Member Data Documentation

float32 dampingRatio

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

float32 frequencyHz

The response speed.

float32 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 target

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