Entities must be dismounted before teleportation in order to avoid multiple issues in the server with regards to teleportation, shamefully, too many plugins rely on the events firing, which means that not firing these events caues more issues than it solves; In order to counteract this, Entity dismount/exit vehicle events have been modified to supress cancellation (and has a method to allow plugins to check if this has been set), noting that cancellation will be silently surpressed given that plugins are not expecting this event to not be cancellable. This is a far from ideal scenario, however: given the current state of this event and other alternatives causing issues elsewhere, I believe that this is going to be the best soultion all around. Improvements/suggestions welcome!

Subject: [PATCH] force entity dismount during teleportation
|
|
|
|
Entities must be dismounted before teleportation in order to avoid
|
|
multiple issues in the server with regards to teleportation, shamefully,
|
|
too many plugins rely on the events firing, which means that not firing
|
|
these events caues more issues than it solves;
|
|
|
|
In order to counteract this, Entity dismount/exit vehicle events have
|
|
been modified to supress cancellation (and has a method to allow plugins
|
|
to check if this has been set), noting that cancellation will be silently
|
|
surpressed given that plugins are not expecting this event to not be cancellable.
|
|
|
|
This is a far from ideal scenario, however: given the current state of this
|
|
event and other alternatives causing issues elsewhere, I believe that
|
|
this is going to be the best soultion all around.
|
|
|
|
Improvements/suggestions welcome!
