Vrtk: SimplePointer starts and stops interacting with objects repeatedly

[aantn]

When the "Interact With Objects" option is enabled on SimplePointer the events InteractableObjectTouched and InteractableObjectUntouched are often repeatedly called one after another when the pointer remains on the same object. If you add a highlighter to the object, you can see it flicker as a result of this.

What version of vrtk are you using? Also did you get it from git hub or unity asset store. Also what version of unity are you on?

Finally are you able to recreate the issue in a vrtk example scene and provide steps on how to recreate?

I'm using the released zip for 3.0.1, Unity version 5.5.0f3, and the latest version of SteamVR. Here are steps for reproducing this:

1. Edit WhirlyGig.cs and add a print statement to the beginning of the StartUsing function.
2. Open scene 019_ControllerInteractingWithPointer.
3. Activate the pointer and point it at Whirlygig(2) for several seconds.
4. Check the debug console. In my testing, StartUsing is called continuously for as long as you point at the Whirlygig(2) with the pointer.

Edit: This occurs with both the "touch" and "using" functionality - I know I'm only demonstrating half of that here.

@aantn confirmed bug thanks for the steps to reproduce.

I'll look at fixing it tomorrow!

That was fast :)
I won't be able to check until Friday. I'll update you then.

Thanks, that fixes the double calls to StartUsing.

Hey, I'm still experiencing a similar issue where objects are touched/untouched repeatedly. The best way I can reproduce this is by enabling the highlighter on relatively distant objects and pointing at them so that they are highlighted. The highlight (sometimes) flickers incessantly.

I can't reproduce this reliably in the sample scenes - I've seen it happen there once or twice, but I can't determine what triggers the bug. I'll keep trying.
