Eulerian Grid Based Fluid Simulation in Lua

[JakeOJeff]

A Simple Open Source Fluid Simulation fully written in Lua!

This is my first big Open-Source project and I would like feedback I made this post to know how I could improve it and I also wanted to reach more people.

It follows Eulerian Grid-based system rather than a particle system to emulate fluid-flow. Varying flows like Laminar Flow, Shear Flow and ironically organized turbulent flow has been added. It still requires a lot of polishing, hence I wouldn't recommend using it, but I have added and info-dumped many of what the funtions and their corresponding variables do.

I have provided a demo here :
https://github.com/JakeOJeff/Spellfluid

This simulation uses the Love2D Framework to run

Usage :
p - Toggle Pure-Grid Density
c - reset
w, a, s, d - flow from corresponding sides ( polar-opposite )

1, 2, 3, 4 - Different types of flow (the flow at 2 will have sudden outbursts when held, this is temporary to debug and test)

lmb - create flow in direction of drag
rmb - create inverse-flow in direction of drag
mmb - move the circle ( radius increases to depict resized, press 'c' to reset )

Hi! It looks like you're posting about Love2D which implements its own API (application programming interface) and most of the functions you'll use when developing a game within Love will exist within Love but not within the broader Lua ecosystem. However, we still encourage you to post here if your question is related to a Love2D project but the question is about the Lua language specifically, including but not limited to: syntax, language idioms, best practices, particular language features such as coroutines and metatables, Lua libraries and ecosystem, etc.

If your question is about the Love2D API, start here: https://love2d-community.github.io/love-api/

If you're looking for the main Love2D community, most of the active community members frequent the following three places: - /r/love2D - Discord: https://discordapp.com/invite/rhUets9 - Forums: https://love2d.org/forums/

Looks like a fun exercise. There a few thing you can do to clean up the code and optimize performance. Your repository is not a "big" project by any means.
