I'm building a top-down shooter. I have a target-A which basically sits in the center of the room I have ships which fly around the room in various formation patterns or whatever. The ships have laserbeams that fire directly forward. I want the ships, as they fly about the room - to check whether they are facing target-A - and if so - shoot their lasers. I have everything figured out - EXCEPT - how to check if an instance is facing another instance. I've tried: if direction = point_angle ( x, y, target.x, target.y ) I've tried: if image_angle = point_angle ( x, y, target.x, target.y ) But I'm missing something or using it wrong - I dunno. It runs fine and doesn't throw any errors that I can see. But it just doesn't pull the trigger when it's supposed to. My best guess - was that the two values are really never the same because of the rotation of the enemy ships. They rotate at a specific rate per frame which likely makes the two sides of the equation basically impossible without a relative range in place. SO - My next attempt was something like IF direction - point_angle (x,y, target.x, target.y) <= 20 But nope... that didn't do diddly either. So now i'm sad. *sigh* Any ideas or insight would be great. I'm using DND - but I'm not afraid to write complex expressions.
