I'm making a game which uses procedurally generated levels, and when I'm testing I'll often want to reproduce a level. Right now I haven't made any way to save the levels, but I thought a simpler solution would be to just reuse the seed used by Python's random module. However I've tried using both random.seed() and random.setstate() and neither seem to reliably reproduce results. Oddly, I'll sometimes get the same level a few times in a row if I reuse a seed, but it's never completely 100% reliable. Should I just save the level normally (as a file containing its information)?
Edit:
Thanks for the help everyone. It turns out that my problem came from the fact that I was randomly selecting sprites from groups in Pygame, which are retrieved in unordered dictionary views. I altered my code to avoid using Pygame's sprite groups for that part and it works perfectly now.
At the point when you want another level, you should initially create another levelRandom object, and give that object to a level-generator to produce the level (if you are using one)
What's the easiest way to reproduce a randomly generated level in Python?
