Wolfenstein 3D like raycaster using Macroquad in Rust running on the web

## Features

- Digital differential analyser (DDA) raycaster

	- Like Wolfenstein 3D

- Textured walls

	- With multiple textures

- Minimap

- Ability to look up and down

- Fog effect

- Wall collisions

- This was mostly a proof of concept

	- The math was actually pretty fun to figure out and I have used the reverse of it (screen positions to angles, distances, etc) for robotics 

## Showcase

![Showcase 1](./Showcase/Screenshot1.png)

![Showcase 2](./Showcase/Screenshot2.png)

## Controls

- WASD to move

- Arrow keys to turn/look around

- R to replay "loading" animation

- Mouse to movement to look around (must click inside window to grab mouse)

- Tab to release mouse grab

## Copyright stuff

- Textures are from ID Software's Wolfenstein 3D

## Bugs

- Speed

	- Only CPU bound?

- Mouse grab on Windows??

- Mouse grab on web?
