How do I add a DirectionIndicator via C# script?
I've created a Cube and Sphere GameObjects and have the HoloLensCamera and Cursor from the HoloToolKit.
If add a DirectionIndicator component to the Sphere through Unity and configure the Cursor and Direction Indicator Object in the Inspector, the DirectionIndicator works when I deploy to my HoloLens.
However if I use the following code, instead, I get an exception at run-time (the code is in the Start method of another component):
var sphere = GameObject.Find("Sphere");
var directionIndicator = sphere.AddComponent<DirectionIndicator>();
var cursor = GameObject.Find("Cursor");
directionIndicator.Cursor = cursor;
directionIndicator.DirectionIndicatorObject = GameObject.Find("Cube");
Here's the exception I get:
Exception thrown: 'System.NullReferenceException' in Assembly-CSharp.dll NullReferenceException: Object reference not set to an instance of an object. at HoloToolkit.Unity.DirectionIndicator.Update() at HoloToolkit.Unity.DirectionIndicator.$Invoke9(Int64 instance, Int64* args) at UnityEngine.Internal.$MethodUtility.InvokeMethod(Int64 instance, Int64* args, IntPtr method) (Filename: <Unknown> Line: 0)
If I add directionIndicator.Awake(); then that seems to fix the issue. Is that okay to do? Is there something else I should be doing instead? I'm new to Unity and HoloLens.
Thanks in advance!
