在Actionscript上播放声音

我有一个简单的拖放游戏，开始时是Flash，并且大多数情况下都能正常工作.

I have a simple drag and drop game started in flash and mostly working.

我添加了我的动物，您可以将它们拖放到正确的位置.我还添加了声音，以便当将动物放置在正确的位置时，这是可行的，但是每次我向该动物中添加新的动物时它会播放该声音以及最后一个动物的声音.

I have added my animals and you can drag and drop them in the right place.I have also added sound so that when the animal is dropped in the right spot , that is working however each time I add a new animal to the right spot it plays that sound and the last animal sound as well.

例如.将猪放到猪的空间里，播放猪的声音 将牛放在牛的空间中，播放牛声和猪声 将鸭子放到鸭子空间中，播放鸭子声，牛声和猪声.

e.g. place pig in pig space , it plays pig sound place cow in cow space , it plays cow sound and pig sound place duck in duck space , it plays duck sound and cow sound and pig sound.

很明显，我只想在将动物放置在正确的位置时播放声音-放下(也不要放下一只动物)

Obviously I only want to play the sound when the animal is placed in the right place - on drop ( not on next animal drop also )

我不确定自己做错了什么

I'm not sure what I have done wrong

推荐答案

查看您的MouseUp事件处理程序.

Look at your MouseUp event handlers.

您正在将事件侦听器添加到舞台上.因此，每当舞台听到鼠标上移事件时，它们都会被调用.

You are adding the event listener to the stage. So they are all getting called whenever the stage hears a mouse up event.

将这些侦听器添加到母牛，猪等中，就像对鼠标侦听器所做的一样.

Add those listeners to the cow, pig etc just as you did for the mouse down listeners.

那应该解决.

Pig.addEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag); function fl_ClickToDrag(event:MouseEvent):void { Pig.startDrag(); } //stage.addEventListener(MouseEvent.MOUSE_UP, fl_ReleaseToDrop); // change to this Pig.addEventListener(MouseEvent.MOUSE_UP, fl_ReleaseToDrop);
