"mod" system function to calculate remainder

Hi,

I don't see a "mod" (for modulu) system function, to find the remainder for division. Is very useful for creating additions that stay in a range. For exampe, suppose i want to create a little game that pressing a button steps through all frames of an animation. If i know that there are say animations 0 to 5, then you can use a mod function as follows:

current frame = (current frame + 1) mod 6

set animation frame to (current frame)

this will conveniently guarantee that you circle through the frames.

But, i guess there is no mod system function. Could one be offered?

EDIT@ Don't think I've got it right. >.>

thanks.

But the behavior i need is as follows:

Button pressed --> show next frame unless already at max frame, then show frame 0

I imagine loop would just loop through all frames without "waiting" for the button to be pressed. Or, is there another way to use loops?

It's the % operator.

Ahh, great! thanks. I missed the operators.

thanks.

Ok, what you need is a local variable "frame" (you can call it anything). On press the button, set "frame" to "frame"+1 and set object animationframe to "frame". And make a condition If "frame" > objects frame count then set "frame" and animation frame both to 0.

EDIT@ Oh there is the operator already. Cool.
