The examples are presented in no particular order and only briefly highlight things of interest, while it should not be considered a guide to programming with Jipmunk it should give a useful insight.
By executing:-
ant example.ExampleMenu
within the root of the jipmunk project you will be presented with a convienient menu with which you can select which demo to run. Just select the name of the demo from the required and click go!
This shows that by using a large collection of small segment shapes it is possible to create complex and even concave collision shapes.
In addition to the normal ability to drag object with the mouse button you can also add aditional vertexes to the polygon. All the really clever stuff happens inside the utility class ConvexHullUtil provided by jipmunk.
The first time I saw Chipmunk this really impressed me, no interaction here just enjoy.
This is a really neat example, it's only the boxes initial velocity and their attraction to the planet object that has any influence here so they are genuinely orbiting! The example demonstrates using a BodyVelocityFunc class which is used to provide custom gravity vector (always in the direction of the planet and not just in a single direction)
This to try, if you're very careful you can throw a box back into orbit. Speeding up the planet (try 2!) boxes stacking above a certain height on the planet with be thrown back into orbit...
No real interaction required. Shows creation of PolyShape shapes, also shows use for the SpaceBodyIteratorFunc class to iterate over all the bodies in a space. Unless a small subset of bodies in your application have a different and specific behavior there is often no need to keep your own lists of bodies.
This show the use of a number of different joint (constraint) types, also by using the layers bit pattern it is possible to prevent certain parts of the pump from colliding with itself. Use the arrow keys to control the speed of the pump. This should inspire any budding Rube Goldberg's out there!
This is just a simple stack of boxes that would be stable if it wasn't for that ball... Because of its simplicity its probably a good point to start experimenting from.
Jipmunk is capable of stable stacking even of precarious structures. Something to try is running the simulation in slow motion (change the step delta time) and nudge a central box, it can be interesting to see how a collapse propagates.
Like the Planet example this uses a rogue body to create a rotating shape that is not effected by the rest of the simulation. The boxes within it are effected by this shape and so are tumbled about.
