What I want to do is make a script so that when you "touch" an object, it will do randomly one of three things.

I know how to do the "if .. then .. else" bit, it's the random number generator thing I'm having trouble with, to pass that random number into a variable to act on.

Does that make sense? If so, could you help me please?

Thanks.

variableName=llFloor(llFrand(3));

Should give you a value of wither 0, 1, or 2. Test it first though - I've been known to get really dumb things wrong when I've been up all night (which I have). :)

remember, too, to make this a global variable if you're going to use that value in multiple states.

Wouldn't that have the potential of sometimes (although rarely) returning a value of 3 also? Or does llFloor somehow prevent that?

There is some uncertainty on the llFrand page, but the general consensus (and just about every other RNG known to man, woman or fish) says that 0 may be generated (albeit very rarely), but 3 never will.
"0.0 <= return value < max"
