When a Player drops an ItemStack while in creative mode by placing it outside
of their inventory window, the slot number in the packet is -1. The check
that was added to avoid throwing InventoryCreativeEvent excessively didn't
take this into account, and would cause an ArrayIndexOutOfBoundsException to
be thrown when attempting to get the slot specified by the packet.
This change shorts the invocation of player.defaultContainer.getSlot(
packet107setcreativeslot.b) to only occur if the slot id is within the range
of the Inventory. This prevents attempting to get the slot from a location
that is actually outside of the Inventory.
This commit brings the InventoryClickEvent up to date with the new Minecraft
changes in 1.5.
InventoryDragEvent (thanks to @YLivay for his PR) is added to represent the
new "dragging" or "painting" functionality, where if you hold an itemstack and
click-drag over several slots, the items will be split evenly (left click) or
1 each (right click).
The ClickType enum is used to represent what the client did to trigger the
event.
The InventoryAction enum is reserved for future expansion, but will be used to
indicate the approximate result of the action.
Additionally, handling of creative inventory editing is improved with the new
InventoryCreativeEvent, and handling of numberkey presses is also improved
within InventoryClickEvent and CraftItemEvent.
Also, cancelling a creative click now displays properly on the client.
Adresses BUKKIT-3692, BUKKIT-4035, BUKKIT-3859 (new 1.5 events),
BUKKIT-2659, BUKKIT-3043, BUKKIT-2659, and BUKKIT-2897 (creative click events).
Currently there are several cases where a player will have their inventory
screen closed client side but we will not call an event. To correct this
we call the event when the server is the cause of the inventory closing
instead of just when the client is the cause. We also ensure the server is
closing the inventory reliably so we get the events. Additionally this
commit also calls the event when a player disconnects which will handle
kicks, quits, and server shutdown.
We used to fall Item.filterData() for this but that method is meant for
converting item data to block data during placement and does the wrong
thing for this case. Instead we just see if the item should have data and
if not set it to zero. We also have to filter wool data explicitly because
clients crash when given invalid wool data.
The player would have no permissions (other than their OP status)
when checked in the Quit event. This is because we removed permissions
before the event occurred. By calling it afterwards, we can persist
the data until the server finally removes the player.
