This project aims to be a 1:1 port from C to Odin of a classic "2D Shoot 'em up".

The primary goal of this repository is educational.

I created this project as a learning exercise to better understand the Odin programming language. The code is organized as a direct, structure-preserving translation of the original C source by Parallel Realities.

Note: This code does not follow idiomatic Odin best practices. Instead, it intentionally preserves the logic, data structures, and flow of the original C implementation. This makes it easier to compare both versions side by side and understand how C constructs translate into Odin.

A huge thank you to Parallel Realities for creating such an excellent and comprehensive set of tutorials. You can find the original C-based tutorials and information on where to get the original C source code here: https://www.parallelrealities.co.uk/tutorials/#shooter

To build and run this project, you will need:

• The Odin compiler installed and available in your PATH
• SDL2 (see note below)

Note: Odin provides SDL2 bindings and prebuilt libraries under its vendor directory. To run the game, make sure the SDL2, SDL2_mixer, and SDL2_image libraries (.dll or .so) are available in your PATH, or copy them into the project directory.

1. Clone this repository
2. Install the required SDL2 dependencies for your platform
3. Run the project:

odin run .

If you want to debug the project, I personally recommend RAD Debugger (THE debugger).

It has been used extensively during development to inspect execution flow, track down bugs, and better understand how the translated code behaves compared to the original C version.

Tested on:

• Windows 10

• This is a learning project, not a production-ready codebase
• Expect C-style patterns rather than idiomatic Odin
• The goal is clarity and comparison, not optimization
• Future improvements may include a refactored and a more idiomatic Odin version

However, it's a direct Odin port of the original C tutorials by Parallel Realities: https://www.parallelrealities.co.uk/tutorials/
