I'm facing an issue that in Skyblock, there are recipes that have multiple items in a single slot.

And I don't want people confusing my custom crafting table with a normal one so I wanna somehow hook into the event of preparing to craft an item (or do I have to use mixins?) and change the result slot.

I want to place some item in the result slot of a vanilla workbench when an array of itemstacks (with count of each equal to the count of other) in workbench (crafting slots) matches mine.

I don't have any screenshots of mine except hypixel's workaround (chest gui with abilities to count items in crafting slots).

The main objective is to make recipes like on screenshots possible

prn

Okay, how can I somewhat of replace vanilla crafting table? (1.16.5)

What am I doing wrong? (kotlin)

MCItems is net.minecraft.item.Items

Items is my own object containing all items that my mod has

Item.provider is "ItemStack { this }" where this is the Item

class CompressorContainer(id: Int, inv: PlayerInventory, iwpc: IWorldPosCallable) : WorkbenchContainer(id, inv, iwpc) {
    val csl: List<Slot> get() = this.inventorySlots
    override fun canInteractWith(playerIn: PlayerEntity): Boolean {
        return true
    }

    fun setResult(stack: ItemStack) {
        this.inventorySlots.first { it.slotIndex == this.outputSlot }.putStack(stack)
    }

    override fun onCraftMatrixChanged(inventoryIn: IInventory) {
        this.inventory
        val cs = this.inventorySlots.filter {
            it.slotNumber in 0..9 && it.stack !in this.inventorySlots.filter { af -> af.slotNumber in 0..9 }
                .map(Slot::getStack)
        }
        if (cs.sumOf { it.stack.count } == 160 && cs.all {
                it.stack.item in arrayOf(
                    MCItems.DIAMOND,
                    MCItems.GOLD_INGOT
                )
            }) {
            val i = when (cs.first().stack.item.registryName?.path ?: "air") {
                "gold_ingot" -> Items.ENCH_GOLD
                "diamond" -> Items.ENCH_DIAMOND
                else -> null
            }
            if (i != null) setResult(i.provider)
            log.debug("WE DID IT")
        }
        dLog()
    }

    fun dLog() {
        log.debug(csl.size)
        log.debug(csl.filter { it.slotNumber in 0..9 }
            .joinToString(", ") { "${it.slotIndex} - ${it.stack.item.registryName?.toString()} with ${it.stack.tag}" })
    }
}

Kotlin, and explanations

Just nothing, item doesn't appear in the result slot.

It's private, https://github.com/mosswork/skyblock
