Hoshiko

University of Puget Sound Computer Science Capstone Project

A game using Unreal Engine 4 that taught basic programming concepts in a visual way by having the player enter code into in-game computer terminals
Each in-game computer terminal had an embedded Python subinterpreter thread with APIs for controlling game mechanics (for example, typing door.open() would open a door connected to that terminal)
The in-game code editing UI was powered by Chromium Embedded Framework
