Available since: Gideros 2019.10
Class: R3d.Fixture

Description

Sets the fixture material (bounciness, frictionCoefficient, rollingResistance).

r3d.Fixture:setMaterial(material)
warnings: not setting material.bounciness between (0, 1) will crash your app!
warnings: setting material.frictionCoefficient a negative value will crash your app!
warnings: material.rollingResistance is deprecated use R3d.Body:setAngularDamping instead

Parameters

material: (table) the fixture material table

Example

-- the body
view.body = xworld:createBody(view:getMatrix())
local shape = r3d.SphereShape.new(params.sizex) -- radius
local fixture = view.body:createFixture(shape, nil, params.mass)
-- materials default: bounciness=0.5, frictionCoefficient=0.3, rollingResistance=0
local mat = fixture:getMaterial()
mat.bounciness = 0.1 -- 0 = no bounciness, 1 = max bounciness
mat.frictionCoefficient = 0.5 -- 0 = no friction
--mat.rollingResistance = 0.1 -- DEPRECATED!
fixture:setMaterial(mat)
