I'm trying to convert from zMUD to CMUD, but I'm a little confused about the following...

In zMUD, if I created an alias "fl", with this value:

#VAR target %1
cast firelash at @target

... then I could, for example, "fl orc", which would cast the spell at the orc, or subsequently just use "fl" on its own, which would continue casting at the last value assigned to "target" until a new one was set.

However in CMUD, it seems to be the case that the same alias will, when used on its own, set the target variable back to blank. Is there any way to create an alias which will only change the value of a variable when followed by another word?

#ALIAS fl {
#if (%1) {#VAR target %1}
cast firelash at @target
}

Oho! This is definitely good to know, as in ZMud the #IF condition would have broke if you weren't passing a parameter (null does not equate to false). Now I won't have to test for null all the time.

So whats with %null then?

#IF (%null(%1)) {}

Mine was probably lazy. If he's gonna attack something called 0 or FALSE then my example would go odd. Caled's is probably more correct

i always used %len(%1) in zmud cos it was an easy way to check, and later you could make it do even more detailed checks like, %len(%1)>3 and stuff incase you wanted minimum of x chars input

There will always be uses for %null because 0 and "" are both false but only 1 is null just a crude example, The change with cmud just makes it so you don't always have to explicity call %null all the time

You can also use %numparam. So:

#if (%numparam()>0) {#var target %1}
cast firelash at @target

Yes, you need the brackets.

alias: FL
value: cast firelash at @{tartemp1} %param(0)

using this will allow you to either set target or if you type fl name it will cast on that instead. Now you will still need to setup target variable, you can use something like

alias:tar
value: #var tartemp1 %1 or change to target if you want, your choice
