Leap Motion Interaction Engine Example Not Working

[windraman]

Hi ,
I have a problem to try leap motion Interaction Engine Example. The hand does not interact with the object. The console always show "NullReferenceException
Leap.Unity.ProfilerSample..ctor (System.String sampleName, UnityEngine.Object obj) (at Assets/LeapMotion/Core/Scripts/Utils/ProfilerSample.cs:31)
Leap.Unity.Interaction.InteractionController.Leap.Unity.Interaction.IInternalInteractionController.FixedUpdateController () (at Assets/LeapMotion/Modules/InteractionEngine/Scripts/InteractionController.cs:230)
Leap.Unity.Interaction.InteractionManager.fixedUpdateInteractionControllers () (at Assets/LeapMotion/Modules/InteractionEngine/Scripts/InteractionManager.cs:388)
Leap.Unity.Interaction.InteractionManager.FixedUpdate () (at Assets/LeapMotion/Modules/InteractionEngine/Scripts/InteractionManager.cs:327)"

What version of Unity and the Leap Motion core software are you using?

Faces the same issue on Unity2017.3.1f1 with 4.3.3 core software and Interaction Engine 1.1.0, then I update to Interaction Engine 1.1.1 instead, the new errors occur.

Assets/LeapMotion/Modules/InteractionEngine/Scripts/UI/Anchors/AnchorableBehaviour.cs(592,30): error CS1502: The best overloaded method match for `Leap.Unity.Utils.Map(this float, float, float, float, float)' has some invalid arguments

Assets/LeapMotion/Modules/InteractionEngine/Scripts/UI/Anchors/AnchorableBehaviour.cs(593,34): error CS1503: Argument #4' cannot convertUnityEngine.Vector3' expression to type `float'

Looks like your Core version is just sliiightly out of date; could you try upgrading to Core 4.3.4 as well as IE 1.1.1?

If you're still seeing errors I can investigate further, but I suspect the mapping functions were modified slightly in the incremental release.

I have updated both core software and IE, now it works. Thank you so much.
