Solved How dose one create a gui within a gui?

So i want to create another gui when i click a icon as shown here


but i am having some trouble figuring how to do that
Today is my first time creating a solo bukkit plugin but i do know java for 3 years now, I am just used to making mods

Could one of you kindly help me add another gui?
Here is the code so far for when you click on the icon it switches to the new GUI

Code:java

 
@EventHandler
    public void onInventoryClick(InventoryClickEvent e){
        if (!e.getInventory().getName().equalsIgnoreCase(inv.getName())) return;
        if (e.getCurrentItem().getItemMeta()== null) return;
 
if (e.getCurrentItem().getItemMeta().getDisplayName().contains("Firework List"))
        {
            e.setCancelled(true);
 
            e.getWhoClicked().closeInventory();
        }
 
    }
 

Thank you kindly for the help if you decide to

 

Close current gui and open new one.

 

How would the code look like with mine?

 

McKiller5252 Inception. You would just open the inventory to the player???

 

So something like

e.getWhoClicked().openInventory()

 

McKiller5252 Perhaps so.

 

Let me try it and see if it work.

Oh damn it did work



but i need to add a small time delay on when pressing the icon to open this gui

McKiller5252 You can use scheduleSyncDelayedTask or runTaskLater

 

Thank you so much for the help
