Videos To Show Off Various Game Features

Create, Join, and Spectate Games

• The player who creates the game is always blue
• The player who joins the game is always red
• Any player after the first two who join a game is a spectator (cannot move any pieces)

Create_And_Join.mp4

Players can only move their pieces during their turn

• Every move is updated on each player/spectator's board without the need to manually refresh
• The blue/red circles above are highlighted (in green) to show which player is meant to move next
• Spectators can ONLY spectate. They cannot move any pieces

Move_Mechanics.mp4

Players can rejoin the match and will be able to resume with their correct pieces

• The player name can be seen as an ID. Once a player creates/joins a match, if they are assigned to that color, the REDIS database will remember which pieces they control

Interesting Features To Point Out

Running on Digital Ocean Infrastructure

Summary

• Has 1 Droplet (Titan)
• Has 1 Managed Database Cluster
• Has 1 Google Domain (titan-backend-nyc.com)

Security

• Firewall Setup:
  • SSH on Port 22 only allowed from my IP and titan itself. This was necessary because it is exposed to the internet there were thousands of login attempts per minute on the droplet from global IP addresses
  • TCP (Port 81) from my IP address. This is to allow myself to manage the Nginx Proxy Manager application
  • TCP (Port 443 -> HTTPS) for all IPv4 and IPv6 addresses to allow any user to interact with the Vercel front end UI
  • All requests are proxied through an Nginx proxy to allow a client to hit a HTTPS endpoint even though Titan runs on HTTP
