我从awayd3D开始，在4.0beta版本上没有找到解决方案，我可以向你求助。

我在互联网上做了很多研究，希望找到关于灯光使用的解释，但很少有与每个版本 3 相关的解释。

我意识到这个场景（http://goupix.com/test/）。您可以使用 WASD 键或箭头键来移动。

为了实现这个场景，我有几个文件： Exploration.as：创建场景、相机和灯光。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：使用为我的装饰生成的表 ClassGenerateobjet.as：由 ClassGeneratemap 调用并将元素放置在场景中

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

我真的不知道如何使用我放置的灯。我不知道这是否确实是一种正确的光。

我希望你能帮助我。谢谢

从 Away3d 的 GitHub 中提取示例会有所帮助。
