Interactive 2D Spring Physics * Drag a corner to manipulate a shape * Tap space while dragging to fix a point (drag again to release) * Slide the sliders to affect the physics engine. * Slide for lower slider to change the speed of the conveyor belt. * Press 'R' to reset the simulation... * Press '1, 2 or L' to spawn new shapes... (SLOW!) Adding collision detection and resolution has (as expected) slowed the whole things down a lot! :( You've probably seen these before on Scratch (Sometimes called Elastic Physics?)... I first wrote one around 14 years ago in Turbo Pascal *grin* - Crazy huh! This is just a quick test to make sure things work fast enough in Scratch. I wanted to add collision detection, that was the aim, but I'm not feeling confident that Scratch can handle the math fast enough.
