This is the program I submitted for my Grade 12 Computer Science final project. It implements a basic Mahjong game with two standout features: 3D rendering and networked multiplayer.

It is written in Java using the LWJGL3 library.

There should be a .jar included with the source code. If not, you can build one with Gradle. Run ./gradlew jar (or if using Windows CMD, gradlew jar). The jar must be executed on the same directory as the assets directory.

You can play multiplayer with another player if they run the game, and you type in their ip address, a colon, then the port number 34567.

The main game class is the MahjongGame class. This MahjongGame class can have up to 4 controllers connected to it, some of which might be controlled by bots or networked players. The MahjongGame server only sends updates to the game state, so clients must maintain their own local copy of the game state.

This is accomplished through the MahjongClientState class, which tracks the all the game state that the client knows. In order to power animations, the client stub also updates the AnimationManager class, which track tile model orientations and animations.
