# SDL2 Raycaster
A basic SDL2 raycasting engine written in C++. Raycasting is a rendering technique to create a puedo 3D game from a 2D map. This was done by casting rays for each horizontal screen pixel and calculating the length of the rays using DDA algorithm.

## Setup
### Linux:
First, make sure you have a C++ compiler installed. Then, install SDL2 and CMake:
```
sudo apt-get install libsdl2-dev cmake make g++
```
Build and compile:
```
cmake
make
```
### Windows:
Download and install VS with C++ or MinGW-w64. You also will need to download SDL2 for Windows. Then, change the path in CMakeLists.txt to your /SDL2/ folder.
Make sure `SDL2.dll` is in the right directory.
Build and compile:
```
cmake .. -G "Visual Studio 16 2019" -A x64
cmake --build . --config Release
```
Replace "Visual Studio 16 2019" with your version of Visual Studio.
