Carpet LAB Addition
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Carpet features created for the LAB SMP, as we need them. Currently only contains features for Scarpet.
Scarpet events:
__on_player_message_broadcast(player, message)
- Triggers right before a player message is broadcast to the server.
- Can be cancelled by returning 'cancel', which prevents the message from being sent.
- Useful for making changes to chats before they're sent.
__on_player_edits_sign(player, block)
- Fires after a player edits a sign, after the vanilla text changes take place.
- Can be used to add custom sign formatting.
- Example script
Scarpet functions:
encode_snbt(expr, force?)
- Essentially the same as
encode_nbt(expr, force?), except it allows heterogeneous lists - This is done to bring it in line with vanilla's new NBT format
