Could you be more specific about how it didn't work as you would like?
Sure, let me try to explain better....
at that moment, all I want is to move a disc (buck), as in a game of air hockey, but without the disc that is in the hand of the match. He would be invisible in the case. I want to see only the buck on the screen.
With the help of TheDom, I already managed to put the buck and the disk (which is still visible) already play it with the movement of my finger. But the buck is moving alone on the screen, and if I put the speed to 0 as suggested, the disc don't hit the buck.
Forgive me for so dumb questions, but I'm learning to use the program, and I did not find examples of this in any tutorial or in the forum.
I'll have more questions after that, but to start, if I could it already be the beginning of learning.
