Re: [pygame] exact algebraic numbers?
Hi Mike, Such algebraic numbers are used in computational geometry, you can take a look at CGAL http://www.cgal.org, it's a powerfull Computational geometry written in C++ (a python binding exists) and it has an algebraic kernel for exact computation of points on a circle or on a sphere. I'm not sure that it includes the transformations because it is done to maintain data structures like meshes, etc... Well you have to see if it suits your need and if the effort of installing it is woth it! Regards.

Yeah I did that and it's perfect, here is the link, Rene gave it to me, maybe it can help someone else : http://thorbrian.com/pygame/builds.php 2009/11/15 Lenard Lindstrom > Hi rouiller, > > Somehow the joystick extension module is being compiled with the debug > switch set (DEBUG macro defined).

Re: [pygame] Spam problem with joystick module
The calls to get_axis and get_button cause these outputs...

Re: [pygame] Spam problem with joystick module
Here is the code I use to test the pad, I found it on the net. pygame.init() #joystick.init() j = pygame.joystick.Joystick(0) j.init() #print 'Initialized Joystick : %s' % j.get_name() try: while True: pygame.event.pump() for i in range(0, j.get_numaxes()): if j.get_axis(i) != 0.00: pass #print 'Axis %i reads %.2f' % (i, j.get_axis(i)) for i in range(0, j.get_numbuttons()): if j.get_button(i) != 0: pass #print 'Button %i reads %i' % (i, j.get_button(i)) except KeyboardInterrupt: j.quit() As you can see I commented the prints but I still have the same output : SDL_JoystickGetButton value:0: SDL_JoystickGetButton value:0: SDL_JoystickGetAxis value:-257: SDL_JoystickGetAxis value:-257: SDL_JoystickGetAxis value:-257: SDL_JoystickGetAxis value:-257: SDL_JoystickGetButton value:0: And so on... Were you able to use a joystick without output? If so do use a different of pygame or python?

[pygame] Spam problem with joystick module
Hi everyone, I am trying to use a gamepad for a game project but whenever I check for a pad event I get some printing in the console. I saw some discutions about the subject but no solution. I am on windows7 python26 pygame191 and I develop on Eclipse with pydev. Does someone have encounter the same problem and found a solution? Thx for your help. Regards.
