Hello,
I'm working on a text base space game, just for fun, and I've made a lot of progress. The problem I'm having right now is that sometimes, the psuedo-random is calculated out of its modulus. The way it works, as you can see in the code is that a random number is seeded based on the enemy's stats (like they can attack up to 50,40, etc), then that number is subtracted from a random location on the ship (hull, engine, etc.) However, at random times, I get stuff in the output that says like: "Your hull now has -2708998 health left." Is this a problem with the random function or is it a problem with my code? Thanks much!
