2D Physics Engine

A lightweight 2D physics engine built with C++20 and SDL2, focusing on custom collision detection via the Separating Axis Theorem (SAT).

🚀 Quick Start

1. Open the Developer Command Prompt for VS.
2. Run build.bat to compile the engine and sync assets.
3. Run .\build\Game.exe to start the application.
4. Use test.bat to run the automated test suite.

📂 Project Structure

• assets/: Game data, fonts, and textures.
• code/: All source code (.cpp, .h).
• misc/: Debugger configurations.
• notes/: Development logs and performance improvements.
• third_party/: External dependencies (SDL2, OpenGL).

🛠 Script Reference

Script	Purpose
build.bat	Compiles the project, generates unique PDBs, and mirrors assets to the build folder.
debug.bat	Launches the executable using the raddbg debugger.
test.bat	Compiles and executes all_tests.cpp.
todo.bat	Lists all // TODO: comments across the source code.

🏗 Technical Details

• Compiler Flags: -std:c++20 -W4 -WX (strict warnings as errors).
• Debug Features: Randomized PDB naming to allow building while the debugger is attached.
• Physics: Supports Circle-Circle, Box-Box, and Circle-Box collision detection and resolution.
