For some reason my enemies (baddies) are not spawning in, i got all the baddie code from another program called "dodger" so i don't know why it's not working. It works when i tried it in dodger obviously but when i put it in my code nothing happens. My code still runs but when you're playing no baddies will fall from the sky like it's supposed to. There are other modules for this code but i didn't add them.

Answer 1

There are several issues with your code, but your current problem is that you create a new list of baddies every iteration of your main loop:

...
while not done:
    baddieAddCounter = 0
    baddies = []
    score += 1
    fact = ""
    ...

You should move baddies = [] outside the while loop.

You already seem to use sprites and groups, so I don't know why do you use dicts for your baddies instead of sprites.
