Re: [pygame] Help Starting/doing The Main Code
I'd suggest making a clone of pong, and asteroids and maybe missile command. (They will be easier to write than a shooting platformer, and be more gradual that jumping right into too much at once ) Your main loop looks something like this: class Game(): """game logic class""" def __init__(self, width=1024, height=768): # ... snipped def loop(self): """main game loop""" self.bDone = false while not self.bDone: # handle events, physics/updates, and render self.handle_events() self.update() self.draw() def handle_events(self): """input""" for event in pygame.event.get(): if event.type == pygame.QUIT: sys.exit() # event: keydown elif event.type == KEYDOWN: # exit on 'escape' if (event.key == K_ESCAPE): self.bDone = True def draw(self): """render screen""" # clear screen self.screen.fill( pygame.color.Color("black") ) # render sprites # flip pygame.display.flip() def update(self): """update units, check for collisions(if needed), etc...""" # ... snipped ... -- Jake
Re: [pygame] Window move oddity
Indeed. That's what it does. You should be able to put a maximum elapsed time for your frames. That handles the moving window thing, and also if there's some other pause from the OS. Like if firefox plays a flash animation in the background that uses up heaps of cpu blocking your program for a while. cu.

Re: [pygame] Window move oddity
Well, immediately after posting I figured it out. ;) Moving the window causes the program to pause and thus when it comes back the delta time difference between frames spikes. And then my screwy collision detection teleports the character much further than should be possible. In certain situations, moving the game window (800x600) on the Windows desktop sometimes causes the main character to teleport upwards on screen to the next available platform.
[pygame] Window move oddity
I'm currently working on a simple platform game engine using Python 2.5.2 win32 and Pygame 1.8.1. The main character's location is defined by x and y floats. The levels are stored in a tree format to allow for vast open spaces. Nothing ground-breaking. I've been working on the collision system. In certain situations, moving the game window (800x600) on the Windows desktop sometimes causes the main character to teleport upwards on screen to the next available platform. Does anyone know if moving the pygame display window sends some kind of event to Pygame? Printing all events in pygame.event.get() reveals no event occurring when the window moves and the character teleports. It doesn't always happen, but when it does it doesn't matter if I move the window 1 pixel or across the desktop. Where the character teleports and how is obviously because of my screwy unfinished collision detection, because if I comment out the collision detection calls the oddity doesn't appear. But I just wondered if anyone knows why moving the window would trigger anything? Aaron
