Unity VR Tutorial - Button Gaze Timer Interaction

[@Apeles735]

Great tutorial! You should put it on your "Unity VR Tutorials" playlist, so that people can find it more easily.

[@shaycohen007]

Great tutorial, you explain it clearly and in a simple way, like your other tutorials. Please make more tutorials👍

[@xlaugts151]

Hey Shay, Thank you very much for your support!!! It really makes me want to make more of them. :)

[@freeju2001]

Thanks for t his too man. I really appreciate you for your awesome tutorials, with the help of this I would have complete my official project. Thanks a ton bro.

[@xlaugts151]

Im happy to help Manicka Raja

[@christianruiz3777]

Edit: I finally did it. Once the image is on the project You have to select the image and then go the inspecto and change the Texture Type to Sprite (2d and UI). Now it works. Thank you. For some reason, I could not accomplished it completely. The image canvas won't let me drag and drop my personalized image and neither select it. I just can select some image that are by default there -a white dot. I tried Raw Image and there I can put my personalized image but won't appear Type of image option. What could be wrong. I deleted the raycaster script but it is the same. Anyway, each tutorial you have shared have brought me big steps forward for what I knew which was zero knowledge about all this VR scene. I learned a lot. You sound like a robot which is awesome! :D PD: can you please show how to go forward by looking at the floor? and how to grab different objects. I had an idea about grabbing photos and look them near to the player and then release to grab another photo.like a photo album. I followed your first tutorial but i just can grab one photo.

[@xlaugts151]

Hey Chris, Yes I can do that. I can officially say that I'm coming back so u can expect that on the next following weeks. I let u know once I publish the video

[@dayannecristina9066]

Hey, I loved your tutorials and this one specially, it works perfectly as you showed in the video. Thank you, keep up the great job! I have a question, is there any way to hide the red circle timer as soon as the scene starts? I mean, visually, not to show the red circle timer, only when you gaze the said button. I tried some stuff and it didn't work, in my application it would be clearer if the red circle wasn't appearing the whole time if you don't click the button.

[@xlaugts151]

Hi Dayanne, Thank you very much for the nice words :) I will keep it up. To not show the red dot just adjust the fill amount to 0, on the video I did that way for you guys to be able to see. Let me know if that works for you. Thank you :)

[@dayannecristina9066]

This works great, but I can't go back to the previous scene. How do I switch back to the previous scene?

[@carlo1478]

Great tutorial, it has helped me a lot. Would you like a video suggestion? I would like to know how to control the player through a bluetooth controller in virtual reality with Unity. The movements of the head would control the camera, and the movements forward, back, left and right would be made by joystick from bluetooth controller. Can you help me?

[@xlaugts151]

Hey Carlos, I had problem trying to connect my xbox controller with my phone via Bluetooth, I will try and see if I can figure it out another way to do it. If I find it I will let you know. For the movement I have a video about it kzbin.info/www/bejne/i3PSqKR9l79sl5Y I am also creating now a tutorial on how to Jump that is going to continue from that one. Thanks for you watching :)

where can i get the scene manager ?

[@pipexo2]

hello, very good tutorial, I cannot understand in what video you show the script used in the scenemanager gameobject to change scene.

[@pipexo2]

Found the script in a comment below, Thank so much bro

[@spektrumcahaya]

Hi. Was wondering, can this work with Pico VR headset? or Vive?

[@supremebeme]

Script in video has error, if timer reaches value 2sec it will call click invoke everytime. So you have to fix this script otherwise toggle very quickly. Any suggestions?

[@supremebeme]

Just add gvrTimer=0f; before GVRClick.Invoke;

[@junio22bk]

heiii thank you very much! this is the best tutorial on the internet! you explain it very well too! little question, Same as aldi, if i delete graphic raycaster component on the canvas like you did on the tutorial, the gazing interaction won't work, but if i keep graphic raycaster component on the canvas it's work perfectly. What's the sdk version are you using?

[@xlaugts151]

Hey Junio, Thanks for you comment. I was using this version GVR SDK for Unity v1.190.1 But I am not sure if I was using that on the video hahaha.... but great that you find a solution. Sometimes the update and things that was working before it just doesnt anymore. Like on the version I was using the OnClick event does not work, so some people are not being able to reproduce some of the things I show on my videos. Cheers!

[@martinflores1774]

Hi, how i can change the size of the pointer? Not the load pointer , the pointer to select . Thanks

[@xlaugts151]

Hi Martin, First thanks for watching. To do that go to the GVR Reticle Pointer GameObject and there u will find the script attached GVRReticlePointer, open it and you will find these variables public const float RETICLE_GROWTH_ANGLE = 1.5f; public const float RETICLE_MIN_INNER_ANGLE = 0.0f; public const float RETICLE_MIN_OUTER_ANGLE = 0.5f; You can edit them and see which suits you the best :)

[@tteresajimenez]

Hi, I have a question, how can I change the selection if I have two buttons, for instance, I want that when I click button 1 a square appears but if I click button 2 the square desapears and a circle appears. Thanks, btw great video!

[@wmqspmj7208]

I already followed all the step except the plane/floor. Then my result on phone, the canvas that have button move and rotate by itself without i move the camera. The button keep moving and rotate like an Earth. How can i fix it ?

[@hagar6908]

I followed this exactly and I can't look around. The circle fills and I cant do anything else.

[@xlaugts151]

Try to add the GVREditorEmulator to the scene, that enable the controllers to look around

[@DenisTepp]

Hello! Thank you for great tutorial but I have a problem in the end when trying to change scenes. The timer is working and the circle fills with color, but it does not change the scene when it's all filled. I release the button for the camera rotation and get the error message "MissingReferenceException: The object of type 'Image' has been destroyed but you are still trying to access it." Then it gets stuck in the same scene with filled circle and does not do anything. What am I doing wrong?

[@DenisTepp]

Ah stupid me. I forgot to add it in the Build Settings for all Scenes. I tried to change the time to fill the circle and changed GVRTimer to 10 instead of 2. It slows down the filling up but also waits 10 seconds before loading the scene (circle fills still too fast and then waits for about 8 secs). How to speed up the filling process but still change the scene at the moment when the circle is filled?

[@xlaugts151]

Hey @@DenisTepp, First of all thanks for watching. To reduce the speed try to multiply the Time.DeltaTime for something like 1.5f or 2f that will speed up the fill amount. Let me know if it works

Hello! can you Help me explaining me how to create the gameObject with the script for scene change, I think I'm missing something because in the options it doesn't appear the LoadScene :(

Hi Ariana, Here it is the script: using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.SceneManagement; public class SceneChanger : MonoBehaviour { public void LoadScene(string sceneName) { SceneManager.LoadScene(sceneName); } } Once you add that script to a gameObject it's going to be a field asking for the scene name just add it and it's going to work.

[@juhainaahmed6090]

Hi. Thanks for the wonderful tutorial. I have a quesiton. How can I reset the circle to fill amount 0 once the onclick event of the button has been invoked., I am not changing the scene but may be changing the button text for example, in its onclick event. So once this is done, the filled up circle stays and does not reset to fill amount zero, so that I can gaze again at the button and see the circle fillinf up again. please help.

[@0369500]

Hey Juhaina, Thanks for asking, I found a clever solution for that hahaha... You see that our button we Invoke the event Click right ??? So on the inspector of the button you have there the field where you added the scene changer with the scene name as you can see at 6:20 of the video. What you can do is click on the plus icon to add another event when the button is clicked, then you drag the image, the red circle into it. There you will have the option to choose image > Fillamount set that to 0. What is doing is when the button is clicked it will do the action that you want plus reset the value of the fill amount to 0 and the circle disappear. Let me know if you made it work!
