问: 动作, 动画, 以及骨骼动画是基于帧还是时间?

是基于update(dt) 这个dt, 还是基于update本身? 如果动画与dt关联, 那么就不能实现帧同步.

:rage: 全部无法用… 自己写个简版吧;

`proto.update = function (delta) {
// calculate delay time

if (this._delayTime > 0) {
    this._delayTime -= delta;
    if (this._delayTime > 0) {    动画有dt因子参与;
        // still waiting
        return;
       
}

// make first frame perfect

//var playPerfectFirstFrame = (this.time === 0);
if (this._currentFramePlayed) {
    this.time += (delta * this.speed);
}
else {
    this._currentFramePlayed = true;
}

this._process();

};`

    dt = this._computeEaseTime(dt);
    this.target.skewX = this._startSkewX + this._deltaX * dt;
    this.target.skewY = this._startSkewY + this._deltaY * dt; // 动作有DT
