Variable generating a true/false.
|
Just wondering how to make the following work.
| Code: |
#var test1 "%if(1 = 2, 1, 0)"
#IF (@test1) {#echo True} {#echo False} |
In zMUD it would evaluate to a "False" but in CMUD it generates a "True."
If I imbed the code in an alias it works in CMUD no problem, I'd just like to have it in a handy place for easy editing rather then multiple copies spread throughout the package.
I'm thinking/hoping it's just a syntax issue on my part, because similar aliases work, it's just the ones that require <>= that seem to have problems.
Thank you! |

CMUD does not evaluate any variables or functions within the "" quotes. So your #IF statement is always true because @test1 contains a string value that is not blank. You should do just:
| Code: |
#var test1 %if(1 = 2, 1, 0)
#IF (@test1) {#echo True} {#echo False} |
if you want CMUD to evaluate the %if function during the variable assignment. If you are trying to create a function that will evaluate arguments later, then you can do something like this:
| Code: |
#FUNCTION test1 {#RETURN %if(%1 = %2, 1, 0)}
#IF (@test1(1,2)) {#echo True} {#echo False} |

It was the evaluate later I was looking for. I'd looked at using a function, but saw it wanted something to execute rather then just returning an evaluation. Overlooked the #return.
Thank you very much. |

Yeah, to get something like the old "inline" functions in CMUD, you use #VARFUNC. Like this:
| Code: |
#VARFUNC test1 {%if(%1 = %2, 1, 0)}
#IF (@test1(1,2)) {#echo True} {#echo False} |
See the Changes for zMUD Users topic: http://www.zuggsoft.com/kb/cmud_changes_varfunc |
