CardEngine
by _dynobot
CardEngine is a Forge library for building card-drafting systems that give players custom upgrades.
What it does
The library handles capability storage, client and server synchronization, and the rendering of overlays and a card drafting screen. A developer registers cards and binds mechanisms to them, and networking and rendering are handled automatically. Annotated fields can be exported as editable JSON configs and reloaded live in the UI. A server running it needs every connecting player to have it too. Builds cover 1.20.1 – 1.20.6 on Forge, with 1.0.2 for 1.20.1 as the latest file, and the code is released under All rights reserved, not as open source.
