I'm not totally sure, but what I would try to do is, make it so when your player is on the same y value as your enemies, make them "shoot".... so just use game.position.y of your main character or whatever it is good luck! Oh and you'll probably have to create an attribute that holds your main characters y value

You need to keep track of the Main Player's X and Y values.

Create two global game attributes (real) called PlayerX and PlayerY.

In the main player actor, constrain these two global game attributes to self.Position.X and self.Position.Y, like this:

Constrain Attribute
game.PlayerX To: self.Position.X

Constrain Attribute
game.PlayerY To: self.Position.Y

Now the enemies can keep track of where the Main Player is by using the magnitude function. They can react if the Main Player is, say, 200 pixels away from them. Like this:

In the Enemy Actor, create a real attribute called MyDistanceFromPlayer.
Constrain the Attribute like this:

Constrain Attribute
self.MyDistanceFromPlayer To: magnitude(abs(game.PlayerX-self.Position.X),abs(game.PlayerY-self.Position.Y))

Then create a Rule:

Rule
When self.MyDistanceFromPlayer < 200
[Attack the Player]

Hope this helps!
