Forge version: 1.12.2

 

My demand is: all of my mod item ,using same obj model, using different obj according different itemMeta. And, all of my mod item using same blockState.json.

that my clientProxy#preInit code :

	for (Item item : ModItems.itemList) {
			for (int i = 0; i < 10; i++) {
				ModelLoader.setCustomModelResourceLocation(item, i,
						new ModelResourceLocation("mfbl:staff_" + i, "inventory"));
				System.out.println("mfbl:staff_" + i + "," + item.getUnlocalizedName() + "," + item.getRegistryName());
			}
		}

 

Qustion is:

When i call ModelLoader#setCustomModelResourceLocation for each item reigster  the same modelResourceLocation, then source code put it into  customModels map ,the  map will equal the  Pair#hashcode that from item.delegate and metadata. follow this :

 

 public static void setCustomModelResourceLocation(Item item, int metadata, ModelResourceLocation model)
    {
        customModels.put(Pair.of(item.delegate, metadata), model);
        ModelBakery.registerItemVariants(item, model);
    }

 

I found the code in item.delegate  , the 'name' is ModelResourceLocation#path:

    @Override
    public int hashCode()
    {
        return Objects.hashCode(name);
    }

 

 

so,just first item register obj normally.I'm create 10 item that render by obj.  now i have 1 blockStates json,   I want the 10 item share the same blockStates json, how to do ?

 

edit: I found some thread about StateMapperBase, but it's only aim at block.it's no use for me.

Could you be more specific about what your trying to do? You can easily just register a custom model resource location pointing to a blockstate and variant.

 

ModelLoader.setCustomModelResourceLocation(item, meta, new ModelResourceLocation( new ResourceLocation(MODID, blockstateLocation), blockstateVariant));

Sorry,I forget attach forge version ,it's 1.12.2.

I have 10 item,every item was render by the same obj model.

so, when i foreach every item call ModelLoader#setCustomModelResourceLocation(item, meta, new ModelResourceLocation( "mfbl:share_obj_blockstates.json"),

the "ModelLoader#setCustomModelResourceLocation" method will put ModelResourceLocation("mfbl:share_obj_blockstates.json") to a map, the map will equal "mfbl:share_obj_blockstates.json" if exist. 

The mechanism not allow different item use share same blockstates.json. the mechanism lead just first register item was render normally,other item was render by missing model instead of.

What should i do?My English is not good,if i describe not clearly, please point out.

Your resource location shouldn’t contain “.json” and you should make a resourcelocation and then call toString() on it to both protect yourself from future changes to the resource location format and to make sure that you don’t get a problem like using uppercase names

I'm very thank you for you ,i can extends ResourceLocation and overrider hashCode method, is you ,give me inspiration,thanks again.

Wait what why? How does that have anything to do with what I said?
