heres my problem im trying to make some trigs to calculate how many of each kind of potion i need to brew the sytanx from the mud i would recieve is...

A pouch of purple cloth contains:
a fireshield potion (27)
a blazeward potion (26)
a sanctuary potion (49)
a slink potion (9)
a protection potion (28)
a fly potion (4)
a valiance potion (8)
a demonskin potion (26)
a create spring potion (37)
an iceshield potion (48)
an antimagic shell potion (6)
a shadowform potion (12)
a shield potion (7)
a stone skin potion (6)

now what i want to do is assign just the numeric value to the variable so i can use math commands to calculate from a preset max number of each potion...like i have 27 fireshields but my variable fireshieldcur keeps popping up with a value of (27) i need the parenthesis removed from it...what ive been trying is using %replace but cant figure out what syntax i would need to do this as it doesnt recognize %p inside of the function...heres my trig so far
pattern
a fireshield potion (%*)
command
#IF (%1 = %null) {#VAR fireshieldcur 1} {#VAR fireshieldcur %replace(%1,%p,%null)}

the first part works if the (27) is not displayed it sets the value to 1...which would be correct. But if its not null i get (27) as the value of the variable...ive tried %remove as well doesnt seem to work

Try

#trigger {a fireshield potion ~((%d)~)} {#var fireshieldcur %1}

The ~ used make it so zMUD doesn't interpret the outer parentheses as an argument in the pattern to put in %1 but as an actual part of MUD output. %d will only match number and the inner parentheses assign the number to %1.

That will put the number without parentheses in your variable but just to answer your question, to remove parenthesis from something with them, you would do something like:

%replace(%replace(@VariableWithParens,"(",%null),")",%null)

still didnt work...i use this sytax for the command line
#IF (%1 = %null) {#VAR fireshieldcur 1} {#VAR fireshieldcur %replace(%replace(%1,"(",%null,")",%null))}

i need the pattern to stay the same the list might display two ways
a fireshield potion
a fireshield potion (27)
patterns wont match if i do it with quoting the parenthesis...
the sytax you gave me returned the variable value of 27)

#IF (%1 = %null) {#VAR fireshieldcur 1} {#VAR fireshieldcur %replace(%replace(%1,")",%null),"(",%null)}

played around with it this works...thanks

Hello!

I had the same issue, and oddly enough zMUD reads parenthesis as punctuation!

You can use the %p wildcard to allow the trigger to work.

#TRIGGER {a fireshield potion %p(%d)%p} {#IF (!fireshieldcur) {#VAR fireshieldcur %1} {#ADD fireshieldcur %1}}

Mind you, I'm not completely sure if the usage of the ADD command works like that. I haven't tried ;)
That should solve your trigger problem!

It appears you found a solution that works (replacing the parentheses with %null). Another solution is to use two triggers, using an end-anchor for the one without a number.
#TR {a fireshield potion$} {#VAR fireshieldcur 1}
#TR {a fireshield potion ~((%d)~)} {#VAR fireshieldcur %1}
