Create a pulley joint to join two bodies to each other and the ground.

The pulley joint simulates a pulley with an optional block and tackle. If the ratio parameter has a value different from one, then the simulated rope extends faster on one side than the other. In a pulley joint the total length of the simulated rope is the constant length1 + ratio * length2, which is set when the pulley joint is created.

Pulley joints can behave unpredictably if one side is fully extended. It is recommended that the method setMaxLengths  be used to constrain the maximum lengths each side can attain.

Function

Synopsis

joint = newPulleyJoint( body1, body2, gx1, gy1, gx2, gy2, x1, y1, x2, y2, ratio )

Arguments

Body body1
The first body to connect with a pulley joint.
Body body2
The second body to connect with a pulley joint.
number gx1
The x coordinate of the first body's ground anchor.
number gy1
The y coordinate of the first body's ground anchor.
number gx2
The x coordinate of the second body's ground anchor.
number gy2
The y coordinate of the second body's ground anchor.
number x1
The x coordinate of the pulley joint anchor in the first body.
number y1
The y coordinate of the pulley joint anchor in the first body.
number x2
The x coordinate of the pulley joint anchor in the second body.
number y2
The y coordinate of the pulley joint anchor in the second body.
number ratio
The joint ratio.

Returns

Joint joint
The new pulley joint.
