WiiPhysics

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

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.

Joints

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.
