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
