Solved Inventory GUI's!

Hi Guys!

Im trying to make this Inventory GUI Plugin, where you can click on an item and then it opens a new Menu.
I Cant figure out to open a new menu if you click on an Item ;(

I have already made another Inventory GUI! But i cant implement it in my Main GUI!

Just an Example:
Master Menu => Menu => Under Menu => Last Menu

Main GUI - Where The Other GUI needs to Open!;

Code:

@BechGameplay Your InventoryClickEvent is missing a few things.
It would be a lot easier to check the inventory's name to make sure if you have the correct inventory.

Code:

if (!ChatColor.stripColor(event.getInventory().getName())
                .equalsIgnoreCase("GUI Title Goes Here"))
            return;

Use a switch so you can set what the item will do when clicked on.

Code:

// Getting the current item type.
switch (event.getCurrentItem().getType()) {
// Setting what will happen when you click on an item.
        case ITEM:
            player.closeInventory();
                        // Open your second GUI here.
            break;
                // Setting the default for an item being clicked on.
        default:
            player.closeInventory();
            break;
}

Hope this helped a little.

 

Thanks, Helped alot!

How do i inplement the other inventory? and open it?

I tried someting like dis:

Code:

menumain.openMiningMenu(Player p);

But it didnt work
Hope your can help

 

@BechGameplay Make sure you tag me with @CodePlaysMinecraft so I know that you replied. Just do player.openInventory(invName); or, if the inventory is in another class, make the inventory static and do player.openInventory(className.invName);
Hope this helped.

 

@CodePlaysMinecraft

Thank you so Much!!! You just made my Day!

 

@BechGameplay No problem, anytime!
