    Are you sure changeDisplay() is actually executed? Try adding a print statement with a specific message after that line, and see if you get that message in the console.

    By the way, are you running in offline mode?

    It doesn't support offline servers, unfortunately. That can be rectified, but it would be against the forum policy to post that here.

    Then it's probably not executed properly. Add a bunch of calls to System.out.println(String) and see if things gets executed.

    Also, it doesn't look like the class Kom is actually registered as an executor, at least from the code you've posted. You must do that in order for it to be executed.

    it is possible to make skin by url?
  6. It's actually possible to do it by url, if you add a url --> image converter in the method.
    Nope, as it gets the skin by the UUID.
    And also for some reason it doesn't work for me. I tried version 1.3 and 1.2, and it still doesn't work. I might try 1.1. Tried it, doesn't work neither.

    I know other people will see the new skin if i'll change it, but will it change for me?

    In order to do that, you'd have your actual player avatar invisible, and then spawn a new player entity with the correct skin and name, while synchronizing its position and actions.

    Unfortunately, this is not ideal for players with a relatively high ping, as the displayed action or movement is now subject to the intrinsic latency between the server and the client.

    Interesting. Could you add ProtocolLib to your server and type the following command:
    /packet add play server named_entity_spawn
    Then you should be able to see what is transmitted to the clients.

    By the way, are they using Minecraft 1.7.9?

    I fixed it, wrong imports. And sorry ,my fault. I wish you continued success. :)

    Hey, I'm using version 1.3 of your resource (yes, I'm using CB 1.7.9 and it's online mode server), but when I use a command to change a player's skin and name, every online player gets DC and when they try to re-login they got this message: "Internal Exception: net.minecraft.util.io.netty.handler.codec.EncoderException: java.lang.RuntimeException: An internal error occured." And there's no error on the console.

    That's really strange, cause it was working before and I don't really remember changing any thing related to this on my plugin.

    Can you help me?

    Still works?

    Also, is this backwards?

    else {
      profile.getProperties().put(name, new Property(value, name));

    nice name you have there ^^
    But to your question, seems like ProtocolLib can't find an tracker for you. Looks like an protocollib problem. (Is it working correctly?)

    I seem to be getting an issue here:
    1. WrappedGameProfile result = new WrappedGameProfile(
    2. extractUUID(original.getName()),
    3. displayName != null ? displayName : original.getName()
    4. );

    Apparently, UUID cannot be applied to String. I don't know, am I being a complete noob here? My IntellIj is refusing to build with this error, so, I need a fix, please!

    As you might have noticed, these classes have a few bugs.

    As you might know Mojang has put a maximum of 1 UUID request per minute on their UUID database. Because your server itself sends a request on-login, you won't be able to change the skin within the first minute after login. After you have done 1 request, I highly advise you to cache the result, because you won't be able to resend a request within a minute.

    I am working on a new, better working version, which should be able handle these problems. I hope I have given you enough information about the problems with these classes now,
