Fix hanging bug caused by uninitialized variables

The game would sometimes appear to init and just hang, not processing
any new input. This would only happen some of the time. Digging revealed
crazy values for the vector lengths and angles.

Of course! They were never initialized. Moving the initialization to
functions will help prevent this.
