Hello all,
I created a simple game using the pygame and livewires packages a few years ago on a windows PC. Since then my pc died on me :( and I've switched over to a mac. I decided I wanted to dust off my old game, make some modifications, and post it to a personal site I'm working on. Here are my specs on my mac:
Python Version 2.6
Pygame 1.9.2
Livewires 2.1
However, when I fire up my game using the python launcher or idle I get the following error:
games.init(screen_width = 700, screen_height = 700, fps = 50)
AttributeError: 'module' object has no attribute 'init'
I know this code used to work but there have been many updates for python since I last used it and I'll bet there is different syntax for what I'm trying to do. I've searched for related topics and found 2 individuals with the same error but whose questions didn't get solved. Anyways, here is the code:
# Deep Space
# A ship must shoot hammers to destroy and evil, slime throwing, space duck.

Thanks in advance for any help that's thrown my way!
