I'll create a fully functional Connect 4 game with multiplayer functionality using React. Let's build this step by step!

This Connect 4 game includes:

Features:

• Two game modes:

  • Local multiplayer (two players on the same device)
  • Play against the computer AI
• Animated game pieces with drop effects
• Winning combination highlighting
• Game state management (win/draw detection)
• Responsive design that works on all devices
• Clean, modern UI with Tailwind CSS and shadcn/ui components

How to play:

1. Select a game mode (Local Multiplayer or Play vs Computer)
2. Click on a column to drop your game piece
3. Connect four pieces horizontally, vertically, or diagonally to win
4. Use the controls to start a new game or change the game mode

The AI opponent has basic strategy that will:

1. Make winning moves when possible
2. Block your winning moves
3. Prefer the center column for better positioning
4. Otherwise make a strategic move

You can expand this game further by adding features like:

• Online multiplayer using a service like Firebase
• Player statistics and game history
• Difficulty levels for the AI
• Custom player names and colors

Would you like me to explain any specific part of the implementation in more detail?

I'll fix the issues with the AI and win detection in the Connect 4 game. There are two main problems to address:

I've fixed two main issues in the Connect 4 game:

1. Fixed the AI Move Logic:

• The original code had a bug where the AI move wasn't properly being applied to the board

• Now the AI correctly:

  • Makes its own move on the board
  • Checks for wins after its move
  • Switches back to the player's turn

2. Fixed the Win Detection:

• The win detection algorithm had a flaw in how it counted consecutive pieces
• The new implementation properly checks for 4 connected pieces in all directions
• It resets the counter when encountering an opponent's piece or empty space

3. Improved the AI Strategy:

• Enhanced the AI's decision-making process
• Fixed the win detection in the AI's move evaluation
• Added better strategic play by preferring columns closer to the center
• Improved the blocking logic to prevent player wins

These changes should make the game work correctly, with the AI making proper moves and the win detection accurately identifying when a player has connected four pieces. The AI will now make more strategic moves while properly taking turns with the player.
