Here we go:
1. Open a new Flash file and save it as testDragable.fla
2. Draw a circle and convert it into a symbol
In the 'Convert to Symbol' dialogue
- Behavior: MovieClip
- Registration Point top-left
- toggle 'Export for ActionScript'
- Linkage Identifier: circle
and now comes the important part -
- AS 2.0 class : Dragable
In this example we'll save the .as file in the same folder as
testDraggable.fla,
usually you would save it in you classes folder. If your class path points
to
a folder named classes, and this folder has several sub-folders than the
class
name might look something like
com.motiondraw.movieclip.Draggable
3. make a MovieClip button, instance name button_mc
4. on the first frame of _root put this code:
button_mc.onRelease = function(){
initObj = new Object();
for(i=0;i<5; i++){
initObj._x = Math.random() * Stage.width;
initObj._y = Math.random() * Stage.height;
this._parent.attachMovie('circle', 'circle'+i+'_mc',i, initObj);
}
}
5. Open a new .as file and save it as Dragable.as in the same folder as
testDragable.fla
6. Code in Dragable.as:
class Dragable extends MovieClip{
// empty constructor
public function Dragable(){};
public function onPress(){this.startDrag();}
public function onRelease(){this.stopDrag();}
public function onReleaseOutside(){ this.stopDrag();}
}
7. Save, test and enjoy!
