Cross Platform Game Engine

• Cross-platform rendering backend, supporting both OpenGL and WebGPU
• Entity-component system (ECS) based scene model, backed by Entt
• Editor with a content browser, scene viewport, and asset pipeline (textures, meshes, materials, tilesets, audio)
• 2D and 3D rendering, including sprites, text (MSDF font atlases), and static meshes
• Built-in 2D physics via LiquidFun/Box2D
• Lua scripting support
• Scene and asset serialization

Ensure you have these installed:

• A C++17 compiler (MSVC, Clang, or GCC)
• CMake 3.10 or newer

⚠️ Warning: This repository uses Git submodules. When cloning, make sure to use the --recursive flag:

git clone --recursive https://github.com/ThomasJowett/Cross-Platform-Game-Engine

If you've already cloned without --recursive, initialize the submodules afterwards with:

git submodule update --init --recursive

Windows: Use CMake to generate Visual Studio project files, then build the Editor or Runtime target.

Mac: Use CMake to generate Xcode project files or Makefiles.

Linux: First install dependencies:

sudo apt-get install -y libx11-dev libxrandr-dev libxi-dev libxinerama-dev libgl1-mesa-dev libxcursor-dev mesa-common-dev g++ make

Then use CMake to generate Makefiles and build with make.

Once built, run the Editor executable to open the editor.

Runtime doesn't open a project directly — it plays back an already-exported game (see Exporting a game). To try a project standalone, export it first (File > Export Game in the Editor, or headlessly with Editor <project>.proj --export-game <output-path>), then run the resulting executable/app bundle.
