No, i guess I introduced my question not correctly. What i need, is to be able somehow, when specific text objects are set invisible by a certain action, so that they become unactive, until another command puts them visible. I am asking for a way to temporarly disable/deactivate a layer or at list a text object or a family of text objects.
My problem is, that when they are invisible, sometimes you pass with the mouse over them, and you can see the mouse changing as if they where there. And they are clickable, and the player can accidentally click on them, while they are invisible.
