zig-gamedev project

We build game development ecosystem for Zig programming language, everyday since July 2021. Please consider supporting the project. We create:

Cross-platform and composable libraries
Cross-platform sample applications
DirectX 12 sample applications
Mini-games (in planning)

To get started on Windows/Linux/macOS try out physically based rendering (wgpu) sample:

git clone https://github.com/michal-z/zig-gamedev.git
cd zig-gamedev
zig build physically_based_rendering_wgpu-run

Vision

Very modular "toolbox of libraries", user can use only the components she needs
Works on Windows, macOS and Linux
Has zero dependency except Zig compiler (master) and git with Git LFS - no Visual Studio, Build Tools, Windows SDK, gcc, dev packages, system headers/libs, cmake, ninja, etc. is needed
Building is as easy as running zig build (see: Building)
Libraries are written from scratch in Zig or provide Ziggified bindings for carefully selected C/C++ libraries
Uses native wgpu implementation (Dawn) or OpenGL for cross-platfrom graphics and DirectX 12 for low-level graphics on Windows

Sample applications (native wgpu)

Some of the sample applications are listed below. More can be found in samples directory.

physically based rendering (wgpu): This sample implements physically-based rendering (PBR) and image-based lighting (IBL) to achive realistic looking rendering results.
zig build physically_based_rendering_wgpu-run
audio experiments (wgpu): This sample lets the user to experiment with audio and observe data that feeds the hardware.
zig build audio_experiments_wgpu-run
bullet physics test (wgpu): This sample application demonstrates how to use full 3D physics engine in your Zig programs.
zig build bullet_physics_test_wgpu-run
procedural mesh (wgpu): This sample shows how to efficiently draw several procedurally generated meshes.
zig build procedural_mesh_wgpu-run
gui test (wgpu): This sample shows how to use our zgui library.
zig build gui_test_wgpu-run

Sample applications (DirectX 12)

Some of the sample applications are listed below. More can be found in samples directory. They can be built and run on Windows and Linux (Wine + VKD3D-Proton 2.8+):

bindless: This sample implements physically based shading and image based lighting to achive realistic looking rendering results. It uses bindless textures and HLSL 6.6 dynamic resources.
zig build bindless-run
rasterization: This sample application shows how GPU rasterizes triangles in slow motion.
zig build rasterization-run
simple raytracer: This sample implements basic hybrid renderer. It uses rasterization to resolve primary rays and raytracing (DXR) for shadow rays.
zig build simple_raytracer-run
mesh shader test: This sample shows how to use DirectX 12 Mesh Shader.
zig build mesh_shader_test-run

Others using zig-gamedev

Aftersun - Top-down 2D RPG
Pixi - Pixel art editor made with Zig
Simulations - GPU Accelerated agent-based modeling to visualize and simulate complex systems
elvengroin legacy - TBD
jok - A minimal 2D/3D game framework for Zig

Building sample applications

To build all sample applications (assuming zig is in the PATH and Git LFS is installed):

git clone https://github.com/michal-z/zig-gamedev.git
cd zig-gamedev
zig build

Build artifacts will show up in zig-out/bin folder.

zig build <sample_name> will build sample application named <sample_name>.

zig build <sample_name>-run will build and run sample application named <sample_name>.

To list all available sample names run zig build --help and navigate to Steps section.

Build options

Options for Windows applications:

-Dzd3d12-enable-debug-layer=[bool] - Direct3D 12, Direct2D, DXGI debug layers enabled
-Dzd3d12-enable-gbv=[bool] - Direct3D 12 GPU-Based Validation (GBV) enabled
-Dzpix-enable=[bool] - PIX markers and events enabled
