Class: b2.Contact
Description
Overrides the default friction fixture. You can call this in pre-solve event. This value persists until set or reset. <syntaxhighlight lang="lua"> b2.Contact:setFriction(friction) </source>
Parameters
friction: (number) the new friction value
Example
<syntaxhighlight lang="lua"> function LevelX:onPreSolveContact(e) local bodyA = e.fixtureA:getBody() local bodyB = e.fixtureB:getBody() local platform, playable if bodyA.name == G_PTPLATFORM then platform = bodyA playable = bodyB elseif bodyB.name == G_PTPLATFORM then platform = bodyB playable = bodyA end if not platform then return end e.contact:setFriction(0.4) -- here ;-) end </source>
