Add a recipe

Recipes are registered from the common entrypoint. The RecipeBuilder covers the three most common recipe types.

Shaped crafting​

scripts/common/<bundle>/Common.groovy
import de.luckymcdev.foundryengine.common.builder.recipe.RecipeBuilder
import net.minecraft.world.item.Items

def shaped = RecipeBuilder.shaped(id("wand_from_diamond"), Items.DIAMOND_HORSE_ARMOR)
        .pattern(" D ", " S ", " S ")
        .define('D' as char, Items.DIAMOND)
        .define('S' as char, Items.STICK)
        .unlockedBy("has_diamond", InventoryChangeTrigger.TriggerInstance.hasItems(Items.DIAMOND))

The first argument is the recipe id, the second is the output item. .pattern lays out the grid, .define maps a character to an ingredient.

Shapeless crafting​

def shapeless = RecipeBuilder.shapeless(id("gems_from_diamond"), Items.DIAMOND)
        .requires(Items.DIAMOND)
        .requires(Items.EMERALD)
        .count(3)
        .unlockedBy("has_diamond", InventoryChangeTrigger.TriggerInstance.hasItems(Items.DIAMOND))

.requires adds one ingredient per call. .count sets the number of output items.

Smelting​

def smelting = RecipeBuilder.smelting(id("smelt_smooth"), Blocks.SMOOTH_STONE)
        .ingredient(Blocks.STONE)
        .experience(0.5f)
        .cookingTime(200)
        .unlockedBy("has_stone", InventoryChangeTrigger.TriggerInstance.hasItems(Blocks.STONE))

Register them​

BundleEvents.registry {
    it.recipes(shaped, shapeless, smelting)
}

Every recipe needs an .unlockedBy so it appears in the recipe book. The first argument is a name you choose; the second is the condition, usually an InventoryChangeTrigger that fires when the player has the ingredient.
