* A lively and open development and support team is having fun improving and helping out :)
* The Box2D compatible version of ''Elements'' is being worked on, you can find the latest status in the git repository. We are still implementing Box2D's features and writing the documentation. In the meantime the Chipmunk engine is almost fully supported by the [[Elements/Chipmunk|previous version]] of Elements.

About

The Elements project is all about free and easy 2D physics for python and the XO laptop. It is used as the backend for the XO physics playground activity Physics.

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)
