POC Python Raycaster on Pygame

Raycaster engine is inspired by 90's PC games. It takes three inputs:

• 2D array representing the map
• Player (coordinates, angle of view)

How to play

• G / H - after mouse select on minimap build/destroy tower
• W / S - move forward/backward
• A / D - turn left/right
• Q / E - strafe left/right
• deprecated UP / DOWN - level of detail
• deprecated P - perspective correction on / off
• deprecated L - dynamic lighting on / off
• Mouse click on minimap - execute move to the selected place by using Dijkstra's Shortest Path First algorithm.

9.1.2023 version (d8143365b81375b5ca68592544fd6ab3da7cbf54):

Features

• POC floor and ceiling render

19.11.2022 version (405b1bae47b3b76bd0297029ba62814bf6be082b):

Features

• Raycasting and texture mapping rewritten into Rust. Result 50x faster.

04.04.2020 version (e548d8ef46d51d38eaf9363b63c414a916d9b533):

29.03.2020 version (c8df8d6e7a37e62a841591f972fa33e5d198b1f9):

Features

• POC floor/ceiling

22.03.2020 version (118bc4dbd1432d8a9ff032ca6f0aa815553f4ee1):

Features

• removed PIL library from dependencies, using pygame image lib instead
• added scaled images of tarrain to the minimap

22.03.2020 version (58697ea11fde85f633341bb4dff89c6a62e46097):

Features

• (huge performace increase) rewritten graphics renderer to use native pygame line/rect interface instead of directly interfacing with canvas on pixel basis
• tower defense game mechanics
• spawning creeps with health and level
• building and destroying towers by selecting empty space/tower and using keys G/H

13.03.2020 version - Added object zbuffer and renderer for transparent items in the map

01.03.2020 version - Dijkstra's Shortest Path First algorithm for minimap mouse click, dynamic lighting on/off, perspective correction on/off

19.02.2020 version - engine migrated from Tkinter to Pygame, big cleanup of code

28.01.2020 version - POC Python Tkinter Ray caster
