Copper Bulb Early
简体中文
This is a mod that perfectly backports the Minecraft 1.21.4 Copper Bulb to Minecraft 1.20.1, bringing the complete copper bulb features and advancements back to Minecraft 1.20.1.
Because the mod uses the vanilla namespace and data format, it is compatible with copper bulbs in higher-version schematics loaded by the Litematica mod. Additionally, upgraded worlds can be recognized and preserved by higher versions.
Description
This project is modified from Rczlin-bulb-early-1.20.1
Compared to the original ported mod:
- Fixed issue where copper bulbs could not oxidize due to random tick events
- Fixed resource files to use vanilla namespace for resource pack compatibility
- Added porting of all copper bulb variants
- Added porting of related advancements

Incompatibilities
- BBOR (Bounding Box Outline Reloaded) – This mod has a serious bug that causes abnormal mining time increases for this mod's blocks and may lead to blocks not dropping any items when broken. Since BBOR is no longer maintained, this incompatibility will not be fixed.
Note
- If installed only on the server and not on the client, issues such as “Missing mod” or “Block ID cannot be resolved” may occur when connecting to this server.
- If installed only on the client, you can still join a server that does not have this mod installed (the client-side mod blocks will not take effect on that server).
