actionscript-3 - AS3 > 鼠标事件没有发生？

Question

背景:试图让一个球出现在鼠标所在的相同位置。使用 Box2D 库。处理类文件 (.as)

问题:鼠标事件不起作用(我点击但没有任何反应)。没有任何输出错误。 :(

鼠标事件 编辑:Marty Wallace 更正了我的代码，但鼠标事件仍然不起作用。

   private function _clicked(e:MouseEvent)
            {
                sim.addCircle({x:mouseX, y:mouseY, radius:0.25, density:5});
                sim.start();  

完整代码:

package  {

    import flash.display.MovieClip;
    import com.actionsnippet.qbox.*;  
    import flash.events.MouseEvent;

    [SWF(width = 350, height = 600, frameRate = 60)]  

    public class MouseTest extends MovieClip {

        public var sim:QuickBox2D;

        /**
         * Constructor
         */
        public function MouseTest()
        {
            sim = new QuickBox2D(this);  
            sim.createStageWalls();

            addEventListener(MouseEvent.CLICK, _clicked);
        }

        /**
         * ..
         * @param e MouseEvent.CLICK
         */
        private function _clicked(e:MouseEvent)
        {
            sim.addCircle({x:mouseX, y:mouseY, radius:0.25, density:5});
            sim.start();  

        }
    }

}

由 Gabriel Meono 编辑:

QuickBOX2D uses meters instead of pixels. To work with pixels with this library, one must divide each number by 30. I simply added a "/3" to the mouseX / mouseY and it worked! I updated your code, thanks!

要么这样做(推荐):

public var sim:QuickBox2D;

/**
 * Constructor
 */
public function MouseTest()
{
    sim = new QuickBox2D(this);  
    sim.createStageWalls();

    addEventListener(MouseEvent.CLICK, _clicked);
}

/**
 * ..
 * @param e MouseEvent.CLICK
 */
private function _clicked(e:MouseEvent)
{
    sim.addCircle({x:(mouseX/30), y:(mouseY/30), density:5});
    sim.start();  
}

或者这个(不那么推荐，但更接近你的代码):

/**
 * Constructor
 */
public function MouseTest()
{
    var sim:QuickBox2D = new QuickBox2D(this);  
    sim.createStageWalls();

    addEventListener(
        MouseEvent.CLICK,
        function(e:MouseEvent):void
        {
            sim.addCircle({x:(mouseX/30), y:(mouseY/30), radius:0.25, density:5});
            sim.start();
        }
    );
}
