[SOLVED] How to cancel an item drop/toss by player, without losing the item?

[Evert]

For a server-side mod, that can make some areas private, so other players can't break or build there.

I want to make that those players also can't drop(Q) items there.

 

I can use 'ItemTossEvent', but if that is canceled, the item disappears completely.

 

I tried 'ItemEvent', but that is called with item events where no players are involved and I can't find a way to determine what player dropped the item, so there is no way of knowing if the event has to be canceled.

 

What I'm looking for is:

- A method to return the lost item when using 'ItemTossEvent'.

or

- A method to determine the player name that dropped an item when using 'ItemEvent'.

or

- Some other way to make this work.

 

Thank you.

Has ItemTossEvent the player who dropped it? If it has you can just put the item back to player's inventory and delete the item.

Thank you. That works.

 

It is a bit buggy.

When an item is dropped with Q it gets replaced immediately, but when it is dropped with the right click from the inventory screen, it seems to disappear. It reappears later with an inventory change or after reconnecting.

 

	public void itemEvent(ItemTossEvent event)
{
	if ( event.isCancelable() )
	{
		ItemStack itemStack = event.entityItem.item;
		event.setCanceled(true);
		event.player.inventory.addItemStackToInventory(itemStack);
	}
}

}

 

Maybe use:

event.player.inventory.onInventoryChanged();

 

after:

event.player.inventory.addItemStackToInventory(itemStack);

I tried it, but it doesn't make a difference.

Sorry for necrobumping, but does anybody have a solution?

Like i wrote before. It works, but when items are dropped from the inventory screen, they seem to disappear for a while, but they're not really lost. They reappear after some other action with the inventory or a reconnect.

Using the drop key (default: Q) works fine.

 

	public void itemEvent(ItemTossEvent event)
{
	if ( event.isCancelable() )
	{
		ItemStack itemStack = event.entityItem.item;
		event.setCanceled(true);
		event.player.inventory.addItemStackToInventory(itemStack);
	}
}

 

Since mc 1.4.6, I had to change one line:

ItemStack itemStack = event.entityItem.func_92014_d();
