Subject: [PATCH] BlockDestroyEvent
|
|
|
|
Adds an event for when the server is going to destroy a current block,
|
|
potentially causing it to drop. This event can be cancelled to avoid
|
|
the block destruction, such as preventing signs from popping when
|
|
floating in the air.
|
|
|
|
This can replace many uses of BlockPhysicsEvent
