hi, I'm a Python beginner with a basic question. I'm writing a game where I have keyboard input handling defined in one class, and command execution defined in another class. The keyboard handler class contains a dictionary that maps a key to a command string (like 'h': 'left') and the command handler class contains functions that do the commands (like def do_right(self):),
I create instances of these classes in a list attached to a third, 'brain' class. What I'd like to have happen is when the player presses a key, the command string is passed to the command handler, which runs the function. However I can't figure out a good way to make this happen. I've tried a dictionary mapping command strings to functions in the command handler class, but those dictionary values are evaluated just once when the class is instantiated. I can create a dictionary in a separate function in the command handler (like a do_command function) but creating what could be a big dictionary for each input seems kind of silly (unless I'm misunderstanding something there). What would be a good way to make this happen, or is there a different kind of architecture I should be thinking of? -- http://mail.python.org/mailman/listinfo/python-list
