The weird thing is, I copied the code(below) from another class, the pasted it in other class and changed the names of items and inventories but its not working...

InvShopEquipClick.class:

Code:

    Utils utils = Utils.getInstance();
    Invs invs = Invs.getInstance();
    Items items = Items.getInstance();

    @EventHandler
    public void onClick(InventoryClickEvent event) {
        Player player = (Player) event.getWhoClicked();

        if (event.getInventory().getName() != "§lEquipment") {
            return;
        }

        if (event.getCurrentItem().getItemMeta().getDisplayName()
                .equals(Items.shopEquipDiamondSword.getItemMeta().getDisplayName())) {
            event.setCancelled(true);
            player.closeInventory();
        }
    }
}

InvShopStartClick.class:

Code:

    Utils utils = Utils.getInstance();
    Invs invs = Invs.getInstance();
    Items items = Items.getInstance();
   
    @EventHandler
    public void onClick(InventoryClickEvent event) {
        Player player = (Player) event.getWhoClicked();

        if (event.getInventory().getName() != "§lShop") {
            return;
        }
       
        if (event.getCurrentItem().getItemMeta().getDisplayName().equals(Items.shopStartEquip.getItemMeta().getDisplayName())) {
            event.setCancelled(true);
            player.closeInventory();
            Utils.setItemInv(Items.shopEquipDiamondSword, Invs.invShopEquip, 0);
            player.openInventory(Invs.invShopEquip);
        }
       
        if (event.getCurrentItem().getItemMeta().getDisplayName().equals(Items.shopStartFood.getItemMeta().getDisplayName())) {
            event.setCancelled(true);
            player.closeInventory();
            player.openInventory(Invs.invShopFood);
        }

        if (event.getCurrentItem().getItemMeta().getDisplayName().equals(Items.shopStartMagic.getItemMeta().getDisplayName())) {
            event.setCancelled(true);
            player.closeInventory();
            player.openInventory(Invs.invShopMagic);
        }

        if (event.getCurrentItem().getItemMeta().getDisplayName().equals(Items.shopStartBlocks.getItemMeta().getDisplayName())) {
            event.setCancelled(true);
            player.closeInventory();
            player.openInventory(Invs.invShopBlocks);
        }

        if (event.getCurrentItem().getItemMeta().getDisplayName().equals(Items.shopStartRareBlocks.getItemMeta().getDisplayName())) {
            event.setCancelled(true);
            player.closeInventory();
            player.openInventory(Invs.invShopRareBlocks);
        }

        if (event.getCurrentItem().getItemMeta().getDisplayName().equals(Items.shopStartElectronics.getItemMeta().getDisplayName())) {
            event.setCancelled(true);
            player.closeInventory();
            player.openInventory(Invs.invShopElectronics);
        }
       
        if (event.getCurrentItem().getItemMeta().getDisplayName().equals(Items.closeButton.getItemMeta().getDisplayName())) {
            event.setCancelled(true);
            player.closeInventory();
        }
       
        if (event.getCurrentItem().getItemMeta().getDisplayName().equals(Items.footerBar.getItemMeta().getDisplayName())) {
            event.setCancelled(true);
        }
    }
}

When you click on the Iron Axe(Pic1) it closes the current inventory and brings you to the equipment inventory, the only item in the equipment inventory right now it a Diamond Sword(Pic2), but when you click on the Diamond Sword, nothing happens.

What am I doing wrong?

 

Code:

if (event.getInventory().getName() != "§lEquipment")

This isn't the solution to your problem, but you should compare strings using .equals and not !=

 

@Caedus
I figured out the problem, thanks for the response.
I was using != as a temporary solution because I didn't have much time when I was writing the code.
Thanks again.
