Curiosity. What happens if...

What do you you think would happen if you were in a Listen event, and you wrote this:

" if (msg >= "hello"
{
llSay(0,"Hello "+llDetectedName(0)+"!";
} "

What would using a greater than or equal sign do? Could I maybe say 'helloperson' and it would return pretty much the same thing as if it heard just a 'hello'?

Not sure if <, <=, > and >= are defined for strings.

However, you can always do something like:

integer StringStartsWith (string a, string prefix)
{
// prefix is longer than whole of string a, a can't begin with prefix
if (llStringLength (prefix) > llStringLength (a) )
return FALSE;

if (llGetSubString (a, 0, llStringLength (prefix) - 1) == prefix)
return TRUE;

return FALSE;
}

if (StringStartsWith (msg, "hello")
{
llSay(0,"Hello "+llDetectedName(0)+"!";
}

Greater than or less than comparisons can't be done on strings in LSL, you'll get a compiler error. You can always try comparing the string lengths, or something similar..

For that, you'd want something like:

if( llSubStringIndex( msg, "hello" ) == 0 )

if you use

if( llSubStringIndex( msg, "hello" ) != -1 )


you can find it anywhere in the string, not just starting position. (if you wanted). to be really really really REALLY sure to get all the hello's, you can also do llToLower(msg), "hello"

Heh okay, cool. Thanks.
