Class: b2.Contact
Description
Overrides the default friction fixture. You can call this in pre-solve event. This value persists until set or reset.
b2.Contact:setFriction(friction)
Parameters
friction: (number) the new friction value
Example
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 ;-)
