Because this exploit has been widely known for years and has not been fixed by Mojang, we decided that it was worth allowing people to toggle it on/off due to how easy it is to make it configurable. It should be noted that this decision does not promise all future exploits will be configurable.

Subject: [PATCH] Add PlayerShieldDisableEvent
|
|
|
|
Called whenever a players shield is disabled. This is mainly caused by
|
|
attacking players or monsters that carry axes.
|
|
|
|
The event, while similar to the PlayerItemCooldownEvent, offers other
|
|
behaviour and can hence not be implemented as a childtype of said event.
|
|
Specifically, cancelling the event prevents the game events from being
|
|
sent to the player.
|
|
|
|
Plugins listening to just the PlayerItemCooldownEvent may not want said
|
|
sideeffects, meaning the disable event cannot share a handlerlist with
|
|
the cooldown event
