设置皮肤 Minecraft 实体播放器 - Java

在 Minecraft 中，实体播放器（EntityPlayer）是代表玩家的实体。可以通过设置实体播放器的皮肤来定制化玩家的外观。本文将介绍如何在 Java 中设置实体播放器的皮肤。

步骤

1. 获取 Minecraft 玩家皮肤

要设置实体播放器的皮肤，我们需要获取 Minecraft 玩家的皮肤。可以通过 Mojang 的正版 API 来获取。

String playerName = "Notch"; // 玩家名
URL url = new URL("https://api.mojang.com/users/profiles/minecraft/" + playerName);
URLConnection connection = url.openConnection();
InputStream stream = connection.getInputStream();
Scanner scanner = new Scanner(stream);

StringBuilder jsonBuilder = new StringBuilder();
while (scanner.hasNext()) {
    jsonBuilder.append(scanner.next());
}

JsonElement json = JsonParser.parseString(jsonBuilder.toString());
String uuid = json.getAsJsonObject().get("id").getAsString();

stream.close();
scanner.close();

注意：需要使用 com.google.gson.Gson 库来解析 JSON。

2. 下载 Minecraft 玩家皮肤

获取到玩家的 UUID 后，就可以使用 Mojang 的正版 API 下载玩家的皮肤了。

URL url = new URL("https://crafatar.com/skins/" + uuid + ".png");
InputStream stream = url.openStream();
Image skinImage = ImageIO.read(stream);

stream.close();

注意：需要使用 javax.imageio.ImageIO 库来解析图片。

3. 将 Minecraft 玩家皮肤设置给实体播放器

获取到皮肤后，就可以将其设置给实体播放器了。

EntityPlayer player = ...; // 实体播放器
ResourceLocation skinLocation = new ResourceLocation("minecraft", "textures/entity/player/" + player.getUniqueID() + ".png");
Minecraft.getMinecraft().getTextureManager().loadTexture(skinLocation, new DynamicTexture(skinImage));

注意：需要使用 net.minecraft.util.ResourceLocation、net.minecraft.client.renderer.texture.DynamicTexture 和 net.minecraft.client.Minecraft 类。

    URL url = new URL("https://api.mojang.com/users/profiles/minecraft/" + playerName);
    URLConnection connection = url.openConnection();
    InputStream stream = connection.getInputStream();
    Scanner scanner = new Scanner(stream);

    StringBuilder jsonBuilder = new StringBuilder();
    while (scanner.hasNext()) {
      jsonBuilder.append(scanner.next());
    }

    JsonElement json = JsonParser.parseString(jsonBuilder.toString());
    String uuid = json.getAsJsonObject().get("id").getAsString();

    stream.close();
    scanner.close();

    url = new URL("https://crafatar.com/skins/" + uuid + ".png");
    stream = url.openStream();
    Image skinImage = ImageIO.read(stream);

    stream.close();

    ResourceLocation skinLocation = new ResourceLocation("minecraft", "textures/entity/player/" + player.getUniqueID() + ".png");
    Minecraft.getMinecraft().getTextureManager().loadTexture(skinLocation, new DynamicTexture(skinImage));
  }
}
