I know that some other people already did this, but I made this simple double pendulum simulator just for fun. It solves the differential equation system using the standard 4th order runge-kutta method and allows you to edit the initial conditions within a certain range. It also displays the angular position of both masses on a plot, so it gives a certain intuition of how the system behaves.
Hope you like it!
I made this simple 2D heat simulation to experiment a bit with PICO-8. It solves the steady-state heat transfer equation iteratively using the Gauss-Seidel method and it shows the evolution of the solution at each step. During the simulation the fps gets a bit low since the grid is fairly big (128x128), but anyway I think it gave an interesting result so I decided to post here! I hope you like it.
You can edit the configuration of the simulation using the mouse functionality to add or remove high and low temperature boundaries. If a boundary does not have a fixed temperature block it is considered an open boundary (dT/dx=0 or dT/dy=0).
Thanks and all feedbacks are very welcome!
First game using Pico-8! So happy I could finish a game by myself and actually post it.
Anyway, hope you enjoy despite of being super simple and of course let me know if you have any suggestions for the future :)
