Available since: Gideros 2011.6
Class: b2

### Description

Creates and returns a pulley joint definition table with the bodies, anchors, lengths, max lengths, and ratio using the world anchors.

```(table) = b2.createPulleyJointDef(bodyA,bodyB,groundAnchorAx,groundAnchorAy,groundAnchorBx,groundAnchorBy,anchorAx,anchorAy,anchorBx,anchorBy,ratio)
```

### Parameters

bodyA: (b2.Body) the first attached body
bodyB: (b2.Body) the second attached body
groundAnchorAx: (number) the x coordinate of the first ground anchor in world coordinates. This point never moves.
groundAnchorAy: (number) the y coordinate of the first ground anchor in world coordinates. This point never moves.
groundAnchorBx: (number) the x coordinate of the second ground anchor in world coordinates. This point never moves.
groundAnchorBy: (number) the y coordinate of the second ground anchor in world coordinates. This point never moves.
anchorAx: (number) the x coordinate of the world anchor point of bodyA
anchorAy: (number) the y coordinate of the world anchor point of bodyA
anchorBx: (number) the x coordinate of the world anchor point of bodyB
anchorBy: (number) the y coordinate of the world anchor point of bodyB
ratio: (number) the pulley ratio, used to simulate a block-and-tackle

### Return values

Returns (table) A new pulley joint definition table

### Examples

Pulley joint

```--create empty box2d body for joint
local ground = world:createBody({})

local jointDef = b2.createPulleyJointDef(body1, body2,
200, 100, --coordinates where "imaginary string" is attached in the air for body 1
350, 100, --coordinates where "imaginary string" is attached in the air for body 2
200, 300, --coordinates where "imaginary string" is attached to the body 1
350, 300, --coordinates where "imaginary string" is attached in the body 2
1) -- ratio (if < 1 -> makes body 2 heavier, > 1 makes body 1 heavier, =1 makes them equal
local pulleyJoint = world:createJoint(jointDef)
```
