javascript - Easeljs Tweenlite 绕中心旋转

Question

我正在尝试获取 shape使用 TweenLite 围绕其中心旋转对象但它围绕其 x 旋转& y 。看起来像 transformOrigin的TweenLite不管用。我对 EaselJS 还是个新手和TweenLite .

请参阅this jsFiddle或者看一下下面的代码片段:

代码片段:

var canvas = document.getElementById('mainCanvas');
var stage = new createjs.Stage(canvas);

var shape = new createjs.Shape();
shape.graphics.beginFill('#000');
shape.graphics.drawRect(0, 0, 220, 220);
shape.graphics.endFill();
shape.x = 220;
shape.y = 220;
stage.addChild(shape);
stage.update();
//TweenLite.ticker.setFPS(40);
TweenLite.ticker.addEventListener('tick', stage.update, stage);

TweenLite.to(shape, 1, {
    repeat: -1,
    rotation: 360,
    transformOrigin: '50% 50%'
});

您可以设置regX和regY来围绕其中心变换某些东西，检查更新的jsfiddle:http://jsfiddle.net/n0kyvh1j/3/
