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).
(table) = b2.createFrictionJointDef(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 friction joint definition table
Examples
Friction joint
--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)
