Contains shared classes used by several of my mods, to make them easier to update and maintain.
Note: Items no longer have NBT in Minecraft 1.21.
The "sl_nbt" command can be used to view the NBT of a block, entity, or item (pre-1.21) in an easy to read format. Unlike the vanilla "data get" command, this opens a new UI and formats the text for easy reading. The output is also color-coded, and 32-bit integers are displayed in both decimal and hexadecimal. From there, you can also export the NBT to a JSON file (possibly useful when reporting bugs).

May or may not be up-to-date (updated 2021-04-24). I release new mods occasionally. But I'll try to keep this updated. Some of my mods do not use Silent Lib, mostly smaller mods that add no blocks or items.
Make sure Silent Lib and all mods that depend on it are up-to-date first. Mismatched versions are a common cause of crashes. If updating does not help, report it on the issue tracker of the mod that seems to be at fault. Usually the other mod is responsible. I may have forgotten to publish an update.
The files are still there, but they are appropriately hidden from the main page. Go to the "Files" tab, click "View All," then select the ancient game version that you for some reason have a desire to play. Research project for your history class or something?
