| Hi guys. I'm trying to make an alias that generates a random number and keeps it for the duration which the alias processes the send box, so basically, each time the alias is called, a random number is generated, and is used only once, and each time the alias is called again, a new random number is generated.
Basically, the alias uses a random number to pick an element from two basic tables and uses it. So, here's what I have to define the variable:
world.SetVariable("num", "[math.random (1, table.getn (prefix))]")
prefix is a table like so
local prefix =
{
"num1",
"num2",
"num3",
etc
"numlast"
}
and the number is used as such:
Send ("buddy chat " .. prefix [num] .. " %1 " .. suffix [num])
where suffix is a table of identical size as prefix. So the result would be like, if the random number were 1, {Buddy Sparafucile} (prefix element 1) text (suffix element 1)
Now, world.SetVariable("num", "[math.random (1, table.getn (prefix))]") doesnt seem to be doing the math.random bit, because when I call the alias, I get this error:
[string "Alias: "]:39: attempt to concatenate field `?' (a nil value)
stack traceback:
[string "Alias: "]:39: in main chunk
I might be doing something stupid with brackets or something, but I'm kind of stumped. Can anyone help me out? Thanks! | | Top |

| You don't want to quote the calculation.
num = "[math.random (1, table.getn (prefix))]"
print (num)
This prints: [math.random (1, table.getn (prefix))]
You want:
num = math.random (1, table.getn (prefix))
print (num)
