Flax是基于flash的游戏制作工具，所以flash里所见即游戏中所得，场景编辑尤其如此。

请看在线示例

相关代码：

var GameShooters = BaseScene.extend({
    onEnter:function()
    {
        this._super();
        flax.assetsManager.createDisplay(res.shooters, "level1",{parent:this});
    }
})

var thePropNames = ["HealProp", "MultiProp", "SpeedProp", "ArmorProp"];

var BattleStage = flax.MovieClip.extend({
    enemies:null,
    props:null,
    onEnter:function()
    {
        this._super();
        //Init the global bullet container(SpriteBatchNode)
        flax.BulletCanvas.create(res.shooters, this);
        this.initElements();
        //Set the enemies as the player's target
        //TODO, there is another method with TileMap to check the bullet collision in Flax
        this.player.targets = this.enemies;
        this.player.props = this.props;
        //Scrolling background
//        var bg = new flax.ScrollingBG(this.bg);
//        bg.startYScroll(-50);
    },
    initElements:function()
    {
        this.enemies = [];
        this.props = [];
        for(var i = 0; i < this.getChildrenCount(); i++){             
            var child = this.children[i];             
            if(child instanceof Enemy){                 
                 this.enemies.push(child);             
            }else if(thePropNames.indexOf(child.assetID) > -1){
                this.props.push(child);
            }
        }
    }
    ...
})
