\b;Exercise You must find a way to destroy the four moving \l;target bots\u object\bottarg; without wasting one shot. Notice that after every move, the targets will stay motionless during one second. \b;General principle 1) Detect a target with the instruction \c;\l;radar\u cbot\radar;(TargetBot);\n;. 2) Turn towards the target with \c;\l;turn\u cbot\turn;(direction());\n;. 3) After the rotation, check if the target did not move. 4) If it did not, wait 0.2 seconds with \c;\l;wait\u cbot\wait;(0.2);\n;. 5) Re-check if the target did not move. 6) If it did not, shoot with \c;\l;fire\u cbot\fire;(2);\n; and wait 2 seconds for the target to be hit by the bullets and destroyed. There are of course other ways to achieve the goal. \b;Remark In order to increase the efficiency of your shots, aim a little downward with \c;\l;aim\u cbot\aim;(-3);\n;. \t;See also \l;Programming\u cbot;, \l;types\u cbot\type; and \l;categories\u cbot\category;.
