Forgive me if I'm missing something simple, I'm new to writing mods for Minecraft. In fact this problem is from me following this tutorial.

Apparently I'm missing a file even though I'm pretty sure I'm pointing to it, and the file does exist in the workspace.

Here is my error:

tutorial_item.json

{

    "textures": {
        "layer0":"tutorial:items/tutorial_item"
    }
}

And attached is a picture of my workspace

READ your error.

 

Caused by: java.io.FileNotFoundException: tutorial:models/item/tutorial_item.json

I'm no expert, but the directories given in your item json do not correspond with the ones in your mods assets folder.

An e.g. where it says 

tutorial:items/tutorial_item

the mod is looking for a folder called assets.tutorial.items.tutorial_item

 

I highly recommend you familiarize yourself with the java and json before attempting this. It'll make the process much smoother.

Thanks everyone! I didn't realize "tutorial" was pointing towards a folder/package, I thought it was using the modid I had set.

Sorry it took me so long to reply, I went to bed right after posting this.

Well, rather, your modID isn't set. You may have given your code a package name, but your mod ID is still "tutorial."
