How to make an object exclusively react to pinch or grab?

[Frikster]

Hello! I am using Orion for a small project.

I'm trying to create a scene with a "pinch" mode and a "grab" mode. In one mode you can only pick up blocks with pinch, the other only with grab. No other interactions should be possible with the blocks other than pinch or grab according to the mode selected (Shouldn't be able to "push" blocks around)

As it stands I have a block in a scene ad a UI element outputting the grab and pinch strength streams. I can pick up the block as you would expect and am using the Grabbing Hand script that has some magnetizing going on for pinch.

To try and "turn off" the ability to pinch pick up a block I have it so that OnReleas is called all the time via FixedUpdate. This does make it substantially harder. yet not impossible, to pinch pick up an object. How do I make it impossible so that you can only pick up an object with grab and then also vice versa, only with pinch?

Thanx

protected void OnRelease() {
if (active_object_ != null) {
// Notify the grabbable object that is was released.
GrabbableObject grabbable = active_object_.GetComponent();
if (grabbable != null)
grabbable.OnRelease();

  if (grabbable == null || grabbable.rotateQuickly)
    active_object_.GetComponent<Rigidbody>().maxAngularVelocity = last_max_angular_velocity_;

  Leap.Utils.IgnoreCollisions(gameObject, active_object_.gameObject, false);
}
active_object_ = null;

Hover();

}

It seems to me that it would be better to disable pinch in the first place rather then to constantly drop any object that might have been pinched.

There's a disable pinch function? Where?

I cant find it here or here

Is there something similar for grab? Thanx

I didn't mean to imply that this was already built-in. You will have to modify the scripts you are using to suit your application. In the GrabbingHands script, which is part of the V3 assets, the GetNewPinchState() function would be a good place to start for pinch. I'm not sure what you are using for a separate grab, but something similar should work there, too.

The key point here that you highlighted is that the "GrabbingHand" script doesn't actually define "Grabbing" (clasping an object with fingers to palm) just pinching (finger to thumb).

Messing around in the GetNewPinchState() method I gave a definition for grab and added switch statements tied to user input so that the hands become either "pinch only" or "grab only," thanx
