grabbing non-spherical objects more precisely

[r03ert0]

Hello! I'm trying to grab objects that have non-spherical shapes. I'd rather avoid adding the physics library (here's code showing what I'm doing).

Sometimes, however, objects are very close to each other, and I end up grabbing the wrong one. Especially for slender objects – think a very flat box – the bounding sphere is a very bad approximation of the shape, and the area of grabbing errors is as large as the largest dimension of the box.

Is there a way of having something more precise than the sphere-collider? The readme mentions using the raycaster as an alternative to sphere-collider, but I didn't find more info about that...

thank you!
