Hi everybody:
In order to implement with BJS a kind of joystick behavior simulation, that is a cylinder-like object which remains always fixed in one of its endings, and is free (draggable) in the other one, I'm doubting about what could be the best approach:
to do all the thing with basic BJS maths;
to use a transparent constraint-like sphere, with a radius equal to the length of the stick, so I can detect the picking intersection with the sphere and to orientate the stick accordingly (longitudinal axis) as I dragging it;
to use a physics-engine, maybe with a distance Joint (is this an overkill?).
Any help?
