[SOLVED][1.12.2] Issues with multistate blocks models

[moonlyer]

Hi modders,

I have a custom Block with two states (for example meta 0, and meta 1). I've created and registered ItemBlock for this Block, just to have both variants in creative for testing. I've also made override of Block.getItemDropped so that my block could drop another item when destroyed. Everything is working fine except for models. I have 2 issues:

1. When my block with meta 1 is destroyed - my item gets dropped with placeholder model (item model that drops from block with meta 0 is fine).

I've managed to fix this by adding another line like this:

			ModelLoader.setCustomModelResourceLocation(item, 0, new ModelResourceLocation(item.getRegistryName(),"inventory"));
			ModelLoader.setCustomModelResourceLocation(item, 1, new ModelResourceLocation(item.getRegistryName(),"inventory"));//new line

But it feels not right to manually add models to every meta state. Ideally I want to call setCustomModelResourceLocation only once for my Item. How should I fix this? Should I drop my Item in onBlockDestroyedByPlayer instead? 

 

2. Two ItemStacks, that got generated from my ItemBlock, have auto-generated icons in the inventory. I want to change them to custom icons. I guess I should do something with .json files, but I was not able to find the solution. What should my actions be in general if I want to add custom icons to ItemBlock?

Blocks that have variants defined by the blockstate json file need to specify their variant string as their model, not "inventory"

Yeah, I get that part. That line above refers to the item that only dropped by my block. That item is not my item block. My item block is registered right as you suggest.

No, you registered it like this:

Well there is some misunderstanding.

 

WILD_DUST - my ItemBlock

UNREFINED_DUST - my Item that's just referenced in my override of Block.getItemDropped

That's how I register my items:

public class ElcraftItems 
{
	//Item Variables to be registered
	public static final Item DUST_COIN= new DustCoin();
	public static final Item UNREFINED_DUST=new UnrefinedDust();
	public static final Item WILD_DUST= new WildDustItemBlock(ElcraftBlocks.WILD_DUST).setRegistryName(ElcraftBlocks.WILD_DUST.getRegistryName());	
			
	
	public static void Register(IForgeRegistry<Item> reg)
	{ 
		ArrayList<Item> itemsToBeInitialized=new ArrayList<Item>();
		
		itemsToBeInitialized.add(DUST_COIN);
		itemsToBeInitialized.add(WILD_DUST);
		itemsToBeInitialized.add(UNREFINED_DUST);
		
		//Register Items
		
		

		for (Item i:itemsToBeInitialized)
		{
			
			reg.register(i);
			Elcraft.proxy.registerItemModels(i);
			
		}
	}
}

@Override
	public void registerItemModels(Item item)
	{
		StateMapperBase b = new DefaultStateMapper();
		Block block;
		
		
		try
		{
			block=((ItemBlock)item).getBlock();
		}
		catch (ClassCastException x)
		{
			block=null;
		}
		BlockStateContainer bsc;
		
		//If ItemBlock
		if (block!=null)
		{
			//if (item.getHasSubtypes())
			//{}
				
				bsc = block.getBlockState();
				ImmutableList<IBlockState> values = bsc.getValidStates();
				for(IBlockState state : values) 
				{
					String str = b.getPropertyString(state.getProperties());
					ModelResourceLocation res = new ModelResourceLocation(item.getRegistryName(), str);
					//System.out.println(res.getResourcePath());
					ModelLoader.setCustomModelResourceLocation(item,block.getMetaFromState(state),res);
						
				}
		}
		else
		{
			ModelLoader.setCustomModelResourceLocation(item, 0, new ModelResourceLocation(item.getRegistryName(),"inventory"));
			ModelLoader.setCustomModelResourceLocation(item, 1, new ModelResourceLocation(item.getRegistryName(),"inventory"));
		}
	}

 

So, do you suggest that i still need to register item model that is completely unrelated to my block with block's variant string?

So WILD_DUST drops UNREFINED_DUST, and when it does so, it's icon is the purple and black cube?

 

Yeah, you dropped it with a metadata of 1 and you registered an icon for metadata of 0.

Right. But the problem is that UNREFINED_DUST is not an ItemBlock and does not have reference to a multistate block. So there's no way I could  know every meta that I need to register in registerItemModels other than manually code it. Is there a way to drop UNREFINED_DUST with meta 0 regardless of WILD_DUST meta?

[Draco18s]

No.

You need to change your block class to deal with dropped items correctly. Namely, not return 1 from damageDropped() when dropping the unrefined dust. If you can't handle that, override getDrops() instead

Thanks. I think I got it. It's really easy to get lost if you don't understand completely how minecraft classes interact with each other. 

P.S. My second issue (inablility to have different models for Block and it's ItemBlock) was solved by registering ItemBlock with a different registry name, and creating anoter blockstate .json. Previously I used the same registry name for block and ItemBlock.
