 msgid "CBOT uses references for <a cbot|class>classes</a> and <a cbot|array>arrays</a>. Any class variable actually contains a reference to the instance. The instance actually contains the class fields. Several references can reference the same instance. A <code><a cbot|null>null</a></code> reference references nothing. You can compare an instance to a suitcase and a reference to a carrier. Each time we need a new suitcase we create a new instance with a carrier. But a suitcase can be carried by more than one carrier. A carrier who carries no suitcase is a <code><a cbot|null>null</a></code> reference."
 msgstr "CBOT использует ссылки для <a cbot|class>классов</a> и <a cbot|array>массивов</a>. Любой класс содержит в себе ссылку на данный экземпляр. Экземпляр на самом деле содержит в себе ячейки классов. Некоторые ссылки могут ссылаться на ту же функцию. <code><a cbot|null>null</a></code> ссылка не ссылается ни на что. Например, каждый раз, когда нам нужет новый чемодан, мы создаем новый экземпляр перевозчика. Но чемодан может перевозиться более чем на одном носителе. Перевозчик, не имеющий груза имеет <code><a cbot|null>null</a></code> ссылку."

 msgid "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 <code>countTit</code>. This variable must contain only whole numbers, so choose the type <code>int</code>. At the beginning of the program, you must declare the variable. Then you put the value <code>0</code> into the variable, and every time you grab a titanium ore, you increase the variable by <code>1</code>. At every moment, the variable contains the number of titanium ore units that the grabber collected."
 msgstr "Например вы можете использовать переменную для того, чтобы сосчитать количество единиц титановой руды, которое сборщик собрал и отнес в переработчик. Вначале вы должны придумать для нее имя: имя должно быть не очень длинным и при этом говорить о том, для чего используется эта переменная. Давайте назовем ее <code>countTit</code>. Эта переменная может содержать только целые числа, поэтому выберем тип <code>int</code>. Переменную нужно объявить в начале программы. Затем нужно сохранить в переменной значение <code>0</code> и каждый раз, когда вы будете подбирать титановую руду, увеличивать ее значение на <code>1</code>. В каждый момент времени переменная будет содержать количество единиц титановой руды, которую собрал сборщик."

В этом условном цикле вы должны найти ближайшего муравья, развернуться в его сторону, разогнать моторы на полную мощность <c/>motor(1,1);<n/>, и немного подождать, например, 0.2 секунды. Все эти инструкции должны повторяться до тех пор, пока муравей не приблизиться к вам на расстояние менее 20 метров. После этого вы должны просто выстрелить в него."

 msgstr "Pour que le shooter soit capable d'attraper des guêpes en vol, il faut faire quelques changements. Il faut remplacer tous les <code><a cbot|radar>radar</a>(AlienAnt)</code> par <code>radar(AlienWasp)</code>. Le canon doit viser tout droit et non pas vers le bas, remplacez <c/><a cbot|aim>aim</a>(-20);<n/> par <c/>aim(0);<n/>. Et le robot doit voler à la même altitude que la guêpe. Pour cela, il faut comparer l'altitude du robot donnée par <code>position.z</code> avec l'altitude de la guêpe donné par <code>chose.position.z</code>. Si <code>position.z > chose.position.z</code>, il faut descendre doucement avec <c/><a cbot|jet>jet</a>(-0.3);<n/>.
