Description
Friction joint. This is used for top-down friction. It provides 2D translational friction and angular friction.
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)
Methodsb2.FrictionJoint:getMaxForce - returns the maximum friction force in N |
