Hand collision: LeapHandController

[zmeng90]

Hi everyone,

I'm working on a project that requires detecting hand collision with objects, and I know many others have asked before, but somehow I can't get the hand to be a RigidHand. I have a test sphere set up with RigidBody physics and IsTrigger set to on, and I've added the script for OnTriggerEnter to it (from another thread: here is the code from there):

private bool IsHand(Collider other)
{
  if (other.transform.parent && other.transform.parent.parent && other.transform.parent.parent.GetComponent<HandModel>())
    return true;
  else
    return false;
}

void OnTriggerEnter(Collider other)
{
  if (IsHand(other))
  {
    Debug.Log("Yay! A hand collided!");
  }
}

I'm not sure why my LeapHandController doesn't give me the option to set the physics models to RigidHand. I worked on the PinchDraw detector utility starter code, so what I have is the prefab that came with it. Any hints would be appreciated!

Bump, any hints? The object collision works fine but just not with the hand; is there any way to fix this?

I just attached your code above to a Sphere with a collider set with IsTrigger true. And this works fine.

The PinchDrawDemo scene has no physics hands. It only has the graphics hands. If you try this in the scene file \LeapMotion\Scenes\Leap_Hands_Demo_VR.unity it works nicely.

That scene has two pairs of hands, the graphics hands named CapsuleHand and the physics hands, name RigidRoundhand. You can look at the LeapHandController component in this scene to see of the two pairs are setup.
