AIBehaviors

from panda3d.ai import AIBehaviors

class AIBehaviors

Bases: DTOOL_SUPER_BASE

This class implements all the steering behaviors of the AI framework, such as seek, flee, pursue, evade, wander and flock. Each steering behavior has a weight which is used when more than one type of steering behavior is acting on the same ai character. The weight decides the contribution of each type of steering behavior. The AICharacter class has a handle to an object of this class and this allows to invoke the steering behaviors via the AICharacter. This class also provides functionality such as pausing, resuming and removing the AI behaviors of an AI character at anytime.
