I came to this video in august when I first started, I was too new to unity. Now it's great to come back to this with a good enough understanding to follow through :D

[@khmaieshassen]

was expecting the same result like in the instagram post 😞

[@AxisMundiOnline]

Nice one!

[@chloefyvieadams]

Amazing tutorial thank you so much 🙏 any way to make an audio trigger linked to the gaze interaction so when you look at object it makes a sound. Really appreciate all you do!!

[@sexypotato]

Bravo!!!

[@aboziad100]

i wanted to ask in the first example in the video you have shown corona information's, is those information's connected to data base can be in real time? can i connect my AR to a data base please, so the reading will be real time? thanks a lot

[@mohammadrasoulfard-habibi3066]

Great tutorial mate. Where did you learn all the c# coding from? Any tips or in-depth tutorials on this would be greatly appreciated.Thanks in advance

[@sbvf]

life saver

[@ZacharyAghaizu]

Thank you for this, but in my unity 2020 I get this error when trying to run "Recursive Serialization is not supported. You can't dereference a PPtr while loading. (Constructors of C# classes may not load objects either. See stacktrace.)" does anyone know why. I tried deleting everything, maybe the actual scene has all the errors

[@jaylee783]

Is it possible to explain how it was 3D puzzle us states model converted with Blender so they could be moved independently as in a video, please

[@ecarttop6955]

Hi , very good tutorial , i wonder can we spawn the cube by turnin it to prefab and place it on script Place On Plane ?

[@arouareads]

For map visualization what API did y use please

[@hiabex]

I'd be interested to just get gaze control to press a UI button to trigger an event such as 'loadNextScene' for Unity VR. You'd be amazed how much time can be lost just trying to find out if that's still a thing in 2021. Would this video help?

[@datasciencesagemode5691]

This is awesome. Which Augmented Reality headset can I buy and use ?

[@RajrkSunny]

It's really amazing how you did this, I saw this cool video on Linked in and I immediately subscribed to your channel. One quick question, can we export this AR as USDZ(apple's format) in unity?......Thanks

[@erjuanjojj]

Very nice, but putting the lerp in the update of each info object is necesary? I would use a coroutine. And also is Lerp correctly used? it is meant to interpolate between to numbers, and the last parameter is meant to be a percentage between 0 and 1, you are using it other way.

[@userunidentifies7610]

@Matthew, The type or namespace name 'InfoBehavior' could not be found -error . Plz help Used System.Linq also

[@gamermclife2717]

😁Dude still doing some amazing stuff. #YoungStark

[@ThirdAurora]

love you bro!!

[@oussamamorkache2560]

Amazing thanks, Is it possible to explain how it was 3D puzzle us states model converted with Blender so they could be moved independently as in a video, please

[@anirudhnv7389]

just download a vector of the map and export as svg to blender. there convert it to mesh and extrude upwards. that should do it

[@fahrulvre]

can this tutorial use for vuforia unity?

[@ashishbagul6283]

Hi how do I make it work for an image. For eg if I look at image then info about it pops up

[@user-sw5sn8vz4u]

Hi, I got this error: Field 'InfoBehaviour.SectionInfo' is never assigned to, and will always have its default value null I did drag SectionInfo into script Section Info... And the SectionInfo can't be seen in play mode, why is that?

[@igerbil3609]

I'm getting this error from the gaze script! The type or namespace name 'Raycast' could not be found (are you missing a using directive or an assembly reference?)

[@GeospatialTechnologies]

Please, I am trying to build an AR app using Unity. I have ten images and ten URL links to websites; I need to link the ten images with those ten URL links. Simply, when I scan the image with the phone's camera, I want the URL to open directly. Could you help me by explaining how can I do that?

[@poojab3272]

can I use Vuforia ar camera for the plane detection and then when the user touch it the model will appear and then the gaze interaction will be happen is it okay to do this .. or can i do this?

[@codingengineer1487]

Hey! I am new to AR/VR Can anyone please tell me how I can learn all these coding stuffs? I face too many problems due to this.

[@youssefbenbrahim3116]

Awesome work as always, please can i get some help on the previous chart video. i did all the code the same, and i had this error, how can i fix it ?? Format exception : input string was not in the right format.

[@ThirdAurora]

are you using a different API than what I used in the video?

[@zhangmomeo2193]

Can we use ARFoundation to make an AR multiplayer game? I think it will be COOOOOL if I can shoot the virus in the air with my nephew.

[@rohith6xt]

sir, does this work on redmi note 4....?

[@simonesanna674]

hi guys, I have a problem with gaze script: error CS1061: 'InfoBehaviour' does not contain a definition for 'CloseInfo' and no accessible extension method 'CloseInfo' accepting a first argument of type 'InfoBehaviour' could be found (are you missing a using directive or an assembly reference? I saw the video many time, I read the script many tima but i dont find the problem. can you help me?

[@joshwa2264]

Can you do this with vuforia?

[@sreerajr7895]

Thats an amazing work.I have a question ... how was the map made.. is it a set of 3d seperated models which was made for this or available for free any where. it will be really helpful if somebodh share the assets link or some good quality 3d model websites where i can get such models.

[@prashantdesani]

Hey, I'm also looking for this map. If you find it somewhere please share it here.

[@rohitbrr]

wait. where did that gaze script come from

[@stuileblank]

Does it work in vuforia??

[@itayhilel2168]

Make a video on how to make the falling cubes

[@sohanidas2911]

Can you show an example how to tap on a 3d object to show some info on a panel? Would be really helpful. Thanks

[@dutavirapradhanadipa7247]

Hello, did you find it?

[@stute_01]

Thank you Young Stark ; ) for the Face camera Script,, However the Gaze script isn't working,..

[@ahadali3908]

Woah! Amazing!! But like, The sign doesn't go away when I face something that's not a cube. Like you showed in the part 16:55. The last popped up sign persists. Any fixes??

[@joshuadanieldsouza]

hey in my unity editor scene the sign doesn't pops up any suggestion

[@shahidahmed7734]

Hi, I am getting this error from your last Coronovirus API. any Suggestion please? public void GetTimeData(UnityAction callback) { error CS0246: The type or namespace name 'UnityAction' could not be found (are you missing a using directive or an assembly reference?

yeah I am on my phone now but I think at the top you need using UnityEngine.Events;

Hey @ Third Aurora, amazing tutorial and explanation. I have one question, why if i convert this GameObject into a prefab and then spawn via script with Instantiate, it does not work the interactivity?. Regards

you may accidentally write FindObjectOfType instead of FindObjectsOfType. s is missing.

Try adding "using System.Linq", it just cleared the error for me

Very nice tutorial. But I struggle with 12:02 when you press on ToList and click on Quick fix and then using system.linq; I cant find the button Quick fix nor using system.linq; the the only thing I can see at its place is Quick Actions and Refactorings... so I dont know what to do.

[@MatthewHallberg]

@@SentinelYT I will look into it soon lol no one cares about anything else.

[@camelCased]

Great. But it's not truly "gaze" - it doesn't track your eyes, but just the camera center.

[@Caio-Mendez]

I need help

[@nolangericke8136]

does anyone else have trouble with the gaze interaction

[@certeccm]

Ouch. Came here because I thought this was gaze interaction (eye tracking). It isn't, it is just raycasting from the camera position (which I knew how to do). Nice tutorial though, but not what I was looking for.
