< READ THIS > ---------------------------------------- THIS IS AMAZING! Or at least I think so. It is multiple entities (in this case bots that fight in an arena) with only 4 sprites! Technically there are 6 sprites but 1 just appears saying "winner" or "stalemate" when it's told to and the other does literally nothing. And it's scalable too! I just put in 8 different guys to keep it simple but you can have as many or as few as you want. And because they can each have their own health bars this engine is perfect for creating your own enemies. Feel free to use this code for your own projects, just give me credit.
There is currently no user input besides telling the simulation how many bots to put it. It will run the simulation and then when there is only one bot left show you the winner or if all of them died it will tell you a stalemate happened.
