Alias Help
 
I've been using Cmud for some time already, and while I'm not a -total- novice at it, I can't begin to fathom how to do what I want to do...

Basically, I have 4 variables. leftarm, rightarm, leftleg, rightleg.

What I would like to do with these is compare their numerical values while storing the name of the variable for further use (%min just tells me what the value is, not the variable) so I could do something like...

if leftleg has the lowest value = attack left leg.

Additionally, while comparing these 4 variables, I want to remove one from the comparison based on a 5th variable (parried) that tells me which limb I can't attack, thus not attacking it.

Is this possible to do?

Something like this should work
Code:
#LOCAL $spot
$value=100
$limbs=right arm|left arm|right leg|left leg
#DELITEM $limbs @parried
#FORALL $limbs {
  $this=%concat("@", %replace(%i, " "))
  #IF ($this<$value) {
    $value=$this
    $spot=%i
    }
  }
attack $spot

Ok, it took me a little while to figure out what was happening in that (I've never used local variables before). However, I pasted that in and it doesn't seem to be holding the $spot value for 'attack $spot'. Adding #echo $spot test to the line after 'attack spot' returned ' test'. Is there a way around this?

I am guessing that my %concat is not properly allowing $this to contain a reference to the appropriate limb variable.
Throw in a '#SAY $this' to test that for me?
Not thinking of a proper way to correct that issue if so though... maybe wrap it in an %eval

Using #say $this didn't return anything, but using your code, I edited it a little to make it more understandable for me, and now it fires, but improperly..

Code:

#var limbvalue 100 100 A-Test
#var limbs {right arm|left arm|right leg|left leg} {right arm|left arm|right leg|left leg} A-Test
#DELITEM limbs @parried
#cr
#echo Values
#echo rl: @rightleg
#echo ll: @leftleg
#echo ra: @rightarm
#echo la: @leftarm
#echo removing @parried from list.
#FORALL {@limbs} {
  $this=%concat("@", %replace(%i, " "))
  #IF ($this<=limbvalue) {
    limbvalue=$this
    #var spot {%i} {none} A-Test
    #echo $this: @limbvalue}
  }
attack @spot

This outputs with:
Code:
Values
rl: 2
ll: -1
ra: 4
la: 0
removing left leg from list.
@rightarm: 4
@leftarm: 0
@rightleg: 2
attack right leg


Which should clearly return 'attack left arm' since it is 0, right? By it even echoing '@rightleg: 2', that means it returned "2 <= 0" as true, right?

That's my point.

$this=%concat("@", %replace(%i, " "))

seems to not be referencing the limb variable, when $this is itself referenced later, but giving us a string that represents the variable instead

Try it with:

$this=%eval(%concat("@", %replace(%i, " ")))

Yes! Ok, thank you so much:)

I did your change, and I also fixed a mistake I had made (<limbvalue instead of <@limbvalue) and now it works great. Thanks a bunch!

That's a very roundabout way to get the contents of each variable, and using %eval should be avoided because it's really slow. This is the proper way to reference a variable dynamically:

Code:
$this=@{%replace(%i, " ")}

Oh yes, I forgot about that method.
