Available since: Gideros 2011.6
Class: b2.DistanceJoint
Description
Sets the damping ratio of this distance joint. 0 = no damping, 1 = critical damping. <source lang="lua"> b2.DistanceJoint:setDampingRatio(ratio) </syntaxhighlight>
For a rigid distance joint you would set the frequency equals to 0 and the damping equals to 1.
Parameters
ratio: (number) the damping ratio (usually between 0 and 1)
Example
This is some code from an actual game ;-) <source lang="lua"> self.body.ground = self.world:createBody({}) if g_currentlevel == 2 then self.body.ground:setPosition(xposx, xposy) local jointDef = b2.createDistanceJointDef(self.body.ground, self.body, xposx + 0, xposy - 64, xposx, xposy) self.body.joint = self.world:createJoint(jointDef) self.body.joint:setDampingRatio(0.5) self.body.joint:setFrequency(1.2) end </syntaxhighlight>
