Update 07
Quick devlog tonight - it's beginning to come together!
The string setup works! I now have a simple way to make target shapes for each enemy. That lets me make fun shapes like this Pac-Man ghost shape for the ghost enemy. I think it's probably easily extendable? I hope it is!
Getting the game to count how much of the shape is filled was the hard part, and the code that does it is a total mess of if conditions which has to read object names rather than what type of object it is. It works, though!
Also I tried drawing a little window for the enemy to appear in, but the more I look at it, the less I like it. It doesn't gel with the rest of the game. Oh well.
