Subject: [PATCH] Configurable Unrestricted Signs
|
|
|
|
Bukkit restricts command execution of signs to test if the sender
|
|
has permission to run the specified command. This breaks vanilla
|
|
maps that use signs to intentionally run as elevated permission.
|
|
|
|
Bukkit provides an unrestricted advancements setting, so this setting
|
|
compliments that one and allows for unrestricted signs.
|
|
|
|
We still filter sign update packets to strip out commands at edit phase,
|
|
however there is no sanity in ever expecting creative mode to not be
|
|
able to create signs with any command.
|
|
|
|
Creative servers should absolutely never enable this.
|
|
Non creative servers, enable at own risk!!!
