Blockstates Property for a Block

[Choonster]

If you're following my example, the COLOR property is stored in the metadata and as such is already set when Block#getActualState is called. The FACING property is stored in the TileEntity and is the only property that needs to be set in your override of Block#getActualState.

That's exactly what I thought. I'm assuming my problem is elsewhere then? I wasn't sure if maybe it's in onBlockPlaced or something.

What exactly is your current issue? Please post your latest code (or a link to your repository). If it's a model issue, please post your blockstates/model files and your debug.log.

(Note that you can do it the other way too: store the facing in the metadata and the color in the TE).

On placing the block, it should be 1 of 16 different dye colors. Also the items in the creative menu should each be their own dye color.

 

It's not a model issue, because they render when placed, just not with the correct color (they only render in white, which is the first color in the blockstates colors variants). Also the blocks work fine when applied with dyes (the blocks change to their respective color), so it's probably something in a method that I'm not adding. Below are my Block and TileEntity classes, as well as the blockstate file.

This sounds like an issue with the ItemBlock and/or the model registration for the ItemBlock. Please post the code where you instantiate and register the ItemBlock and the code where you register the models for the ItemBlock(or create a repository so that we can see all of your code).

Yeah sorry I've been meaning to do that. Something got messed up with an old mod's repository and I've been trying to fix it. Anyway this is how I register the block and itemblock, but I feel like that would only be an issue with it registering the texture in the inventory. And I should add, it does register the counter model block fine (on placed, and in the inventory), just not the subitems I create with the getSubItems method in my BlockCounter.java. So I'm pretty sure they're registered correctly.

ItemBlock itself isn't suitable for blocks with variants, you need to use a subclass that overrides Item#getMetadata(int) to convert the item metadata to block metadata and calls Item#setHasSubtypes to mark the item as having variants/subtypes. ItemCloth does these and also overrides Item#getTranslationKey(ItemStack) to add the stack's colour as a suffix to the translation key (unlocalised name) so that each colour can have its own translation.

Ah, I didn't realize that. So I would need a separate class that sets hasSubtypes to true, overrides getMetadata, and a getUnlocalizedName method? Pretty much everything in the ItemCloth class?

Yes, or just use ItemCloth.

[Siqhter]

Got that working. I feel stupid, I had created a class that I planned to use for any block with subtypes, just forgot to register it in the BlockInit class as a new ItemBlock. It was the same type as ItemCloth that you just told me about. The textures in the inventory are still not registering, should I do the same with with a getSubItems subclass? I'm not sure how similar it is toSubBlocks. Thanks.

[Siqhter]

Nevermind I actually just got that working as well. I created a SubItems interface with a ResourceLocation method, and registered items that are instances of SubItems in my RegistrationHandler under Items. Thanks for your help on this.

[Siqhter]

Sorry I do have one other question. Using harvestBlock how would I get it to drop the correct color block? Right now it just drops nothing.

Well I just did this and it works fine. What is the reason for not overriding harvestBlock? 

drops.add(new ItemStack(this, 1, this.getMetaFromState(state)));

You could also have a different block for each colour, the way shulker boxes do

[Siqhter]

Well I have heard a couple people on this post say something about switching facing and color properties so that I can store color in the TE. Right now color is in the metadata, but if I instead put it in the TE, than how exactly would I call it in the block class instead of using getMetaFromState and getStateFromMeta?

[Cadiboo]

You would use the block pos you would get to get the tile entity at that pos, check if it’s yours & get the data from it.

However, with the ID limit expansion in 1.13 I would just use seperate blocks (not seperate classes) for each colour the way shulker boxes do it (with an enum). Meta is great for facing, but you shouldnt be using a TE for something like this as you can avoid all the overhead of it by just using multiple blocks

Ok, I will look into it. For now I am curious, just because I'm trying to switch color and facing so I store color in the TE. (I will end up changing it to what has been recommended). But in getActualState I'm trying to call the TE and get the data from it, but I'm not quite sure how.

@Override
public IBlockState getActualState(IBlockState state, IBlockAccess worldIn, BlockPos pos) {
    super.getActualState(state, worldIn, pos);
    TileEntityCounter tileEntity = (TileEntityCounter) worldIn.getTileEntity(pos);
    EnumDyeColor color = tileEntity.getColor();

    return state.withProperty(COLOR, color);
}

[Siqhter]

Quick update, sorry but I'm still stuck on this. My tileentity for color is:

  Reveal hidden contents

private EnumDyeColor color = EnumDyeColor.RED;

@Override
public void readFromNBT(NBTTagCompound compound) {
    super.readFromNBT(compound);
    this.color = EnumDyeColor.byMetadata(compound.getInteger("color"));
}

@Override
public NBTTagCompound writeToNBT(NBTTagCompound compound) {
    super.writeToNBT(compound);
    compound.setInteger("color", this.color.getMetadata());
    return compound;
}

and getActualState:

@Override
public IBlockState getActualState(IBlockState state, IBlockAccess worldIn, BlockPos pos) {
    super.getActualState(state, worldIn, pos);
    TileEntityCounter tileEntity = (TileEntityCounter) worldIn.getTileEntity(pos);
    EnumDyeColor color = tileEntity.getColor();

    return state.withProperty(COLOR, color);
}

but this only returns RED, obviously, but I don't understand how to get the data from the block.
