Throughout the larger documentation you may come across commands prefixedwith
@. This is just an optional marker used in some places to make acommand stand out. Evennia defaults to ignoring the use of
@in front ofyour command (so entering
digis the same as entering
The default commands have the following style (where
command[/switch/switch...] [arguments ...]
A switch is a special, optional flag to the command to make it behave
differently. It is always put directly after the command name, and
begins with a forward slash (
/). The arguments are one or more
inputs to the commands. It’s common to use an equal sign (
assigning something to an object.
Below are some examples of commands you can try when logged in to the
help <command> for learning more about each command and
their detailed options.
Stepping Down From Godhood¶
If you just installed Evennia, your very first player account is called user #1, also known as the superuser or god user. This user is very powerful, so powerful that it will override many game restrictions such as locks. This can be useful, but it also hides some functionality that you might want to test.
To temporarily step down from your superuser position you can use the
quell command in-game:
This will make you start using the permission of your current
character’s level instead of your superuser level. If you didn’t change
any settings your game Character should have an Developer level
permission - high as can be without bypassing locks like the superuser
does. This will work fine for the examples on this page. Use
to get back to superuser status again afterwards.
Creating an Object¶
Basic objects can be anything – swords, flowers and non-player
characters. They are created using the
This created a new ‘box’ (of the default object type) in your inventory.
Use the command
i) to see it. Now, ‘box’ is a
rather short name, let’s rename it and tack on a few aliases.
name box = very large box;box;very;crate
We now renamed the box to very large box (and this is what we will see
when looking at it), but we will also recognize it by any of the other
names we give - like crate or simply box as before. We could have
given these aliases directly after the name in the
this is true for all creation commands - you can always tag on a list of
;-separated aliases to the name of your new object. If you had
wanted to not change the name itself, but to only add aliases, you could
have used the
We are currently carrying the box. Let’s drop it (there is also a short
cut to create and drop in one go by using the
/drop switch, for
Hey presto - there it is on the ground, in all its normality.
This will show some technical details about the box object. For now we will ignore what this information means.
look at the box to see the (default) description.
look box You see nothing special.
The description you get is not very exciting. Let’s add some flavor.
describe box = This is a large and very heavy box.
If you try the
get command we will pick up the box. So far so good,
but if we really want this to be a large and heavy box, people should
not be able to run off with it that easily. To prevent this we need to
lock it down. This is done by assigning a Lock to it. Make sure the
box was dropped in the room, then try this:
lock box = get:false()
Locks represent a rather big topic, but for now that will do what we want. This will lock the box so noone can lift it. The exception is superusers, they override all locks and will pick it up anyway. Make sure you are quelling your superuser powers and try to get the box now:
> get box You can't get that.
Think thís default error message looks dull? The
get command looks
for an Attribute named
get_err_msg for returning a nicer error
message (we just happen to know this, you would need to peek into the
code for the
get command to find out.). You set attributes using
set box/get_err_msg = It's way too heavy for you to lift.
Try to get it now and you should see a nicer error message echoed back to you.
You create new Commands (or modify existing ones) in Python outside the game. See the Adding Commands tutorial for help with creating your first own Command.
Get a Personality¶
Scripts are powerful out-of-character objects useful for many “under
the hood” things. One of their optional abilities is to do things on a
timer. To try out a first script, let’s put one on ourselves. There is
an example script in
evennia/contrib/tutorial_examples/bodyfunctions.py that is called
BodyFunctions. To add this to us we will use the
script self = tutorial_examples.bodyfunctions.BodyFunctions
(note that you don’t have to give the full path as long as you are
pointing to a place inside the
contrib directory, it’s one of the
places Evennia looks for Scripts). Wait a while and you will notice
yourself starting making random observations.
This will show details about scripts on yourself (also
works). You will see how long it is until it “fires” next. Don’t be
alarmed if nothing happens when the countdown reaches zero - this
particular script has a randomizer to determine if it will say something
or not. So you will not see output every time it fires.
When you are tired of your character’s “insights”, kill the script with
script/stop self = tutorial_examples.bodyfunctions.BodyFunctions
You create your own scripts in Python, outside the game; the path you
script is literally the Python path to your script file. The
Scripts page explains more details.
Making Yourself a House¶
The main command for shaping the game world is
dig. For example, if
you are standing in Limbo you can dig a route to your new house location
dig house = large red door;door;in,to the outside;out
This will create a new room named ‘house’. Spaces at the start/end of names and aliases are ignored so you could put more air if you wanted. This call will directly create an exit from your current location named ‘large red door’ and a corresponding exit named ‘to the outside’ in the house room leading back to Limbo. We also define a few aliases to those exits, so people don’t have to write the full thing all the time.
If you wanted to use normal compass directions (north, west, southwest
etc), you could do that with
dig too. But Evennia also has a limited
dig that helps for compass directions (and also up/down
and in/out). It’s called
tunnel sw = cliff
This will create a new room “cliff” with an exit “southwest” leading there and a path “northeast” leading back from the cliff to your current location.
You can create new exits from where you are using the
open north;n = house
This opens an exit
north (with an alias
n) to the previously
If you have many rooms named
house you will get a list of matches
and have to select which one you want to link to. You can also give its
database (#dbref) number, which is unique to every object. This can be
found with the
examine command or by looking at the latest
Follow the north exit to your ‘house’ or
teleport to it:
To manually open an exit back to Limbo (if you didn’t do so with the
open door = limbo
(or give limbo’s dbref which is #2)
Reshuffling the World¶
You can find things using the
find command. Assuming you are back at
Limbo, let’s teleport the large box to our house.
> teleport box = house very large box is leaving Limbo, heading for house. Teleported very large box -> house.
We can still find the box by using find:
> find box One Match(#1-#8): very large box(#8) - src.objects.objects.Object
#dbref of the box (#8 in this example), you can grab the
box and get it back here without actually yourself going to
teleport #8 = here
(You can usually use
here to refer to your current location. To
refer to yourself you can use
me). The box should now be
back in Limbo with you.
We are getting tired of the box. Let’s destroy it.
You can destroy many objects in one go by giving a comma-separated list of objects (or their #dbrefs, if they are not in the same location) to the command.
Adding a Help Entry¶
An important part of building is keeping the help files updated. You can
add, delete and append to existing help entries using the
sethelp/add MyTopic = This help topic is about ...
Adding a World¶
After this brief introduction to building you may be ready to see a more fleshed-out example. Evennia comes with a tutorial world for you to explore.
First you need to switch back to superuser by using the
command. Next, place yourself in
Limbo and run the following
This will take a while (be patient and don’t re-run the command). You will see all the commands used to build the world scroll by as the world is built for you.
You will end up with a new exit from Limbo named tutorial. Apart from being a little solo-adventure in its own right, the tutorial world is a good source for learning Evennia building (and coding).
