HI all, im needing help, im in flash as2 and im trying to make my enemys move diagonally downwards and when they reach the limits iv set (the buildings) i want them to bounce off and go the other way, but the way its going one it hits the sides, they just go down straight. i couldnt get it to work with hittests so iv just used > < limits. code as follows:

onClipEvent (enterFrame) {
 enemySpeed = 2;
 sideSpeed = 4;
  
  if (this.hitTest(_root.newBullet)) {
  this.gotoAndStop("dead");
  } 
 this._y += enemySpeed;
 this._x -= sideSpeed;
 
 if (this._x<175) {
  this._x += sideSpeed;
 }
 if (this._x>375) {
  this._x -= sideSpeed;
 }
}

Notice from rvalkass:

Please remember to put code inside Code tags.

I don't know how much help you can get with that little information...

So, you want your enemy to bounce off when hitting a wall, right?

What exactly is sideSpeed? The movement of your stage, or something similar?

Basically, if you want your enemy to bounce off in the opposite direction - you need to set its x and y values to increment for minus speed. So, for instance, you would go for this:

this._x += -speed;
this._y += -speed;

As a basic rule of thumb.
