urho3d场景编辑设计的几个点

场景
灯光
设计相机
场景zone
其他

有一些需要注意的
zone这个需要注意的是
关于urho3d编辑器场景编辑处理

这一些参数
因为范围和环境光没设好，场景就是灰色的到是就悲剧了

下来就是编辑一个场景，我这里的一个例子

base_scene.xml这个文件如下

可以保持并在编辑器中加载进来看看
这个是一个简单的场景

那么如何加载这个文件呢

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

大体这样，需要具体的细节，要自己去尝试了
