Available since: Gideros 2011.6
Class: b2
Description
Creates and returns a friction joint definition table with the bodies and local anchors using a world anchor point.
(Please refer to b2.World:createJoint function for more information about all the information needed to create a friction joint). <syntaxhighlight lang="lua"> (table) = b2.createFrictionJointDef(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 friction joint definition table
Examples
<syntaxhighlight lang="lua"> --create empty box2d body for joint local ground = world:createBody({}) ground:setPosition(350, 480)
--create friction joint local jointDef = b2.createFrictionJointDef(body, ground, 350, 200) local frictionJoint = world:createJoint(jointDef)
--set maximum friction force to slow down the ball frictionJoint:setMaxForce(100) </source>
