Planet

A C++ game engine

Planet started as just a 2D hex and square grid infinite map implementation. Both make use of a chunking system that aggregates the allocation of larger parts of the map which are created lazily as required by the game.

Now it consists of several libraries:

• planet (this library) -- General game code. Includes 2d and 3d affine transforms, sound, UI, serialisation, an ECS, and more.
• planet-sdl -- Wrapper for use of SDL2 C library with the rest of the Planet engine.
• planet-vk -- Wrappers for the Vulkan C library with higher level engine code.
• planet-android -- Android specific code needed to interface between Planet, SDL2 and the platform.

Building and running the library and examples

git clone --recursive git@github.com:KayEss/planet.git
cd planet
mkdir build.tmp
cd build.tmp
cmake ..
make
./examples/snake

Development requirements

On Linux you'll need some dev packages installed:

sudo apt install libasound2-dev libogg-dev libopus-dev liburing-dev libvorbis-dev

On Windows it's generally best to add these as submodules to your project and use add_subdirectory from cmake to build them.

Modules

An incomplete list of the available modules are:

• Behaviours -- unstable
• Serialisation -- stable
