创建3D场景

export default class Test extends Laya.Script {
    constructor() { 
        super(); 
 
        //搭建场景
        var scene3d = new Laya.Scene3D();
        Laya.stage.addChild(scene3d);
        //创建相机
        var camera = new Laya.Camera(0,0.3,100);
        camera.fieldOfView = 60;
        camera.clearColor = new Laya.Vector4(0,0,0,1);
        scene3d.addChild(camera);
        camera.transform.translate(new Laya.Vector3(0,1,0));
        camera.cullingMask = 1<<2;//层级
        //camera.removeAllLayers();
        //camera.addLayer(1);
        //camera.cullingMask = (1<<1)|(1<<2);
        //物体
        //几何网格/网格图元
        var cube = new Laya.MeshSprite3D(Laya.PrimitiveMesh.createBox(1,1,1));
        scene3d.addChild(cube);
        //位置
        cube.transform.translate(new Laya.Vector3(0,0,-10));
        //层级
        cube.layer = 2;
        //材质
        var m = new Laya.UnlitMaterial();
        //贴图
        Laya.Texture2D.load("res/background.png",Laya.Handler.create(this,function(tex){
