How to structure Turtle Upgrades now?

[SirEdvin]

So, before 1.21 a had a lot of this code to register turtle upgrades¹:

 val MIMIC = ModPlatform.registerTurtleUpgrade(
        MimicPeripheral.upgradeID,
        TurtleUpgradeSerialiser.simpleWithCustomItem { upgradeID, stack ->
            PeripheralTurtleUpgrade.dynamic(stack.item, ::MimicPeripheral) { upgradeID }
        },
    )

I liked this approach a lot, because it helped me to not create a lot of excessive classes. But now, Upgrade class should have a link that would point to the upgrade type. But there is not way to get upgrade type instance when you creating a Turtle/Pocket upgrade.

Should I try to create custom UpgradeType for this or I can solve this issue in another way?

Yep! You can probably create a variant of simpleWithCustomItem that constructs your upgrade with the type:

fun <T : UpgradeBase> createWithCustomItem(factory: (ty: UpgradeType<T>, stack: ItemStack) -> T): UpgradeType<T> {
    lateinit var type: UpgradeType<T>
    type = UpgradeType.create(
        BuiltInRegistries.ITEM.byNameCodec()
            .xmap({ factory(type, ItemStack(it)) }, { it.craftingItem.item })
            .fieldOf("item"),
    )
    return type
}

Thanks! I will do like this and hope it will work. I am still don't quite get codecs, data components and all of this, and I am very grateful that you spent some time to help me to understand it a little better!
