Posted on OpenProcessing: UPhysicsBox3D03 (trails mode shown)

While preparing for yesterday’s Advanced Topics workshop I indulged in playing around with Mr.Shiffman’s PBox2D (GitHub) Processing wrapper of JBox2D. Above is a snapshot of the quick-and-dirty result: UPhysicsBox2D03 features a grid of sloping boundaries that you can drop balls through Pachinko-style.

Turn on the “DrawTrails” toggle to switch from normal drawing to a trails mode where you can see the trail of balls bouncing and falling through the grid. There’s also a “timeout” feature that deletes balls that don’t move for a given amount of time. Right now they just blink out of existence, I could think of much better ways but will need to have a closer look at the API first.
