How do I add a new enemy every 5 seconds in Pygame
Question:
I am currently creating a top-down shooter game in pygame and need a new enemy to spawn every 5 seconds. I am fairly new to coding and have looked at a few different tutorials but none of which have helped me. Here is a bit of my code. If you need to look at the whole code just ask me.
Thanks!

Answers:
You have a main loop. Before your loop, do:
enemytime = time.time() + 5
Then, in the loop, do something like:
if time.time() >= enemytime:
# Time to spawn a new enemy.
enemies.append( Enemy3( 100, 500 ) )
# Reset the alarm.
enemytime = time.time() + 5
