Member Data Documentation

float32 b2MouseJointDef::dampingRatio

The damping ratio. 0 = no damping, 1 = critical damping.

float32 b2MouseJointDef::frequencyHz

The response speed.

float32 b2MouseJointDef::maxForce

The maximum constraint force that can be exerted to move the candidate body. Usually you will express as some multiple of the weight (multiplier * mass * gravity).

b2Vec2 b2MouseJointDef::target

The initial world target point. This is assumed to coincide with the body anchor initially.
