I think "ext.mappingsChannel" refers to a potential "ext" property of "minecraft", and that you need to start with the project. Try mappings channel: stuffiesss.ext.mappingsChannel, version: stuffiesss.ext.mappingsVersion

Use a Code block (the <> symbol in the top bar when editing) to preserve formatting.

We need more info to help: where did you place the texture file, what have you tried, are there any errors? Is the problem that the item is black-pink checkered, meaning the texture is missing, or something else?

It's complaining about a missing model file. Can you post a screenshot with the contents of the assets/modded_boss_fight/models folder?

I've just started modding, and I'm trying to make custom swords. When I try to import SwordItem, I get the error: What confuses me is that other item classes work fine: package io.github.xxx.denseswords.item; import io.github.xxx.denseswords.DenseSwords; import net.minecraft.world.item.Item; // works fine import net.minecraft.world.item.ShovelItem; // works fine import net.minecraft.world.item.SwordItem; // Error: The import cannot be resolved import net.minecraftforge.registries.DeferredRegister; import net.minecraftforge.registries.RegistryObject; Forge MDK v55.0.15 - Minecraft 1.21.5 Java v24.0.1 Windows 11 IDE: Visual Studio Code
