⚔️🖥️ Battle Coder 🎮

A 2D vectorial game and scripting app to teach programming.

Written in C++ 20 and powered by embedded Python 3 scripting, Battle Coder turns first-year computing lessons into fast-paced coding duels. Students tackle level-based challenges by writing Python that directly manipulates game objects and logic.

Thanks to Pybind11, key C++ classes, functions and entities are surfaced to Python, delivering a smooth bridge between native gameplay and user scripts. Progression, scores and content drops are delivered via Firebase (JSON), giving lecturers live oversight and automated grading.

Our goal: an engaging educational tool that motivates learning through gameplay, scoring, and automated code tests.

Features

🐍🖥️

Embedded Python Scripting

Players write and execute Python code that manipulates game objects and mechanics in real time.

🧩🎯

Interactive Coding Challenges

Fun, competitive puzzles designed to teach core programming concepts.

☁️📊

Firebase Backend & Progress Management

Remote storage for levels, student progress and leaderboards, all in JSON.

👩‍🏫📝

Lecturer Controls

Content release, automated exercises and detailed analytics to monitor and motivate learners.

🖼️📋

Raylib User Interface

Custom raylib-based UI for login, registration and scoreboard display, keeping the experience smooth and consistent.

My Role in the Project

🐍🖥️

Python Scripting

Designed and built the scripting core system that lets students write, "compile" and run Python code in-game, handling parsing, execution and game-side callbacks.

🔗🧩

Pybind11 Integration

Exposed essential C++ functions, methods and game objects to Python via Pybind11, enabling seamless interaction between native code and scripts.

🖥️⌨️

Script Editor UI

Built an in-game ImGui editor with save, compile, run and stop controls. Includes a status indicator: 🔴 Error
🟡 IDLE
🟢 Running

⚠️💡⏳

Error Handling & User Feedback

Implemented real-time error detection with highlighting and feedback. Added safeguards to prevent hangs and crashes like infinite loops (while, for) during script execution.

📐✏️

Vector Shape Editor

Built an in-game editor inspired by GeoGebra, allowing users to ➕ add, ❌ remove, and 👆 drag points to build custom vector shapes used alongside default game figures.
