you’ll probably have an easier time if you first get just each small part working in isolation, away from your main project. Learning to work with arrays is important but it is confusing at first, so it’s a lot easier to do some simplified testing first.
You might setup an array that just prints strings and runs from button press in a separate project in order to figure out the iteration part. This way you don’t have any additional hijinks with the referencing different actors and so on.
