StrGetCharAt

[AnInhumer]

How can you convert the char returned by the StrGetCharAt into a string so that it can be used in the standard functions.

StrFormat(thestring, "%c", thechar);

Thank you, I hadn't thought of that.

I can understand the use of char but why not a string?
All the functions use int or string meaning the fact it returns something is useless

Someone is now going to point out why it isn't

Chars can be useful in certain circumstances since you can use ranges to find if a particular character is an upper case letter, a lower case letter, a number, etc. as opposed to StrComping a string to every single value.

It might be useful to have a substring-extracting function aswell, though.

Because AGS cannot return a string in a function, nor can strings be used directly in arithmetic expressions.
For example you cannot do stuff like:
string blah = "HAHAHA";
or
function MakeString(int num){
  string blargh;
  //blahblablabla
  return blargh;
}
You need to use the Str*() functions for string operations.

You mean something like that?:

Code: ags

function StrCopyEx(string destination, string source, int start, int length) {
  StrCopy(destination, "");
  int end = start + length;
  while (start < end) {
    char letter = StrGetCharAt(source, start);
    StrFormat(destination, "%s%c", destination, letter);
    start++;
  }
}

That would be a good one to add to the StringAdditions SM.  I found a problem with one of the functions in there anyway and just haven't updated it since fixing it.  I'll work on that tomorrow.  Erm... Later, today? :o ('Tis past midnight already?)
