So just recently I jumped into Python and Pyglet since I have been
looking for a language that can prototype much faster then my usual
C++ and it seemed to fit my need perfectly. I am also quite new at
game development in general so try not to be to hard on me ;p.
Anyways my question is about a little project I am working on (A
little space shooter) and I have having trouble trying to figure out a
good system to use for managing each objects state.
For example here is a snippet of code from my player class
http://pastebin.com/cBBkmVwA . Notice the big if/elif/else combination
I am using to update the player sprite based on keyboard input. This
seems rather ugly to me and a lot of work to maintain (Specially since
that code is only for basic movement of the sprite)... So I was
wondering is there a better way to do this? Or is this the correct way
to go about it?
I have been reading up on different state handling designs like FSM,
HFSM and Behavior Tress but I couldn't really find any code examples
of how they are implemented (I learn better by examining actual code).
So any help would be appreciated thank you.
I think the big 'if' statement is pretty standard practice although you
seem to be repeating tests e.g.
if self.keyHandler[key.UP]:
# UP-RIGHT
if self.keyHandler[key.UP] and self.keyHandler[key.RIGHT]:
self.image = resources.playerForwardRight
you test self.keyHandler[key.UP] and then if it is set you do it again.
