🧩 Code Clash

Code Clash is a fast-paced, 1v1 multiplayer puzzle game built in Unity, inspired by classic code-breaking games like Mastermind. Players go head-to-head to crack their opponent's 4-digit secret code before time runs out, all while interacting through live voice chat and expressive emojis!

🎮 Game Concept

1. Set the Code: At the start of the match, each player selects a secret 4-digit number (e.g., 5281). Players cannot see each other's codes.
2. Take Turns: The game is turn-based. When it's a player's turn, they have 30 seconds to guess the opponent's secret code.
3. Make a Guess: Players input their 4-digit guess using an in-game numpad built directly into the game's UI.
4. Instant Feedback: The system compares the guess against the opponent's code. If a digit is correct and in the exact right position, it is revealed.
   • Example: Secret is 5281. Guess is 5284.
   • Result: 5 2 * * (The exact matches are shown in green, while incorrect digits remain hidden as asterisks/underscores).
5. Winning: The first player to successfully guess the full 4-digit code (5 2 8 1) wins the game, while the opponent loses.

✨ Key Features

• 1v1 Online Multiplayer: Secure, server-authoritative turn-based gameplay where secret codes are never exposed to the client.
• In-Game Numpad: A sleek, interactive on-screen number pad for quick and intuitive code entry.
• Voice Chat & Emojis: Communicate, bluff, or taunt your opponent using live proximity/room voice chat and a quick-select emoji reaction system (inspired by UNO).
• Turn-based Timer: A strict 30-second countdown per turn to keep the pressure high.
• Interactive UI: Clean and intuitive Main Menu, Matchmaking Lobby, Code Selection screen, and Gameplay dashboard.

🛠️ Tech Stack & Requirements

• Engine: Unity (2D or 3D)
• Language: C#
• Networking: Unity Netcode for GameObjects / Mirror / Photon (PUN/Fusion)
• Communications: Photon Voice, Unity Vivox, or Dissonance for voice chat.

🚀 Development Roadmap

Following an iterative development process, the project is structured into logical phases:

• Phase 1: Core Mechanics (Offline)
  • Setup the Unity project and basic UI flow (Menu -> Code Selection -> Gameplay).
  • Design and implement the in-game numpad UI.
  • Implement the core code comparison logic (string matching).
• Phase 2: Game Loop & Timers
  • Integrate the 30-second countdown timer.
  • Implement local turn-switching logic.
• Phase 3: Online Multiplayer
  • Integrate a networking solution (e.g., Photon or Netcode).
  • Implement server-side verification: clients send guesses to the server, and the server returns the parsed result.
  • Synchronize the timer and turn states across the network.
• Phase 4: Social Features (Voice & Emojis)
  • Integrate a Voice Chat SDK for live 1v1 communication.
  • Create the Emoji UI panel and network the emoji triggers so both players see reactions in real-time.

💻 Core Logic Snippet

A sneak peek at the simplified logic used to verify a player's guess against a secret code:

string secret = "5281";
string guess = "5384";
string result = "";

for(int i = 0; i < 4; i++)
{
    if(secret[i] == guess[i])
        result += secret[i]; // Correct digit & position (Green)
    else
        result += "*";       // Incorrect (Hidden)
}

// Output: "5*8*"
