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).
(table) = b2.createRevoluteJointDef(bodyA,bodyB,anchorx,anchory)
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
--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)
