Hi all, I am new in this forum. I saw the tutorial about the bar score. I don't know kow to create a relatione between it and an object I create (it's a balnace board tilting). I mean I want to see the bar score going from left to right in relation to the balance board tilting. How can I do it? Is there a script? I am not a programmer.
Thanks a lot
