Roleplaying base system for Evennia
Contribution - Griatch, 2015
This module contains the ContribRPObject, ContribRPRoom and
ContribRPCharacter typeclasses. If you inherit your
objects/rooms/character from these (or make them the defaults) from
these you will get the following features:
- Objects/Rooms will get the ability to have poses and will report
the poses of items inside them (the latter most useful for Rooms).
- Characters will get poses and also sdescs (short descriptions)
that will be used instead of their keys. They will gain commands
for managing recognition (custom sdesc-replacement), masking
themselves as well as an advanced free-form emote command.
In more detail, This RP base system introduces the following features
to a game, common to many RP-centric games:
- emote system using director stance emoting (names/sdescs).
This uses a customizable replacement noun (/me, @ etc) to
represent you in the emote. You can use /sdesc, /nick, /key or
/alias to reference objects in the room. You can use any
number of sdesc sub-parts to differentiate a local sdesc, or
use /1-sdesc etc to differentiate them. The emote also
identifies nested says and separates case.
- sdesc obscuration of real character names for use in emotes
and in any referencing such as object.search(). This relies
on an SdescHandler `sdesc` being set on the Character and
makes use of a custom Character.get_display_name hook. If
sdesc is not set, the character's `key` is used instead. This
is particularly used in the emoting system.
- recog system to assign your own nicknames to characters, can then
be used for referencing. The user may recog a user and assign
any personal nick to them. This will be shown in descriptions
and used to reference them. This is making use of the nick
functionality of Evennia.
- masks to hide your identity (using a simple lock).
- pose system to set room-persistent poses, visible in room
descriptions and when looking at the person/object. This is a
simple Attribute that modifies how the characters is viewed when
in a room as sdesc + pose.
- in-emote says, including seamless integration with language
obscuration routine (such as contrib/rpg/rplanguage.py)
Installation:
Add `RPSystemCmdSet` from this module to your CharacterCmdSet:
```python
# mygame/commands/default_cmdsets.py
# ...
from evennia.contrib.rpg.rpsystem.rpsystem import RPSystemCmdSet <---
class CharacterCmdSet(default_cmds.CharacterCmdset):
# ...
def at_cmdset_creation(self):
# ...
self.add(RPSystemCmdSet()) # <---
```
You also need to make your Characters/Objects/Rooms inherit from
the typeclasses in this module:
```python
# in mygame/typeclasses/characters.py
from evennia.contrib.rpg.rpsystem.rpsystem import ContribRPCharacter
class Character(ContribRPCharacter):
# ...
```
```python
# in mygame/typeclasses/objects.py
from evennia.contrib.rpg.rpsystem.rpsystem import ContribRPObject
class Object(ContribRPObject):
# ...
```
```python
# in mygame/typeclasses/rooms.py
from evennia.contrib.rpg.rpsystem.rpsystem import ContribRPRoom
class Room(ContribRPRoom):
# ...
```
Examples:
> look
Tavern
The tavern is full of nice people
*A tall man* is standing by the bar.
Above is an example of a player with an sdesc "a tall man". It is also
an example of a static *pose*: The "standing by the bar" has been set
by the player of the tall man, so that people looking at him can tell
at a glance what is going on.
> emote /me looks at /Tall and says "Hello!"
I see:
Griatch looks at Tall man and says "Hello".
Tall man (assuming his name is Tom) sees:
The godlike figure looks at Tom and says "Hello".
Note that by default, the case of the tag matters, so `/tall` will
lead to 'tall man' while `/Tall` will become 'Tall man' and /TALL
becomes /TALL MAN. If you don't want this behavior, you can pass
case_sensitive=False to the `send_emote` function.
Extra Installation Instructions:
1. In typeclasses/character.py:
Import the `ContribRPCharacter` class:
`from evennia.contrib.rpg.rpsystem.rpsystem import ContribRPCharacter`
Inherit ContribRPCharacter:
Change "class Character(DefaultCharacter):" to
`class Character(ContribRPCharacter):`
If you have any overriden calls in `at_object_creation(self)`:
Add `super().at_object_creation()` as the top line.
2. In `typeclasses/rooms.py`:
Import the `ContribRPRoom` class:
`from evennia.contrib.rpg.rpsystem.rpsystem import ContribRPRoom`
Inherit `ContribRPRoom`:
Change `class Room(DefaultRoom):` to
`class Room(ContribRPRoom):`
3. In `typeclasses/objects.py`
Import the `ContribRPObject` class:
`from evennia.contrib.rpg.rpsystem.rpsystem import ContribRPObject`
Inherit `ContribRPObject`:
Change `class Object(DefaultObject):` to
`class Object(ContribRPObject):`
4. Reload the server (`reload` or from console: "evennia reload")
5. Force typeclass updates as required. Example for your character:
`type/reset/force me = typeclasses.characters.Character`

Read a raw emote and parse it into an intermediary
format for distributing to all observers.
Args:
sender (Object): The object sending the emote. This object's
recog data will be considered in the parsing.
candidates (iterable): A list of objects valid for referencing
in the emote.
string (str): The string (like an emote) we want to analyze for keywords.
search_mode (bool, optional): If `True`, the "emote" is a query string
we want to analyze. If so, the return value is changed.
case_sensitive (bool, optional): If set, the case of /refs matter, so that
/tall will come out as 'tall man' while /Tall will become 'Tall man'.
This allows for more grammatically correct emotes at the cost of being
a little more to learn for players. If disabled, the original sdesc case
is always kept and are inserted as-is.
fallback (string, optional): If set, any references that don't match a target
will be replaced with the fallback string. If `None` (default), the
parsing will fail and give a warning about the missing reference.
Returns:
(emote, mapping) (tuple): If `search_mode` is `False`

all references replaced with internal-representation {#dbref}

Returns an Object matching a search string/condition, taking
sdescs into account.
Perform a standard object search in the database, handling
multiple results and lack thereof gracefully. By default, only
objects in the current `location` of `self` or its inventory are searched for.
Args:
searchdata (str or obj): Primary search criterion. Will be matched
against `object.key` (with `object.aliases` second) unless
the keyword attribute_name specifies otherwise.
**Special strings:**
- `#<num>`: search by unique dbref. This is always
a global search.
- `me,self`: self-reference to this object
- `<num>-<string>` - can be used to differentiate
between multiple same-named matches
global_search (bool): Search all objects globally. This is overruled
by `location` keyword.
use_nicks (bool): Use nickname-replace (nicktype "object") on `searchdata`.
typeclass (str or Typeclass, or list of either): Limit search only
to `Objects` with this typeclass. May be a list of typeclasses
for a broader search.
location (Object or list): Specify a location or multiple locations
to search. Note that this is used to query the *contents* of a
location and will not match for the location itself -
if you want that, don't set this or use `candidates` to specify
exactly which objects should be searched.
attribute_name (str): Define which property to search. If set, no
key+alias search will be performed. This can be used
to search database fields (db_ will be automatically
appended), and if that fails, it will try to return
objects having Attributes with this name and value
equal to searchdata. A special use is to search for
"key" here if you want to do a key-search without
including aliases.
quiet (bool): don't display default error messages - this tells the
search method that the user wants to handle all errors
themselves. It also changes the return value type, see
below.
exact (bool): if unset (default) - prefers to match to beginning of
string rather than not matching at all. If set, requires
exact matching of entire string.
candidates (list of objects): this is an optional custom list of objects
to search (filter) between. It is ignored if `global_search`
is given. If not set, this list will automatically be defined
to include the location, the contents of location and the
caller's contents (inventory).
nofound_string (str): optional custom string for not-found error message.
multimatch_string (str): optional custom string for multimatch error header.
use_dbref (bool or None): If None, only turn off use_dbref if we are of a lower
permission than Builder. Otherwise, honor the True/False value.
Returns:
match (Object, None or list): will return an Object/None if `quiet=False`,
otherwise it will return a list of 0, 1 or more matches.
Notes:
To find Accounts, use eg. `evennia.account_search`. If
`quiet=False`, error messages will be handled by
`settings.SEARCH_AT_RESULT` and echoed automatically (on
error, return will be `None`). If `quiet=True`, the error
messaging is assumed to be handled by the caller.

Allows to customize how your sdesc is displayed (primarily by
changing colors).
Args:
sdesc (str): The sdesc to display.
obj (Object): The object to which the adjoining sdesc
belongs. If this object is equal to yourself, then
you are viewing yourself (and sdesc is your key).
This is not used by default.
Kwargs:
ref (str): The reference marker found in string to replace.
This is on the form #{num}{case}, like '#12^', where
the number is a processing location in the string and the
case symbol indicates the case of the original tag input
- `t` - input was Titled, like /Tall
- `^` - input was all uppercase, like /TALL
- `v` - input was all lowercase, like /tall
- `~` - input case should be kept, or was mixed-case
Returns:
sdesc (str): The processed sdesc ready
for display.
