[1.18.2] Datagen'ing custom recipe types?

[Mattah12]

I have a custom crafting table block, Foundry, with slots arranged in a ring formation. There is a also a slot I use for a tool that gets hurt upon use.

Spoiler

public FoundryMenu(int pContainerId, Inventory inv, BlockEntity entity, ContainerData data) {
        super(Registration.FOUNDRY_MENU.get(), pContainerId);
        checkContainerSize(inv, 8);
        blockEntity= ((FoundryBE) entity);
        this.level = inv.player.level;
        this.data = data;

        addPlayerInventory(inv);
        addPlayerHotbar(inv);

        this.blockEntity.getCapability(CapabilityItemHandler.ITEM_HANDLER_CAPABILITY).ifPresent(handler -> {
            this.addSlot(new SlotItemHandler(handler, 0, 9, 34));
            this.addSlot(new SlotItemHandler(handler, 1, 80, 8));
            this.addSlot(new SlotItemHandler(handler, 2, 107, 22));
            this.addSlot(new SlotItemHandler(handler, 3, 107, 48));
            this.addSlot(new SlotItemHandler(handler, 4, 80, 60));
            this.addSlot(new SlotItemHandler(handler, 5, 51, 48));
            this.addSlot(new SlotItemHandler(handler, 6, 51, 22));
            this.addSlot(new KanResultSlot(handler, 7, 153, 32));
        });

        addDataSlots(data);
    }

 

I have set up a custom recipe class also - https://github.com/Mattah12/Kanohi_Craft2022/blob/master/src/main/java/com/Mattah12/kanohicraft/recipes/FoundryRecipe.java

What I want to know is how I'd go about making a datagen class for this custom recipe type? My plans will require a lot of possible recipes so I don't want to have to manually create all the jsons. I already have datagen set up for vanilla crafting, but can't get my head around how I go about creating the pattern. - https://github.com/Mattah12/Kanohi_Craft2022/blob/master/src/main/java/com/Mattah12/kanohicraft/datagen/KanRecipes.java

Can that be done in the existing KanRecipes class? Would it require a new one?

You need your own RecipeBuilder like vanilla has for its recipes.

Why did you use ifPresent? Did you assume that your capability is not always present?
