Imports

com.badlogic.gdx.math.Vector2, com.badlogic.gdx.physics.box2d.Body, .JointDef

Pulley joint definition. This requires two ground anchors, two dynamic body anchor points, max lengths for each side, and a pulley ratio.

Field Summary

Modifier and Type	Field and Description
public final Vector2	groundAnchorA The first ground anchor in world coordinates.
public final Vector2	groundAnchorB The second ground anchor in world coordinates.
public float	lengthA The a reference length for the segment attached to bodyA.
public float	lengthB The a reference length for the segment attached to bodyB.
public final Vector2	localAnchorA The local anchor point relative to bodyA's origin.
public final Vector2	localAnchorB The local anchor point relative to bodyB's origin.
private static final float	minPulleyLength
public float	ratio The pulley ratio, used to simulate a block-and-tackle.
