Why team num >= 7 is not allowed in Real-time Interaction mode?

[SimZhou]

Hey, I set --team-num 7 and it give me the following error:

Traceback (most recent call last):
  File "/home/zhou/miniconda3/envs/gobigger/lib/python3.6/runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)

    pygame.draw.circle(screen, PLAYER_COLORS[int(ball.team_name)][0], ball.position, ball.radius)
IndexError: list index out of range

and it works fine with team num smaller than 7, what's wrong?

Thanks for your issue.

In GoBigger, we apply color for different teams and unfortunately we only define 6 kinds of color here. We will add more colors to avoid this issue in the following version.

@SimZhou hi, we add more colors for up to 16 team in the game. You can check more details here.
