2D Game Engine

A lightweight 2D game engine focused on data-oriented design, with a custom Entity-Component-System (ECS), SDL rendering, asset management, and planned embedded Lua scripting.

Warning

This software is still a work in progress and is actively being developed.

Features

• ECS core: simple, cache-friendly component storage and system scheduling
• Rendering: 2D renderer (SDL)
• Assets: texture loading, level data, and resource lifetime management
• Utilities: input handling, timing, logging
• C++23: making use of modern language features whenever possible

Tech

• C++23, SDL2
• Makefile-based build

Getting Started

Prerequisites

• C++ compiler with C++23 support (clang++ or g++)
• SDL2 development libraries
• Lua (e.g., Lua 5.4)
• Make

On macOS (Homebrew):

brew install sdl2 lua
