This is an ongoing project to create a 2D game engine with PixiJS using Typescript. The initial purpose is to develop a simple engine that my CART students can build on. My goals are to introduce them to MVC with how the UI is organized, and ECS with how the gameplay code is organized. It's also a playground for me to deepen my skills as time allows. As of this initial commit, the code is likely still mixing design patterns, and there is more commenting to be done. These are tasks I would like to perform with students. Progress will happen in occasional bursts. As of right now there isn't an objective, but there is collision, environment navigation, and intractable objects demonstrated in the initial release.
