Time for action – creating and using a key map

1. The first step to using a key map is to actually create the dictionary that serves the purpose. Right after the line that calls self.cycle.setPos() method in the __init__ method, insert the following block of code to create the dictionary:

       self.keyMap = {"w" : False,
               "s" : False,
               "a" : False,
               "d" : False}

2. Now we need to register events for the four keys in our key map. Replace the current self.accept() call, with the following code:

       self.accept("w", self.setKey, ["w", True])
       self.accept("s", self.setKey, ["s", True])
       self.accept("a", self.setKey, ["a", True])
       self.accept("d", self.setKey, ["d", True])
       self.accept("w-up", self.setKey, ["w", False])
       self.accept("s-up", self.setKey, ["s", False])
       self.accept("a-up", self.setKey, ["a", False])
       self.accept("d-up", self.setKey, ["d", False])

3. Next, we need to change our setKey() method to look like this:

   def setKey(self, key, value...
