- 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.

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
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.
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.
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!
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
This is such a nice tutorial! Had fun playing around with it
I wish you'd make more! BEst AR tutorial I've seen yet
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!
Awesome video, Novaborn, thank you very much for this :)
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?.
Thank you so much! I did it today.
Thank you so much! I needed a small demo app to check if I can run AR apps on my phone. :D
lol and for this you use this tutorial instead of nstalling a ar app you are hardcore xD
@@Dodomba I had to create an AR app, so I needed to see if I can make an AR app that works on my phone 😜
Thanks for the quick and very useful tutorial. How can I hide or disable surface line edges?
It worked! Thanks
Hi,great tutorial, is there anyway to make it so it places different objects,for example first a red cube, then selecting a blue cube , and place that one, thanks :)
Had to change ar session camera to main by changing tag. Then the raycast started working.
thanks for you video, i have a question is it possible to use it for placing complex object like a house for example?
yes you can place any game object you make
Can u pls make a video on persistent cloud anchors.. Following which can u do a video on indoor navigation. I need this for one of my projects I have been trying to develop. there are no such videos online. Thanks
hey bro I want to learn AR development what should I do?
and do you have any tutorials series for AR learning for beginners?
May I ask to make an AR marker scan to launch the app?
bro, I need your help. suppose I have completed a project and now i wanna set this on a constant surface to let it be seen by everyone closer to that. so how am I supposed to do that? I mean process. Please lemme know
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
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.
Lifesaver!
Do you have any example on how to rotate the image? My target is to have a human body laying on the floor
How can I do this but with the Echo3D SDK and without those planes showing?
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
Could export for ios or android using AR Foundation without changing my code ??
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!

Same issue @novaborn. Can you explain?
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.
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
can i do it for web? or have to put the application in the phone
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.
Hi, i have multiple object, how to add multiple object in this screen?
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.
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!
@@Novaborn Hi, I tried your github repo but when I import it into an empty Unity project, it displays this error: Library\PackageCache\com.unity.render-pipelines.core@10.3.1\Runtime\Textures\TextureXR.cs(42,45): error CS0117: 'GraphicsDeviceType' does not contain a definition for 'PlayStation5'

@@Novaborn Oh I see because right now my project is not set in URP. Just a normal project without URP environment. Is it possible that could be the cause ?
4:06 how did you drag the ray cast manager to the ray cast game object? I'm having a hard time doing that haha
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. Do you have solution ?
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.
I want to try it, but my Android is still the Marsmellow version 🙂
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);
}
}
}
}

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!
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;
?
It works for me, only when I turn off URP
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
