(Newbie question) How do I add a basic texture?

[T-Dark]

Hello all,

 

I'm currently trying to add my very first block, with a basic 16x16 texture, the same on all sides.

However, despite the fact that both a furnace.json and a furnace.png files exist, I continue to get the following error message

The json file is

Spoiler

{
  "forge_marker": 1,
  "defaults": {
    "model": "testmod:furnace"
  },
  "variants": {
    "normal": [{}],
    "inventory": [{}]
  }
}

and the png is attached

 

My Eclipse project configuration is attached. What am I doing wrong? Is more information required?

 

(Unfortunately, I have zero idea about how github works, so my project can't be found there)

You told the game to look for a model:

3 hours ago, T-Dark said:

    "model": "testmod:furnace"

It doesn't exist. 

[T-Dark]

Could you elaborate on that a little bit more? Should I have spelled the json as "models"? Do I need to add some other file containing model information?

 

I'm not telling the game anything about looking for a model: I just registered the block and the ItemBlock. Do I need to do something else that I'm missing?

Fixed typos

[Draco18s]

Blocks are comprised of 3 things:

 

1) A blockstate file that tells the game how to translate a block state (the metadata equivalence) into a model

2) A model file that tells the game what shape the block has (stairs are not cubes!) and what texture is on each face.

3) One or more texture files.

 

If you want your block to be a full cube (like dirt or stone) then you probably want to use "model": "cube_all" instead. Additionally you will need to specify textures, "textures": { "all" : "<your texture>" }

Edited February 14, 2019 by Draco18s

[T-Dark]

So the json should look like this?

 

Spoiler

{
  "forge_marker": 1,
  "defaults": {
    "model": "cube_all",
    "textures":
    {
        "all": "testmod.textures.blocks/furnace"
      },
  "variants": {
    "normal": [{}],
    "inventory": [{}]
  }
}

 

Because it still gives an error message

Caused by: java.io.FileNotFoundException: testmod:blockstates/furnace.json

As if it couldn't find the json file itself.

 

 

Actually, here's the whole stacktrace, in case it's useful

Here are some examples of block json files:

 

Block Json File| Folder :  testmod/models/block (NAMED furnace.json)

Spoiler

{
   "parent": "block/cube_all",
   "textures": {
       "all": "testmod:blocks/furnace"
   }
}

 

 

Item Json File| Folder : testmod/models/item(NAMED furnace.json)

Spoiler

{
   "parent": "testblock:block/furnace"
}

 

 

Blockstate Json File| Folder :  testmod/blockstates(NAMED furnace.json)

Spoiler

{
    "variants": {
        "normal": { "model": "testmod:furnace" }
    }
}

 

 

[T-Dark]

Should I replace the entire json with just that? Because that still doesn't work

This is a basic example, but it works for me.

[T-Dark]

Yup, replacing everything does not solve the problem.

 

The full paths are "src/main/resources/asset/testmod/blockstates/furnace.json" and "src/main/resources/asset/testmod/models/item/furnace.json" (or .../models/block/furnace.json)

 

Error message as follows

It looks like it can't even find the files, regardless of actual content. In fact, I tried removing the whole asset package (and subpackages). Nothing changed in the error message.

Yes. You are missing a model file.

nov4e had given you a good example model json. You might want to use them for now.

 

You need to have a furnace.json in your testmod/models/block/.

You need to have a furnace.json in your testmod/blockstates/.

You need to have a furnace texture in your testmod/textures/blocks/.

 

The error is saying that Minecraft cannot find your furnace.json in your testmod/models/block/.

Yeah, but, as far as I can see, I do have it there.

 

 

I'm using nov4e's jsons, unedited. The texture is a 16x16 pixels png made in paint.net. The error is the same. it can't find testmod:models/item/furnace.json and testmod:blockstates/furnace.json (in this order) even though they clearly exists.

No they don't. Check your spelling. You named your assets folder "asset".

 

Minecraft is looking for assets/testmod/*, which does not exist in your mod directory due to the misspelling of the "assets" folder.

Oh! Thanks! Unfortunately, renaming the package does not fix the problem.

 

testmod:models/item/furnace.json and testmod:blockstates/furnace.json are still not found.

 

Sorry to take your time for what probably is a mispell on my part.

[DavidM]

Hmm... try right-clicking on your project folder and click "Refresh", then launch the game again.

 

Might not be the problem but worth a try.

Nope, the refresh did nothing to the game. it also messed up the folder structure

 

Since we are talking about eclipse, is it in any way helpful if I say that sometimes eclipse shows a nullPointerException error message when I close a tab?

[DavidM]

According to your last screenshot, you are in the "bin" folder. You need to go back to your "src" folder.

 

Apart from that, I can't figure out what went wrong. Check all your spellings and your ModelRegistry.

[T-Dark]

My spellings seem to be ok. That being said, what is the ModelRegistry? Is it the GameRegistry.ObjectHolder annotation? What should I be checking exactly?

 

Here is the annotation

Spoiler

package main.java.tdark.testmod.blocks;

import net.minecraftforge.fml.common.registry.GameRegistry;

public class ModBlocks
{
    @GameRegistry.ObjectHolder("testmod:furnace")
    public static BlockFurnace blockFurnace;
}

 

And here is the block class

Spoiler

package main.java.tdark.testmod.blocks;

import main.java.tdark.testmod.TestMod;
import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
import net.minecraft.util.ResourceLocation;

public class BlockFurnace extends Block
{
    
    public static final ResourceLocation FURNACE = new ResourceLocation(TestMod.MODID, "furnace");

    public BlockFurnace() {
        super(Material.IRON);
        setRegistryName(FURNACE);
        setUnlocalizedName(TestMod.MODID + ".furnace");
        setHarvestLevel("pickaxe", 2);
        setCreativeTab(TestMod.creativeTab);
        
    }

}

 

 

 

Finally, does it help to know that I wrote this by following McJty's video tutorials?

There's a dot there.

That's wrong.

If you're trying to do "modid:block" you failed, because that's a colon.

This is why I don't suggest that people construct their registry names themselves, but let the game do it.

Edited February 15, 2019 by Draco18s

[T-Dark]

Thank you very much. The question now is: What do I need to do to let the game construct it's own registry name?

Sorry for the stupid question, but I literally know nothing about Forge, and I'm having a hard time understanding the docs.

[Draco18s]

Option A: dont pass your mod id

Option B: use the version that takes 2 strings

[T-Dark]

Ok, I'm now using the version that takes 2 strings. Still no success. The Item json and the blockstate json are not found, and I'm getting a net.minecraft.client.renderer.block.model.ModelBlockDefinition$MissingVariantException.

    {
        event.getRegistry().register(new ItemBlock(ModBlocks.blockFurnace).setRegistryName(TestMod.MODID,"furnace"));
    }
}

 

 

This is all I can find that has anything to do with the block. Still no success.

[T-Dark]

In other words, I should move all the code in CommonProxy to TestMod, and register the item form of the block with that? How do I use that thing?

[T-Dark]

Thank you very much, I'll try to understand the setCustomModelResourceLocation thing later. Sorry, I still have no idea what a ModelResourceLocation actually is, but I guess I'll figure that out.

 

That aside (for now), what about the missing blockstate json (which, as far as I can see, is not missing, so I've no idea what is going wrong) and the ModelBlockDefinition$MissingVariantException? What could be causing them? As far as I understand, block models should get automatically registered along with the block itself, via the default IStateMapper. What am I missing?

A ResourceLocation is a location for a resource (i.e. a model.json, a texture, etc). It's a convenient way for you as a modder to say "go look here" without having to understand where "here" actually is (because resource packs will override the default assets you ship and you shouldn't know or even care that this has been done!)

 

A ModelResourceLocation is specifically a ResourceLocation that points to a model file. As far as you're concerned, its just a resource location that points to a file in a slightly different place (you still need to supply the target file and that file will be in a subfolder named "model" or "models,"¹ but otherwise it doesn't change how you use it in the code.

 

The two pieces of information a resource location needs in order to find an asset are two things:

1. Domain

2. File name

 

The domain is the same as your mod ID. This tells the game "don't look in the vanilla assets folder, look in the a folder named <modid>. You can specify domains that aren't your mod ID, as well. For example, if you want to create an item that looks like an apple, you can specify the domain "minecraft" and you can use vanilla texture files even if a custom resource pack has been installed that only alters vanilla textures.

 

The file name is essentially which asset to load. e.g. "apple". Typically you'll name your asset files for the block or item that they are for, but you don't have to (it just makes everyone's life easier). This file then must exist in the domain that was specified, if it doesn't, you'll get a MissingVariantException of one form or another.

 

And I say "one form or another" because it's an error caused by another error. If the game goes to load the asset you told it to and it isn't there, the FileNotFoundException will be thrown. But because the game is trying to build models, the model fails to get built, and that throws another error. If you told the game that your block has several states and then don't list one of them in your blockstate.json file, well, that's a MissingVariantException. If you included it in the blockstate file, but pointed to a model that fails to load because it existed, but had an error in it, that's a MissingVariantException Caused By MalformedJSONException.

 

And so on.

 

Any time you see "MissingVariantException" and a stack trace, keep scrolling down to the next error, it'll almost always start with "Caused By" and another error type. That error is the one you need to fix.

 

For example, lets take the log in your original post:

 

[12:34:06] [main/ERROR] [FML]: Exception loading model for variant testmod:furnace#inventory for item "testmod:furnace", normal location exception:

The three highlighted sections tell us everything: 1) the problem item or block, 2) the underlying error and 3) what file the game was trying to read.

 

These will vary slightly depending on exactly what error is the one that needs to get fixed, but this is what to look for.

 

1. _{I believe that it was originally "models" and that Mojang removed all the lingering s's, so this will vary slightly by MC version.}
