如何使用away3d 4.0 Beta中的多個燈光？

Question

我從awayd3D開始，並沒有找到一個版本4.0beta的解決方案，我可以呼籲你。

我已經做了許多研究互聯網，希望能找到使用燈光的解釋，而是與每個版本3.

我意識到了這一幕一些解釋（http://goupix.com/test上/）。您可以使用WASD鍵或箭頭鍵移動。

爲了實現這一幕，我有幾個文件： Exploration.as：創建現場，攝像頭和光線。 光：

PointLight light = new(); 
light.x = -2000; 
light.y = 1000; 
light.z = -1000; 
light.color 0xffeeaa =// Here, select the new color of the light source 
view.scene.addChild (light); 

ClassGeneratemap.as：用來裝飾我 ClassGenerateobjet.as生成的表格：由ClassGeneratemap調用和地點的元素在場景

public function onAssetComplete(event:AssetEvent):void { 
    if (event.asset.assetType == AssetType.MESH && event.asset.assetNamespace == token) { 
     AssetLibrary.removeEventListener(AssetEvent.ASSET_COMPLETE, onAssetComplete);    
     trace("position : " + posX + " : " + posY); 
     mesh = event.asset as Mesh; 
     mesh.geometry.scale(1); 
     mesh.x = -posX * instData.scale; 
     mesh.z = posY * instData.scale; 
     mesh.castsShadows = true ; 
     //trace("position : " + mesh.x + " : " + mesh.z); 
     instExploration.scene.addChild(mesh); 
    }//End If 
}//End onAssetComplete 

我實在看不出如何使用我放置的燈。我不知道這是否是正確的光。

我希望你能幫助我。 謝謝你從Away3D中的GitHub的

拉例子會有所幫助。
