Load random animation frame

Hi, I'm a C2 newbie... I have a project that requires a button to be clicked, that when clicked will look through the entries in an array, all of which are set to either 0 or 1 (i.e. inactive/active) and randomly pick one of the entries that is active.

Then, take the array position of that entry and use that to set a frame on a sprite.

For instance, if there's an array with a width of 5, (0,1,2,3,4) and they are set to values of (0,1,0,0,1)... it should select at random either array entry 1 or 4, and then set the image frame to frame 1 or 4.

How can I do this? I've tried a bunch of times in various ways but it never works right for me.

One option would be to duplicate your initial array, and randomly pick an index up to the width. Grab that value and use Array.Delete(x) to remove that entry. Decrement your width value, and then do it all again. You'll eventually end up with nothing left.

Psssst!
