What's inside
README
Why Nevermore?
Code in Nevermore has powered over a billion play sessions on Roblox. Nevermore is used in all Studio Koi Koi games, as well as many other games on Roblox.
Install using npm
Nevermore is designed to use npm or pnpm to manage packages. You can install a package like this.
npm install @quenty/maid
Each package is designed to be synced into Roblox using rojo.
See the installation guide for more details.
Install by copy-and-paste
You can also copy and paste a lot of these libraries into module scripts and with small refactors, have them running anywhere. The closer the package gets to a full-sized gameplay feature (such as Ik), the less likely this is going to be ergonomic.
Packages
There are some packages this repository is known for containing, and have had significant cultural impact on Roblox.
- Maid - Utility object to clean up connections
- Rx - Reactive programming implementation
- Binder - Bind Roblox objects and instances
- Spring and AccelTween - Animation objects
- Signal - Signal implementation
- Promise - Promise implementation on Roblox
- Octree - Spatial data structure that helps with performance
- Blend - Declarative UI framework that makes animations and state-management easy
- DataStore - Battle-tested datastore wrapper
- Camera - Layered camera system that interops with Roblox's cameras
Many of these packages represent not just useful code, but useful patterns, or ways of thinking about programming on Roblox.
