2. Create 4 blank frames with “Frame” > “New” so you have “Frame 1″ to “Frame 5″ in the frame list.

Frame 1

1. Download from here the source file and extract trash images.
2. Import image “pieceofpaper.gif” (File > Import Image) and move it outside visible area.
3. Convert it to sprite (Edit > Convert to Sprite), name it “Garbage” and check “ActionScript” target (Item > Placement Properties)
4. Import image “opentrash.gif” and move it to X:170, Y:118 (Edit > Move To) .
5. Draw an ellipse over the hole of the trash. Set fill color to black, 1% opacity, no line
6. Convert it to sprite, name it “Hole” and check “ActionScript” target
7. Add the text “Put all papers into trash”
8. Add Frame ActionScript (Frame > ActionScript):

   maxpapers=1;
   

Frame 2

1. Add the text “GET READY!”
2. Set background to “Frame 1″

Frame 3

1. Set frame delay to “Stop”
2. Set background to “Frame 1″
3. Import “laser.wav” sound and set the frame sound
4. Add Frame ActionScript:

   maxpapers = maxpapers * 2; // at each run increase the number of pieces
   collected = 0; // count collected items
   
   function checkifallcollected()
   {
   	// check if all items are collected and go to congratulations frame
   	if(collected==maxpapers) gotoAndPlay("Frame 4");
   }
   
   // this array will hold all pieces
   var garbages = new Array();
   
   // create maxpapers pieces
   for(i=0;i<maxpapers;i++)
   {
   	// create new instance of the paper
   	garbage[i] = Garbage.duplicateMovieClip("garbage"+i,100+i); 
   
   	// put it in random place and random rotation
   	garbage[i]._x = 30+100*Math.random();
   	garbage[i]._y = 30+200*Math.random();
   	garbage[i]._rotation = 360*Math.random();	
   
   	// define mouse events
   	garbage[i].onPress=function() { this.startDrag();};
   	garbage[i].onRelease=function()
   		{
   			// check if this piece hits the hole
   			if(this._droptarget=="/Hole") {this.removeMovieClip();collected++;}
   
   			stopDrag();
   			checkifallcollected();
   		};
