Java‐Driven‐SlowTools

Java-Driven SlowTools

Java-driven SlowTools are dedicated registered items intended for mod developers.

The SlowTool class extends Minecraft's Item class and receives its progressive-crafting behavior from a SlowToolConfig.

Basic registration

You'll need to register SlowTools in your ModItems.class, along with a custom register method.

Register the item under your own mod's namespace, like below:

public static final SlowTool STRING_WEAVING = registerSlowTool(
    "string_weaving",
    SlowTool.config()
        .itemOutput(Items.WHITE_WOOL)
        .itemOutput(Items.STICK, 2)
        .useTime(30)
        .addToCreative()
);

private static SlowTool registerSlowTool(
        String path,
        SlowTool.SlowToolConfig config
) {
    ResourceKey<Item> key = ResourceKey.create(
        Registries.ITEM,
        Identifier.fromNamespaceAndPath(MOD_ID, path)
    );

    SlowTool item = new SlowTool(
        config,
        new Item.Properties()
            .stacksTo(1)
            .setId(key)
    );

    return Registry.register(
        BuiltInRegistries.ITEM,
        key,
        item
    );
}

Replace MOD_ID with your mod's namespace.

Important: External mods should not use SlowItems.register. That helper currently creates item keys in the slowcraft namespace. Use your own registry helper, as demonstrated above.

Configuration methods

Method	Required	Description
.itemOutput(Item)	Yes	Adds one output item
.itemOutput(Item, int)	Yes	Adds an output with an explicit count
.useTime(int)	Yes	Sets the duration in seconds
.usageSound(SoundEvent)	No	Changes the periodic crafting sound
.finishSound(SoundEvent)	No	Changes the completion sound
.excludeFromJEI()	No	Excludes the item from JEI
.addToCreative()	No	Adds the item to Slowcraft's creative tab

A SlowTool requires:

• At least one output
• No more than four outputs
• A use time greater than zero

Minimal configuration

SlowTool.config()
    .itemOutput(Items.IRON_INGOT)
    .useTime(30)

This creates a 30-second SlowTool that produces one iron ingot.

Multiple outputs

SlowTool.config()
    .itemOutput(Items.IRON_INGOT, 8)
    .itemOutput(Items.STICK, 2)
    .itemOutput(Items.DIAMOND)
    .useTime(30)

Custom sounds

SlowTool.config()
    .itemOutput(Items.WHITE_WOOL)
    .useTime(30)
    .usageSound(SoundEvents.UI_LOOM_SELECT_PATTERN)
    .finishSound(SoundEvents.FIRECHARGE_USE)

The default sounds are:

Event	Default
Usage	SoundEvents.BRUSH_GENERIC
Completion	SoundEvents.BUBBLE_POP

Creative tab behavior

Java-driven SlowTools are not added to Slowcraft's creative tab automatically.

Add one with:

.addToCreative()

Omit this when your mod already adds the item to another creative tab.

JEI behavior

Java-driven SlowTools appear in JEI by default.

To hide one:

.excludeFromJEI()

This has no effect when JEI is not installed.

Item assets

Because this is a normal registered item, your mod must also provide its normal item resources:

• Item model or client item definition
• Item texture
• Translation entry
• Any custom sound definitions

Do not manually place minecraft:damage or minecraft:max_damage components in the item's recipe. Slowcraft initializes its progress state from the registered SlowTool configuration.
