Convert C++ Same Game to Java with Swing GUI

[Copilot]

Direct conversion of C++ Same Game implementation to Java, replacing SDL2 with Swing while preserving all game logic and algorithms.

Implementation

Core Logic (4 files)

• Node.java - Graph node structure (from SameGame.h)
• SameGame.java - Game logic: BFS cluster detection, gravity system, greedy AI (from SameGame.cpp)
• SameGameGUI.java - Swing GUI with mouse interaction (from main.cpp)
• TestGraph.java - Full test suite (from test_graph.cpp)

Technology Mappings

• SDL2 → Java Swing/AWT (no external dependencies)
• vector<T> → ArrayList<T>
• unordered_map<K,V> → HashMap<K,V>
• queue<T> → LinkedList<T>
• Custom Pair<F,S> and ClusterInfo classes replace C++ tuples

Build System

• Maven configuration (pom.xml) for compilation and JAR creation
• Run scripts (run_java.sh, run_java.bat) for convenience
• Updated .gitignore for Java artifacts

Example Usage

// Initialize game with 6x8 grid
char[][] grid = generateRandomGrid(6, 8);
SameGame game = new SameGame(grid);

// Find and execute best computer move
Pair<Integer, Integer> move = game.getBestMove();
game.removeCluster(move.getFirst(), move.getSecond());

Documentation

• README.md - Overview of both versions
• BUILD_JAVA.md - Java build instructions
• CONVERSION_GUIDE.md - Detailed C++ to Java mappings
• README_JAVA.md - Java-specific guide

All 10 tests pass. Both C++ and Java versions coexist with identical functionality.

Original prompt

Start implementation

The user has attached the following file paths as relevant context:

• .github\copilot-instructions.md

[Chronological Review: The conversation began with the user requesting to convert an entire project from C++ to Java, including the GUI, without altering the code. The user emphasized the need for a straightforward conversion rather than a rewrite or modification of the existing logic.]

[Intent Mapping: The explicit user request was to "convert this whole project from c++ to java, the GUI also. dont change the code just convert from c++ to java." The user is looking for a direct translation of the codebase from one programming language to another.]

[Technical Inventory: The primary technologies involved are C++ and Java, with a focus on GUI components that need to be translated. No specific frameworks or libraries were mentioned in the conversation.]

[Code Archaeology: No specific files or code segments were discussed or modified yet, as the conversation is in the initial request phase.]

[Progress Assessment: The request for conversion has been made, but no actions have been taken yet to begin the conversion process.]

[Context Validation: The user’s request for a direct conversion from C++ to Java is clear and requires attention to both the code and GUI components.]

[Recent Commands Analysis: The user attached the tool "semantic_search" to the message, but no specific commands were executed or results returned from this tool yet. The agent was preparing to address the user's request for conversion when the token budget was exceeded.]

1. Conversation Overview: - Primary Objectives: The user requested to "convert this whole project from c++ to java, the GUI also. dont change the code just convert from c++ to java." - Session Context: The conversation is focused on the user's need for a straightforward conversion of a project from C++ to Java, including the GUI. - User Intent Evolution: The user's intent has remained consistent, emphasizing a direct conversion without code alteration.

2. Technical Foundation:

• C++: The original programming language of the project.
• Java: The target programming language for the conversion.
• GUI: The graphical user interface components that also need to be converted.

3. Codebase Status:

• No specific files or code segments have been discussed or modified yet, as the conversation is still in the initial request phase.

4. Problem Resolution:

• Issues Encountered: None reported yet, as the conversation is in the request phase.
• Solutions Implemented: No solutions have been implemented yet.
• Debugging Context: No debugging efforts have been initiated.
• Lessons Learned: No insights have been discovered yet.

5. Progress Tracking:

• Completed Tasks: The user has made a request for conversion.
• Partially Complete Work: No tasks are currently in progress.
• Validated Outcomes: No features or code have been confirmed working through testing.

6. Active Work State:

• Current Focus: The agent was preparing to address the user's request for conversion from C++ to Java.
• Recent Context: The user reiterated their request for a direct conversion without code changes.
• Working Code: No specific code snippets have been discussed yet.
• Immediate Context: The user is seeking assistance with converting their project from C++ to Java.

7. Recent Operations:

• Last Agent Commands: The user attached the "semantic_search" tool but did not execute any specific commands.
• Tool Results Summary: No results were returned from the tool as no commands were executed.
• Pre-Summary State: The agent was actively preparing to assist with the conversion request when the token budget was exceeded.
• Operation Context: The attachment of the "semantic_search" tool indicates the user may be looking for additional resources or information related to the conversion process.

8. Continuation Plan:

• [Pending Task 1]: Begin the conversion process from C++ to Java as per the user's request.
• [Pending Task 2]: Assess the structure of the existing C++ codebase to determine the best approach for conversion.
• [Priority Information]: The conversion of the GUI components is a critical part of the task.
• [Next Action]: Initiate the conversion process with a focus on maintaining the original logic and structure of the C++ code.
