Re: [pygame] split newbie strikes back

["Miguel Sicart" <mundial82@xxxxxxxxx>]

Hi,

Ethan, that was right on spot! Now I do feel like an idiot! (i was just drawing things in the wrong place, d'oh!)

About the physics code - it is the method I learned from Andy Harris' Game Programming book. I think it's a great book (it put me up to speed with pygame in about a month), but I guess it is a beginners book after all. 

So what should I do, a function that checks the boundaries? (and same goes for all the physics checking?)

thanks a bunch once again!

        playerTop.draw(screen)
        playerBot.draw(screen)
        topPoints.draw(screen)
        botPoints.draw(screen)

Try changing to:

playerTop.draw(top_screen)
playerBot.draw(bot_screen)
topPoints.draw(top_screen)
botPoints.draw(bot_screen)

etc.

Also, your check_bounds for the Square class doesn't make sense. The
purpose of using subsurfaces is that you don't have to worry about
"where" the sprite.rect is relative to the parent surface, only the
child surface. I changed that to this:

    def checkBounds(self):
        if self.rect.centerx > self.screen.get_width():
            self.rect.centerx = 0
        if self.rect.centerx < 0:
            self.rect.centerx = self.screen.get_width()
        if self.rect.centery > self.screen.get_height():
            self.rect.centery = 0
        if self.rect.centery < 0:
            self.rect.centery = self.screen.get_height()

I'd be a little wary of blending your sprite-drawing code and your
physics code like this, though.

Hope this helps!
