bool Britbot.EnemyGroup.IsApproachingIsland ( SmartIsland sIsland ) [inline]

This method checks if this enemy group could be approaching the given island first checks if it moves in the general direction of the island compares difference in trajectory to a MAGIC constant.

Parameters:

sIsland the island we check

Returns:: true if it is possible that the enemy is approching the island
