[]生成的粒子特效怎么设置colorComponentInter无效？

    function UILetterBox(letter, width) {

        UILetterBox.super(this);



        letter = letter;

        this.loadImage('res/jiezou/wenzi2.png');



        Laya.loader.load("res/parts/qipao.part", Handler.create(this, onAssetsLoaded), null, Loader.JSON);

    }



    function onAssetsLoaded(settings) {

        settings.colorComponentInter = true;

        sp = new Particle2D(settings);

        sp.emitter.start();

        sp.play();

        sp.x = 90;

        sp.y = 55;

        this.addChild(sp);

    }
