    • setTexturePack

      @Deprecated void setTexturePack(@NotNull String url)
      Deprecated.
      Minecraft no longer uses textures packs. Instead you should use setResourcePack(String).
      Request that the player's client download and switch texture packs.

      The player's client will download the new texture pack asynchronously in the background, and will automatically switch to it once the download is complete. If the client has downloaded and cached the same texture pack in the past, it will perform a file size check against the response content to determine if the texture pack has changed and needs to be downloaded again. When this request is sent for the very first time from a given server, the client will first display a confirmation GUI to the player before proceeding with the download.

      Notes:

      • Players can disable server textures on their client, in which case this method will have no affect on them. Use the PlayerResourcePackStatusEvent to figure out whether or not the player loaded the pack!
      • There is no concept of resetting texture packs back to default within Minecraft, so players will have to relog to do so or you have to send an empty pack.
      • The request is send with "null" as the hash. This might result in newer versions not loading the pack correctly.
      Parameters:
      url - The URL from which the client will download the texture pack. The string must contain only US-ASCII characters and should be encoded as per RFC 1738.
      Throws:
      IllegalArgumentException - Thrown if the URL is null.
      IllegalArgumentException - Thrown if the URL is too long.
    • setResourcePack

      void setResourcePack(@NotNull String url)
      Request that the player's client download and switch resource packs.

      The player's client will download the new resource pack asynchronously in the background, and will automatically switch to it once the download is complete. If the client has downloaded and cached the same resource pack in the past, it will perform a file size check against the response content to determine if the resource pack has changed and needs to be downloaded again. When this request is sent for the very first time from a given server, the client will first display a confirmation GUI to the player before proceeding with the download.

      • The request is send with "null" as the hash. This might result in newer versions not loading the pack correctly.
      Parameters:
      url - The URL from which the client will download the resource pack. The string must contain only US-ASCII characters and should be encoded as per RFC 1738.
      Throws:
      IllegalArgumentException - Thrown if the URL is null.
      IllegalArgumentException - Thrown if the URL is too long. The length restriction is an implementation specific arbitrary value.
    • setResourcePack

      void setResourcePack(@NotNull String url, @NotNull byte[] hash)
      Request that the player's client download and switch resource packs.

      The player's client will download the new resource pack asynchronously in the background, and will automatically switch to it once the download is complete. If the client has downloaded and cached a resource pack with the same hash in the past it will not download but directly apply the cached pack. When this request is sent for the very first time from a given server, the client will first display a confirmation GUI to the player before proceeding with the download.

      Notes:

      • Players can disable server resources on their client, in which case this method will have no affect on them. Use the PlayerResourcePackStatusEvent to figure out whether or not the player loaded the pack!
      • There is no concept of resetting resource packs back to default within Minecraft, so players will have to relog to do so or you have to send an empty pack.
      Parameters:
      url - The URL from which the client will download the resource pack. The string must contain only US-ASCII characters and should be encoded as per RFC 1738.
      hash - The sha1 hash sum of the resource pack file which is used to apply a cached version of the pack directly without downloading if it is available. Hast to be 20 bytes long!
      Throws:
      IllegalArgumentException - Thrown if the URL is null.
      IllegalArgumentException - Thrown if the URL is too long. The length restriction is an implementation specific arbitrary value.
      IllegalArgumentException - Thrown if the hash is null.
      IllegalArgumentException - Thrown if the hash is not 20 bytes long.
