It's a library for creating server side content, that work for player's without mods or (required) resource packs!
You can create blocks, items and entities, that not only will work fully server side (and singleplayer), but also
are still real custom ones, allowing for better integration with data packs and other mods (servers still see it as
mymod:custom and not minecraft:player_head, unlike bukkit/spigot ones, that only emulate them).
This library also works correctly with other, non-polymer mods and PolyMc!
This library/mod includes few small utilities that can be useful for playing on servers using Polymer.
Few things it does on the client:
- Added compatibility for multiple client side mods (EMI, Just Enough Items, Roughly Enough Items, WTHIT, Jade, AppleSkin)
- Correct information on F3 debug screen
- Full support for Polymer quick block picking (middle mouse click)
- Creative item tabs synced with server
- Fixes (some) server resource pack features broken by Canvas or Iris (custom armor texutes)
Any mod using this library shouldn't be required on the client side! However, as stated above, there are few small quality of life things added with it. So you might want to recommend it or include with your mod pack.
If you have a server and polymer based mods you are using include a resource pack, you might want to install "bundled/packed/all" version of polymer contains AutoHost module, allowing you to set up automatic building and sending of packs to clients.
If you use 1.18.x or older, use this instead: https://github.com/aws404/polypack-host
All information about usage can be found at https://polymer.pb4.eu!
This mod doesn't convert existing mods to server side ones. While it's possible to do so with manual coding, for that you might want to use PolyMc as long as you don't need to use regular mods on the client (for example with a modpack).
