How do I ...randomly choose an animation frame.

Hello all,

I know how to randomly choose a sound file using 'choose' but how would I randomly choose an animation frame? Fro example; I have an animation with 3 frames:

frame0

frame1

frame2

How would I make a randomizer to randomly select a frame from the 3 available on a button click?

Thanks so much.

This would work:

On button clicked

sprite set frame = choose(0,1,2)

Thank you so much
