I know, its sad; having trouble drawing lines. Anyway, I have two movieclips that travel around the stage, and my goal is to draw the triangle the vectors form dynamically. However, when I draw these lines, they keep drawing over and over, and I want the lines to be redrawn each frame…clearing the old line.

When I use the clear(); function, no lines show up at all…here’s my code, any help?

```auto
drawLines = function() {
 	_root.createEmptyMovieClip("aLine",3);
 	_root.createEmptyMovieClip("bLine",4);
 	_root.createEmptyMovieClip("cLine",5);
 	
 	aLine.lineStyle(2,0xFF0000,100);
 	bLine.lineStyle(2,0x0000FF,100);
 	cLine.lineStyle(2,0xFFFF00,100);
 	
 	this.onEnterFrame = function() {
 		aLine.moveTo(ball1._x,ball1._y);
 		aLine.lineTo(ball2._x,ball1._y);
 		
 		Line.moveTo(ball2._x,ball2._y);
 		bLine.lineTo(ball2._x,ball1._y);
 		
 		cLine.moveTo(ball1._x,ball1._y);
 		cLine.lineTo(ball2._x,ball2._y);
 		
 		aLine.clear();
 		bLine.clear();
 		cLine.clear();
 	}
 }

```

This is the code for just the function which draws the lines.
