Letter replacement
|
Hi all. I need help with a script, and I know I've seen the question answered before, but I can't for the life of me find it :( ... I'm sorry for asking again
I'm working on this quest, where I need to talk in a code of sorts ... i need a simple script where i can replace all instances of 'a' with 'x' ... and 'b' with 'r' etc ...
each letter to be replaced by another letter ...
I'd give you the translation exactly, but i don't want the mud wizards getting mad :/
thanks for the help

Well, then, this becomes really easy with the %subchar function. Example (copied from the help entry of %subchar):
quote:
#SHOW %subchar("hello world","hl","12")
displays "1e22o wor2d" where all "h" characters are replaced with "1" and all "l" characters are replaced with "2"
#SHOW %subchar("hello world","hl","")
displays "eo word" where all "h" and "l" characters are removed (replaced with nothing.

Ok, here's the script that i wrote, and it doesn't seem to be working right .. it's giving an answer, but not the correct answer
#VARIABLE trans %-1
#SHOW ENGLISH 2 LIZARDISH: %subchar( @trans, abcdefghijklmnopqrstuvwxyz, hmincjaobepdgfrswykzxtluqv)
when i try 'hi' it should produce 'ob' ... but instead, it produces 'qb' ... q is to be sub'd for y, not h ... any ideas?
UPDATED: second attempt, better test:
#SHOW %subchar( %1, "abcdefghijklmnopqrstuvwxyz", "hmincjaobepdgfrswykzxtluqv")
when i enter 'abcdefghijklmnopqrstuvwxyz' and i got 'qgbfceaqbekdgfqklqkvutluqv'
there's a whole lot of 'q' in there ... |

Follow the example maybe?
#VARIABLE trans %-1
#SHOW ENGLISH 2 LIZARDISH: %subchar( @trans, "abcdefghijklmnopqrstuvwxyz", "hmincjaobepdgfrswykzxtluqv")
I have no way of testing it, but since the example shows quotes I'd expect unpredictable results from not using them.

this time i did use the "" and it still didn't work
Is there another way to do this? using a public version function? seems there are some problems with the %subchar function
(wrote this in an updated version of my previous post, but you had already responded :P wanted to bump my name to last posted)

As for the original problem, I'm sure it's possible but I suspect it will be a lot of work to get right. One approach would be to make two string variables, one (@string1) with the normal alphabet and the other (@string2) with the replacement alphabet. Your alias would then store %-1 to a third variable (@string3), then loop through that variable (@string3) replacing one character at a time. It would probably be easiest to save the replacement to a fourth variable (@string4). After finishing the loop, you can just "say @string4".
I suspect the problem with the %subchar function is that it loops through the first string doing a %replace for each character in turn. So "a" gets replaced with "h", but later that "h" gets replaced with "o", which gets replaced with "r", then "y", and finally "q".

This is definately a bug in %subchar. I'll report this in the Beta Forum, and since a new version is just around the corner, I expect this to be fixed very soon.
The solution for 6.16 is as LightBulb mentioned. That is why I asked what version you had, because without %subchar the script is a lot more complicated and slower.
