Bug in #IF?
|
Maybe I didn't notice some small "Don't use" text in somewhere but
| Code: |
#IF (%1 = "on") {#echo It's now %1}
#IF (%1 = "off") {#echo It's now %1} |
ain't working (%1 never matches to on/off, tried with =~ operator too).
Using 7.21. |

Used in a trigger?
#TRIGGER {The button is (%w).} {
#IF (%1 = "on") {#echo It's now %1}
#IF (%1 = "off") {#echo It's now %1}
} |

Nope, in alias
| Code: |
| #ALIAS dig_grave {#if (%1 = "on") {#var dig_grave 1}} |

Try a string compare?
#ALIAS dig_grave {#if (%1 ~= "on") {#var dig_grave 1}} |

Also, you probably need to put quotes around the %1:
#IF ("%1" = "on") {#echo It's now %1}
#IF ("%1" = "off") {#echo It's now %1}
zMUD is picky about quotes in string comparisons and remember that the %1 is a straight string replacement, so without the quotes you end up with something like:
#IF (on = "on") ...
and zMUD doesn't know that the first part is another literal string without the quotes. |

Thanks, it works now. What confused me was that if the comparable value was something else than on or off (like "jon" etc) it worked. Only on and off wasn't. |

From the expressions help file
The constants: true, yes, on are defined with a value of 1, and the constants: false, no, off are defined with a value of 0.
on is a constant that equals 1
"on" is a string that equals "on"
jon="jon" because jon isn't a constant for anything
Since you can't declare what a variable will hold in zmud (number, string, etc) you have be explicit as possible using " "s tells zmud to treat it as a string |

So I missed some information about "on" (just as I was suspecting).
Thanks to all. |
