UT2003 has a nice set of methods and structures defined in XGame.xUtil, but there are more common used methods and don't need to be rewritten every time somebody needs them. That's why I've started wUtils to create a package containing another set of usefull methods.

Feel free to contribute more useful methods to this package.

You are completely free to use wUtils and distribute it with your mod. You may also use only part of the code of wUtils. You are not allowed to distribute a changed version of wUtils under the same name, this is to prevent confusion.

Note: if you use wUtils in your mod, please check to this page to check if there's a newer version available before you release the mod.

Note 2: feel free to contribute methods/classes/... you think should belong into this package.

Usage

To use the methods from wUtils place wUtils in your EditPackages list.

Then call the methods via:

class'wUtilsClass'.static.method()

for example:

mystring = class'wString'.static.Trim(mystring);

Classes of wUtils

wString

function string Capitalize(coerce string S) (v101): will change "this is a string" to "This Is A String"
function Eat(out string Dest, out string Source, int Num) (v104): Moves NUM lements from Source to Dest
function string FloatToString(float Value, optional int Precision) (105): Converts a float to a string
function int InStrFrom(coerce string StrText, coerce string StrPart, optional int OffsetStart): like InStr except you can specify where to start the search.
function bool IsLower(coerce string S): check if a string is all lowercase
function bool IsUpper(coerce string S): check if a string is all uppercase
function string Lower(coerce string Text): like Caps but lowers strings
function string LTrim(coerce string S): trims leading spaces/tabs
function bool MaskedCompare(coerce string target, string mask, optional bool casesensitive): check target using mask, mask can contain the following wildcards: * for X chars, or ? for 1 char, check my source if it can be optimized. There's a a bug in this function. It's fixed with v104.

Johnny_o: Hey, I tried using wUtils cause it will handle what I need to get done, but I can't get it to work. I setup my edit packages and call the functions just like described above. Since I don't see anyone else writing anything I assume I must be the only person with this problem and I did something wrong. Anyone know what it could be?

Wormbo: "My car doesn't move, what's wrong?" ;) Can you be a little more specific, please?

Johnny_o: Sure, no problem. :) When I compile, I get the error message,

"Error: Can't find class 'wString'. I call the function I want to use like this:

// SomeClassOfMine ------------------------
 
  size = class'wString'.static.split2 (...);
 
// UT2003.ini -----------------------------
  ...
EditPackages=SkaarjPack_rc
EditPackages=OGGPlayer
EditPackages=wUtils

I thought, "maybe I didn't set it up right." I have the wUtils.u file in the UT2003\System directory. Same error. I tried changing the call to class'wUtils.wString'.static.someFunction() and that didn't do anything. I tried recompiling wUtils, and that didn't do anything. I still get the same error I listed above. Somebody, please help! :)

Mychaeel: Where is your own package listed in the EditPackages list?

Johnny_o: My own package is listed a few above it. So, do I have to put wUtils above my own package before I can use it?

Mychaeel: The packages listed in the EditPackages list are loaded (and compiled) in the order they're listed in. So, in order to be able to access classes from the wUtils package, it has to be listed before your own package.
