# Player skin

There are three ways of defining a player skin:

* Setting your player UUID (see [here](/feature/player-uuid.md)) to their Mojang UUID, clients by default retrieve the skin based on this value. This is done automatically by `MojangAuth.init()`
* Changing it in the `PlayerSkinInitEvent` event
* Using the method `Player#setSkin(PlayerSkin)`

## How to retrieve skin data from Mojang

### Using PlayerSkin methods

`PlayerSkin` offers some utils methods to retrieve a skin using simple information such as a Mojang UUID or a Minecraft username

```java
PlayerSkin skinFromUUID = PlayerSkin.fromUuid(MOJANG_UUID_AS_STRING);

PlayerSkin skinFromUsername = PlayerSkin.fromUsername("Notch");
```

{% hint style="warning" %}
Those methods make direct requests to the Mojang API, it is recommended to cache the values.
{% endhint %}

### Retrieve texture value & signature manually

Most of what I will say is described here: <https://wiki.vg/Mojang_API#Username_-.3E_UUID_at_time>

You firstly need to get your Mojang UUID, which can be done by a request based on your username:

```
 GET https://api.mojang.com/users/profiles/minecraft/<username>
```

Then, after getting your UUID:

```
 GET https://sessionserver.mojang.com/session/minecraft/profile/<uuid>?unsigned=false
```

You'll get here both the texture value and the signature. Those values are used to create a `PlayerSkin`.

### PlayerSkinInitEvent

The event is called at the player connection and is used to define the skin to send to the player the first time. It is as simple as

```java
GlobalEventHandler globalEventHandler = MinecraftServer.getGlobalEventHandler();
globalEventHandler.addListener(PlayerSkinInitEvent.class, event -> {
   PlayerSkin skin = new PlayerSkin(textureValue, signature);
   event.setSkin(skin);
});
```

### Player#setSkin

```java
PlayerSkin skin = new PlayerSkin(textureValue, signature);
player.setSkin(skin);
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://wiki.microtus.dev/feature/player-skin.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
