WiiPhysics is a physics playground for the Wii, much like Crayon Physics or PocketPhysics. It uses Box2D and libwiisprite.

To show off some of the things you can do with wiiphysics; I'm going to start doing a weekly contest. No prizes sadly (Unless someone wants to step forward to sponsor and offer up a prize. But, the winner of the contest gets to choose the next weeks contest.) (A winner will be chosen by the wednesday following the contest end date).

  • Currently no contests are underway.

Bug Reporting

Any feature requests/ issues you'd like fixed should be reported here: http://code.google.com/p/wiiphysics/issues/list

Physics Tools Overview

Tools Overview:

  • Select - Use this tool to select objects, hold A to drag them around, hold A on an object and press B to toggle static/dynamic
  • Pen Tool - Hold A and draw a line with the pen. When you release A the ends of the line join up to form a shape.
  • Circle Tool - Press A to place a circle. Use + and - to increase/decrease the size.
  • Square Tool - Press A to place a square. Use + and - to increase/decrease the size.
  • Clear Screen (Bomb) - Clear everything. Useful to make some space, or when things start to lag.
  • Undo - Undo the previous action.


  • Rope Joint - Connect two objects by a rope
    • Click on two Objects to connect them
  • PinJoint - Create a rotation joint using 2 objects
    • Single Click on on an object(s) to set up a rotation relationship
      • Clicking on a single object pins it to the screen. Clicking on two items stacked up pins those objects together (e.g. Ragdolls))
  • Pulley Joint = Click on three objects to set up a pulley system
    • 2nd object is the pulley anchor
  • Prismatic Joint = Click on two points to set up a slider joint.
  • Weld Joint = Click on two objects to weld them together.

Object Control

  • Mobile Objects - Select this to place dynamic objects which move and obey gravity
  • Frozen Objects - Select this to place static objects which stay where you place them

Sim Control

  • Run - Run the simulation.
  • Stop - Freeze/pause the simulation. You should pause to place dynamic objects where you want them.


See in-game help for controls.
