1.新增粒子庫，放在專案同級目錄下（必須！！必須！！）

2.新增路徑：
3.新增程式碼：

private creatParticle(_pname: string, _target, _x: number, _y: number)
 {
    if (_target != null) 
    {
        let texture = RES.getRes(_pname + "_png");
        let config = RES.getRes(_pname + "_json");

        var _particle = new particle.GravityParticleSystem(texture, config);
        _particle.touchEnabled = false;
        _target.addChild(_particle);

        _particle.x = _x;
        _particle.y = _y;
        _particle.start()
        return _particle;
    } 
    else
     {
        console.log("裝載容器不存在");
    }
}
