# 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?
**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);
```
