Pull a UUID From Config?

  1. Hello! I was just wondering how i can pull a UUID (Thats a string) from the config? I got this code from the Bukkit Wiki idk if it works yet but i think it will fit my needs :D

    Code (Text):
    List<String> listOfStrings = Arrays.asList("Hello World", "Welcome to Bukkit", "Have a Good Day!");
    this.getConfig().set("path.to.list", listOfStrings);
    Thanks in advance! This has been driving me crazy!!!
  2. Once you have a String, you can call UUID.fromString, this will either return the UUID or it will throw an exception if the string doesnt represent a UUID
  3. Ty but if i do UUID.fromString(p.getUniqueId()) it doesnt work how can i fix this :D Again ty so much
  4. Deconstruct what you're doing. Player#getUniqueId returns a UUID, UUID.fromString takes in a String. A UUID isn't a String.
    This call to fromString is redundant, as getUniqueId already returns a UUID
  5. Save a UUID: FileConfiguration#set(String, UUID#toString)
    Load a UUID: UUID.fromString(FileConfiguration#getString(String))

  6. Would this work??
    if(UUID.fromString(p.getUniqueId().toString()) != null){
    p.setDisplayName("§b§lBEAST " + nick);
  7. ... Why would you need to take a player's uuid and turn it into a string then turn it back into a uuid to check if it's null? It's not even possible for that to be null.

  10. What exactly are you trying to accomplish?
  11. And if i use UUID.fromString(FileConfiguration#getString(String)) my string would be player.getUUID or whatever
  12. Try to get a UUID from a config
  13. Before you get a UUID from config, you need to save it in the config. And then, you need to do UUID.fromString(config.getString("uuid")) to get the UUID back. But if you just need to check if it's null, don't bother turning it into a UUID. Just do
    if (!config.contains("uuid")) {

  14. But my string is my UUID, I have the UUID then a Nickname as the Value

    You aren't clear at all on what you're attempting to do, and how you have it set up.

  16. ok so, What i am doing is saving a UUID to the config

    5749w8650ejldh gfd hg (What ever):
    and then giving it a value

    5749w8650ejldh gfd hg: <Nickname>
    Then when they join i get there UUID and the string and apply the Name
  17. But idk how to get it :D
  18. Save the players UUID to your file:
    Code (Text):
    Check if the player exists in the file:
    Code (Text):
    if(yourConfig.getString(player.getUniqueId().toString()) != null) {
    UUID id = UUID.fromString(yourConfig.getString(player.getUniqueId().toString());
    Not too hard, and I suggest learning a bit more about java and files.
  19. Thanks for not being mean at all about it!

  20. This is completely redundant and incorrect... If the value in the config is stored by UUID then you would not be returning the UUID from the config.
