cocos2d-x JS 纯代码加载播放plist与png动画

 var cache = cc.spriteFrameCache;
 cache.addSpriteFrames(plist, png);

 var frames = [];
 for (var i = 1; i < 40; i++) {
 var spriteFrame = cache.getSpriteFrame(String(i) + ".png");
 if (spriteFrame) {
 frames.push(spriteFrame);
 cache.removeSpriteFrameByName(String(i) + ".png");
 } else {
 break;
 }
 }

 var animation = cc.Animation.create(frames, duration / frames.length);
 var animate = cc.animate(animation);
