如果我传了大于 360 的数给 rotateTo，动作效果就不对了
看了下引擎实现
/*
* CCActionInterval.js
*/
startWithTarget:function (target) {
cc.ActionInterval.prototype.startWithTarget.call(this, target);
// Calculate X
var locStartAngleX = target.rotationX % 360.0;
var locDiffAngleX = this._dstAngleX - locStartAngleX;
if (locDiffAngleX > 180)
locDiffAngleX -= 360;
if (locDiffAngleX < -180)
locDiffAngleX += 360;
this._startAngleX = locStartAngleX;
this._diffAngleX = locDiffAngleX;
// Calculate Y It's duplicated from calculating X since the rotation wrap should be the same
this._startAngleY = target.rotationY % 360.0;
var locDiffAngleY = this._dstAngleY - this._startAngleY;
if (locDiffAngleY > 180)
locDiffAngleY -= 360;
if (locDiffAngleY < -180)
locDiffAngleY += 360;
this._diffAngleY = locDiffAngleY;
},
那个 locDiffAngleX 是不是也应该 % 360.0
