Install with go get github.com/antosmichael07/Raylib-3D-Custom-First-Person

Example

The function player.UpdatePlayer() has to be at the last lines of the game loop, because it draws on screen Press E to interact, if it was at the first lines of the game loop, then it would be under every other thing that you draw.
