* The ''Elements'' project derived from [[pymunx]], which started as examples for pymunk and is growing up to a real physics api for python
* The 2D physics is handled by the chipmunk physics engine (written in C by ...)
* Communication to the chipmunk library is done via the pymunk ctypes bindings (by Victor Blomqvist.)
* A lively and open development and support team is having fun improving and helping out :)

Pygame Example

The typical usage in pygame can look like this:

      import pygame
      from pygame.locals import *
      from pygame.color import *   

      from elements import *
       
      pygame.init()
      screen = pygame.display.set_mode((800, 800))
      clock = pygame.time.Clock()

      world = elements()
      world.add_wall((100, 200), (300, 200))
         
      # Main Game Loop:
      while running:
         # Event Handling
         # Maybe calling world.add_ball(event.pos) or world.add_square(event.pos)
         # ...

         screen.fill((255,255,255))

         # Update & Draw World
         world.update()
         world.draw(screen)

         # Flip Display
         pygame.display.flip()
          
         # Try to stay at 50 FPS
         clock.tick(50)
