Unity XR Interaction Manager Bug?
Hi, I can't get interaction between XR Direct Interactor and interactable object XR Grab Interactable in my project. After simple set up. Create XR Rig with controller with XR Direct Interactor . Create an interactable object with XR Grab Interactable. I don't see a point of showing the Interactable and Hand Controllers in my scene because it is useless, there's almost everything in default state and to double check that I did the same thing on pre-build Unity VR beginner tutorial (yeah, it works there). After some debugging I determined this: Unity's XRDirectInteractor calls OnTriggerEnter upon reaching an interactable object. It calls TryGetInteractableForCollider with a collider from XRInteractionManager. The XRInteractionManager checks its m_ColliderToInteractableMap for this collider and returns an interactable object, BUT, this collection is empty. I have 2 interactable objects in my scene. And I saw how they are registered via RegisterInteractable in XRInteractionManager, they are added to the collection m_ColliderToInteractableMap of XRInteractionManager, but as I said earlier upon trying to actually get value from there the collection is already empty. I've checked and UnregisterInteractable does not get called so it's definitely not unregistered.
I am losing my mind, I did everything I could but I just can't figure out what the heck is going on. I thought maybe it's because of the New Input System in use, but I enabled option both in my Player settings and it still occurs.
Please, help.
Ok, I figured it out, debugging was helpful and I can clearly say that DON'T PREFAB YOUR INTERACTION MANAGER. At least it was something I did, I created an empty object and attached XR Interaction Manager to it and then used this prefab in my XR Rig prefab. Yep.
