Hi guys,
How can i do for move an arm up and down? (look at the picture for understand)
I would like that if i press a key it moves up increasing speed, and if press another key it moves down increasing speed.
If any keys is pressed, the arm remains in last position
Detail: if i keep the key pressed, the force increase more fast (up or down), and if i press key quickly, the force is more slowly.
I Hope I explained, and sorry for my bad english!
I attach the image:
