[pygame] spritecollide-problem

[Sven Dehmlow <sven@xxxxxxxxxxxxxxxx>]

Hi,
I'm writing a soccer game with pygame. Currently I'm stuck with an error 
caused by  pygame.sprite.spritecollide.

The error message is:
 File "/usr/lib/python2.5/site-packages/pygame/sprite.py", line 482, in 
spritecollide
   spritecollide = sprite.rect.colliderect
AttributeError: 'list' object has no attribute 'colliderect'

It's thrown in a collision-detection function in the player class:

          for border in pygame.sprite.spritecollide(self, borders, False):
               direction = border.reflect()

The constructor of the player class goes like this ...

class Player(pygame.sprite.Sprite):      
       def __init__(self, side, pos, spritesheet, sprites_up,
                     sprites_down, sprites_left, sprites_right):
               pygame.sprite.Sprite.__init__(self)
              
               spritesheet = sprites.Sprites(spritesheet)

               self.images_up = spritesheet.imgsat(sprites_up, -1)
              
               self.images_right = spritesheet.imgsat(sprites_right, -1)

               self.images_down = spritesheet.imgsat(sprites_down, -1)
              
               self.images_left = spritesheet.imgsat(sprites_left, -1)
              
               # self.image, self.rect = load_png('player.png')
               screen = pygame.display.get_surface()
               self.image = self.images_up[1]
              
               img_rect = self.image.get_rect()
              
               self.rect = pygame.Rect(img_rect[0], img_rect[1], 
img_rect[2], img_rect[3]) # self.image.get_rect()
              
               self.area = screen.get_rect()
               self.side = side
               self.normal_speed = 5
               self.speed = 0
               self.direction = [0,0]
               self.state = "still"
              
               self.init_pos = pos   
               self.anim_state = 0

               self.reinit()

               ....

The player class is inherited by a simple Bot class, which currently 
only contains a few lines of code:

class Bot(Player, pygame.sprite.Sprite):
       def __init__(self, side, pos, spritesheet, sprites_up,
                     sprites_down, sprites_left, sprites_right):
           Player.__init__(self, side, pos, spritesheet, sprites_up,
                     sprites_down, sprites_left, sprites_right)

All stuff is initialized in the main function:
...
   # Initialise players
   global player1
   player1 = Player("up", [200,200], 'soccer.bmp',player1_images_up,
                    player1_images_down, player1_images_left, 
player1_images_right)

   global Bot1_1
   bot1_1 = Bot("up", [200,200], 'soccer.bmp',bot1_images_up,
                    bot1_images_down, bot1_images_left, bot1_images_right)

   global border1
   border1 = Border("left", [20,20], 'bande.bmp', [0,0,30,100], [30,0])
  
   # Initialise sprites
   global borders
   borders =  pygame.sprite.RenderPlain(border1)
   playersprites = pygame.sprite.RenderPlain(player1, bot1_1)

Sorry for copying that much code, but I really don't have a clue where 
this bug lurks ...

Any hints?

Thanks in advance

Sven
