How to make random number?

So basically you collide with a stack of cash, I want it to then add my variable of cash a random number instead of a fixed one to represent different cash amounts.

        [On Player Collision > StackOfCash]

                  [Add to cash]

                     [???]

That's what I am looking at right now, I don't know how to make the variable generate a random number between 2 numbers.

random(10,21)

but you probably want only round numbers

floor(random(10,21))

also you could use:

choose(10,15,20)

to choose one of those three amounts.

DIdn�t know about this choose-thing, really good tip :)

Learning system expressions can really help you come up with all kinds of new ideas for doing things :).
