Blockstates Property for a Block

[Siqhter]

I have read past forum posts addressing this, but I still can't seem to figure it out. I have a block that should create a variant for each EnumDyeColor. (So, 16 altogether.) I have already gotten this same block to work using a "facing" property so that it faces the player when placed, but I can't seem to get the "color" property to work. It generates 16 items without textures in the inventory and without textures when placed. I am pretty sure it's a JSON thing, because of the error which I will post below. Thanks.

Exception loading model for variant test_block#color=6,facing=east for blockstate "test_block"

The console also says "suppressed 59 additional model loading errors."

Here is my JSON file.

And just to clarify, the block model is loading a "test_block" in, just not generating the blockstate variants for the other 16 colors.

[Draco18s]

You can't have that many states.  IBlockState is still baked by a 1 nibble (half byte) metadata that can hold only 16 values.

I'm wondering how this guy did it. https://github.com/MrCrayfish/MrCrayfishFurnitureMod/blob/master/src/main/resources/assets/cfm/blockstates/counter.json

He uses this for multiple different blocks for different color variants.

[Cadiboo]

You can have UnlistedProperties, or create a new block for every color. I recommend the 2nd one

Unlisted properties aren't used to determine which model to render for a block, they're used by custom block models to determine how they should render. The correct solution here (while keeping a single block) would be to store the extra data in a TileEntity and use regular properties that have their values set in Block#getActualState. Though Mojang is moving away from having a single block for all colours with The Flattening in 1.13, so it may be best to split the colours into separate blocks now (as Cadiboo suggested).

 

I have an example of a block with a colour and a facing here: Block, TileEntity, blockstates file

[Siqhter]

Can you explain what writeToNBT and readFromNBT are?

[Cadiboo]

Write to NBT - write your data to a NBTTagCompound for serialisation (saving)

Read from NBT - read your data from a NBTTagCompound for deserialisation (loading)

Huh, I looked through that, and my JSON file is formatted the same way, but it gives me an Exception loading model for variant error. I made sure to register the tileentity, but maybe I'm missing something else with the actual model?

[Siqhter]

Nevermind, I was able to get it working. However, using the getSubBlocks method, the textures for all other 15 blocks are not registering.

[Cadiboo]

Show your new code? Preferably as a GitHub repository 

[Siqhter]

Yeah, I've been getting a repository set up. For now, I'll just post the code directly.

These are the two java classes for the Block itself, and then the TileEntity.

Still stuck on this, I thought I figured out but the proper textures for each blockstate were not rendering properly. Just seeing if anyone has any ideas. Thanks.

[V0idWa1k3r]

Did you set up your repository? We would need to look at your code and the blockstates/model file to see what's wrong.

[Siqhter]

I've been having issues with the repo right now. I duplicated some files accidentally, and some of the old files are still in it. Here is the blockstate and model file. The java classes are the ones posted above. Thanks.

You are not including the color in your state here.

What is your issue? Are item textures not there? Or those of blocks? If it's blocks then see above, otherwise you need to show how you are registering models for your itemblocks.

Ok, so would I return COLOR and  FACING? Because right now it gives an error if I pass in COLOR.

Yes.

What is the mysterious "it"? The compiler? The IDE? The game? If it's the first two then you should be able to fix it, since it's just a compile error and those are easily fixable with some java knowledge. If it's the latter then post the error log.

[Siqhter]

Sorry, I meant the IDE, as in the red underline. It still compiles. The only error I get is "withProperty()" in IBlockState cannot be applied  to: IProperty<T> COLOR (EnumDyeColor)".

[V0idWa1k3r]

It can't because you have a syntax error that you've posted.

From the looks of the error you are passing wrong arguments to the method. See the method parameters and pass what it wants.

[Siqhter]

Well, this is what it says it expects in the error: block.properties.IProperty<T>.  But I don't think I really understand what it actually wants, other than COLOR, or rather what I'd pass in.

[Siqhter]

I assume just the method?

Ok, but I'm still not sure what it wants me to pass in in addition to COLOR property.

[Siqhter]

So specify the color, with maybe, "dyeColor.get()"? I don't know what else to use.

You need to fetch the color stored in your TE, since you can't store enough in the metadata.

Ok thanks. I was a little unclear because I thought I was only supposed to store FACING properties in the TE. This makes sense now.
