Solved Player Inventory re-rendering

In this week, I try to make a plugin to change displayName with inventory GUI.

This is a picture of my plugin:

If you see the paper on the top of inventory, This paper is showing a player the new displayName with color when the player clicked on stained glass pane to select a name color.

But my problem is: When I reRender(update) displayName of paper. All player in the server are update to same. How can I write code to update paper displayName only player who clicked not for all player in the server.

Here is my paperRender code:

Code:

   private void paperRender(String displayName){
        ItemStack paper = new ItemStack(Material.PAPER, 1);
        ItemMeta mpaper = paper.getItemMeta();
        mpaper.setDisplayName(displayName);
        paper.setItemMeta(mpaper);
       
        for(int i = 0; i < 9; i++){
            inv.setItem(i, paper);
        }
    }

onInventoryClick Event code:

Code:

@EventHandler
    public void onInventoryClick(InventoryClickEvent e){
        if(!(e.getInventory().getName().equalsIgnoreCase(inv.getName()))) return;
        if(e.getCurrentItem().getItemMeta() == null) return;
        e.setCancelled(true);
        if(e.getCurrentItem().getType() == Material.STAINED_GLASS_PANE){
            String color = colorConvertor(e.getCurrentItem().getItemMeta().getDisplayName());
            paperRender(color+"TEST");
        }
    }

Thank you.
Sorry for my English.

 

@chunza2542 You have may be only one inventory created for everyone. If i understand well what you're saying.
Create an inventory per player

Maybe just set the name in the click event, and then reopen it(reopening is basically updating it)

Code:

@EventHandler
    public void onInventoryClick(InventoryClickEvent  e) {
        ItemStack paper = new ItemStack(Material.PAPER, 1);
        ItemMeta mpaper = paper.getItemMeta();
        mpaper.setDisplayName(displayName);
        paper.setItemMeta(mpaper);
      
        e.getWhoClicked().openInventory(inventory)

 

@chunza2542
If you want each player to see something different in the inventory, you should just create different inventories.

 

Thank you. I find the solution that I should use hashmap.
