Bone:SetScale

This method can be used to manually scale a bone. You can control skinned models enirely in code or apply your own movements on top of animation.

Syntax

• SetScale(number scale)

Remarks

To combine programmatic movement with animation, this method should be called after World::Update and before World::Render.

Example

This example will load and display an animated model, but we will add code to give the character a supersized noggin.

function main()
    -- Get the displays
    local displays = ultraengine.GetDisplays()

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

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

    -- Create a world
    local world = ultraengine.CreateWorld()

    -- Create a camera
    local camera = ultraengine.CreateCamera(world)
    camera:SetClearColor(0.125)
    camera:SetFov(70)
    camera:Move(0, 2, -8)

    -- Create light
    local light = ultraengine.CreateBoxLight(world)
    light:SetRotation(45, 35, 0)
    light:SetRange(-10, 10)

    -- Load FreeImage plugin
    local plugin = ultraengine.LoadPlugin("Plugins/FITextureLoader")

    -- Model by PixelMannen
    -- https://opengameart.org/content/fox-and-shiba
    local model = ultraengine.LoadModel(world, "https://github.com/UltraEngine/Documentation/raw/master/Assets/Models/Characters/Fox.glb")
    model:SetScale(0.05)
    model:Animate(1)
    model:SetRotation(0, -90, 0)

    local neck = model.skeleton:FindBone("b_Neck_04")
    local rotation = ultraengine.Vec3()

    -- Main loop
    while (window:Closed() == false)
    do
        world:Update()

        rotation.y = ultraengine.Cos(ultraengine.Millisecs() / 10.0) * 65.0
        neck:SetRotation(rotation)
        neck:SetScale(2)

        world:Render(framebuffer)
    end
end

main()
