I have made a video discussing both client and script variables, how you might create them, and how you could use them.

Thanks!

Below are the aliases I described, in case they are hard to read in the video:


<aliases>

  <alias
   match="f"
   enabled="y"
   send_to="12"
   sequence="100"
  >
  <send>
Send (left_direction)
</send>
  </alias>

  <alias
   match="k"
   enabled="y"
   expand_variables="y"
   sequence="100"
  >
  <send>kick @target</send>
  </alias>

  <alias
   match="t *"
   enabled="y"
   variable="target"
   send_to="9"
   sequence="100"
  >
  <send>%1</send>
  </alias>

</aliases>


Here are the triggers:


<triggers>

  <trigger
   custom_colour="2"
   enabled="y"
   match="* arrives from the *."
   send_to="12"
   sequence="100"
  >
  <send>

target = "%1"
direction = "%2"

</send>
  </trigger>

  <trigger
   custom_colour="6"
   enabled="y"
   match="* leaves *."
   send_to="12"
   sequence="100"
  >
  <send>

target = "%1"
left_direction = "%2"

</send>
  </trigger>

  <trigger
   enabled="y"
   expand_variables="y"
   match="@target punches you"
   sequence="100"
  >
  </trigger>

</triggers>


And here are the variables:


<variables>

  <variable name="last_direction">east</variable>

  <variable name="tank">edward</variable>

  <variable name="target">carrion crawler</variable>

</variables>

Are there some default client variables? Like for the last command sent (or last 3 commands)
In zmud it was %lastcom
Is there a list of all default variables?

There are no default variables, however quite a lot of functions that return things. For the last command, for example:

Template:function=GetCommandList GetCommandList

The documentation for the GetCommandList script function is available online. It is also in the MUSHclient help file.



An argument of 1 returns the most recent command.

Look at the function list (Ctrl+Alt+Shift+L) and type "get" into the filter window to see quite a few of them.

Some of them (like GetInfo) have a selector (argument) that returns a lot of things about the current client state, such as the world file name, log file name, how many triggers have fired, and so on.

Template:function=GetInfo GetInfo

The documentation for the GetInfo script function is available online. It is also in the MUSHclient help file.

Oh great. Thanx. GetInfo(87) works fine for me.

Now a general problem with using stuff from functions like this.
Im trying this
Send("open" GetInfo(87))
and it doesn't work. Tried moving the apostrophes and brackets all possible ways... :)

How to do it? GetInfo(87) returns "up" in my case.

Thank you

You need to read up on Lua and how it handles strings. To concatenate (join) them you use two dots, eg.


 Send("open" .. GetInfo(87))
