How do I hide all buttons of same class when one of them was clicked?

I have a code that should hide each button of class button1 when just 1 of them is clicked.

TOUCH on click Button1

Subevent: For each button1 : button1.visible = false

Above does not work, I need to trigger a variable for hiding these inside another event, any other solutions to make code more clear?

Touch On Touched Button1 picks one instance of this object. So inside this event any actions will be performed only on that one instance. If you need to make all other instances invisible, use "System Pick All" in a sub-event. And you don't need "For each" loop.

System Pick All Button1 -> Button1 set invisible.
