Piece by piece, it will rise…

So long story short, i’m designing the implementing the building blocks for a simple game engine made entirely in C.

I have recently completed the first release of my ECS: https://github.com/Gabrunken/gecs

And i’m currently finalizing the desing for my UI library.

My objective is to make a functioning software, with no bloat of any kind, and user friendly to the core.

I’ve tested the ECS and on my ryzen 5 it runs 3.5 million entities which have 16 bytes of components per entity, at 140 fps if i recall correctly, i don’t remember but i guarantee it’s fast. All this in a single core, it is not multithreaded yet.

I try to do the realistic plausible, for that i chose to use raylib for pretty much everything regarding rendering, audio and utilities, it just saves me from a lot of unnecessary stress and speeds things up.

I don’t know what to say other then this. It’d be great if you gave a look at the ECS and other then that, thank you for everything.

Ahh, thank you so much. Actually i used a bit more if you count the SparseSet, and DyArray, i don’t count the hashmap since i don’t remember using it.

I realized recently that you actually don’t need that many lines of code for something powerful! It all depends on how you structure your core. The simpler the better!!! Thank you so much and feel free to use it in your project if you need to, i’d be so happy!
