    I'm stuck and can't figure out what's missing in my attempt to setup a simple controller following these simple steps from SDK Boy:
    1. Running Unity version 5.4.2f2-GVR13 & Google VR SDK for Unity v1.10
    2. Switch to Android platform
    3. Update Player Settings to using VR: Daydream and minimum API to 7.0 'Nougat'
    4. Remove Main Camera
    5. Add GvrViewerMain prefab
    6. Add GvrControllerMain prefab
    7. Create empty Player object at 0,1,0
    8. Add new Camera to Player with 0.03 clipping
    9. Add GvrControllerPointer prefab
    10. Add EventSystem
    11. Remove EventSystem's Standalone Input (fail point)
    12. Add GvrPointerInputModule to EventSystem
    13. Add GvrPointerPhysicsRaycaster to Camera
    Everything works until adding GvrPointerInputModule in step #12, which causes this repeated warning:

    GvrPointerInputModule requires GvrPointerManager.Pointer to be set.
    UnityEngine.Debug:LogWarning(Object)
    GvrPointerInputModule: Process() (at Assets/GoogleVR/Scripts/EventSystem/GvrPointerInputModule.cs:137)
    UnityEngine.EventSystems.EventSystem:Update()

    Any ideas? Thanks in advance!

    The steps you outlined in your post look correct. However, here is some guidance I can give:

    In the GvrControllerPointer prefab, there is a script called GvrLaserPointer on one of the objects. GvrLaserPointer inherits from GvrBasePointer, which calls GvrPointerManager.OnPointerCreated in it's Start method. GvrPointerManager.OnPointerCreated is what should be assigning GvrPointerManager.Pointer.

    Can you check that GvrPointerManager.OnPointerCreated is correctly getting called? If so, can you verify that you aren't setting GvrPointerManager.Pointer to null anywhere?

    Thanks,

    Dan

    Thanks for your help Dan! I follow the steps above and can consistently reproduce same log vomit every time :(

    I added some debug calls to GvrBasePointer.cs & GvrPointerManager.cs and found that the GvrPointerManager.OnPointerCreated() has a conditional statement checking if (instance != null) that is failing and indeed null.

    Not sure why or how to debug that tho.

    No problem! I think I know what is going on now. I believe you are missing the script GvrPointerManager.

    The instructions you followed were written for a slightly older version of the plugin than the version you are using. The script GvrPointerManager used to be on GvrViewerMain, but it no longer is. We added a prefab called GvrEventSystem that includes the scripts EventSystem, GvrPointerInputModule, and GvrPointerManager all together so that you don't need to set all of this up manually.

    Thanks,

    Dan

    Woot! I swapped out the manually-added EventSystem for a GvrEventSystem and it works now. Thanks!

    Hello,
    I'm trying to select an object when gazed at. I have added the GvrControllerMain prefab and replaced with it my older EventSystem, I have also added GvrGaze to the GvrControllermain. I have added an event Trigger on my target object which should call a specific function in the script but the function doesn't get called. What should I do?

    Hey Claus79!

    GvrGaze is now deprecated, I don't recommend that you use it. Instead, you should use GvrPointerInputModule which will work with EventTrigger and can be used with either the daydream controller or the cardboard reticle. More information can be found here: https://developers.google.com/vr/unity/guide

    Thanks,

    Dan

    Update Google VR from 1.0 to 1.20

    As suggested, I replaced the manually added EventSystem with the GvrEventSystem but the warning "GvrPointerInputModule requires GvrPointerManager.Pointer to be set" is still there!! :(

    I'm sorry to hear that!

    Can you verify that GvrPointerManager exists in your scene and that GvrPointerManager.OnPointerCreated is being called?

    Thanks,

    Dan

    Verified, GvrPointerManager.OnPointerCreated is not called.
    Could be just because we don't use GvrReticlePointer?
    we developed a custom script for raycast detection so we don't need it.

    If you are doing your own custom raycast detection, then you do not need to have GvrEventSystem in your scene. GvrPointerInputModule requires you to have an implementation of GvrBasePointer in your scene.

    GvrControllerPointer is an implementation of GvrBasePointer intended to be used with daydream to visualize the daydream controller with a laser pointer. GvrReticlePointer is an implementation of GvrBasePointer that is intended to be used for cardboard applications that need a reticle locked to the center of the camera.

    Some additional information can be found here.

    Thanks,

    Dan
