used to communicate from the master to the slave.
-
-The two main actors of this exercise are:
-1) The \l;wheeled grabber\u object\botgr; without an energy pack and therefore immobile. This is the master you should program so it will transmit orders to the slave.

-First of all we must understand how the program of the slave works. The \l;class\u cbot\class; \c;exchange\n; contains the mechanism for exchaning the orders. We declare a \c;\l;static\u cbot\static;\n; class member \c;m_order\n; which will contain the order to be executed.

-\n;The \c;put\n; method will be used by the master robot for transmitting an order. As long as the string \c;m_order\n; is not empty, the slave has not finished the order and the \c;put\n; method will return \c;false\n; and will do nothing.

-\s;		{
-\s;			return false;
-\s;		}
-\s;	}
-\n;
-Another method \c;get\n; will be used by the slave to retrieve the orders. This method returns the string contained in \c;m_order\n; and empties it, so a new order can be accepted:

-\c;\s;	\l;synchronized\u cbot\synchro; string get()
-\s;	{
-\s;		string ret = m_order;
-\s;		m_order = "";

-\c;\s;\l;extern\u cbot\extern; void object::Slave3( )
-\s;{
-\s;	exchange list();
-\s;	string   todo;
-\n;
-The outer \c;while\n; loop lasts for ever. The inner \c;while\n; loop waits for an order by using the \c;get\n; method of the \c;exchange\n; class. As soon as \c;get\n; returns a non empty string, the while loop stops.

-\c;\s;		if ( \l;strfind\u cbot\strfind;(todo, "move") == 0 )
-\s;		{

-First of all we must understand how the program of the slave works. The \l;class\u cbot\class; \c;order\n; contains two members: \c;m_type\n; is the order to execute (move or turn) and \c;m_param\n; is the distance to move or the rotation angle¦:

-\s;{
-\s;	\l;static\u cbot\static; \l;private\u cbot\private; order m_order = new order;
-\n;
-\n;The \c;put\n; method will be used by the master robot for transmitting an order. As long as \c;m_order\n; is different from \c;\l;nan\u cbot\nan;\n;, the slave has not finished the order and the \c;put\n; method will return \c;false\n; and will do nothing¦:
-

-\s;			m_order = a;
-\s;			return true;
-\s;		}
-\s;		else
-\s;		{
-\s;			return false;
-\s;		}
-\s;	}
-\n;
-Another method \c;get\n; will be used by the slave to retrieve the orders. This method returns the order to be executed:
-
-\c;\s;	\l;synchronized\u cbot\synchro; order get()
-\s;	{
-\s;		return m_order;
-\s;	}
-\n;
-A third method \c;delete\n; will be used by the slave to indicate that the order has been executed:
-
-\c;\s;	\l;synchronized\u cbot\synchro; void delete()
-\s;	{
-\s;		m_order.m_type = nan;
-\s;	}
-\s;}
-\n;
-The main program of the slave contains an instance of the class \c;exchange\n; called \c;list\n;. We put () after the word \c;list\n; in order to create an instance of the class \c;exchange\n;.
-
-\c;\s;\l;extern\u cbot\extern; void object::Slave3( )
-\s;{
-\s;	exchange list();
-\s;	order    todo;
-\n;
-The outer \c;while\n; loop lasts for ever. The inner \c;while\n; loop waits for an order by using the \c;get\n; method of the \c;exchange\n; class. As soon as \c;get\n; returns a value different from \c;nan\n;, the while loop stops.

-\s;		{
-\s;			move(todo.m_param);

-\s;		{
-\s;			turn(todo.m_param);
-\s;		}
-\s;		else
-\s;		{
-\s;			message("Unknown order");

+\b;Exercise
+Remote control a slave robot without using an \l;information exchange post\u object\exchange;. The robot should pass over the 6 blue crosses. You must use a \c;\l;static\u cbot\static;\n; variable to pass the orders to the slave bot.
+
+The two main actors of this exercise are:
+1) The \l;wheeled grabber\u object\botgr; without an energy pack and therefore immobile. This is the master you should program so it will transmit orders to the slave.
+2) The slave \l;practice bot\u object\bottr; which is already programmed and just waits for orders from the master.
+
+\b;The slave
+First of all we must understand how the program of the slave works. The \l;class\u cbot\class; \c;order\n; contains two members: \c;m_type\n; is the order to execute (move or turn) and \c;m_param\n; is the distance to move or the rotation angle¦:
+
+\c;\s;\l;public\u cbot\public; \l;class\u cbot\class; order
+\s;{
+\s;	\l;int\u cbot\int;    m_type = \l;nan\u cbot\nan;;
+\s;	\l;float\u cbot\float;  m_param;
+\s;}
+\n;
+A second \l;class\u cbot\class; \c;exchange\n; contains the mechanism for exchanging the orders. We declare a \c;\l;static\u cbot\static;\n; class member \c;m_order\n; which will contain the order to be executed. The word \c;static\n; insures that the member \c;m_order\n; is shared between all instances of the \l;class\u cbot\class; exchange.
+
+\c;\s;\l;public\u cbot\public; \l;class\u cbot\class; exchange
+\s;{
+\s;	\l;static\u cbot\static; \l;private\u cbot\private; order m_order = new order;
+\n;
+\n;The \c;put\n; method will be used by the master robot for transmitting an order. As long as \c;m_order\n; is different from \c;\l;nan\u cbot\nan;\n;, the slave has not finished the order and the \c;put\n; method will return \c;false\n; and will do nothing¦:
+
+\c;\s;	\l;synchronized\u cbot\synchro; \l;bool\u cbot\bool; put(order a)
+\s;	{
+\s;		if ( m_order.m_type == nan )
+\s;		{
+\s;			m_order = a;
+\s;			return true;
+\s;		}
+\s;		else
+\s;		{
+\s;			return false;
+\s;		}
+\s;	}
+\n;
+Another method \c;get\n; will be used by the slave to retrieve the orders. This method returns the order to be executed:
+
+\c;\s;	\l;synchronized\u cbot\synchro; order get()
+\s;	{
+\s;		return m_order;
+\s;	}
+\n;
+A third method \c;delete\n; will be used by the slave to indicate that the order has been executed:
+
+\c;\s;	\l;synchronized\u cbot\synchro; void delete()
+\s;	{
+\s;		m_order.m_type = nan;
+\s;	}
+\s;}
+\n;
+The main program of the slave contains an instance of the class \c;exchange\n; called \c;list\n;. We put () after the word \c;list\n; in order to create an instance of the class \c;exchange\n;.
+
+\c;\s;\l;extern\u cbot\extern; void object::Slave3( )
+\s;{
+\s;	exchange list();
+\s;	order    todo;
+\n;
+The outer \c;while\n; loop lasts for ever. The inner \c;while\n; loop waits for an order by using the \c;get\n; method of the \c;exchange\n; class. As soon as \c;get\n; returns a value different from \c;nan\n;, the while loop stops.
+
+\c;\s;	\l;while\u cbot\while; ( true )
+\s;	{
+\s;		\l;while\u cbot\while; ( true )
+\s;		{
+\s;			todo = list.get();
+\s;			if ( todo.m_type != nan )  break;
+\s;			wait(1);
+\s;		}
+\n;
+Now we have received the order in the \c;todo\n; variable. All we have to do is execute it:
+
+\c;\s;		if ( todo.m_type == 1 )
+\s;		{
+\s;			move(todo.m_param);
+\s;		}
+\s;		else if ( todo.m_type == 2 )
+\s;		{
+\s;			turn(todo.m_param);
+\s;		}
+\s;		else
+\s;		{
+\s;			message("Unknown order");
+\s;		}
+\n;
+As soon as the execution of the order is finished, we must call the \c;delete\n; method so the master knows that another order can be sent¦:

+\c;\s;		list.delete();

-This exercise is very similar to the previous one. There are now three \l;titanium cubes\u object\titan; that you must move to 3 finishing pads. Here are the coordinates of the finishing pads:

-\b;General principle
-Repeat 3 times:

-\s;aim(0);\n;
-\n;Puts the cannon straight.
-\c;
-\s;turn();\n;
-\n;Executes a rotation of a certain angle, given in brackets in degrees. For example \c;turn(90);\n; will turn the bot 90 degrees to the left, i.e. a quarter turn to the left. \c;turn(-90);\n; will turn the bot 90 degrees to the right (quarter turn right). Positive values turn left, negative values turn right. \c;turn(180);\n; will make the bot face in the opposite direction.
-\c;
-\s;fire(1);
-\n;Shoots the cannon. The number in brackets indicates the duration of the burst. In most cases, shoot a burst of 1 second.

-
-\t;Remarks
-Be careful to write the instructions precisely, respecting lower and upper case letters.
-
-Always write one instruction per line, finishing each line with a semicolon.

+Be careful to write the instructions precisely, respecting lower and upper case letters.
+
+Always write one instruction per line, finishing each line with a semicolon.
+
+In case your program does not do exactly what you wanted, you can put the bot back at the starting point with the \button 59; button. You can also start over again from the beginning (hit the "Esc" key, then click "Restart"). The program you have written will not be lost.

-The many failures are due to the fact that the wasp is already gone before the bullets can reach it. The only way to improve the program consists in setting the power of the two motors and of the jet in such a way that the bot follows the movement of the target during the burst.
-
-Just before the shot, the program adjusts a last time the direction with \c;turn(direction(item.position));\n;. In order to follow the wasp during the burst, you have to "remember" the angle of this last rotation: if the angle was positive (rotation to the left), the bot must continue to turn left during the burst; if the angle was negative, the bot must continue to turn right.
-
-In order to "remember" the angle of the last rotation, we need a variable that can contain just one number. If we choose to call it \c;angle\n;, we must define the variable with the following line at the beginning of the program:
-\c;
-\s;	\l;float\u cbot\type; angle;
-\n;
-The variable type \l;float\u cbot\type; is the variable type that can contain any number, i.e. whole numbers or real numbers. Please refer to the \l;text about variable types\u cbot\type; if you want to know more about the different types of variables and what they can contain.
-
-Just before the instruction \c;fire(1);\n;, instead of writing \c;\l;turn\u cbot\turn;(\l;direction\u cbot\direct;(item.position));\n;, we will put the rotation angle into the variable \c;angle\n;:
-\c;
-\s;	angle = direction(item.position);

+\b;Objective
+Bring down the flying wasps in a more efficient way than with the previous program.
+
+\b;Program
+Here is again the program of the previous exercise that shoots down all the wasps after many, many unsuccessful attempts:
+\c;
+\s;extern void object::Wasp1()
+\s;{
+\s;	\l;object\u cbot\type;    item;
+\s;	
+\s;	\l;aim\u cbot\aim;(0);
+\s;	
+\s;	\l;while\u cbot\while; (true)
+\s;	{
+\s;		\l;while\u cbot\while; (\l;radar\u cbot\radar;(AlienWasp, 0, 360, 0, 20) == null)
+\s;		{
+\s;			item = \l;radar\u cbot\radar;(AlienWasp);
+\s;			\l;turn\u cbot\turn;(\l;direction\u cbot\direct;(item.position));
+\s;			\l;motor\u cbot\motor;(1,1);
+\s;			
+\s;			\l;jet\u cbot\jet;(0);
+\s;			\l;if\u cbot\if; (position.z > item.position.z)
+\s;			{
+\s;				\l;jet\u cbot\jet;(-0.3);
+\s;			}
+\s;			
+\s;			\l;if\u cbot\if; (position.z < item.position.z - 1)
+\s;			{
+\s;				\l;jet\u cbot\jet;(0.3);
+\s;			}
+\s;			
+\s;			\l;wait\u cbot\wait;(0.2);
+\s;		}
+\s;		item = \l;radar\u cbot\radar;(AlienWasp);
+\s;		\l;turn\u cbot\turn;(\l;direction\u cbot\direct;(item.position));
+\s;		\l;fire\u cbot\fire;(1);
+\s;	}
+\s;}
+\n;
+The many failures are due to the fact that the wasp is already gone before the bullets can reach it. The only way to improve the program consists in setting the power of the two motors and of the jet in such a way that the bot follows the movement of the target during the burst.
+
+Just before the shot, the program adjusts a last time the direction with \c;turn(direction(item.position));\n;. In order to follow the wasp during the burst, you have to "remember" the angle of this last rotation: if the angle was positive (rotation to the left), the bot must continue to turn left during the burst; if the angle was negative, the bot must continue to turn right.
+
+In order to "remember" the angle of the last rotation, we need a variable that can contain just one number. If we choose to call it \c;angle\n;, we must define the variable with the following line at the beginning of the program:
+\c;
+\s;	\l;float\u cbot\type; angle;
+\n;
+The variable type \l;float\u cbot\type; is the variable type that can contain any number, i.e. whole numbers or real numbers. Please refer to the \l;text about variable types\u cbot\type; if you want to know more about the different types of variables and what they can contain.
+
+Just before the instruction \c;fire(1);\n;, instead of writing \c;\l;turn\u cbot\turn;(\l;direction\u cbot\direct;(item.position));\n;, we will put the rotation angle into the variable \c;angle\n;:
+\c;
+\s;	angle = direction(item.position);
+\n;
+Then we perform the rotation, and we set the power of the motors so that the bot continues the movement:
+\c;
+\s;	turn(angle);
+\s;	if (angle < 0)
+\s;	{
+\s;		motor(1,0.5);
+\s;	}
+\s;	else
+\s;	{
+\s;		motor(0.5,1);
+\s;	}
+\n;
+The instruction \c;else\n; determines what instructions the program should execute if the condition stated in the \c;if\n; instruction is false.
+
+Then we must set the power of the jet so that the bot follows the wasp also in the vertical direction:
+\c;
+\s;	jet(0);
+\s;	if(position.z > item.position.z)
+\s;	{
+\s;		jet(-0.3);
+\s;	}
+\s;	
+\s;	if(position.z < item.position.z - 1)
+\s;	{
+\s;		jet(0.3);
+\s;	}
+\n;
+As you will see, this program is much more efficient than the previous one!
