What's the syntax for using one variable in two triggers? I have a scenario like this:

search garden <command sent to mud
You find carrots in the garden. <mud output
gather carrots <command sent to mud
...gather gather gather spam...
You are tired of digging and rest a while. <mud output
gather carrots <command sent to mud
...gather gather gather spam...
You realize you have gathered all the carrots in the garden. <mud output

I'd like to use a trigger to capture whatever vegetable is found and dump it into a variable
Use that variable in the 'gather' command
Use that same variable again to start gathering when the mud outputs 'You are tired of digging and rest a while.'

Thanks!

Just use an ordinary variable. The command "#var myvariable newvalue" can be used to set the value, and the form "@myvariable" can be used in other triggers or aliases to pull the value.

A simple trigger is:

Thanks! How do i assign the variable using a trigger? So when the output/trigger 'You find carrots in the garden' fires,
carrot gets assigned that variable?

The trigger I posted does that.

Thanks so much! I was trying to do everything in one line and it just wasn't working! Works great now!

I've been playing with this and got it to work, and now I'm trying to expand on it. I've been reading about triggers, pattern matching and variables and trying different things but nothing has worked yet. Here's what I'm trying to achieve and what my last (failed) attempt was:

Search and find multiple things (As you dig you find carrots, spinach and onions)
put each vegetable in it's own (global) variable
use one of the variables in a command (you pick <var for carrots>)
start picking next vegetable when that one is gone
trigger:you don't see anymore carrots
command:pick <var for spinach>)

What I've tried:
Trigger: you find @veg1, @veg2 and @veg3
Command: pick @veg1

I've also tried:
Trigger: you find %w, %w and %w
Command: #VAR veg1 %1
#VAR veg2 %2
#VAR veg3 %3
pick @veg1

I obviously don't know what I'm doing and would appreciate any help you might be able to lend. thanks a bunch!

You are overcomplicating things a bit... unless you plan on reusing the variables for something, each vegetable does not needs its own variable.
These settings will cycle through all three vegetable types, and stop when the third is finished

#ALIAS getVeggies {#VAR veggies {carrot|spinach|onion};#VAR thisVeggie %pop(veggies);gather @thisVeggie}
#TRIGGER {You find (*) in the garden.} {gather @thisVeggie}
#TRIGGER {You are tired of digging and rest a while} {gather @thisVeggie}
#TRIGGER {You don't see anymore} {#IF (@veggies) {#VAR thisVeggie %pop(veggies);gather @thisVeggie}}

Actually, the way I would do it is with a single stringlist. A stringlist is several values packed into a single variable. So, assuming your mud text looks like:
You find carrots, spinach and onions in the garden.
You are tired of digging and rest a while.
You realize you have gathered all the carrots in the garden.

I would code it:

thanks so much for the input!
I have a question about shalimar's post -
the problem is, any combination of vegetables could be returned (it could be squash, beans and spinach). This line assigns the specific vegetables carrot, spinach and onion to the variable 'veggies', no?
#ALIAS getVeggies {#VAR veggies {carrot|spinach|onion};#VAR thisVeggie %pop(veggies);gather @thisVeggie}

Yes, Shalimar's example only put the specific vegetables carrot, spinach, and onion to the variable veggies. I presume he gave that as a simple example of setting a stringlist variable and left the implementation of capturing the correct vegetables to you. My example gave a method of extracting the vegetable names from the trigger phrase.

Thanks Rahab - the code you passed along is working great, and I learned a little more! The replace function is pretty cool.
