right now, I'm working on a mod of the tutorial base game. My biggest change right now is the implementation of a way tougher boss monster every 30 seconds. As I already modded the base monsters to basically spawn randomly off screen and enter the screen from all directions (did so by writing 4 events which spawn monsters, one for each direction), I also want the boss to not be too predictable. What I was essentially trying to do was along the lines of:
X: Random(either on the left or the right of the screen)
Y: Random(either on top or below the screen)
so that I basically create a spawn zone around the screen. But I'm lacking the syntax to do so.
Any idea how to do that?
