I have a play button on my game and when i touch it i would like the image opacity to change or something just so that the user knows they have touched it.

You can animate the button opacity inside the function which is executed when the button is pressed,

UIView.animate(withDuration: 0.2) {

sender.alpha = 0.5

}

UIView.animate(withDuration: 0.2) {

sender.alpha = 1

}

where sender refers to the UIButton.

The easiest way to change opacity in is to use the UIView alpha property like so:

yourView.alpha = 0.5 // 50% opacity
yourView.alpha = 0 // 0% opacity - completely transparent
yourView.alpha = 1 // 100% opacity - completely opaque
