Card Game - Knee Grow

Overview

Knee Grow is a turn-based card game implemented in Java with a JavaFX interface and a Maven build. Players draw and play cards, manage a field and shop, and compete by their accumulated Gulden score. The game logic keeps track of the current player, turn progression, and the score comparison at the end of a game.

Game model

The model separates card data and behavior from players and the interface. A Player owns a deck, six active-card slots, and a field, while the GameMaster coordinates the players and turn state. The card package distinguishes card types and uses a Harvestable interface for cards that can be placed on a field. A shared Shop holds product quantities and prices, and configuration data is accessed separately from the screen controllers.

       Data and save loaders

The repository also separates loading and saving from the game model, with data-loader and plugin classes for external card configuration formats. The Shop uses a shared singleton instance, while controllers handle the JavaFX screens and actions.

What I learned

This project was a practical exercise in modeling game state with collaborating classes rather than keeping all rules in the UI. It helped me understand how interfaces, class hierarchies, persistent game data, and turn-based state fit together in a desktop application. The class diagram shows the main model relationships.
