equilibriumengine's Introduction

Equilibrium Engine

Equilibrium Engine is a data-oriented and multi-threaded C11 game engine that takes advantage of ECS pattern followed by Hot-Reloading of your libraries and shaders which allows you to quickly iterate on different aspects of your projects.

Features

clang is the primarily supported compiler

Entity Component System & entity inspector
Engine UI & Scripts hot reloading
Shader hot reloading via file watcher
Forward & Deferred shading. PBR & HDR Tonemapping
cgltf or Assimp model loading
C99/C11 API with some links to C++ libraries such as BGFX & imgui
Crash protection against SEGFAULT, SIGABRT; in case your system accidentally accesses a NULL pointer or asserts in their callbacks - the engine won't crash and will fallback to its previous working library (currently Windows only)

Hot-Reloading of shaders & scripts

hot-reloading.mp4

Crash protection

Flecs entity inspector

flecs-entity-inspector.mp4

Usage

Equilibrium works on Windows via clang only and was tested some time ago on Ubuntu 20.04 LTS using GCC compiler. More work needs to be done to make sure the engine runs perfectly on both Linux & Mac.

To get started on Windows

You might need Visual Studio build tools installed so clang can link to MSVC static libraries. In case if Visual Studio is your primarily IDE please consider following these steps and check the issues section if you have troubles building the engine.

The rest of the dependencies included within the project:

assimp
bgfx
cglm
cgltf
cimgui
cr
flecs
SDL2
x-watcher

equilibriumengine's Issues

Update flecs

Looks like it has outdated flecs version, need to update it

Can't compile

I was trying to check out the project, but I can’t get it to build. Are there any special configuration steps or requirements that are not mentioned in the usage section of the readme? I generated a vs2022 solution using cmake with x64 target and all options on default. Out of the 23 projects, 5 fail, most notably equilibrium, editor and sandbox. In the equilibrium project I’m getting 780 compiler errors, most of them, if not all, are on invalid calls to flecs and bgfx according to error log. Meanwhile, all bgfx projects and flecs build fine... Do you have any idea what I might be doing wrong?
