Evade Class Reference

Description

Evade anticipates where the percept will be in the future and flees from this position (back-end class).

It functions analogously to the usual steering behaviour 'Evade'. It is the counterpart to Pursue. Instead of moving towards a predicted position, it flees from it. Therefore, it inherits from Pursue and negate its SteeringBehaviour.ResultDirection.

Back-end class of AIMEvade. This behaviour is thread-safe.
