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);
