Without Network protocol fix mod, I get kicked with a Network Protocol error when on LAN. Also, both of these issues are caused by a Null Pointer Exception/Screen cannot be null in a "Client Bound Player Combat Kill Packet". -

You need a new "items" folder at resources/assets/yourmodid/ there you add for every item model a .json file with the exact item/block name and fill it like this if it's an item: { "model": { "type": "minecraft:model", "model": "yourmodid:item/youritem" } } and so if its a block: { "model": { "type": "minecraft:model", "model": "yourmodid:block/youritem" } } There is also a generator for it you can do namy crazy things with it which replaces the previous hard coded Item Properties implementaion method (Bow pulling animation for example). https://misode.github.io/assets/item/ -

Hello! I'm playing a modpack (custom made) with some friends, and we have the server running on BisectHosting. We encountered a bug with an entity from The Box Of Horrors mod, that would crash the game whenever someone nearby it would log in. We tried to fix it by: 1) Editing the player.dat files to change the location of the affected players (something I had done successfully previously) 2) Updating the version of the mod we had (0.0.8.2) to the latest alpha version (0.0.8.3 However, after doing both of those, none of us are able to join the server, and we get the following errors: Server side: https://pastebin.com/J5sc3VQN Client side: Internal Server Error (that's basically all I've gotten) Please help! I've tried restoring the player data to how it was before I made the changes (Bisect allows you to restore deleted files) and deleting all of my player data files and I still get the same error. Deleting Box Of Horrors causes the error: Failed to load datapacks, cannot continue with server load. -

Hey there! I'm trying to create a simple mod for Forge 1.21.1 that adds a few custom banner patterns that don't require any banner pattern items. To be completely honest, this is my first time modding for Minecraft, so after setting up the project in Intellij, I copied the parts of the source code from this mod on CurseForge that dealt with adding and registering banner patterns, including the lang and banner_pattern .json files. From what I understand, to add a banner pattern that doesn't require a banner pattern item, I only needed to create the registries for each pattern like in here and then register it in the main java class like here on Line 54. Additionally, in the lang/en_us.json file, add in the names for each respective banner color, and in the data/minecraft/tags/banner_pattern/no_items_required.json file, add each banner pattern that does not require a banner pattern item to make a banner. The project is able to compile when loading in Forge which makes me assume that the file structure I have is correct, but on loading a Minecraft world, this error appears in console and the loom is subsequently blank. [Worker-Main-1/ERROR] [minecraft/TagLoader]: Couldn't load tag minecraft:no_item_required as it is missing following references: *lists every added entry in no_item_required.json* The message clearly states something went wrong regarding when trying to load in the registries from the mod, but I have no clue what could be wrong with the code I have. Attached below are screenshots of what I currently have. Java Main Class Banner Registry Class File Structure Error in Console upon loading a Minecraft world What the loom shows without minecraft:no_item_required The original mod I copied still functions completely, so if anyone can figure out why the registries for the mod I'm making isn't working, that would be greatly appreciated! -
Please someone help me to know how can I fix this generation error in the trees! I already uninstalled and reinstalled several mods in my modpack and can't figure out what is causing it.
