Okay, here's the deal:
dradstr is the player character
lobulletright and lobulletleft are the projectiles
The code is:

CODE

{
if dradstr.y > self.y - 5 and dradstr.y < self.y + 5
{
if dradstr.x > self.x
instance_create(self.x,self.y,lobulletright)
if dradstr.x < self.x
instance_create(self.x,self.y,lobulletleft)
}
}

Now this is fine, but it would be nicer if the enemy only fired when you were at most 150 pixels away. Is there a way I can make the game find the distance between these two objects?

Place this first:

If distance_to_object(dradstr) is smaller than 150

...but only if you have a turret object.

Are you talking about an older version of GM?

The function is point_distance(x1,y1,x2,y2) in GM6.
