Hi,

I've looked up the AS2 Heat seeking missile example, but it doesn't work for my game. The position parameters are the target. This game is also a fully scrollable terrain jet fighter game. The Missile doesn't rotate in the correct direction, doesn't turn towards the target, for example if the target is behind the missile.

Code:
public function setGuidance(index:Number,posx:Number,posy:Number, rate:Number):void{
			var it=index;
			var disX = 0;
			var disY = 0;
			var disTot = 0;
			var turnRate = rate;
			var moveX = 0;
			var moveY = 0;
			var totalMov = 0;
			var rot = 0;
			var moveTot = 0;
			
				
				if(this.missiles[it].launched && this.missiles[it].guidance){
					
					disX =  posx - (this.missiles[it].object as Bitmap).x;
					disY =  posy - (this.missiles[it].object as Bitmap).y;
					disTot = Math.sqrt(disX*disX + disY*disY);
					
					if(disTot <= 1000){
						
						rot = (this.missiles[it].object as Bitmap).rotation;
						moveX = turnRate * (disX / disTot);
						moveY = turnRate * (disY / disTot);
						moveTot = Math.sqrt(moveX*moveX + moveY*moveY);
						
						this.missiles[it].xspeed+=moveX;
						this.missiles[it].yspeed+=moveY;
						
						
						moveX = this.missiles[it].xspeed*moveX / moveTot;
						moveY = this.missiles[it].yspeed*moveY / moveTot;
						
						(this.missiles[it].object as Bitmap).x += moveX;
						(this.missiles[it].object as Bitmap).y += moveY;
						
						(this.missiles[it].object as Bitmap).rotation =180*Math.atan2(moveY, moveX) / Math.PI;
						
						
					}
				}
