A Tron style light bike arena for 1 to 4 players on one keyboard. Your bike leaves a trail. Hit a wall or a trail and you're out. Cut people off, last one alive wins. In solo mode AI bikes hunt you instead.
I made it for my Programming 1 exam at INN (autumn 2025). C++ and raylib, my own vector class for all the movement math.
Play it in the browser: sundorigin.org/vector-clash.html or on itch.io

- 1 to 4 players on one keyboard, or solo against AI bikes. Trick them into crashing to raise your "duped" count. On Hard and Chaos more of them keep showing up.
- 4 bikes. Standard, Viper (fast and twitchy, tiny), Bruiser (slow, huge, grows tail fast) and Ghost (quick, barely leaves a tail)
- 6 maps. Clean, Fixed, Wave (sine waves), Donut, Grid and Chaos (new random obstacles every round)
- 4 difficulties. Easy, Normal, Hard and Chaos
- Power ups. Speed boost, a fake one that slows you down (sorry), Ghost mode to phase through trails, and Tail Cutter
- Gamepad support, 6 music tracks, a spawn shield after the countdown, solo high scores saved to a file
| Turn left | Turn right | |
|---|---|---|
| Player 1 (red) | Left arrow | Right arrow |
| Player 2 (orange) | A | D |
| Player 3 (green) | F | H |
| Player 4 (yellow) | J | L |
In the menu:
| Key | What it does |
|---|---|
| Up / Down | Number of players |
| Each player's turn keys | Pick a bike |
| M | Next map |
| Tab | Difficulty |
| T | Next music track |
| Enter / Space | Start |
| Space / Enter on game over | Play again / back to menu |
Gamepads: gamepad 1 steers player 1 and so on (d-pad or left stick). In the menu A or Start starts, d-pad up/down sets players, X changes difficulty, Y changes map, Back changes music and LB/RB pick your bike. On game over A retries and B goes back to the menu.
Windows, Visual Studio: open VectorClash.sln and press F5. raylib is in lib/. Music and sounds load from resources/, so run it from the project folder (the default in Visual Studio) or put resources/ next to the exe.
src/main.cpp window and game loop
src/GameManager.* states, menu, rounds, scoring, audio, saving
src/mPlayer.* player bikes and input
src/Enemy.* the AI bike
src/ITailOwner.h shared trail logic for players and the enemy
src/BikeConfig.h bike stats, all the balancing in one place
src/MapGenerator.* the six maps
src/PowerUp.* power ups
src/Vector2D.* my own 2D vector math (normalize, rotate, sine and cosine movement)
This is the newest version of the code. On top of the exam version it has gamepad support (pad N steers player N) and a 4 second spawn shield that starts after the GET READY countdown. The browser parts only switch on when you build with PLATFORM_WEB, so the same code builds for Windows too. All changes are marked // [web-port] or // [gamepad], and web/WEB-PORT-NOTES.md explains them plus the web build command.
The exact version I handed in for the exam is on the 2025-exam branch.
The ready to play browser build is in web/VectorClash-web.zip. Unzip it and serve the folder with any local web server, or upload it to itch.io as an HTML game. The music is free to use tracks I downloaded.
