MRTK Add ManipulationHandler in C#

I'm attempting to dynamically add ManipulationHandler to child objects of a parent. The parent will be the the object the user is inspecting, but the user will be able to grap parts off of the parent and inspect them more closely. (i.e. you can look at an engine, but if you want to inspect the pistons you can grab them and look at them)

Instead of having to go into every child object and manually add it in Unity I'd like to be able to add the parent object and just procedurally add the ManipulationHandler on start or awake.

So far I have the following code, but I'm not sure how to set up the pointers so I use the script and function I want from the source:

Code (CSharp):

1. item.AddComponent<ManipulationHandler>();
2. ManipulationHandler handler = item.GetComponent<ManipulationHandler>();
3. ManipulationEvent newevent = new ManipulationEvent();
4. ManipulationEventData eventdata = new ManipulationEventData();
5. eventdata.ManipulationSource = item;
6.  

I see there's a getter and setter for Pointer in ManipulationEventData, but I'm not sure how to instantiate IMixedRealityPointer and how to get it to work.

I apologize in advance if I've missed something obvious. I'm new to MRTK.

 

I've not used any of the MRTK stuff, but if you have the top of a hierarchy of objects, you can find all sub-objects with:

Code (csharp):

1. var AllTransforms = topObject.GetComponentsInChildren<Transform>();

From there you can iterate all the transforms and decide if you want to

AddComponent<>()

to them. Note: you have to reach from the Transform to the GameObject to get at AddComponent<>();

Code (csharp):

1. foreach( var tr in AllTransforms)
2. {
3.   tr.gameObject.AddComponent<MyNewScriptToAdd>();
4. }

 

Yes, looping through child objects is not what I'm struggling with. I can loop through just fine. The MRTK script provided has a public variable of type "IMixedRealityPointer" called "Pointer", but it's an interface. So I'm not sure what to call to get the instance of it and how I would point to the script of the source it's pointing to.

 

I realize my question is more geared toward specifics of the MRTK API and don't have much to do with Unity itself.
I've re-posted my question on Stack Overflow here.

Thanks!
