How do I pick others instance differently?

Hi,

In my game, there're 26 letters (instance of a sprite). Each insatance stand for 1 letter (A-Z).

If user tap on a letter, I will set its opacity to 60, but I want all others letters return opacity to 100 (event they're tapped to 60 before).

How could I do that?

Thanks!

My approach is usually this as one event :

- on object clicked,

- sub event store the UID in an instance variable

- sub event pick all object set opacity to 100

- sub event pick object where UID = instance var, set opacity to 60

On sprite clicked

- sub event - pick all sprites - set opacity to 100.

- sub event - set opacity 60.

On the sprite clicked event the clicked on instance is picked.

The first sub event with the pick all sprites condition picks all instances and sets the opacity.

The second sub event below it is still picked from the on sprite clicked event, so that sprite only gets changed to 60.

Thank you all! ;)
