Subject: [PATCH] Properly remove entities on dimension teleport
|
|
|
|
To teleport an entity between dimensions, the server makes a copy
|
|
and puts the copy in the new location, and marks the old one dead.
|
|
|
|
If this method got called for the same world in the same tick,
|
|
the entity would not have been removed from the UUID map, and the
|
|
world readd would fail.
|
|
|
|
This can be triggered even with a plugin if the entity is teleported
|
|
twice in the same tick, from world A to B, then back from B to A.
|
|
|
|
The re-add to A will fail to add the entity to the world. It will
|
|
actually be there, but it will not be visible on the client until
|
|
the server is restarted to re-try the add to world process again.
|
|
|
|
This bug was unlikely to be seen by many due to the double teleport
|
|
requirement, but plugins (such as my own) use this method to
|
|
trigger a "reload" of the entity on the client.
