[1.10.2] Item overrides not working

[Guest]

I have an item block which (for legacy reasons) stores its subtype in the stack's tag compound. For the item I have registered a custom IItemPropertyGetter:

private static class TypePropertyGetter implements IItemPropertyGetter
    {
        @Override
        public float apply(ItemStack stack, @Nullable World world, @Nullable EntityLivingBase entity)
        {
            if (stack.hasTagCompound())
            {
                return stack.getTagCompound().getInteger("type")-1;
            }
            return 0;
        }
    }

 

What proves that the stack actually has a tag compound and the correct data is that the item's tooltip shows the correct data. The items (except for the first type) however all get the item model of the second type.

This is the part of my model which controls the overrides:

"overrides": [
        {
            "predicate": {
                "type": 1
            },
            "model": "rfutilities:block/blockCapacitorHardened"
        },
        {
            "predicate": {
                "type": 2
            },
            "model": "rfutilities:block/blockCapacitorReinforced"
        },
        {
            "predicate": {
                "type": 3
            },
            "model": "rfutilities:block/blockCapacitorResonant"
        },
        {
            "predicate": {
                "type": 4
            },
            "model": "rfutilities:block/blockCapacitorBasic"
        },
        {
            "predicate": {
                "type": 5
            },
            "model": "rfutilities:block/blockCapacitorDouble"
        },
        {
            "predicate": {
                "type": 6
            },
            "model": "rfutilities:block/blockCapacitorOctadic"
        }
    ]

 

I also know for sure that the models are correct as the blocks use the same model and they each get the correct one.

With a breakpoint on the return value in the if statement of the apply method of the IItemPropertyGetter I found that there is a pattern of 12 calls to this method with the value in the stackTagCompound being 1 for the first five calls and then the correct value for the next seven calls. The call stack is always the same. As I am checking for the stack having an NBTTagCompound, I know that those calls are only made for the items in the slots of the creative tab and not for the icon of the creative tab as that stack doesn't have NBT data.

"model": "rfutilities:block/blockCapacitorReinforced"

 

Are these models actually different? Did you copy-paste and forget to customize the copies?

[Guest]

The model that contains the overrides section is the parent of the other six models. The models used for the items are the same as the ones for the blocks (same json file) and the block models work as expected.

[jeffryfisher]

OK... you override getSubItems, but did you set hasSubtypes to true?

[yooksi]

OK... you override getSubItems, but did you set hasSubtypes to true?

From what he has shown us I would say no.

 

@XFactHD In order to get your subtypes to work and call

getSubItems

you have to call

setHasSubtypes(true)

from inside your

ItemBlockRFCapacitor

ItemBlock class constructor.

[Guest]

You are right, I most likely forgot that, I'll check if that fixes it.

[Guest]

I did really forget that, but it unfortunately doesn't fix my problem.

[yooksi]

I did really forget that, but it unfortunately doesn't fix my problem.

 

Did you set item max damage to 0, and are you changing item damage at any point in your code?

[Guest]

I did not set the max item damage to 0 and I also do not change the metadata at any point in my code, the only difference between these seven item blocks is the type value stored in the NBT tab of the itemstack.

[yooksi]

I did not set the max item damage to 0 and I also do not change the metadata at any point in my code, the only difference between these seven item blocks is the type value stored in the NBT tab of the itemstack.

 

The easiest solution would be to stop using NBT to store metadata, and use the local metadata value in Item for that, like it was meant to be used.

[Guest]

I can't really do that right now as it would break the mod for everyone currently using it but I couldtry to implement some kind of legacy code.
