HypeHype was a mobile-first game creation, publishing, and playing platform. It had an in-app game editor where you could make logic using visual programming and use lots of provided 3D models, audio, and other game assets. After publishing your game, players could instantly play it with some multiplayer features out of the box.

I worked at HypeHype initially as a backend and machine learning engineer but later moved mostly to the engine side due to my personal interests! Regarding backend and AI, I made the semantic search for the 3D assets to improve the asset search experience for the users. It enabled the users to search in any language and also search based on the visuals of the assets. I, with my colleague, also worked on the backend for the scene generation feature we had where te users could generate scenes by giving a prompt. On the engine side, I worked on the editor side, implementing new nodes and making game creation easier and more straightforward for the creators. One of the nodes that I worked on a lot was the Container node which allowed for grouping and reusing logic (nodes) in 4 ways:

1. Basic grouping of logic nodes for better organization
2. Reusables which worked like prefabs in other engines
3. Addons which are like Component in Unity that you can attach on objects
4. Functions which had two modes: local and global. Local functions were like class instances in any programming language and globals were like singletons. (I know the name function was a bad decision for these!)

Another one of the nodes was the AI node which allowed for calling an LLM in the game and receiving structured data or playing AI-generated voice in games.

I also led the effort of adding support for Luau scripting to allow creators to use Luau to make logic instead of visual programming, because visual programming can get a bit messy as you can see in some of the screenshots later here! Here are some of the docs of the api: Entity, Component, Core, Player.

The Luau code could run both on the clients and the server. Running them on the server-side enabled games to have new multiplayer features (Game modes) and made the client ↔ server communication easier (Signals). We also worked on enabling AI to write and execute code while the game is published and running (not just in editor). The following is a recoding of a small demo of that where you can also see some of the code the AI generated to run inside our engine:
