Wow I thought I had lost all hope for an answer. Actually no, haven’t made any progress lol. So your reply comes still in time 
I think I had watched this video, but I didn’t insist probably cause I was not even sure this was the method I had to follow. Guess I will have to try it again with more focus and patience. So what you are saying is, I can make the whole tournament scheme using only widgets? Are there any limitations by using widgets instead of actors (which I believe do 100% of whatever you want them to do) ?
Thanks a lot for the answer! Really made my day.
