I’m making a Q and A game and I’m trying to make the questions customizable.

So if I have it to where if I type in the top left text box, it changes the one in the middle.

Now I’m trying to figure out how to change another text box while it’s off screen

So if I changed the top left on the first one, it would set the top left text box on the other widget to the same thing, but you can’t change it anymore. Please help.

First Thought is maybe creative use of the “is line of sight” node ?
