This project requires PHP >=8.0.5 because it contains a very important bugfix to the FFI extension: https://bugs.php.net/bug.php?id=80847.
Make sure you have the raylib 3.5.0 library installed locally before running the project. See https://www.raylib.com/.
The above screenshot presents (in debug mode) the weights applied with the A* pathfinding algorithm. The darker squares are the chosen path towards the destination.
This project uses an experimental library I'm writting, named raylib-ffi.
