Playing sounds on Actionscript

Question

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

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.

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.

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 )

I'm not sure what I have done wrong

Answer 1

Look at your MouseUp event handlers.

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

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

That should solve it.

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);
