Typically, when you get this error, there's something wrong with your recursive function. What it appears to be doing is within your add function, its calling itself again. I think you might be wanting to call super(C, self).add(spr) where C is the class you created which has the add method. -Tyler On Fri, Apr 24, 2009 at 5:27 PM, Yanom Mobis ya...@rocketmail.com wrote: this code level1 = [(0,0), (20, 0), (40, 0), (60, 0), (80, 0), (100,0), (120,0), (140,0), (160,0), (180,0), (200,0), (220,0), (240,0)] #positions of enemies #yatta yatta def setenemies_lvl1(): # put enemies on screen. pygame.display.set_caption(Loading Level) #tell player it's loading for item in level1: #loop throug coords in level file: lvl1 enemies.add(random.choice((enemyblue.png, enemycyan.png, enemygrey.png, enemyyellow.png)), item, enemybullets) pygame.display.set_caption(PyStarFighter) #tell player it's done is causing this problem: File /usr/local/lib/python2.6/site-packages/pygame/sprite.py, line 325, in add self.add(spr) alot of the same message File /usr/local/lib/python2.6/site-packages/pygame/sprite.py, line 316, in add if isinstance(sprite, Sprite): RuntimeError: maximum recursion depth exceeded while calling a Python object -- Visit my blog at http://oddco.ca/zeroth/zblog

Re: [pygame] Never seen this before
Okay, I had assumed you had written your own python class, subclassing one of the Group classes, and had used .add within the overridden method. I've made that mistake myself. Looking at your code, I see the issue. For one, Group.add takes in a list of sprites. You are passing in three separate arguments, and Group.add is thinking they are each sprites. You should change enemies.add(random.choice((enemyblue.png, enemycyan.png, enemygrey.png, enemyyellow.png)), item, enemybullets) to enemies.add(Enemy(random.choice((enemyblue.png, enemycyan.png, enemygrey.png, enemyyellow.png)), item, enemybullets)) The super method can take a class and an object as parameters, and it will call the method on the superclass of the class given. It is the same as Basicsprite.__init__(self, img) For reference, here is the documentation about Group.add: http://www.pygame.org/docs/ref/sprite.html#Group.add -Tyler On Sat, Apr 25, 2009 at 6:34 AM, Yanom Mobis ya...@rocketmail.com wrote: the two files for the game are attached --- On *Fri, 4/24/09, Brian Song unlucky...@gmail.com* wrote: From: Brian Song unlucky...@gmail.com Subject: Re: [pygame] Never seen this before To: pygame-users@seul.org Date: Friday, April 24, 2009, 9:57 PM If the problems fixed, yay.
