I was searching through the old topics and I didnt found it anywhere so I post.
My question: Is there a way how to change the gray (inactive) appearance of GUIS while the script is running? I would like to keep them the way they look like when in active mode (clickable).
You couldn't have looked very hard. I found several threads, this one (http://www.adventuregamestudio.co.uk/yabb/index.php?topic=22833.0) sums it up best.
