Making an enemy follow the player

programming flash
1

I’ve been working on a game for my AS3 class that involves enemies randomly spawning from all direction and following the player in an attempt to collide with him. I can get the enemies to spawn from one direction as well as move in a single direction but I can’t get the spawning from all sides or the following the player around to work.

 I've been at this for a couple of weeks now and followed several suggestions and tutorials (including one from here) with no success and this thing is due by tonight :worried:. Here's the code from my enemy class. All of the code of the game is done through AS files with no coding done within movie clips or on the timeline.

package
{

import flash.display.MovieClip;
import flash.display.Stage;
import flash.events.Event;

public class Enemy extends MovieClip
{
    
    private var stageRef:Stage;
    private var vy:Number = 3;
    private var ay:Number = .4;
    private var target:Tank;
    
    public function Enemy(stageRef:Stage, target:Tank) : void
    {
        this.stageRef = stageRef;
        this.target = target;
        
        x = Math.random() * stageRef.stageWidth;
        y = -5;
        
        addEventListener(Event.ENTER_FRAME, loop, false, 0, true);
    }
    
    private function loop(e:Event) : void 
    {
        
        
    
        vy += ay;
        y += vy;
        
        if (y > stageRef.stageHeight)
            removeSelf();
            
        //if (y - 15 < target.y && y + 15 > target.y)
            //fireWeapon();
    }
    
    /*private function fireWeapon() : void
    {
        stageRef.addChild(new EnemyBullet(stageRef, target, x, y, -5));
        stageRef.addChild(new EnemyBullet(stageRef, target, x, y, 5));
    }*/
    

    
    private function removeSelf() : void {
        
        removeEventListener(Event.ENTER_FRAME, loop);
        
        if (stageRef.contains(this))
            stageRef.removeChild(this);
        
    }
    
}

}
