Unity VR Tutorial - Gaze Timer Interaction + Teleport

[@LibduP]

Very nice tutorial, thank you for the simple and clear explanations. Just in case for the viewers, if any of you got the issue that the circle was appearing on start and so broke the gaze functioning (in my case, it was breaking the FillAmount mechanic and was teleporting the Player instantaneously), just write the following line in the void Start field : imgGaze.fillAmount = 0; This forces the circle to be "unloaded" on start, and fixes it.

If Unity doesn't register the Pointer Enter event (that is, you point at the object but nothing happens), try changing the Max Reticle Distance under Main Camera -> GvrReticlePointer from 20 to a bigger number. I bumped it to 100 and everything works now!

[@xlaugts151]

Hi IRina, Good job! Thanks for sharing a solution with others and for watching

[@axramharter]

Hi! I have the same problem. When the object is far away, nothing happens. Now when I set the max reticle distance to 100 it registers that I'm looking at a certain object and "fills the circle". But the teleportation/rotation doesn't happen. Any idea what I'm missing? Thanks

[@xlaugts151]

Hi @@axramharter, Not sure what could be happening, I would have to create that again and see if I have the same error. I will try that again over the weekend and see if I can come up with something. Thanks for watching :) Cheers

[@xlaugts151]

[@takahashierik]

I followed your steps, but when I add the Teleport script there is no GameObject space to put the Player camera into. Also I'm using Unity 2017 instead of 2018 so I don't know if there is any difference Edit: nevermind, I was missing a semicolon. I'm new to coding so I still make rookie mistakes lol

Great video! just one question, i have error for the GetComponent Teleport object. Overall it looks fantastics.

[@rodrigo.cs.machado]

The circle of "GvrReticlePointer" is not synchronized with the center of the camera, making me have to aim more up or down on the object to work. The circle is "running" more than "Draw debug ray". Can someone help me?

[@andreaverna4356]

Thanks a lot! I need your help. I've created the gaze input and I can see it fills the circle correctly. Now, I have 2 spheres and through this gaze I would transfer the camera from the first to the second sphere. Therefore I've put 2 events: the first one is the gaze loading (as per your video) and then the "changesphere (transform)". It works, however if I trigger the first event unintentionally, seeing the image with the cardboard, and then I look outside to avoid the transfer, the second event will be actived anyway. How can I solve it?

[@xlaugts151]

Hey Andrea, Sorry for the delay. Do you have a discord ? You could show me what you are trying to achieve and I can help you. If you still need the help Thanks

[@ethanjarveyocampo1199]

Hello! I tried doing a gaze timer to scene transition, so I kinda just mashed what I got from both of your videos, which are pretty good imo! However, when I tried to do it, it bypasses the timer and goes straight to the next scene. I get this warning: "Using Raycaster (Raycaster: UnityEngine.UI.GraphicRaycaster, Object: Canvas). It is recommended to use GvrPointerPhysicsRaycaster or GvrPointerGrahpicRaycaster with GvrPointerInputModule. UnityEngine.Debug:LogWarning(Object) GvrPointerInputModuleImpl:CastRay() (at Assets/GoogleVR/Scripts/EventSystem/InputModule/GvrPointerInputModuleImpl.cs:215) GvrPointerInputModuleImpl:Process() (at Assets/GoogleVR/Scripts/EventSystem/InputModule/GvrPointerInputModuleImpl.cs:109) GvrPointerInputModule:Process() (at Assets/GoogleVR/Scripts/EventSystem/InputModule/GvrPointerInputModule.cs:184) UnityEngine.EventSystems.EventSystem:Update() (at C:/buildslave/unity/build/Extensions/guisystem/UnityEngine.UI/EventSystem/EventSystem.cs:377) ". Could this be the problem?

[@takahashierik]

How can I hide the reticle when not interacting with an object?

[@xlaugts151]

The reticle pointer is part of the SDK we import so in order to do that we would have to change the RecticlePointer script and I don't recommend that. I am not sure how it could be done, but I will have a look Thanks

[@anniehepburn9454]

Thank you for the video, it's exactly what I am look for; I am having trouble getting it working though. Is there any way you could share the 2 scripts? I'm wondering if I just copied it wrong. Thank you!
