Question

在Flash / ActionScript2中，是否可以捕获mousemove，buttonup和down事件，但只能在一个MovieClip中捕获？

目前，我可以通过听众捕捉鼠标等，但仅适用于整个舞台...... 我需要为选择画一个矩形，然后按一个保存按钮。问题是我保存mousedown和up上的坐标，但是当我按下保存按钮时，它会保存按下保存按钮时的坐标...

我已经尝试了mc.onXY，但要么根本不听，要么听整个舞台......

编辑：按要求编码 mc.onMouseDown 应该 mcImageToCrop.onMouseDown 当mcImageToCrop不起作用时，我确实将它改回mc ......

以下是一种可能对您有用的方法：您可以为movieClip定义 onPress 和 onRelease 事件，而不是使用侦听器，如下所示：

import flash.geom.Point;// you'll need this if you want to store your coordinates as Point objects

var startPoint:Point = new Point();
var endPoint:Point = new Point(); 

myClip.onPress= function() {
    startPoint.x=this._xmouse; //gives x-coord relative to myClip...
    startPoint.y=this._ymouse; // ...for coords relative to stage, omit "this."
    trace("start: "+startPoint.toString());
}

myClip.onRelease= function() {
    endPoint.x=this._xmouse;
    endPoint.y=this._ymouse;
    trace("end: "+endPoint.toString());
}

myButton.onRelease= function() {
    trace("saved coordinates: "+startPoint.toString()+endPoint.toString());
}

注意

之间的区别

onMouseUp = function（）{}按下鼠标按钮时调用。（的任何地方）
onPress = function（）{}当用户在指针悬停在影片剪辑上时单击鼠标时调用。

Actionscript鼠标控件仅限于一个动画片段？
