: It features properties to modify the color of the divider grids and change the stroke width of the winning line strike-through. Step-by-Step Implementation Guide
Imagine the AI looking into the future. When it is the AI's turn, it generates a tree of every possible move, then every possible opponent counter-move, and so on, until the game ends.
// Example Event: Handling a user grid selection When Btn_11.Click do: Call TicTacToe1.PlaceMove (row = 1, col = 1) // Example Event: Reflecting the logic back to the UI When TicTacToe1.X_Placed (index) do: Set matching_button.Text to "X" Set matching_button.Enabled to False When TicTacToe1.GameOver (winner) do: Call Notifier1.ShowMessageDialog (message = winner + " has won the match!") Use code with caution. Why Use an Extension Over Native Blocks? Development Metric Native App Inventor Components With io.horizon.tictactoe.aix Requires roughly 200–400 messy layout blocks. Requires fewer than 30 direct layout blocks. Logic Verification Manual conditional checks for 8 winning paths. Automated instantly via internal Java methods. Error Vulnerability High risk of grid index overlap or variable bugs. Safe, built-in index protection framework. Online Scalability Complicated data parsing configurations over databases. Simple, native synchronization hooks. Troubleshooting Common Implementation Errors
// Simplified pseudocode of the core logic found in io.horizon.tictactoe.aix
: The extension includes a local artificial intelligence module with selectable difficulty configurations (such as Noob , Medium , and Pro ). This handles single-player logic entirely on the device without requiring external APIs or web requests.
: The package monitors cell inputs instantly, matching matrix selections against winning axis lines to automatically fire win, loss, or draw alert callbacks.
: Automatically determines if a player has won or if the game is a draw. Reset Board : Clears all positions for a new game.
: Use styling blocks like SetButtonColor or SetXImage to establish the visual aesthetic of the board tokens. If building a single-player game, add the EnableBot block here.

The aix likely stands for (or Interface). By isolating the logic into its own package, we achieve two things:
For Tic-Tac-Toe, aix likely utilizes full Alpha-Beta Pruning, resulting in an . You cannot win against it; the best you can hope for is a draw.
