Computing PI using Unity game engine's built in physics with colliding blocks (3Blue1Brown way)

Показать описание
3Blue1Brown showed an interesting way to compute Pi with colliding blocks, but does it only work in pure math (without precision errors), or will it also work with standard game engine's physics? I tried to reproduce computing Pi with colliding blocks in Unity - and it worked!

This video is great! When I saw that 3Blue1Brown video, I never thought to make it work in unity. Really good job! But I think you can write your own physics to get closer to math numbers. I believe unity physics is not to simulate that many collisions but rather to simulate somewhat realistic looking physics. You don't need to write anything fancy. You can make them transfer velocities when two objects intersect

i programmed 3b1b's simulation in unity expecting it not to work, and somehow it did
