| I'm having a problem with a script I've been writing.
I use the following trigger to get a number in representing the number of a certain potion in a container.
^\s*(a|an)\s*(sanctuary|bless|fly|armor|protection|true|create|alertness|dispel|grounding|heal|cure|empty)\s*(blindness|poison|magic|spring|sight|)\s*(potion|flask)\s*\(\s*(\d+)\s*\)\s*$
It sends the number to a script and puts it into a variable. I created another variable:
maxLong = 1500
Then later in the scrip I compare the two like this:
if sanctuary < max long then
Where sanctuary is the number brought in from the trigger. Even when sanctuary is clearly less then 1500, it doesn't go through the if code. Can anyone help? | | Top |

| This is the classic problem of confusing numbers with strings. We can reproduce it in the Immediate window like this:
SetVariable "sanctuary", 22
SetVariable "maxlong", 1500
sanctuary = GetVariable ("sanctuary")
maxLong = GetVariable ("maxlong")
if sanctuary < maxLong then
Note "Pass"
else
Note "Fail"
end if
Run this, and it prints "Fail".
This is because it compares "22" to "1500" and thinks 22 is higher, which it is as a string. This works, converting both numbers to integer:
sanctuary = CInt (GetVariable ("sanctuary"))
maxLong = CInt (GetVariable ("maxlong"))
Other languages would have similar syntax. For example in Lua you need to use "tonumber" to do the conversion.
