Simon got seriously hooked on Matter.js, a a 2D JavaScript physics library that supports rigid body collisions and constraints.
He started with Daniel Shiffman intro to Matter.js, downloaded it using GitBash and then went on by following further Matter.js tutorials on Daniel Shiffman’s channel. Simon built two physics simulations with static shapes and circular bodies: one resembling a waterfall and another resembling a dangling chain. The sketches involved constraints for mouse interaction. Simon also learned how to delete off-screen bodies from the physics world, removing them from both his particle array as well as Matter.world.
