Okay, looking at writing a little trigger or possibly it would be an aliases but want it to go something like this:

DO
Random i 1-4
if i = 1 then north
if i = 2 then east
if i = 3 then west
if i = 4 then south
wait 3
LOOP

Okay, so that is cheep basic command code :P Obviously it would not look like that in zscript. I just want to make something so I can have a char walk around randomly. I'm obviously going to add a lot more to it but I don't know if there is a DO...LOOP function or a randomize function and if so, I haven’t found it in the help files. Any ideas?

Couple of ways of doing it. Easiest, allowing for a variable list:

#exec %item(@list,%random(1,%numitems(@list))

closest to what you suggested:

#case %random {north} {east} {west} {south}

If you're using the mapper you could use %roomexit to have it only try to move in directions that exist.

Heh, I don't use the automapper but honestly I don't understand the code there. :P

So, how do I do it?

Well, if you just want to choose a random direction, the #case command takes an expression as its first argument (in this case, a random number). Whatever number comes out of the expression, it chooses that number-th command to execute. If the number were 2, it'd choose the 2nd command and so on. Since it's a random number, it'll choose a random command.

The %item example takes a list and uses the %item function to extract an item from it. The number of the item is chosen at random, between 1 and the number of items in the list. Look the functions and commands up in the help files.

okay, so how about the do... loop part?

So you just want it to repeat the random movement every three seconds?

#alarm "RandomMove" {*3} {#case %random {north} {east} {west} {south}}

Then you can enable and disable it with #t+ and #t- too.

When looking at other programming languages it is a good thing to remember that Do is actually Do #Until.

I would suggest using an alarm the way Fang is though.
