I added one extra monster to the room. So there are now two walking around, bumping into things, however I had found that the game would slow to a crawl if I had them both moving at the same time. After a lot of messing around and thinking about how to handle this I had decided maybe to make them take turns from walking and standing in place. So when Monster 1 is walking around randomly, Monster 2 is standing still and vice versa. This works and brought the speed back. Admittedly it’s a solution, but maybe not the “best” solution. I need to think of a better way if I want to also have more than two monsters in a room. I thought maybe to make it a bit more challenging, I could have the monsters shoot at the player while they are not moving around. I don’t know, we’ll see. I would really like it if all monsters in the room were walking around at all times.
