Hello, I have an item that I want to have different types of that holds every ingot registered in the game. As in, I want it to have subtypes of every registered ingot that has currently been loaded. However, I do not know how to access this information. I'd also like for this to have configurability, as in, I'd like the user to add (or remove) their own subtype rather easily by modifying a list in config. I know how to add these subtypes, however, I do not know how to automatically them from registered items within forge.

 

Thanks.

Yeah, I see in the documentation that common prefixes, like ingot, can be found. However, I'm not seeing anything to get the items from these prefixes. Would I use something like OreDictionary#doesOreNameExist and check for each item I want to be a subtype? 

 

Also, I have a quick question with subtypes, is it possible to assign different names for each type, depending on a value that is stored upon the item (ex. type)?

OreDictionary.getOres(name) will return all stacks with a given registered oredict name.

OreDictionary.getOreNames() will return all registered oredict names.

OreDictionary.getOreName(OreDictionary.getOreIDs(stack)[j]) will get the ore name(s) for a given item stack (note the array access).

    public NonNullList<ItemStack> getAcceptableCatalystTypes() {
        NonNullList<ItemStack> returnList = new NonNullList<>();
        for(String oreName : OreDictionary.getOreNames()) {
            if(oreName.contains("ingot")){
                for(ItemStack ingot : OreDictionary.getOres(oreName)){
                    returnList.add(ingot);
                }
            }
        }

        for(String stringLoc : VoidConfig.general.resourceCatalystTypes){
            ResourceLocation location = new ResourceLocation(stringLoc);
            if(ForgeRegistries.ITEMS.containsKey(location)){
                returnList.add(new ItemStack(ForgeRegistries.ITEMS.getValue(location)));
            }else if(ForgeRegistries.BLOCKS.containsKey(location)){
                returnList.add(new ItemStack(ForgeRegistries.BLOCKS.getValue(location)));
            }
        }
    }

Here is what I have so far. I don't really know if the config bit is entirely correct, as this was my first time accessing the ForgeRegistries values. I will be testing and seeing what happens. Thanks for the info.

You might want to consider using streams for readability

Yeah, I will look into doing that.

 

Now I need to create these subtypes, however, I've stumped myself with how to do this. As this items' subtypes depends on other items being loaded, I'm stuck. I want to make it so that the item stores what type (either via nbt or capabilities), and have different crafting recipes. Could anyone give me pointers on how to do this?

 

Thanks.

Closest I can think of is the ToolMold that I made.

Eg. this recipe (and its siblings).

 

The tool mold's subitems are determined based on the available recipes which I manually manage via an API hook, as item models need to be baked before recipes are ever loaded. But the code you created above could be placed into a function that creates the resulting item list, which then is referenced by both your item's getSubItems method and your ModelRegistryEvent method.
