    So when I serialize my inventory to my config then restart the server my player turns into an offline player?

    Heres my error:
    Code:java
    1. Caused by: java.lang.ClassCastException: org.bukkit.craftbukkit.v1_7_R4.CraftOff
    2. linePlayer cannot be cast to org.bukkit.inventory.InventoryHolder



    Heres my codes:

    Code:java
    1. if (event.getName().equals("Accessory")) {
    2. Inventory accessory1 = Bukkit.createInventory(p, 54, "Accessory");
    3.  
    4.  
    5. if(getInventory(inventory, "Accessory") != null){
    6. p.openInventory(getInventory(inventory, "Accessory"));
    7.  
    8. } else {
    9. p.openInventory(accessory1);
    10.  
    11. }
    12.  
    13. }
    14.  


    Code:java
    1. if(e.getInventory().getTitle().equals("Accessory")) {
    2. saveInventory(e.getInventory(), inventory, "Accessory");
    3. System.out.println("Successfully Saved " + e.getInventory().getTitle() + ", holder: " + e.getInventory().getHolder() + ", UUID: " + e.getPlayer().getUniqueId());
    4. }


    Code:java
    1. public void saveInventory(Inventory inventory, FileConfiguration file, String path){
    2. int i = 0;
    3. for(ItemStack im : inventory.getContents()){
    4. file.set(path + ".contents." + i, im);
    5. i++;
    6. }
    7. file.set(path + ".maxstacksize", inventory.getMaxStackSize());
    8. file.set(path + ".inventorytitle", inventory.getTitle());
    9. file.set(path + ".inventorysize", inventory.getSize());
    10. file.set(path + ".inventoryholder", inventory.getHolder());
    11. }
    12. public Inventory getInventory(FileConfiguration file, String path){
    13. if(file.contains(path)){
    14.  
    15. Inventory inv = Bukkit.createInventory((InventoryHolder) file.get(path + ".inventoryholder"), file.getInt(path + ".inventorysize"), file.getString(path + ".inventorytitle"));
    16. inv.setMaxStackSize(file.getInt(path + ".maxstacksize"));
    17. for(int i=0; i<inv.getSize(); i++){
    18. if(file.contains(path + ".contents." + i)){
    19. inv.setItem(i, file.getItemStack(path + ".contents." + i));
    20. }
    21. }
    22. return inv;
    23. }
    24.  
    25. return null;
    26. }


    This is what my CONFIG looks like:

    Code:
    Accessory:
      contents: {}
      maxstacksize: 64
      inventorytitle: Accessory
      inventorysize: 54
      inventoryholder:
        ==: Player
        UUID: 1fa86bee-968c-3a7f-9463-ff65416f62da
    My UUID is wrong and it should be different....

    Any ideas?

    Its probally also counting the chars in between the ":"and the "1".
    Code:
    UUID: 1fa86bee-968c-3a7f-9463-ff65416f62da

    Without the full error, not much help can be given beyond "don't do that". As for the wrong UUID, you are running on an offline mode server and therefore your UUID is a hash of your username. Use an online mode server to get the correct UUID.

    My server is on online mode, I still don't know why though.

    If your server was in online mode, then you'd see a '4' instead of a '3' at the start of the third section in the UUID.

    online-mode=true

    Thats what it says on my server properties... I'v also debugged my player UUID and its different to the one in the config.

    What I'm starting to notice is that when I shut down my server and restart it, my UUID changes.

    First it looks like this:

    Code:
    Accessory:
      contents: {}
      maxstacksize: 64
      inventorytitle: Accessory
      inventorysize: 54
      inventoryholder:
        ==: Player
        Name: shohouku
    then after server restart it looks like this:

    Code:
    Accessory:
      contents: {}
      maxstacksize: 64
      inventorytitle: Accessory
      inventorysize: 54
      inventoryholder:
        ==: Player
        UUID: 1fa86bee-968c-3a7f-9463-ff65416f62da
    My UUID should look like this:
    Code:
    f7731274-3a20-406a-bf65-2a32f5569e2b
