Lever movement with Orion

[PiMuRho]

I've been (not literally) bashing my head against a brick wall trying to do this over the past couple of days.

The basic setup is that I have a lever that I would like to be able to move gradually - think of it like a throttle lever.

Initially, I set it up so that it's a rigidbody that can only rotate in one direction (and to a limited degree) - I can push/pull it with my Leap hands, but it's very jittery, as it triggers on every collision by a part of the hand.

Secondly, I set it to automatically look at any collider (i.e. hand) that is sufficiently close to it. This works far better, but is still far from ideal.

Any advice or suggestions with this? I suspect I'm just missing something relatively simple here.

Never mind, I figured it out.

I wrote a script that instantiates an object (with a collider and kinematic rigidbody but no mesh renderer) at the end of the thumb when a pinch is detected. If this object is in range of the lever, I have a LookAt script that causes it to follow the movement of the object. When the pinch ends, the object is destroyed.

Not especially elegant, but it works.

I have a similar setup that might interest you, more suitable for large levers, like the kind that might open a portcullis or charge up Frankenstein's monster. I check the extension of each finger and use that to choose a state from an enum, just simple gestures like fist, open, point etc. Then if the palm transform is within range, and the gesture move from a non-grabbing state to a grabbing state, use the LookAt.

In my case, its a bit more complex, I set an objects position to the palm position, and have another object which scales to that object and does the LookAt, which makes a kind of virtual 4DoF joystick that is pretty effective for moving the camera in a God-view type of scenario.

@adam.wilko
That definitely sounds likes a more elegant and adaptable solution - Id be very interested if you care to share it.
