urho3d場景編輯設計的幾個點

1. 場景
2. 燈光
3. 設計相機
4. 場景zone
5. 其他

有一些需要注意的
zone這個需要注意的是

這一些引數
因為範圍和環境光沒設好，場景就是灰色的到是就悲劇了

下來就是編輯一個場景，我這裡的一個例子

base_scene.xml這個檔案如下

可以保持並在編輯器中載入進來看看
這個是一個簡單的場景

那麼如何載入這個檔案呢

function Start()
    graphics:SetWindowIcon(icon)
    graphics.windowTitle = "Urho3D Sample"
    
    local uiStyle = cache:GetResource("XMLFile", "UI/DefaultStyle.xml")
    if uiStyle == nil then
        return
    end

    engine:CreateConsole()
    console.defaultStyle = uiStyle
    console.background.opacity = 0.8
    engine:CreateDebugHud()
    debugHud.defaultStyle = uiStyle
    input.mouseVisible = true

    scene_ = Scene()
    scene_:LoadXML("Data/Scenes/base_scene.xml");

    local CamNode  = scene_:GetChild("CamNode");
    local camera = CamNode:GetComponent("Camera");

    camera.farClip = 300.0
    renderer:SetViewport(0, Viewport:new(scene_, camera))
end

function Stop()

end



 

大體這樣，需要具體的細節，要自己去嘗試了
