\b;Instruction \c;public\n; (for specialists) This instruction has two distinct purposes¦: 1) Make a function available to other bots. 2) Make a class member accessible from outside the class definition. \b;Instruction \c;public\n; for functions If you put \c;public\n; before a \l;function\u cbot\function; definition, you can make the function available to programs in other bots in the same mission. For example in the first bot we would have¦: \c; \s;public void object::Segment(float dist, float angle) \s;{ \s; move(dist); \s; turn(angle); \s;} \n; And in another bot we would have¦: \c; \s;extern void object::Square( ) \s;{ \s; for ( int i=0 ; i<4 ; i++ ) \s; { \s; Segment(10, 90); \s; fire(1); \s; } \s;} \n; If you have declared a function \c;public\n;, you cannot define a function with the same name and arguments in another bot of the same mission. If a bot containing a \c;public\n; function is destroyed, the other bots that make use of this function will be stopped with an error. \b;Instruction \c;public\n; for classes \l;Class\u cbot\class; members can be public (by default) or \l;privat\u cbot\private;. A member can be declared private by putting \c;private\n; before the member type. Private members are not accessible from outside the class definition. \c; \s;public class MyClass \s;{ \s; int b; // public by default \s; public int a; // also public \s; private point position; // privat \s;} \s;void Test() \s;{ \s; MyClass item; \s; item.a = item.b = 12; // ok \s; message( item.position ); // this is an error \s;} \n; \t;See also \c;\l;class\u cbot\class;\n;, \c;\l;private\u cbot\private;\n;, \c;\l;functions\u cbot\function;\n; \l;Programming\u cbot;, \l;types\u cbot\type; and \l;categories\u cbot\category;.
