AnvilLib


AnvilLib is a NeoForge mod library developed by Anvil Dev, providing Minecraft mod developers with a series of practical tools and frameworks.

Features

AnvilLib adopts a modular design and includes the following functional modules:

Module Introduction

Config Module

Provides an annotation-based configuration management system to simplify the definition and management of mod configurations.

Key Features:

• Define configuration classes using @Config annotation
• Add configuration comments with @Comment
• Define numerical ranges with @BoundedDiscrete
• Create nested configurations with @CollapsibleObject
• Automatically generate client configuration GUI

Usage Example:

@Config(name = "my_mod", type = ModConfig.Type.COMMON)
public class MyModConfig {
    @Comment("Enable debug mode")
    public boolean debugMode = false;

    @Comment("Maximum count")
    @BoundedDiscrete(min = 1, max = 100)
    public int maxCount = 10;
}

// Register configuration
MyModConfig config = ConfigManager.register("my_mod", MyModConfig::new);

Integration Module

Provides a framework for mod integrations, supporting automatic loading of integration code based on the presence of other mods.

Key Features:

• Declare integration classes with @Integration annotation
• Support for version range matching
• Support for different runtime environments (CLIENT / DEDICATED_SERVER / DATA)

Usage Example:

@Integration(value = "jei", version = "[19.0,)")
public class JEIIntegration {
    public void init() {
        // JEI integration logic
    }
}

Network Module

Provides a NeoForge networking abstraction with package-based packet auto-registration.

Key Features:

• Define packet direction using IClientboundPacket / IServerboundPacket / IInsensitiveBiPacket
• Automatically register packet classes in a package via NetworkRegistrar.register(...)
• Supports PLAY, CONFIGURATION, and COMMON protocols

Usage Example:

@SubscribeEvent
public static void onRegisterPayload(RegisterPayloadHandlersEvent event) {
    PayloadRegistrar registrar = event.registrar("1");
    NetworkRegistrar.register(registrar, "my_mod");
}

Recipe Module

Provides an in-world recipe system, allowing recipes to be executed in the world (rather than in crafting tables).

Key Features:

• Supports custom recipe triggers (Trigger)
• Supports recipe predicates (Predicate) for conditional checks
• Supports multiple recipe outcomes (Outcome)
• Built-in priority system
• Full datapack support

Recipe Components:

• Trigger: Conditions to trigger the recipe (e.g., item dropping, explosions)
• Predicate: Recipe matching conditions
• Outcome: Recipe execution results (e.g., spawning items, setting blocks)

Moveable Entity Block Module

Allows blocks with block entities to be pushed by pistons while preserving their data.

Usage Example:

public class MyBlock extends Block implements IMoveableEntityBlock {
    @Override
    public CompoundTag clearData(Level level, BlockPos pos) {
        // Return block entity data to preserve
        BlockEntity be = level.getBlockEntity(pos);
        return be != null ? be.saveWithoutMetadata(level.registryAccess()) : new CompoundTag();
    }

    @Override
    public void setData(Level level, BlockPos pos, CompoundTag nbt) {
        // Restore block entity data at new position
        BlockEntity be = level.getBlockEntity(pos);
        if (be != null) {
            be.loadAdditional(nbt, level.registryAccess());
        }
    }
}

Registrum Module

A registration system based on Registrate, simplifying the registration process for items, blocks, entities, etc.

Key Features:

• Chain-style API design
• Automatic language file generation
• Automatic datapack generation
• Support for various builders

Usage Example:

public static final Registrum REGISTRUM = Registrum.create("my_mod");

public static final RegistryEntry<Item> MY_ITEM = REGISTRUM
    .item("my_item", Item::new)
    .properties(p -> p.stacksTo(16))
    .register();

Main Module

anvillib-neoforge-1.21.1 is the aggregate artifact. It bundles and re-exports:

• config
• integration
• network
• recipe
• moveable-entity-block
• registrum

Dependency Integration

Gradle (Groovy DSL)

repositories {
    mavenCentral() // This project is already uploaded to Maven Central
}

dependencies {
    // Full library
    implementation "dev.anvilcraft.lib:anvillib-neoforge-1.21.1:2.0.0"

    // Or import individual modules as needed
    implementation "dev.anvilcraft.lib:anvillib-config-neoforge-1.21.1:2.0.0"
    implementation "dev.anvilcraft.lib:anvillib-integration-neoforge-1.21.1:2.0.0"
    implementation "dev.anvilcraft.lib:anvillib-network-neoforge-1.21.1:2.0.0"
    implementation "dev.anvilcraft.lib:anvillib-recipe-neoforge-1.21.1:2.0.0"
    implementation "dev.anvilcraft.lib:anvillib-moveable-entity-block-neoforge-1.21.1:2.0.0"
    implementation "dev.anvilcraft.lib:anvillib-registrum-neoforge-1.21.1:2.0.0"
}

Gradle (Kotlin DSL)

repositories {
    mavenCentral() // This project is already uploaded to Maven Central
}

dependencies {
    implementation("dev.anvilcraft.lib:anvillib-neoforge-1.21.1:2.0.0")

    // Optional single-module example
    implementation("dev.anvilcraft.lib:anvillib-network-neoforge-1.21.1:2.0.0")
}
