Subject: [PATCH] Configurable inter-world teleportation safety
|
|
|
|
People are able to abuse the way Bukkit handles teleportation across worlds since it provides a built in teleportation
|
|
safety check.
|
|
|
|
To abuse the safety check, players are required to get into a location deemed unsafe by Bukkit e.g. be within a chest
|
|
or door block. While they are in this block, they accept a teleport request from a player within a different world. Once
|
|
the player teleports, Minecraft will recursively search upwards for a safe location, this could eventually land within a
|
|
player's skybase.
|
|
|
|
Example setup to perform the glitch: http://puu.sh/ng3PC/cf072dcbdb.png
|
|
The wanted destination was on top of the emerald block however the player ended on top of the diamond block.
|
|
This only is the case if the player is teleporting between worlds.
