llUnescapeURL question

Hi,

I'm currently offline (can't run 2nd life) but looking as scripts.

Can anyone confirm whether the following line would ALWAYS produce a 1 character string only? (i.e. if not it may explain a problem I'm having)

   llUnescapeURL("%" + (string)((integer)llFrand(100) + 10))

Thanks
Greg

Hmm... I would think not. That could generate unprintable characters which could screw up various functions of SL, so they probably constrained it to only printable characters.

If you want a random character, you might just have to make a string of all the printable characters.

You mean you think it may produce sometimes a string with more than 1 character Keknehv? (just to clarify you response)

Just tested it... Here are my results:

test code:

  		string test = llUnescapeURL("%0");
  		llOwnerSay(test);
  		test = llUnescapeURL("%20");
  		llOwnerSay(test);
  

When run, it results in the following output:

Object: %0
  Object:  

It would seem that if a code would generate a non-printable character, it simply doesn't translate. Further testing confirms this: 21, '!' works when unescaped.

Every escape code from 20 to 7E should work-- yes, 7E. You need to convert into hex to get the most from your random character function.

thanks very much for clarifying/testing this Keknehv - that was very kind

cheers
Greg

Good luck!

Or... here's a string containing all the printable characters.

"!\"#$%@&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~"

It's 94 characters long. I shall leave a random function for it as an exercise for the reader. (~Laziness---sleepy)
