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)

Methods

b2.FrictionJoint:getMaxForce returns the maximum friction force in N
b2.FrictionJoint:getMaxTorque returns the maximum friction torque in N*m
b2.FrictionJoint:setMaxForce sets the maximum friction force in N
b2.FrictionJoint:setMaxTorque sets the maximum friction torque in N*m
