cocos2d-js创建帧动画

//方式一，通过多张图片来创建
this.dragon = new cc.Sprite("res/player_animation/action1.png");
this.dragon.setPosition(cc.p(cc.winSize.width*0.3, cc.winSize.height/2));
this.addChild(this.dragon);

//创建帧动画序列，名词形式
var animation = new cc.Animation();
for (var i = 1; i <= 4; i++)
{
animation.addSpriteFrameWithFile("res/player_animation/action"+ i +".png");
}
//设置帧动画属性
animation.setDelayPerUnit(2.0 / 4);       //每一帧停留的时间
animation.setRestoreOriginalFrame(true);   //播放完后回到第一帧
var animate = new cc.Animate(animation);
this.dragon.runAction(new cc.RepeatForever(animate));
