This is work in progress.
|
||||||
|
|
||||||
|
Aim: Create objects that can be locked and shared.
|
||||||
|
|
||||||
|
Comes with a chest and sign. Ought to work with xdoors2locked.
|
||||||
|
|
||||||
|
Who can open/use a locked object?
|
||||||
|
- the owner (always)
|
||||||
|
- anyone with the diglocks priv
|
||||||
|
- anyone with the openlocks priv (only use - not dig)
|
||||||
|
- anyone whose name has been added by the owner with the /add playername command
|
||||||
|
- anyone who knows and types in the password that the owner did set with /set thisisthepassword
|
||||||
|
|
||||||
|
TODO:
|
||||||
|
- check if players added via /add playername actually exist
|
||||||
|
- add groups of players for easier handling (i.e. a group :trusted for trusted users)
|
||||||
|
- add key and keychain as objects required to use locked objects
|
||||||
|
- add crafting receipes
|
||||||
|
- better handling of the name of the object
