Subsystems

Pie Noon code is divided into the following subsystems

PieNoonGame – holds game subsystems, state, and state machine
Engine – a simple, game agnostic renderer, file loader, and input system
GUI – a simple, game agnostic GUI

Pie Noon is built on top of SDL, a low-level cross platform library. SDL abstracts input, file loading, threading, system events, logging, and other systems from the underlying operating system. In addition, Pie Noon utilizes FlatBuffers for serialization, Motive for animation, and PinDrop for audio.
