Getting a list of folders

#1 Vern,

I think you need to call expandFilename() on any names that use the tilde.

%list = getDirectoryList( expandFilename("~/LevelScripts/global/paths/"), 1 );
echo("Directory list: ");
echo(%list);

That seems to work for me.

#2 Sweet, that did the trick. I really never know when to use expandFilename() or not, since half the time it doesn't seem to be needed.

Anyway, here is code that outputs a list of all folders in a given directory, going only one deep. (Turns out you need to pass 0 for this.)

%list = getDirectoryList( expandFilename("~/LevelScripts/"), 0 );
echo("Directory list: ");
		
%start = 0;
%index = strPos(%list, "\t", %start);
while ( %index != -1 )
{
	%numChars = %index - %start;
	%folderName = getSubStr(%list, %start, %numChars);
	echo(%folderName);
			
	%start = %index + 1; // Start of next folder name
	%index = strPos(%list, "\t", %start);
}

Turns out getDirectoryList returns all the names separated by tabs, so the code above uses various string functions and the "\t" tab character to find each individual folder name in the string that's returned.

#3 Hey Vern, this works but it leaves out the last folder in the directory. Just an FYI. :)

#4 Ahh, thanks for pointing that out! Here is the fixed version:

%list = getDirectoryList( expandFilename("~/LevelScripts/"), 0 );

%start = 0;
%index = strPos(%list, "\t", %start);
while ( %index > %start )
{
	%numChars = %index - %start;
	%folderName = getSubStr(%list, %start, %numChars);
	echo(%folderName);
		
	%start = %index + 1; // Start of next folder name
	%index = strPos(%list, "\t", %start);
	if (%index == -1)
		%index = strlen(%list);
}

#5 I think you can simplify things a bit there Vern.

%list = getDirectoryList( expandFilename("~/LevelScripts/"), 0 );
for (%i = 0; %i < getFieldCount(%list); %i++)
{
    %folderName = getField(%list, %i);
    echo (%folderName);
}

The function "getFieldCount" counts the number of tab seperated items in your string, and "getField" returns the ith field.

#6 Ooooh, far nicer. :-)
