Non repeating random number
I am creating a spin wheel using Articulate Storyline. I am facing a small challenge.
I have created 8 challenges with a wheel design using triggers. The wheel spins and stops on a random number, then it jumps to the allocated challenge.
On the second spin, the same number might be repeated (Although, I added a trigger for each challenge) . For example: If the wheel stops on 2, the leaner faces challenge 2. This challenge must be marked as done and the wheel must NOT stop on 2 anymore.
Is it possible to set up a "non repeating random number"?
Can anyone help me with it?
