I am try to make a trigger to count how many "a" in one line

as the screen show:
abisssaaaww weadnia waaa

there have 9 "a"
I used following method:
z=0
pattern:a
value:#math z @z+1

and use #sa @z to see the result,
but @z's value is 1,
how come?
how can I make it work?

thanks

if you set a trigger to just 'a' then your asking for trouble, but sence you did ask here you go:

#trigger {{a|A}(*)} {step2="";count=0
#var step1 %lower(%1%2)
#var step2 %replace(@step1," ","")
#loop %len(@step2),2 {#var step2 %insert("|",@step2,%i)}
#forall @step2 {#if %i=a {#add count 1}}
#echo %1%2
#echo there are @count a's}

probably going to have to wotk out the infinat trigger loop yourself.

I just had a Eureka moment on this problem.

Triggers only fire once per line, which is why the original trigger doesn't work. However, the fastest way to count a's is probably to remove them all from the string and compare the original length to the modified length. The difference should be the number of a's.
#TR {a} {#VAR step1 {%trim( %trigger)}
#VAR step2 {%replace( %lower( @step1), "a", "")}
#MATH z (%len( @step1) - %len( @step2))
#SAY @z}

oic~^^
I learn much from it,thx all

but there are another deeper problem,
how about if the string have color?
eg. there have 9 "a" but only 3 of them in red,
how can I make a trigger to count the right number of "a" in red?

let me give a example for understand the situation

how can I make the trigger which only count out the number of red "a"?

Change your triggers line color option to red

You might be able to do this with an ANSI-type trigger. I'm not interested in spending any time on it. I doubt anyone else is either, which is why you haven't gotten any answers. It's not that we don't understand what the problem is, it's that we don't see any point to it.

If you really care about the number of red a's, there are 3 of them in your example. I didn't need a trigger to find that out, I just used my eyes.

the point to make the trigger possible is
that's the robot checker make by game master which stop my robot working effectively in game.

the problem I meet is the trigger only fire once on each line,
and there have color words.
if I just simply capture the line and analysis the string,
I can't find out the right number of red a.
if I use ansi trigger,
it only fire once on each line,
how can I counting it?

so,is there possible to make me against the robot checker?
I am a beginner of zmud,
I am really hopeful there have some senior user can teach me more about zmud.
thanks.

A modification to LightBulb's solution.

You'll have to play with it yourself to modify it to match the colors actually used. This assumes low red and default changes to the ansi sequence.

#TR {a} {
#VAR step1 {%trim( %trigger)}
#VAR z 0
#WHILE (%len( @step1) > 0) {
#MATH Run %pos( "[31ma", @Step1)
#VAR RunEnd %pos( "[0m", @Step1)
#VAR z %eval( @z+%if( @Run>0, @RunEnd, 0)-%if( @Run>0, 5, 0)-@Run)
#VAR Step1 %copy( @Step1, %pos( "[0m", @Step1)+4, %len( @Step1))
}
#SAY @z} "" {color}

What I did to simulate your "screen show":
#SHOW a%ansi(red)a%ansi(default)alkjdflkajsdflkj%ansi(red)aaa%ansi(default)sdlkf%ansi(red)a%ansi(default)%ansi(red)a%ansi(Default)

So the trigger captures:
a[31ma[0malkjdflkajsdflkj[31maaa[0msdlkf[31maa[0m

Then it looks for runs of characters in red.

I leave it for you to develop the rest, the robot checker
will become harder and harder over time.
Edit to modify [ blue ] etc things

great!
thx a lot!

although I can't fully understand how it work now,
