Mesh:SetVertexColor

This method can be used to modify the color of a single vertex.

Syntax

• SetVertexColor(number index, number r, number g, number b, number a = 1)
• SetVertexColor(number index, Vec4 color)

Remarks

Vertex colors are not compatible with skinned meshes.

Example

-- Get the displays
local displays = GetDisplays()

-- Create a window
local window = CreateWindow("Ultra Engine", 0, 0, 1280, 720, displays[1], WINDOW_CENTER | WINDOW_TITLEBAR)

-- Create a world
local world = CreateWorld()

-- Create a framebuffer
local framebuffer = CreateFramebuffer(window)

-- Create a camera
local camera = CreateCamera(world)
camera:SetClearColor(0.125)
camera:SetPosition(0, 0, -1)

-- Create a light
local light = CreateBoxLight(world)
light:SetRotation(45, 35, 0)
light:SetRange(-10, 10)
light:SetColor(2)

-- Create a model
local model = CreateSphere(world)
for v = 1, model.lods[1].meshes[1]:CountVertices() do
    model.lods[1].meshes[1]:SetVertexColor(v, Random(), Random(), Random())
end

-- Main loop
while window:Closed() == false and window:KeyDown(KEY_ESCAPE) == false do
    model:Turn(0, 1, 0)
    world:Update()
    world:Render(framebuffer)
end
