## ⚓**For developers**
### ⏩**What is Rtag?**
Rtag provides an easy way to edit NBT tags without NMS and avoiding bad performance impact on big servers.
So it's **completely shadeable**, you can implement rtag directly in your plugin.
For detailed information about Rtag, visit [the wiki page](https://docs.saicone.com/rtag).
Rtag convert any Java object into NBT tag and viceversa:
```java
// Using Item
RtagItem tag = new RtagItem(item);
// Using Entity
RtagEntity tag = new RtagEntity(entity);
// Using block
RtagBlock tag = new RtagBlock(block);
// --- Put values
// Set the value "Custom Text" at "display.Name" path
tag.set("Custom Text", "display", "Name");
// Or set an integer at "someKey" path
tag.set(40, "someKey");
// Including compatibility with any type of object like MyObject
MyObject myobject = new MyObject();
tag.set(myobject, "any", "path");
// So you can add lists
tag.set(new ArrayList(), "list", "path");
// And add values into list
tag.add((short) 3, "list", "path");
// Or replace the values of existing list
tag.set((short) 5, "list", "path", 0); // index 0
// --- Get values
// Value from path "display" -> "Name"
String name = tag.get("display", "Name");
// Safe value get from path "someKey", or -1 by default
int intValue = tag.getOptional("someKey").or(-1);
int sameValue = tag.getOptional("someKey").asInt(-1); // This method try to convert any type to int
// Explicit value get for custom objects
MyObject sameobject = tag.getOptional("any", "path").as(MyObject.class);
// Merge values into tag
tag.merge(Map.of("asd", 123, "someKey", 41), true);
// Get lists
List list = tag.get("list", "path");
// Get list value from index
short listValue = tag.get("list", "path", 0); // index 0
// Get the entire object tag as Map of Java objects
Map map = tag.get();
// --- Load changes into object
// Load changes into original object
tag.load();
// RtagItem as the option to create an item copy with changes loaded
ItemStack itemCopy = tag.loadCopy();
// --- Update current tag if the original object was edited
tag.update();
```

## ⭐**Features**
There are other libraries to edit NBT tags, why should Rtag be used over the others?
### 1️⃣**Easy to understand**
You don't need to be an expert with NBT tags, just with simple methods you can set and get normal Java objects.
```java
Rtag rtag = new Rtag();
rtag.set(compound, "Normal string", "CustomTagPath");
String string = rtag.get(compound, "CustomTagPath");
```
The main RtagEditor instances have methods to make tag editing easier.
```java
RtagItem tag = new RtagItem(item);
tag.setUnbreakable(true);
tag.setRepairCost(20);
int level = tag.getEnchantmentLevel("unbreaking"); // Enchantment enum, name or id
RtagEntity tag = new RtagEntity(entity);
tag.setAttributeBase("generic.attackDamage", 0.5);
RtagBlock tag = new RtagBlock(block);
tag.setCustomName("§eColored name");
```
You can edit objects using functions inside RtagEditor instances and return any type of object.
```java
ItemStack item = ...;
// Edit original
RtagItem.edit(item, tag -> {
tag.set("Custom Text", "display", "name");
tag.set(30, "someKey");
});
// Return a copy
ItemStack copy = RtagItem.edit(item, tag -> {
tag.set(30, "someKey");
return tag.loadCopy();
});
```
### 2️⃣**Edit data components! (Experimental)**
Since Minecraft 1.20.5, items use components to save vanilla data.
With RtagItem you can edit components in a simple way as normal Java objects.
```java
RtagItem tag = new RtagItem(item);
if (tag.hasComponent("minecraft:custom_model_data")) {
tag.removeComponent("minecraft:custom_model_data");
} else {
tag.setComponent("minecraft:custom_model_data", 40);
}
Object component = tag.getComponent("minecraft:custom_model_data");
Integer number = ComponentType.encodeJava("minecraft:custom_model_data", component).orElse(null);
```
### 3️⃣**Store custom objects**
By default, Rtag uses the Gson library inside Bukkit to (de)serialize custom objects, but you need to get them using explicit conversion.
```java
Rtag rtag = new Rtag();
MyObject myObject = new MyObject();
rtag.set(compound, myObject, "CustomTagPath");
MyObject sameObject = rtag.getOptional(compound, "CustomTagPath").as(MyObject.class);
```
So you can register (de)serializers in Rtag instance to set and get custom objects with automatic conversion.
This conversion put an additional key into your saved tag to detect it using the provided ID.
, RtagDeserializer {
public MyObjectSerializer(Rtag rtag) {
rtag.putSerializer(MyObject.class, this);
rtag.putDeserializer(this);
}
// MyObject -> Map
@Override
public String getInID() {
// It's suggested to use a unique namespaced key
return "myplugin:MyObject";
}
// Map -> MyObject
@Override
public String getOutID() {
return "myplugin:MyObject";
}
@Override
public Map serialize(MyObject object) {
// Convert your custom object into map
}
@Override
public MyObject deserialize(Map compound) {
// Convert compound into you custom object
}
}
```
Then you can get your custom object without explicit conversion.
```java
Rtag rtag = new Rtag();
new MyObjectSerializer(rtag);
MyObject myObject = new MyObject();
rtag.set(compound, myObject, "CustomTagPath");
MyObject sameObject = rtag.get(compound, "CustomTagPath");
```
### 4️⃣**TagStream instances**
With ItemTagStream instance you can convert items into Base64|File|Bytes|Map|String and viceversa.
Including **cross-version support**! Save an item on any version and get on any version without compatibility problems. Materials, enchantments, potions... etc, all will be converted!
```java
ItemTagStream tag = ItemTagStream.INSTANCE;
String string = tag.toBase64(item);
ItemStack sameItem = tag.fromBase64(string)[0];
```
### 5️⃣**Textured heads**
With SkullTexture class you can get textured heads from base64, url, texture ID, player name or uuid.
```java
// Base64
ItemStack head = SkullTexture.getTexturedHead("eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvZmVkZmEyZTBmZGVhMGMwNDIzODA0Y2RiNWI2MmFkMDVhNmU5MTRjMDQ2YzRhM2I3ZTM1NWJmODEyNjkxMjVmZCJ9fQ==");
// URL
ItemStack head = SkullTexture.getTexturedHead("http://textures.minecraft.net/texture/fedfa2e0fdea0c0423804cdb5b62ad05a6e914c046c4a3b7e355bf81269125fd");
// Texture ID
ItemStack head = SkullTexture.getTexturedHead("fedfa2e0fdea0c0423804cdb5b62ad05a6e914c046c4a3b7e355bf81269125fd");
// Player name
ItemStack head = SkullTexture.getTexturedHead("Rubenicos");
// Player UUID
ItemStack head = SkullTexture.getTexturedHead("7ca003dc-175f-4f1f-b490-5651045311ad");
```
### 6️⃣**Chat Component**
With ChatComponent class you can convert (json) strings into chat components and viceversa.
```java
// To component
Object component = ChatComponent.fromJson("{\"bold\":true,\"italic\":false,\"color\":\"dark_purple\",\"text\":\"Colored text!\"}");
Object sameComponent = ChatComponent.fromString("§5§lColored text!");
// From component
String json = ChatComponent.toJson(component);
String string = ChatComponent.toString(component);
// Cross-compatibility
String json = ChatComponent.toJson("§5§lColored text!");
String string = ChatComponent.toString("{\"bold\":true,\"italic\":false,\"color\":\"dark_purple\",\"text\":\"Colored text!\"}");
```
### ✨**Pretty NBT**
For more information, visit [the wiki page](https://docs.saicone.com/rtag/feature/chat-component/#pretty-nbt-formatter).
Format any nbt object into single or multiple lines using default, hex or minimessage color palette.
Or use your custom color palette.
