## 🎯 What is Modding Helper API?

**Modding Helper API** is a production-ready Fabric library that provides essential utilities for mod developers. Instead of writing the same helper code repeatedly, use battle-tested implementations that handle edge cases, null safety, and best practices automatically.

**Perfect for:**

– 🔧 Reducing boilerplate code
– ✅ Following best practices automatically
– 🚀 Building mods faster
– 🧪 Testing with confidence
– 📚 Learning from clean code examples

## 🚀 Quick Start

### 1. Add Dependency

In your `fabric.mod.json`:

“`json
{
  “depends”: {
    “fabricloader”: “>=0.18.4”,
    “minecraft”: “~1.21.11”,
    “fabric-api”: “*”,
    “moddinghelperapi”: “*”
  }
}
“`

### 2. Import and Use

“`java
import dk.mosberg.util.*;

public class MyMod implements ModInitializer {
    @Override
    public void onInitialize() {
        // Create an item
        ItemStack diamond = ItemStackHelper.of(“minecraft:diamond”, 64);

        // Create styled text
        MutableText msg = new TextBuilder(“Success!”)
            .success()  // Green color
            .bold()
            .build();

        // Search for blocks
        List<BlockPos> ores = BlockSearchHelper.findInRadius(
            world, pos, 50, Blocks.DIAMOND_ORE
        );
    }
}
“`

### 3. Start Building

That’s it! You now have access to all 28 helpers and 6 builders.

## 📋 Helper Categories

### Item Management

“`java
// Create items safely
ItemStack stack = ItemStackHelper.of(“minecraft:diamond”, 64);
ItemStack stack2 = ItemStackHelper.of(Items.GOLD_INGOT, 1);

// Check item state
if (ItemStackHelper.isEmpty(stack)) { /* … */ }
if (ItemStackHelper.isFull(stack)) { /* … */ }

// Inventory operations
InventoryHelper.addItem(inventory, stack);
int count = InventoryHelper.countItem(inventory, Items.DIAMOND);
InventoryHelper.removeItem(inventory, Items.DIAMOND, 10);
“`

### Block & World Operations

“`java
// Find blocks
List<BlockPos> ores = BlockSearchHelper.findInRadius(world, pos, 50, Blocks.DIAMOND_ORE);
BlockPos nearest = BlockSearchHelper.findNearest(world, pos, 100, Blocks.IRON_ORE);

// Manipulate block states
BlockState state = world.getBlockState(pos);
if (BlockStateHelper.hasProperty(state, Properties.LIT)) {
    BlockState newState = BlockStateHelper.setBoolean(state, Properties.LIT, true);
}

// Check redstone signals
if (RedstoneHelper.isPowered(world, pos)) {
    activateFeature();
}
“`

### Entity & Player Management

“`java
// Work with entities
if (EntityHelper.isLiving(entity)) {
    double distance = EntityHelper.distance(player, entity);
    EntityHelper.damage(entity, 5.0f);
}

// Player utilities
ServerPlayerEntity player = PlayerHelper.get(server, “Steve”);
if (player != null && PlayerHelper.isAlive(player)) {
    PlayerHelper.message(player, “Hello!”);
    float health = PlayerHelper.getHealth(player);
}
“`

### Text & Display

“`java
// Create styled text
MutableText text = new TextBuilder(“Hello”)
    .bold()
    .color(Formatting.GOLD)
    .append(” World”)
    .build();

// Preset colors
MutableText success = new TextBuilder(“✓ Success”).success().build();  // Green
MutableText error = new TextBuilder(“✗ Error”).error().build();        // Red
MutableText warn = new TextBuilder(“⚠ Warning”).warning().build();     // Yellow
“`

### Vector Mathematics

“`java
// Vector operations
Vec3d v1 = new Vec3d(0, 0, 0);
Vec3d v2 = new Vec3d(10, 5, 3);

double distance = VectorHelper.distance(v1, v2);
Vec3d direction = VectorHelper.direction(v1, v2);  // Normalized
Vec3d midpoint = VectorHelper.midpoint(v1, v2);

// Builder pattern
Vec3d transformed = new Vec3dBuilder(v1)
    .add(5, 0, 0)
    .scale(2.0)
    .normalize()
    .build();
“`

### Networking

“`java
// Server-side packet handling
NetworkHelper.registerConnectionHandler(
    Identifier.of(“mymod”, “join”),
    player -> sendInitialData(player)
);

// Broadcast packets
NetworkHelper.broadcastPacket(playerList, payload);

// Send to single player
NetworkHelper.sendToPlayer(player, payload);
“`

### Logging & Debugging

“`java
// Structured logging
var logger = LogHelper.getLogger(“mymod”, “ItemHandler”);
logger.info(“Processing item: {}”, itemName);
logger.warn(“Unexpected value: {}”, value);
logger.error(“Operation failed”, exception);

// Event system
EventHelper events = new EventHelper();
events.subscribe(“player_join”, event -> {
    handlePlayerJoin(event);
});
events.dispatch(“player_join”, joinEvent);
“`
