- This video will show you how to get started with making an augmented reality game in Unity 2020 by setting up AR Foundation for Google's AR Core for Android, Apple's AR Kit for iOS, Windows Mixed Reality Devices, Magic Leap, and other augmented reality devices that work with Unity3d. Just choose your appropriate AR Plugin from the XR Plugin Management window. 2021 is a great time to get started with AR game development especially with the Apple Glasses, Microsoft Hololens, NReal, and other cool devices coming out on the horizon.

If you're having problems with building, try going to File / Build Settings / Player Settings / Player. Then under "Other Settings" delete Vulkan from the Graphics APIs. Also, if you're using Android, set the minimum build to Android 24.

hello how can I test my ar app realtime in unity ?
Hi i am going to bulid smart home renovation App on unity so please help me & give me your advice
I am using Unity2020.3.14f with JDK8_201U updates. It gives me multiple errors during the "Build and Run". Can you please share what combination of Unity, JDK, SDK etc. you have used on your system for this.
OK. I have resolved the issues and errors. I am sharing solution here just in case if anyone else is faced with similar problem. What I did was to lower my SDK version in Android Studio from Level 31 to 30. Installed Update for SDK level 30 (Google ARM64) and I also changed my JDK from OpenJDK 1.8_301U to OpenJDK8.1_150. I also changed Player setting in unity before build. I changed max API level from "highest installed" to Level 29. Now I have no issues. Good luck.
Would you do a video explainning the steps to connect an iPhone and also an Android tablet so we can test the thing? I have my android tablet with the developer option activated but it does nothing... Also, what would be the best way to export an app so most people can use it for free on whatever divide they have? Thank you so much! Your video is way much illustrative than the tutorials about AR in Unity website.
As a designer, this was the only Unity AR tutorial I've found that works, thanks to all sorts of things being depreciated and poorly documented elsewhere. Thank you very much, young man.
*EDIT*: I'd also really like a tutorial on using AR for something like a god game - so there's a 3d scene and you can interact with it, such as spawning different objects and colouring them using a UI. Could be pretty fun!
i actually have an updated set of tutorials that will work through 2022 if you are interested!
@@xrmasiso Hey, I am interested in those tutorials. Could you please share those?
Thanks in advance. :D
Thank for making this! I was getting a lot NullReferenceException: Object reference not set to an instance of an object.

...but it was because the AR Camera that Unity installed with the AR Origin did *not* have MainCamera as a tag. I added that tag to the AR Camera and now it works!
Nice bro! Fixed my issues
I follow every step and got stuck at 3.43 My code cant find ARRaycastManager I using VS Code Unity Editor Vertion 2021.3.16f1
Had to change ar session camera to main by changing tag. Then the raycast started working.
I get a black screen
Edit: fixed. Go to build settings and check AR Kit or AR Core
Nice Video! But I got a problem when I run my unity AR project my phone and laptop just show black screen. I have no idea how to fix this....
Do you know how to fix this.
My unity version is 2022.1.20f1.
Just like TheGreatMassacre said, this is the only AR tutorial that works. Thanks! I hope you'll make another AR tutorial with image augmentation later on.
This is mostly a great tutorial, however, I cannot get the cursor to move. I can find planes, and when not using the cursor, I can place objects wherever I want to. But when using the cursor, I can't place objects and the cursor is just placed at the start to the location where my phone was at the start of the app.
Hi I got an error saying: Assets/ARCursor.cs(9,12): error CS0246: The type or namespace name 'ARRaycastManager' could not be found (are you missing a using directive or an assembly reference?) I added ar raycast manager to the ar session origin as you said, but there is no raycast prefab shows up. appreciate your help!
hey, I got the same error. I could fix it with adding "using UnityEngine.XR.ARFoundation;" to the beginning of the code right beneath "using UnityEngine;" - maybe this helps you too!

For everyone wondering why the cursor is not moving: Tag the ARCamera of the ARSessionOrigin Object as MainCamera! Hope this helps:)
thanks, I though that my Update() not running almost half hour.

Hi, im tryng to build & run it, get no debug errors, make everything correct, but when i launch the app it crash right after unity's logo.
i'm using 2020.3.18f1 Unity and Samsung s21+ with android 11 on it.
also i'm using minimum API level to 24 and automatic for target.
Can u help me fix this?
Thanks
I am getting the same issue
Same! Did you solve this?
same problem. Do you have solution ?
for some reason it keeps saying that I can't use ARRaycastmanager since I am not using the right namespace, But when I tell it to use the right name space it still tells me it can't be found. any tips?
Same here
you added this name space exactly like this at the top of the script? (line 4)
using UnityEngine.XR.ARFoundation;
?
I did everything exactly as the video, but i keep getting a black screen. My head gears have been on this case for 2 school days now and I can't seem to figure out how to get this to work. It's not showing the phone's camera feed. I have no idea what to do anymore
I got completely lost at 3:30 when you started talking about the script. I don’t even know how that came up on the screen, but it isn’t doing that on my end
same
For some reason I get black screen every time I try to launch it. Tried a lot of things but nothing works. I really need to fix this asap, pls help!
UPD: Apparently, AR Foundation doesn't work with Unity Remote. Just building directly on my phone worked. Im kinda pissed bcs spent so much time to find solution
@@anothermadguywastaken what doesi t mean ? can you explain please ?

Thank you for this!
On 3:45, I'm having trouble to get those three slots appear as in your video.
Do you know which part I might be doing it wrong?
*When I typed public GameObject, the text GameObject didn't turn green like yours.
*Update: Saw a different comment/error from Katharina L, and her suggestion of adding "using UnityEngine.XR.ARFoundation;" solved this issue!

Nice to see a video on AR from you, I've been experimenting a few app ideas myself around this lately and I thought you explained it brilliantly! Would definitely be interested in more of this kind of content :)
Thanks, really appreciate it! I am definitely going to try to make more of these types of videos. I think it's going to be a pretty cool industry to be a part of in the future.
This does not work. The capsules don't generate or my fbx files. Joke.
new input systems might want u to try:
using UnityEngine.InputSystem.EnhancedTouch;
using Touch = UnityEngine.InputSystem.EnhancedTouch.Touch;
//if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began)
if (Touch.activeFingers.Count > 0 &&
Touch.activeFingers[0].currentTouch.phase == UnityEngine.InputSystem.TouchPhase.Began)
List hits = new List();
raycastManager.Raycast(Touch.activeFingers[0].screenPosition, hits, UnityEngine.XR.ARSubsystems.TrackableType.Planes);
Just amazing, thanks. How about an AR app where QR Codes trigger different info being displayed, including data from a web source (Like SharePoint), or step by step instructions. 1 QR code to clean coffee machine, 1 QR Code to make coffee.
Nothing spawns when I press the screen
I've gone through this tutorial starting from the AR template provided by Unity. After building from on both Mac and PC, both platforms create the cursor at the origin point and it does not update. What should I do?
I managed to fix this by changing the reference from the main camera in the script to the AR Camera by creating a reference to it and using that to cast the ray instead.
just a first dab at search querry and ended up here :) i really like what i see.. so thumbs up.. just wondering , given the age of the video, how much things could have changed in unity by now. Is this all even still compatible ??? Snappy video i liked nonetheless, thanks !
love the detail in the video. I would love to see more about making the app as well for your phone and setting it all up for a game. maybe makena mulitplayer ar game and show how it works. I hope your still making videos!
I want to try it, but my Android is still the Marsmellow version 🙂
Hey nice video.. We buit an AR app.. Can we add VR mode to that app.. Plz help..
If its a mobile app, I guess you can do a Cardboard app combination with your app? I don't even know if Cardboard is supported by Unity off the top of my head still, but I assume it is.
Thank you for the great tutorial !! You deserve more views !
Btw, I have no problem when exporting to android and the AR also works fine. Its just that the ar cursor is too close to the camera view.
Do you happen to know why ? Because I already tried to scale down the ar cursor image size to 0.05 in the inspector but still the ar cursor too close to the camera.
Weird... The only thing I can think of is the cursor is still too big or maybe you a plane wasn't detected yet so the cursor is at the origin position (which is the same position you started your phone at). Did you try the GitHub repo I uploaded? You should try that and let me know if it works for you. I can make some updates to the repo if it doesn't work because my goal was for it to work outside of the box.
And thanks for the compliment!

Still working to this day. Thanks a lot for making it only 6 minutes! I really don't need some 30 minutes video just to try out this feature. I hope you return to making tutorials!
after creating new game objects in script, no new member variable slots are populated? hmm...

How to display teks in image target produk with ar foundation
Despite scaling down AR Cursor a lot, it still looks huge on app, and nothing happens when I click it. Months ago I couldn't even make it work, it was a syntax error so probably this one's my fault too. This is a short and great tutorial, thank you very much!
Same problem here

Or make a Combat game like old console games . 1v1 fist fights .. with local 2 player VR... So two kids can compete on ar in reality!
Hi, I am trying to build an AR app using ARCore in 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?
In that case, wouldn't it be better to just imitate what a QR code does? I think you can make a script that when it scans the image, a link will show up but I don't think Unity supports an auto-open browser app for security purposes, so the user might need to click the link.
Or you could go the fancy way of making a built-in browser interface and have it opened when the user scanned the image, that way there is no need to click the link or making them open the native browser.
@@avroraflorestina2314 Thank you so much for your reply! Actually, I did it and I am sure that Unity supports an auto-open browser app. Currently, the problem is how can switch between the Links and the videos, as I have 17 scanned images; 7 images should open videos and 10 images should open links. When I scan one image the video and the link open together, but I need to open the links with the correlated images and the videos with the correlated images separately. I am stuck at this point in the C# code and I am still struggling to solve this problem. Thank you for your help!

Hello friends, I am making an application with augmented reality in unity. When I build my application for windows, the pc min camera does not turn on, how can I solve it? can you help me?
This is such a nice tutorial! Had fun playing around with it
I didn't choose universal render pipeline. Everytime I press play it takes me to a black screen even with Unity Remote. I need help.
when i place my object, the camera switches to the main camera? Any way to fix? I tried deleting the Main Camera but then cursor doesn't move
I can't get it to work as it keeps asking for Google AR which isn't for android
Hi, i have multiple object, how to add multiple object in this screen?
im havin a problem with the script. when it's put in the ar cursor i don't have extra options its all greyed out under the name. im extremely new to coding. so plz dont give me some super technical answer
Ok, but the last 10 seconds of the video didn't need to slap that hard XD
ugh this is rough.... you use os dependent code after saying its ios and android but foundation and its arrarcycast manager ar android only. then later youre typing code and the instant you get it done you blip to another screen so the viewer has to rewind and pause on the perfect time.... so stupid.
dont even get me started on your voice....

just find the camera in the hierarchy. There's a search box. Search for "cam" and you'll find it. Just delete it from there.
@@Novaborn It's very important . Because someone didn't know that. If he build that before he didn't know . He would be false.

Please help me out.....
I wonder if there is any way to maintain those position in a save file. I feel like I would probably need to set a GPS position to first origin, and whenever I load scene to offset the difference between old and new GPS position of AR origin to each placed object, am i right?.
I wish you'd make more! BEst AR tutorial I've seen yet
not working as intended😶
This doesnt work; Same problem as others in the comments. The cursor appears at origin and just sits in the same place, despite planes clearly being displayed on screen.
Update: Found from another comment - under AR Session Origin, right click AR Camera, and click properties. Then near the top of that window, under 'tag' change that to MainCamera.
why...why do you talk like that

Great tutorial. thanks. Also, How can we get only 1 object with 1 touch. I do not want to change objects position after touching the screen 2nd or 3rd times.
I haven't tested it, but you can probably try...
1) Add a new member variable
private GameObject placedObject;
2) Change the Update to:
void Update()
{
if (useCursor)
{
UpdateCursor();
}
if (objectToPlace != null && Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began)
{
if (useCursor)
{
if (placedObject != null)
{
Destroy(placedObject);
}
placedObject = GameObject.Instantiate(objectToPlace, transform.position, transform.rotation);
}
else
{
List hits = new List();
raycastManager.Raycast(Input.GetTouch(0).position, hits, UnityEngine.XR.ARSubsystems.TrackableType.Planes);
if (hits.Count > 0)
{
if (placedObject != null)
{
Destroy(placedObject);
}
placedObject = GameObject.Instantiate(objectToPlace, hits[0].pose.position, hits[0].pose.rotation);
