I am using Box2d v2.3 The following box2d method takes a bool "wake" :
inline void b2Body::ApplyLinearImpulse(const b2Vec2& impulse, const b2Vec2& point, bool wake)
What does it do? Regardless of whether I set it to YES or NO, it doesn't seem to noticeable impact my physics.
Earlier versions of Box2d did not accept the bool - they only took impulse and point.
EDIT: Likewise so does the following method:
inline void b2Body::ApplyForce(const b2Vec2& force, const b2Vec2& point, bool wake)
