Question

I would leave to great a simple level system. When the score Variable reaches a certain number it would increase enemies (balls) & velocity(Speed) for example:

if score >= 500:
   enemies=6
   velocity=2

I have tried few methods, the my first attempt was like the above within my game loop but I wasn’t able to change it on the fly, Error:

Traceback (most recent call last):
 File "C:\Users\MO\Desktop\Twerk\ballbounce_changed.py", line 233, in <module>
  game()
File "C:\Users\MO\Desktop\Twerk\ballbounce_changed.py", line 182, in game
 positionx[i]=positionx[i]+positionxmove[i]
  IndexError: list index out of range

I have also tried other methods which didn’t work. can you please help me implement a level system. My game code can found here: http://pastebin.com/nhqKdR19

Thank you

Instead of:

if score == 500:
    enemies = 6
    velocity = 2

You should probably have an increase_difficulty() method that modifies your tracking lists and increases the velocity value. You should also be using >= instead of == as I mentioned above. Then your game loop code would be:

if score >= 500:
    increase_difficulty()
