: Player B’s device listens to the Firebase path using a DataChanged block.
: You can modify the appearance of the board directly in the Java source if you are an advanced user, such as changing drawX and drawO colors or line widths. Game Logic Blocks :
You can find documentation, updates, and the download link on the MIT App Inventor Community Niotron Community io.horizon.tictactoe.aix
: App Inventor pushes this raw index to a specific path in Firebase (e.g., Rooms/Room_ID/LatestMove ).
: Use the extension’s "On Click" or "Move" blocks to update the internal game state. : Player B’s device listens to the Firebase
The extension isn't just a black box; it's a customizable component with a range of features accessible through its and Blocks in App Inventor.
Instead of forcing developers to build complex logical systems using hundreds of native visual blocks to handle grid structures, turn validations, and win-checking algorithms, this extension packs the entire logic of a Tic-Tac-Toe engine into a single, compact file. What is io.horizon.tictactoe.aix ? : Use the extension’s "On Click" or "Move"
In block-based app builders, an is a packaged Java file used to add custom functionalities not natively provided by the basic palette. The io.horizon.tictactoe.aix package handles the back-end calculations of a standard Tic Tac Toe match.
Blocks designed to sync moves across devices for online play.
: Use the extension’s events (like onWin or onDraw ) to trigger victory animations or reset buttons. Pro Tip for Designers 💡
