blaze.dynamics.joints.pulleyJoint

class PulleyJointDef : blaze.dynamics.joints.joint.JointDef;

Pulley joint definition. This requires two ground anchors,

two dynamic body anchor points, max lengths for each side,

and a pulley ratio.

this(Body b1, Body b2, bVec2 ga1, bVec2 ga2, bVec2 anchor1, bVec2 anchor2, float r);

Initialize the bodies, anchors, lengths, max lengths, and ratio using the world anchors.

bVec2 groundAnchor1 ;

The first ground anchor in world coordinates. This point never moves.

bVec2 groundAnchor2 ;

The second ground anchor in world coordinates. This point never moves.

bVec2 localAnchor1 ;

The local anchor point relative to body1's origin.

bVec2 localAnchor2 ;

The local anchor point relative to body2's origin.

float length1 ;

The a reference length for the segment attached to body1.

float maxLength1 ;

The maximum length of the segment attached to body1.

float length2 ;

The a reference length for the segment attached to body2.

float maxLength2 ;

The maximum length of the segment attached to body2.

float ratio ;

The pulley ratio , used to simulate a block-and-tackle.

class PulleyJoint : blaze.dynamics.joints.joint.Joint;

The pulley joint is connected to two bodies and two fixed ground points.

The pulley supports a ratio such that:

length1 + ratio * length2 <= constant

Yes, the force transmitted is scaled by the ratio.

The pulley also enforces a maximum length limit on both sides. This is

useful to prevent one side of the pulley hitting the top.
