Enumerations.

[RestInPieces]

Okay, lets say I've got an enum eMusicBand declared:

enum eMusicBand
{
BAND_SickOfItAll,
BAND_BadBrains,
BAND_MinorThreat,
BAND_Cro-Mags,
BAND_Fugazi,
};

I've got a eMusicBand variable 'CurrentBand' and I've got a button in a UWindow, and now, if someone clicks the button, I want 'CurrentBand' to take the 'next' value, e.g. if CurrentBand==BAND_BadBrains , this would be BAND_MinorThreat. Is there a way to do this, except, of course, to write a long switch statement like

Switch (CurrentBand)
{
Case BAND_MinorThreat:
CurrentBand = BAND_CroMags;
break;
...
}

I mean, something like CurrentBand++ (doesn't work of course), I thought this should be possible, since each item in an enum does have an int value...
Thanks in advantage,

Write a long If statement.

I did. What a work

[JoeWang(Kage)]

CurrentBand++ should work. Have you tried it? After all, enums are stored as a byte. Maybe you would have something like (CurrentBand++) % 5 to cycle through the enum without leaving its range.

...and if that doesn't work, you can always write something like this:
local byte tempb;

tempb = CurrentBand;
tempb++;
CurrentBand = tempb;

Or a long if statement.

I agree with JoeWang. It should work just like a byte value. An enumerator is just a fancy way to work with constants instead of abstract numbers. Here's how to properly cycle through that list using the technique he mentioned. I hope it works.

if (CurrentBand==BAND_Fugazi)  //the last band in your enumerator
{
   CurrentBand=BAND_SickOfItAll;
   //which will be changed to the first one in your enumerator
}
else
{
   //otherwise, you just need it to be changed to the next one in your list
   CurrentBand++;
}

I tried both solutions, the CurrentBand++ one ("...types are incompatible with ++") and the CurrentBand=tempb one ("... bad expression in '=' "). Casting didn't work either

That's not possible... I KNOW you can assign byte values to enums - it's even done in the UT code for the ChallangeHUD, when setting Canvas.Style! So why the hell can't you assing enums to bytes?! Damn UScript.
Damn... that sucks.

Canvas.Style is a byte variable, so in fact an enum value is being assigned to byte, not vice-versa. The opposite seems not to work, though (i.e. casting a byte to an enum).
why is life so difficult...... ?
