This function sets a surface material.

Syntax

Parameters

Returns

This function will increment the reference count of the new material and decrement the reference count of the old material (if they exist).

Example

--Create a window
window = Window:Create()
context = Context:Create(window)
world = World:Create() 
local camera = Camera:Create() 
camera:SetRotation(35,0,0) 
camera:Move(0,0,-3) 
local light = DirectionalLight:Create() 
light:SetRotation(35,35,0) 
        
--Create  model
model = Model:Box() 

--Create a material
local material = Material:Create() 
local surface = model:GetSurface(0) 
surface:SetMaterial(material) 
        
while true do        
        if window:Closed() or window:KeyHit(Key.Escape) then return false end

        model:Turn(0,Time:GetSpeed(),0) 

        --Get the model surface
        local surface = model:GetSurface(0) 
        
        --Get the surface material
        local material = surface:GetMaterial() 

        --Modify the material color
        local color = material:GetColor() 
        color.r = Math:Mod(color.r+Time:GetSpeed()*0.01,1) 
        color.g = Math:Mod(color.g+Time:GetSpeed()*0.012,1) 
        color.b = Math:Mod(color.b+Time:GetSpeed()*0.015,1) 
        material:SetColor(color) 

        Time:Update()
        world:Update()
        world:Render()
        context:Sync()
end
