Providing a variable offset to individual hands using the LeapXRServiceProvider

[kilianI]

What would be the best way to provide a different offset to each individual hand in unity? I came acros multiple different approaches and am not sure which one would be the best to achieve the goal to offset the physical representation as well as the interaction hands.

• Could it be enough to apply an LeapTransform to the individual hands from an ordinary script?

  Controller c = this.GetLeapController();
  Frame frame = this.CurrentFrame;

  Hand h = frame.Hand(0);
  h.Transform(new LeapTransform(...));

• Extends from LeapXRServiceProvider and overriding fixed update and update

Do I need to extends from LeapXRServiceProvider or LeapServiceProvider and adjust the frame data before it is being processed? If so at what places do I need to adjust the data?
I feel like when I just try and add an vector at a random place in the code I will break physics or interaction.

• Do I need to spawn an additional pair of hands (https://forums.leapmotion.com/t/add-an-offset-to-the-leap-hands-independently/6619/2)?
  ...?

• Creating own frames
  Creating a secondary LeapServiceProvider seems like an overkill and much harder than such a simple task should be.

Hi, thanks for your citation. I think you can write a function to achieve the offset, then use the function to process the frame data before the data is transported into the 'Dispatch' code. And define a bool parameter to control whether the function is enabled in the provider. Creating a secondary provider script is just for isolating the custom function from the original script.
