Pygame Clamp-IP小​​故障？

Question

我有一個pygame的clamp_ip（）方法的問題。我似乎無法弄清楚問題所在。我爲我的相機有一個矩形，並且叫player.clamp_ip(camera)，但它無法鉗位。我的代碼在github上。我也使用Python 3.4運行最新的pygame。另一個令人擔憂的是它沒有引發任何錯誤。

    ##Setup

    #Game Variables 
    gamevariables = { 'blitcarrotfield':True, 'surroundings':'Start', 'endofgame':False, 'camerax': 320, 'cameray':240 } #Create the variable dictionary 

    #Storyline... 
    printtext(gameScreen, 'Once there was a storyline', textures, gamevariables['blitcarrotfield'], player, timeout=5) 

    log('Game Setup successfully completed\n') 




    ##Mainloop 
    while True: 

     for event in pygame.event.get(): #Event loop 
      events = eventhandler(player, textures, gamevariables, event, pygame.key.get_pressed(), gameScreen, sounds) #Handle events 
      if events == 'End': 
       gamevariables['endofgame'] = True 
     blit(gameScreen, gamevariables, textures, player) #Blit objects 
     gamevariables['camerax'] = camera.x 
     gamevariables['cameray'] = camera.y 

     player.rect.clamp_ip(boundaryRect) 
     player.rect.clamp_ip(screenRect) 
     player.rect.clamp_ip(camera) 
     camera.clamp_ip(boundaryRect) 
     pygame.display.flip() 

     if gamevariables['endofgame']: #If the game has ended: 
      pygame.quit() 
      log('----- Game end -----') 
      stoplog = True 
      logfile.close() 
      sys.exit(0) 

在此先感謝！

我用一個矩形將相機可視化，它不在屏幕上。
