How to set a Maximum stack Amount?

I have a Stuck item but when i try to take item out it jumps back in because of Inventory click event, but it keeps on doubling the item, I want to know a coding maybe i could add to the playerItemDrop event???
Please help!

Code:

@EventHandler
    public void onDropItem(PlayerDropItemEvent e) {
        Player player = e.getPlayer();
        if (e.getItemDrop().getItemStack().getType() == Material.getMaterial(KeepthatItem.plugin.getConfig().getString("Item 1").toUpperCase()))
        {
            e.setCancelled(true);
            player.sendMessage(ChatColor.YELLOW + "[" + ChatColor.AQUA + "KeepthatItem" + ChatColor.YELLOW + "]" + ChatColor.RED + " " + KeepthatItem.plugin.getConfig().getString("Drop Message 1"));
        }
    }

 

Does the duplicate item stay after you relog?

 

yes. When I grab item and try to throw it it comes back then it shows 2 then throw it again gives me 4, So on. So it keeps multipling the item by 2. I want to set it so a player only get 1!

 

Hmmm, that is strange. That doesn't happen to me when I use the event...

 

Are you using Craftbukkit? If so, what version?

If you're not using CraftBukkit (e.g. Spigot), try running the plugin on Craftbukkit and see if the problem is fixed. If that fixes it, you should go ask for help on the appropriate forum for the alternate server build.

 

Im using CraftBukkit 1.7.2 But i take the item it holds it then it creates another compass!
Heres my coding.

Code:java

@EventHandler
    public void onInventoryClick(InventoryClickEvent e)
    {
        if(e.isCancelled())
        {
            e.setCancelled(true);
            return;
        }
        else
        {
            if(e.getCurrentItem() != null)
            {
                if(e.getCurrentItem().getType() == Material.getMaterial(KeepthatItem.plugin.getConfig().getString("Item 1").toUpperCase()))
                {
                    {
                        if(e.isShiftClick() || e.isLeftClick())
                        {
                            e.setCancelled(true);
                            return;
                        }
                    }
                }
            }
            if(e.getRawSlot() < 0)
                return;
            try
            {
                if(e.getInventory().getItem(e.getRawSlot()) != null)
                {
                    ItemStack item = e.getInventory().getItem(e.getRawSlot());
                    if(item.getType() == Material.getMaterial(KeepthatItem.plugin.getConfig().getString("Item 1").toUpperCase()))
                    {
                        {
                            if(e.isShiftClick() || e.isLeftClick())
                            {
                                e.setCancelled(true);
                                return;
                            }
                        }
                    }
                }
            }
            catch(ArrayIndexOutOfBoundsException ex)
            {
                //do nothing...
            }
            try
            {
                if(e.getInventory().getItem(e.getSlot()) != null)
                {
                    ItemStack item = e.getInventory().getItem(e.getSlot());
                    if(item.getType() == Material.getMaterial(KeepthatItem.plugin.getConfig().getString("Item 1")))
                    {
                        {
                            if(e.isShiftClick() || e.isLeftClick())
                            {
                                e.setCancelled(true);
                                return;
                            }
                        }
                    }
                }
            }
            catch(ArrayIndexOutOfBoundsException ex)
            {
                //do nothing...
            }

 

Wait... didn't you just talk about the PlayerDropItemEvent? And now you are using the InventoryClickEvent?

I have to say I'm a little confused...

 

When you click an item, click it down into another hotbar slot, and then right click a block with both stacks. If one disappears, that is your client finally catching up with the server in that the item doesn't actually exist. If both items stay, then you may want to submit a bug report, though you should do that with the latest dev version (1.7.9 methinks) in case it has been fixed.

 

ok. i will use recent craft bukkit

And for minoneer
I am also using this

Code:java

@EventHandler
    public void onDropItem(PlayerDropItemEvent e) {
        Player player = e.getPlayer();
        if (e.getItemDrop().getItemStack().getType() == Material.getMaterial(KeepthatItem.plugin.getConfig().getString("Item 1").toUpperCase()))
        {
            e.setCancelled(true);
            player.sendMessage(ChatColor.YELLOW + "[" + ChatColor.AQUA + "KeepthatItem" + ChatColor.YELLOW + "]" + ChatColor.RED + " " + KeepthatItem.plugin.getConfig().getString("Drop Message 1"));
        }
    }

Haha that was it thnks it was a old CraftBukkit
