I have six buttons on a frame. When a user presses a button they are sent to a new frame with information - then they click another button and return to the first frame with the six buttons. I want to be able to check that each button has been pressed, and if it has, I want to set the alpha (since they are MC’s) set to 50%. I have done some research on this and have found that using an array is helpful. But how would I set this up?

buttons = [“btn1”, “btn2”, “btn3”, “btn4”, “btn5”, “btn6”];

But what AS would I use to check which button is pressed and where whould I put this code…on the first frame?

Thanks
