Tick is a small game engine built using the Zig programming language.
- 2D Immediate Mode Renderer
- 2D Batched Renderer
- Immediate Mode GUI
- Generic linear math and quaternion library.
- Hot code reloading
- Easy integration with C Libraries
- Platform: Linux/GLFW
Zig is a systems programming language built on the LLVM compiler toolchain. It allows easy interfacing with C libraries by directly including their header files. It has an expressive but simple syntax, facilitates compile time evaluation of code, coroutines, and provides convenient error handling and nullable-type semantics. For more information, check out http://ziglang.org/
As well as the requirements for a Zig development environment, you will need:
- libc
- GLFW
- libsoundio
Set up your Zig development environment and run the following commands on your shell:
$ git clone https://github.com/raulgrell/tick.git
$ cd tick
$ zig build live
This will clone tick and cd into its directory. ´zig build live´ will build and run the live environment.
Zig will create an executable called 'dev', and a shared library 'libgame.so' that contains your game and the engine code. Both of these files will be inside the zig-cache directory. In order to update your game code, run:
$ zig build update
The hot-reload code is based on Chris Wellon's post http://nullprogram.com/blog/2014/12/23/, and there is a
port to zig in ./examples/live. Just adjust the makefile.
Changing the definition of the State struct may require a rebuild of the live environment.
You cannot change the function signatures of the API without a recompile of the live executable. I probably won't work on this, as it is only a minor inconvenience, and a major technical hurdle.
