# Modding Helper API

A comprehensive **utility library** for Fabric mod development providing 28 helpers, 6 fluent builders, and 200+ methods to reduce boilerplate and accelerate development.

---

## 🎯 What is Modding Helper API?

**Perfect for:**

- 🔧 Reducing boilerplate code

- ✅ Following best practices automatically

- 🚀 Building mods faster

- 🧪 Testing with confidence

## 🚀 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);

```
