Field Detail

target

public final Vec2 target

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

maxForce

public float 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).

frequencyHz

public float frequencyHz

The response speed.

dampingRatio

public float dampingRatio

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