Storyline

This video isn’t about a game storyline. It’s a developer walkthrough and pitch explaining why the programming language Zig is a strong choice for game development, including a demo of a small mini engine/project the creator built.

Gameplay / Project Highlights (Demo + What You Can Build)

“Hello World” Zig + raylib setup and rendering

The walkthrough demonstrates creating a minimal Zig app using raylib:

  • Create a Zig project
  • Add raylib as a dependency
  • Open a window and render a simple scene:
    • Set window width/height
    • Clear the background to sky blue
    • Use a main loop that draws each frame until the window closes
  • Emphasis: Zig’s build/dependency flow is described as more transparent than “mystical linking.”

Small custom engine (physics-sim oriented)

The creator then shows a small visualization/testing setup:

  • A small skybox/helix demo for testing
  • Mentions GOE / GPU- or render-related setup as “extremely easy” to get going
  • Interactive controls:
    • Adjust camera FOV
    • Add velocity to demonstrate motion/physics
  • Goal: use the engine for small physics simulations and extend it over time

Gameplay-Style Strategies / Key Tips Mentioned

Avoid “hidden work” with Zig philosophy

  • No hidden memory allocations
  • No hidden control flow
  • Manual memory allocation/deallocation using configurable allocators
  • The creator also dislikes C++-style ambiguity (e.g., mentions += possibly allocating heap memory)

Integrate existing C ecosystems

  • Zig can interoperate with C seamlessly
    • Example: use C libraries like raylib or SDL3
  • Prefer thin bindings (e.g., raylib bindings) to keep usage smooth in Zig

Build system workflow advantage

Zig’s build system is described as:

  • Easier than typical C setups (source builds, platform-specific GCC/CMake/Make frameworks)
  • Still offering control and visibility into what’s happening

Setup / Step-by-Step Guide (Dependency + Minimal App)

1) Install Zig

  • Download from Zig’s official download page, or
  • Use a package manager (example: Homebrew brew install zig)

2) Create a Zig project

  • Create a project directory
  • Run zig init-exe (generates multiple files including build.zig, build.zig.zon, src/main.zig, etc.)

3) Add raylib dependency

  • Follow the raylib-Zig binding repository instructions (includes a command snippet to fetch dependency code)
  • Edit build.zig to:
    • Link the library
    • Include the required import paths

4) Write the minimal application

In main.zig:

  • Import raylib bindings
  • Initialize a window (title, width, height)
  • Use defer to ensure the window closes
  • Run a loop until windowShouldClose():
    • Begin drawing
    • Clear background (sky blue)
    • End drawing
  • Run with: zig build run

Other Libraries / Ecosystem Recommendations Mentioned (How-to Direction)

  • raylib bindings The main “starter” example.

  • SDL3 success stories A project/port built with Zig’s build.zig to make SDL3 easier to integrate.

  • soLoud / so-call-like cross-platform audio/game helper library

    • Header-only, STB-like style
    • Helps abstract graphics API differences across platforms (e.g., Metal/OpenGL/DirectX)
    • Note: building across OSes was described as difficult; a “soLoud/Zig” variant aims to streamline that.

  • zig-gamedev ecosystem

    • A set of libraries/tools for making games in Zig
    • Caveat: tracks nightly Zig builds
    • The creator stays on Zig 0.13.0, so it wasn’t directly usable for their projects.

  • Mock engine

    • Compared conceptually to an ECS-powered engine (Bevy-like)
    • Open source, heavily in development, with extensive documentation

  • raylib + raylib Zig bindings repository (captions mention a phrase like “rayb/ray go” style bindings)
  • SDL3
  • soLoud / so-call Zig (header-only style; caption text is partially garbled but clearly references soLoud/“so-call Zig”)
