🤔 About the project

This project is a simple experiment with ray casting and C. It's not really a game, but rather a proof of concept. You can walk around and observe the environment, which consists of walls and an open sky.

I previously made something similar in Python, but it was quite slow (~100 fps), so I wanted to see how fast it could be in C (it's ~2000 fps). I also really like C and ray casting, so it's a fun project indeed.

💻 Built with

• C99
• CMake
• SDL2

Tip

On Debian-based systems, you can install all necessary dependencies with:

sudo apt-get install -y cmake libsdl2-dev libsdl2-gfx-dev

🚀 Getting Started

Tip

You can also download a pre-built binary.

To get a local copy up and running, follow these simple steps:

git clone https://github.com/reznakt/ray-casting.git && cd ray-casting
cmake -B build/
cmake --build build/ -j$(nproc)

🎮 How to Play

Currently, there are no game features per se. You can walk around and observe the environment. However, you can configure various parameters by modifying the header files:

• Screen size
• Field of view
• Number of rays
• Keymappings
