CraftRecipeEvent

CraftRecipeEvent

Package: com.hypixel.hytale.server.core.event.events.ecs Extends: CancellableEcsEvent Implements: ICancellableEcsEvent Cancellable: Yes

ECS event superclass for crafting operations. Uses a Pre/Post pattern:

• CraftRecipeEvent.Pre — Fired before crafting occurs. Can be cancelled to prevent the craft.
• CraftRecipeEvent.Post — Fired after crafting succeeds. Informational — while technically cancellable (inherited from CancellableEcsEvent), the craft has already completed.

Fields / Accessors (Base Class)

Field	Type	Accessor	Mutable	Nullable
craftedRecipe	CraftingRecipe	getCraftedRecipe()	No	No
quantity	int	getQuantity()	No	No

• craftedRecipe — The recipe being crafted.
• quantity — The number of times the recipe is being crafted in this operation.

CraftRecipeEvent.Pre

Extends: CraftRecipeEvent Cancellable: Yes (inherited)

Fired before the crafting operation takes effect. Cancelling this event prevents the craft from occurring — ingredients are not consumed and no output is produced.

Fired By

• CraftingManager (line 155) via componentAccessor.invoke(ref, event) — ECS dispatch before a crafting operation executes.

Listening

public class MyCraftPreHandler extends EntityEventSystem<EntityStore, CraftRecipeEvent.Pre> {
    @Override
    public Query<EntityStore> getQuery() {
        return MY_COMPONENT_TYPE;
    }

    @Override
    public void handle(int index, ArchetypeChunk<EntityStore> chunk,
                       Store<EntityStore> store, CommandBuffer<EntityStore> commandBuffer,
                       CraftRecipeEvent.Pre event) {
        CraftingRecipe recipe = event.getCraftedRecipe();
        int quantity = event.getQuantity();

        // Example: prevent crafting of restricted recipes
        if (isRestrictedRecipe(recipe)) {
            event.setCancelled(true);
        }
    }
}

// Register in plugin setup():
getEntityStoreRegistry().registerSystem(new MyCraftPreHandler());

CraftRecipeEvent.Post

Extends: CraftRecipeEvent Cancellable: Yes (inherited, but craft has already completed)

Fired after the crafting operation has completed successfully. The ingredients have already been consumed and the output produced. While this event inherits cancellability from CancellableEcsEvent, cancelling it at this stage does not undo the craft. This event is primarily useful for logging, analytics, or triggering side effects.

Fired By

• CraftingManager (line 184) via componentAccessor.invoke(ref, event) — ECS dispatch after a crafting operation completes.

Listening

public class MyCraftPostHandler extends EntityEventSystem<EntityStore, CraftRecipeEvent.Post> {
    @Override
    public Query<EntityStore> getQuery() {
        return MY_COMPONENT_TYPE;
    }

    @Override
    public void handle(int index, ArchetypeChunk<EntityStore> chunk,
                       Store<EntityStore> store, CommandBuffer<EntityStore> commandBuffer,
                       CraftRecipeEvent.Post event) {
        CraftingRecipe recipe = event.getCraftedRecipe();
        int quantity = event.getQuantity();

        // Example: track crafting statistics
        craftingStats.recordCraft(recipe, quantity);
    }
}

// Register in plugin setup():
getEntityStoreRegistry().registerSystem(new MyCraftPostHandler());
