Fixed bug in create_object that sometimes caused rooms to be created with a location !=None
Expanded @destroy to better handle names and not just dbrefs.
/Griatch
Added AttrKeys and FlagKeys - locks depending on the value of the unlocker's attribute or if they have a flag set.
Finally I updated @lock to handle all these lock types. There are a large amount of possible configurations though, so more testing is needed.
/Griatch
The main command to use is @lock, which accept three types of locks at the moment, and three types of keys:
Locks: DefaultLock, UseLock, EnterLock
Keys: ObjectIDs, Groups, Permissions
This offers the most useful functionality - stopping people from picking up things, blocking exits and stopping
anyone from using an object.
If the attributes lock_msg, use_lock_msg and enter_lock_msg are defined on the locked object, these will be used
as error messages instead of a standard one (so "the door is locked" instead of "you cannot traverse that exit").
Behind the scenes, there is a new module, src/locks.py that defines Keys and Locks. A Locks object is a collection
of Lock types. This is stored in the LOCKS attribute on objects. Each Lock contains a set of Keys that might be
of mixed type and which the player must match in order to pass the lock.
/Griatch
Other small bugfixes, fixes to @dig to properly call creation hooks of all newly created objects (it was not setting anything before). Also fixed some of the annoying bugs around using several of the building commands that didn't properly handle spaces around the separator = symbol.
/Griatch
GLOBAL_STATE_TABLE.add_state() before adding commands to it. The state can now be much more configured by including as much or as
little of the normal default commands into it as wanted (so you can now have states which are almost as normal, except some
commands are missing or change their behaviour ... illness or darkness comes to mind). The possibilities here are limitless.
* States now also optionally allow traversing exits as well as using command tables defined on objects.
* States now better handle error messages (so if you try 'look' in a state which does not contain a look command you will no
longer get the 'Huh?' but will be told that the command is not available at the moment).
* All examples in commands/examples/ have been updated to use the new State system. Also added a @test_state function for trying out
the functionality.
* Added hooks at_before_move() and at_after_move(), useful for character based move-restrictions and checks (e.g. movement speed)
* Minor tweaks to the event system; avoiding the counters to go negative should they hit an uncaught traceback.
* Small fixes of typos and minor extra safety checks.
