Unrealscript splitting a string
- by burntsugar
Note, this is repost from stackoverflow - I have only just discovered this site :)
I need to split a string in Unrealscript, in the same way that Java's split function works.
For instance - return the string "foo" as an array of char.
I have tried to use the SplitString function:
array SplitString( string Source, optional string Delimiter=",", optional bool bCullEmpty ) Wrapper for splitting a string into an array of strings using a single expression.
as found at http://udn.epicgames.com/Three/UnrealScriptFunctions.html but it returns the entire String.
simulated function wordDraw() {
local String inputString;
inputString = "trolls";
local string whatwillitbe;
local int b;
local int x;
local array<String> letterArray;
letterArray = SplitString(inputString,, false);
for (x = 0; x < letterArray.Length; x++)
{
whatwillitbe = letterArray[x];
`log('it will be '@whatwillitbe);
b = letterarray.Length;
`log('letterarray length is '@b);
`log('letter number '@x);
}
}
Output is:
b returns:
1
whatwillitbe returns:
trolls
However I would like b to return 6 and whatwillitbe to return each character individually.
I have had a few answers proposed, however, I would still like to properly understand how the SplitString function works. For instance, if the Delimiter parameter is optional, what does the function use as a delimiter by default?
