The ''Elements'' project is all about '''free and easy 2D physics for python''' and the XO laptop.
# An '''easy-to-use''', fast 2D physics API
#* for the (faster) [http://www.box2d.org/ box2d] physics engine (work in progress)
#* and [[Elements/Chipmunk|previously]] also for the [http://wiki.slembcke.net/main/published/Chipmunk Chipmunk] 2d physics engine (with [http://code.google.com/p/pymunk/ pymunk] ctypes bindings)
#* See: [[Physic Engines/Speed Tests]]
# Examples and documentation on how to use the API
# Providing the examples as bundles, as they are already interesting and fun
# Speed optimization (also with an eye on the XO laptop :)
# Development of ideas for education and playful-learning




: '''Watch [http://www.youtube.com/watch?v=NZNTgglPbUA this] and [http://www.youtube.com/watch?v=QsTqspnvAaI this] video to see where we are heading :)''' Our idea is especially to bring this tool to the XO laptop, together with a teaching and learning tool which can be used to share (mesh) different scenes and exercises

== More Information ==
* Source-Code is GPLv3 licensed - so do with it what you want! Even eat it :)
* 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.


== To Do ==
* Artwork (we need a nice logo :)
* Joints
* Please have a look at our tickets page: http://www.assembla.com/spaces/elements/tickets

== Feature Request ==
What features would you like to have implemented? :)

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)
