thank you for your help, now i know how to execute the random commands,
if i wanna execute the specific commands.
EG. in Zmud, we can use #case @action {fill skin} {drink skin} {drop skin}, the commands depends on the parameter @action, how can i do it by Lua? still use Math.XXX?
please do not use Function "if elseif" that makes the scripts too large. Do we have any other simple short ideas?

The answer is actually the same, just without generating a random number.


commands = {"fill skin", "drink skin", "drop skin"}
action = 1
commands[action]

This will always result in "fill skin"

The logic is that I have built a list of commands to choose from on the first line, and then I select which one of those commands to use. In my first answer it was selected randomly.

A combination of both answers for clarity is:


commands = {"fill skin", "drink skin", "drop skin"}
action = math.random(#commands)
commands[action]

You can use the Send or Execute functions to send the random command to the MUD. "Send" literally sends the command, "Execute" treats it as if you had typed it (so if "fill" was an alias, for example, then that alias is processed).

eg.



commands = {"fill skin", "drink skin", "drop skin"}

Send ( commands[math.random(#commands)] )

Put together as an alias:


<aliases>
  <alias
   match="test"
   enabled="y"
   send_to="12"
   sequence="100"
  >
  <send>

commands = {"fill skin", "drink skin", "drop skin"}

Send (commands[math.random(#commands)])

</send>
  </alias>
</aliases>
