Slot Adjustments Methods

Slots were designed with the potential for the given slot amount to be changeable. This can be accomplished either by using the data format through the various operation type's, or by using the other methods provided.

Attribute Modifier

Accessories adds a system for adjusting a specific Slot types amount of slots given to the entity who equips the Accessory. Such can be done either though a programmatic or the Data Component way.

Programmatic Method

Accessories provides a programmatic way of adjusting slot amounts, which is similar in design to the data pack method. The method calls for this are found either on the AccessoriesCapability or the targeted AccessoriesContainer itself.

The following example shows how to add and remove additional ring slots, using the capability within a test Accessory:

public class RingIncreaser implements Accessory {
    private static final ResourceLocation RING_ATTRIBUTE_LOCATION = ResourceLocation.fromNamespaceAndPath("test", "additional_rings")

    //...
    @Override
    public void onEquip(ItemStack stack, SlotReference reference) {
        var map = HashMultimap.<String, AttributeModifier>create();

        map.put("ring", new AttributeModifier(RING_ATTRIBUTE_LOCATION, 100, AttributeModifier.Operation.ADDITION));

        reference.capability().addTransientSlotModifiers(map);
    }

    @Override
    public void onUnequip(ItemStack stack, SlotReference reference) {
        var map = HashMultimap.<String, AttributeModifier>create();

        map.put("ring", new AttributeModifier(RING_ATTRIBUTE_LOCATION, 100, AttributeModifier.Operation.ADDITION));

        reference.capability().removeSlotModifiers(map);
    }
    //...
}

Another Programmatic method of such is by adjusting the slots Dynamic Modifiers instead of adding to entity on equipping of the accessory:

public class HatIncreaser implements Accessory {
    private static final ResourceLocation HAT_ATTRIBUTE_LOCATION = ResourceLocation.fromNamespaceAndPath("test", "additional_hats")

    //...
    @Override
    public void getDynamicModifiers(ItemStack stack, SlotReference reference, AccessoryAttributeBuilder builder){
        // Exclusive Refers to only one instance of the modifier is allowed 
        builder.addExclusive(SlotAttribute.getSlotAttribute("hat"), HAT_ATTRIBUTE_LOCATION, 4, AttributeModifier.Operation.ADDITION);

        // Stackable Refers to any amount of the given modifier is allowed (Preappends Slot Info like the type and index to the location)
        builder.addStackable(SlotAttribute.getSlotAttribute("hat"), HAT_ATTRIBUTE_LOCATION, 4, AttributeModifier.Operation.ADDITION);
    }
    //...
}

Data Component

As outlined within the accessories:attributes Item Component you can add such to a given ItemStack to adjust the amount of equippable slots when the accessory is equipped.

Config File

The Accessories config file allows you to adjust the slot amount globally. Keep in mind that changing the defaults can heavily change the balance of your game/modpack. You can go well above a hundred ring slots for example, although that would easily clutter up your Accessory screen.

The config file is located within the ./config/ folder within your Minecraft instance under the file accessories. You can then specify new slot amounts using the "modifiers" field in the given format:

{
    //...
    "modifiers": [ // Array of json objects comprising the below structure
        {
            "slotType": "test", // Targeted Slot Name
            "amount": 23 // The Amount to shoot for as the base
        }
    ]
}
