Description
A distance joint constrains two points on two bodies to remain at a fixed distance from each other. You can view this as a massless, rigid rod.
Examples
Distance joint
local jointDef = b2.createDistanceJointDef(body1, body2, 100, 100, 200, 100)
local distanceJoint = world:createJoint(jointDef)
--by default length between two bodies is the length they have between them when joint was created
--but it is possilbe to change it using
distanceJoint:setLength(200)
distanceJoint:setDampingRatio(0.5)
distanceJoint:setFrequency(4)
Methodsb2.DistanceJoint:getDampingRatio returns the damping ratio |
