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?

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/

Hey! I noticed you're trying to register your alexandrite item and possibly set its resource location manually with setId(...). I wanted to help clarify a few things that might simplify your code and avoid errors.

✅ The issue:

You're using setId(...) inside the item registration like this:

 

public static final RegistryObject<Item> ALEXANDRITE = ITEMS.register("alexandrite", () -> new Item(new Item.Properties().useItemDescriptionPrefix() .setId(ResourceKey.create(Registries.ITEM, ResourceLocation.fromNamespaceAndPath(TutorialMod.MOD_ID, "alexandrite")))));

But:

Item.Properties does not have a setId(...) method — this line will either fail or do nothing meaningful.

useItemDescriptionPrefix() is mostly used for translation keys (like "item.modid.name") but isn't needed unless you have a very specific reason.

🛠 The fix:

You only need to register your item like this:

 

public static final RegistryObject<Item> ALEXANDRITE = ITEMS.register("alexandrite", () -> new Item(new Item.Properties()));

Forge automatically handles the ResourceLocation (modid:alexandrite) based on the name passed into .register(...), so there’s no need to manually assign it.

📝 For the texture:

Make sure you have this file in your resources:

src/main/resources/assets/tutorialmod/models/item/alexandrite.json

{ "parent": "item/generated", "textures": { "layer0": "tutorialmod:item/alexandrite" } }

And your texture PNG goes here:

src/main/resources/assets/tutorialmod/textures/item/alexandrite.png

🌍 For the name in-game:

Add this to your en_us.json under:

src/main/resources/assets/tutorialmod/lang/en_us.json

{ "item.tutorialmod.alexandrite": "Alexandrite" }

 

Note: if im wrong about the issues you are encountering, i apologize.
