Available since: Gideros 2011.6
Class: b2

Description

Creates and returns a revolute joint definition table with the bodies, local anchors, and reference angle using a world anchor point.

(Please refer to b2.World:createJoint function for more information about all the information needed to create a revolute joint). <syntaxhighlight lang="lua"> (table) = b2.createRevoluteJointDef(bodyA,bodyB,anchorx,anchory) </source>

Parameters

bodyA: (b2.Body) the first attached body
bodyB: (b2.Body) the second attached body
anchorx: (number) the x coordinate of the world anchor point
anchory: (number) the y coordinate of the world anchor point

Return values

Returns (table) a new revolute joint definition table

Examples

Revolute joint <syntaxhighlight lang="lua"> --create empty box2d body for joint local ground = world:createBody({}) ground:setPosition(300, 480)

local jointDef = b2.createRevoluteJointDef(body, ground, 300, 300) local revoluteJoint = world:createJoint(jointDef) --will not let ball spin forever revoluteJoint:setMaxMotorTorque(1) revoluteJoint:enableMotor(true) </source>
