Question

使用EaselJs 0.6.0，我试图使用stagemousedown和stagemousemove事件拖动我的舞台。但是，正确捕获鼠标按下事件时，似乎不会触发舞台鼠标移动事件。

var stage = new createjs.Stage("canvas");
createjs.Ticker.addEventListener("tick", tick);
stage.addEventListener("stagemousedown", startDrag);    

// Container to drag around
var dragContainer = new createjs.Container();
stage.addChild(dragContainer);

//..... add stuff onto the stage

// Drag
var offset = new createjs.Point();
function startDrag(event) {
    console.log('startDrag');
    offset.x = stage.mouseX - dragContainer.x;
    offset.y = stage.mouseY - dragContainer.y;
    event.addEventListener("stagemousemove", doDrag);   
}

function doDrag(event) {
    console.log('doDrag');   
    dragContainer.x = event.stageX - offset.x;
    dragContainer.y = event.stageY - offset.y;
}

// Update the stage
function tick(event) {
    stage.update();
}

Here's a Fiddle

未调用DoDrag。我做错了什么？

Easeljs没有解雇stagemousemove事件
