Additional Details

How It Works

• It's a client side authorative game
• All validation happens on client-side ( in future it would be migrated to server-side authorization)
• server manages socket connection and brodcasting updated events to other clients

CPU Bot (A* Pathfinding)

• Map is converted into a grid.
• Bot computes shortest path to the player.
• Recalculates when obstacles or player movement change.
• Moves smoothly along generated path.

Running Multiple Clients

• Open multiple browser tabs

• Each tab becomes a new player connected to the server

• CPU bot tracks closest human player dynamically
