i am developing an app sort of like the easy button except with multiple sounds and scenes(17 to be exact). i was wondering if there was a way to make a random scene generator so that when i hit play or tap the screen to play the next sound it plays a sound in random order and will not repeat sounds until all have been played. by the way each sound is on a different scene so right now when i press the button it changes scenes but also plays a sound. at the moment the sounds are random but sometimes repeat themselves often. Thank you to anyone who can help me out.
