不提供全局坐标时如何修复 localToGlobal？

Question

我动态创建了 5 个在舞台上彼此相邻堆叠的盒子。第一个位于 (0,0)，下一个位于 (100,0)，第三个位于 (200,0)，依此类推。

问题我遇到的是，每次我单击每个单独的框时，它都会跟踪它位于 (0,0)。我尝试使用localToGlobal，但无济于事。

这是我尝试过的：
我尝试将事件侦听器附加到每个框，以便获取本地坐标并获取它们的全局等价物，但失败了。

import com.mahmoud.util.drawLabel;
import flash.geom.Point;
import flash.events.MouseEvent;

var d: drawLabel;
var global: Point;



for (var i: uint = 0; i < 5; i++) {
    d = new drawLabel();
    d.init(i, "", "", 100, 75, i * 101, 0);
    d.addEventListener(MouseEvent.CLICK, check);
    addChild(d);

 }


 function check(e: MouseEvent): void {
    global = new Point(drawLabel(e.currentTarget).x,drawLabel(e.currentTarget).y)
    trace(drawLabel(e.currentTarget).localToGlobal(global));

  }

更新：这就是 drawLabel 中的内容

您正在尝试 localToGlobal 您的 drawLabel 类，它位于 0,0。类内的盒子位于 100/200/300/等...您应该尝试在盒子上使用 localToGlobal，而不是类。或者您可以简单地移动班级并继续跟踪班级以简化事情。

绘制标签：

bc.graphics.drawRect(0, 0, labelWidth, labelHeight);
this.x = label_x;
this.y = label_y;

主要：

trace(e.currentTarget.x + ', ' + e.currentTarget.y);

---

如果出于任何原因您需要将 drawLabel 设置为 0,0 并将框移到其中，只需执行此操作即可。

绘制标签：

public var bc: Sprite;

主要：

trace(e.currentTarget.bc.x + ', ' + e.currentTarget.bc.y);

我遇到的问题是每次我点击每个人 框，它跟踪它在 (0,0)。我尝试使用localToGlobal 但是 无济于事。

另一种选择（避免使用localToGlobal）是只使用target.x 和target.y。
这将允许您定位每个单独的框。

示例代码：

for (var i: uint = 0; i < 5; i++) 
{
    d = new drawLabel();
    d.init(i, "", "", 100, 75, i * 100, 0);
    d.name = "label_" + i; //# give each one a name if you want to...
    d.addEventListener(MouseEvent.CLICK, check);
    addChild(d);
 }

然后像这样检查...（注意：使用currentTarget 作为名称，然后使用target 作为x/y 作为位置）。

function check(e: MouseEvent): void 
{
    trace( " " + "\n" + "# Got checking click" + "\n" + "-----------------------");
    trace( "Name : " + e.currentTarget.name);
    trace( "Pos  : " + "{ x: " + e.target.x + ", y: " + e.target.y + " }" );
}
