Unity AR Foundation - How To Use Google AR Cloud Anchors?

In today's video I focus on teaching you how to implement Google AR Cloud Anchors in AR Foundation by using the AR Core Unity Extensions provided by Google. This video also teaches you how to enable Google Cloud Anchor API, how to setup API Keys, how to host anchors, and how to resolve anchors.

[@jannesludtke578]

this is the most chaotic tutorial i have ever seen 😭 wtf is going on? why do you have coded almost everything before the tutorial instead of walking us through step by step and explaining on the way, what you are doing and why? I'm supprised anyone found this helpful. I don't mean to be disrespecful or harsh, I just think, this could be actually a very useful and helpful tutorial, if you would have an actual structure and take your time going through every step slowly, while you are coding. Thanks a lot for trying though, even though this is a dead end for me... you're the only one I found on youtube who seems to care about AR and actually seems to know what he's doing 😊

[@dilmerv]

Jannes thanks for your feedback man and yes I agree, my older videos need improvement and on the new ones I try my best to start from the ground up, I will re-make this video for 2022 and send you the link. Again thanks for your feedback.

[@sanaomer2828]

Did you find any useful tutorials for ar and cloud anchor ??? Cuz I'm losing my mind right here there's no useful guide online, plus cloud anchor sdk for unity doesn't work anymore and you have to setup everything yourself.

[@wimtofi5587]

@@dilmerv Heooo! thanks for this tutorial, but I am waiting for your remake of this video. When you will be uploaded this remake video, please?

[@adeebsidani9091]

@@dilmerv Hello Dilmer, are you going to create a step by step video on how to use cloud anchors, I think the video is important and there is no other on the internet but it is soooo confusing and sorry to say but one of the worst unity tutorials I watched so far.

[@glistensol]

Thank you so much for the tutorial! One question is there a way to integrate ARCore Extensions with AR Foundation 5.0.4, AR Session Origin has been deprecated, XR Origin is not assignable to ARCore Extensions -> AR Session Origin

[@neerajXR]

Keep Uploading AR Tuts ❤️👍

[@dilmerv]

Cool I am glad this was of your liking :) I have many more in progress !

[@mqa7001]

Hi Dilmer, arAnchorManager.AddAnchor(Pose); looks deprecated or obsolete, I am looking for which code we need to use now. Cloud Anchor state do not become success

[@lcd11001]

Hello FeatureMapQuality quality = arAnchorManager.EstimateFeatureMapQualityForHosting(GetCameraPose()); The quality always return Insufficient . How can I fixed it? Although I increased maxScanningAreaTime to 30s in scene. Thank you

[@muhammadsarimmehdi]

Did you get it to work using the keyless approach (I want to host anchors for 365 days and not just one day)? I get the Error Not authorized message whenever I try to host an anchor. I have created the OAuth2.0 credential and assigned my app's package name. However, it is still not working.

[@aamirbadershah887]

Did you manage to find a solution?

[@DaltonSessumes]

Thank you so much for this tutorial! I have a question for you- if my AR object that I place using cloud anchors is a video or animation, will any secondary device in a multiplayer network resolve the video or animation at the same playback time as the primary device? I.e. can we have an AR movie night where anyone who joins late is instantly at the same part of the movie as the rest of the group?

[@tylerchapman9219]

Unfortunately, cloud anchors just handle the AR pose of objects for everyone. If you wanted other synced network functionality (like synced video playback), you'd have to handle that separately via other methods. For example, after an anchor has been resolved on a second device, a separate synced network state (using unet, photon, or custom networking methods) would handle syncing the video itself. In summary: Cloud Anchor = placement, Separate Networking = syncing game states

[@adityasprojects7126]

Can u do video or tutorials on indoor navigation,, there s none online

[@dilmerv]

Sounds good thank you for your suggestion !

[@muhammadsarimmehdi]

So, I am assuming you also failed to get it working with the keyless approach. I think Google has disabled that feature in ARFoundation. Please confirm.

[@nkofr]

This is Google Cloud Anchors ARCore, so there is no support on iOS? I'm trying to figure if it's possible to share a multiplayer (photon?) AR experience that has the same spatialisation for every participant?

[@dilmerv]

Yes Google Cloud Anchors works for both iOS and Android, Azure also has a similar solution called Azure Spatial Anchors.

[@Yozzzein]

Hi saw your comment in ARcore extension's git about Linker error. How did you fix that ?

[@voropserg99]

Hey, did you manage to solve this problem ?

[@lcd11001]

your voice combine with Spanish, hard to understand. hihi. Good job, bro. Thank for your sharing!

[@olitworkowski]

Every time I get back to AR Unity development I have to use your videos because the documentation is so shit for AR development still... You always have a video on topic but please next time I come back please please create more structured tutorials. But thanks so much for doing them anyway!

[@dilmerv]

Thanks for your feedback! I will be updating some of these videos and improving them as some are very old and probably outdated.

[@olitworkowski]

@@dilmerv yes I noticed this Tutorial is a bit out of date. But its hard to keep up with the development speed. I feel like every time I get back to developing AR in unity (ever half a year) i have to relearn how things are done

[@ajononikostudio]

Just got the notification, if all is well and this tutorial finally helps me to build a cloud-based cloud anchor AR experience, then you are a saving grace to my potential project.

[@dilmerv]

That’s awesome and yes this can definitely help you with that project !

[@minhkhuephantran9007]

I did not found ARCore Cloud Anchor API in restriction API section. How could you do that ?

[@nandishrelekar9317]

First do enable ARCore cloud anchor API and then go back and check ARCore cloud anchor api ll be visible.

[@ugn]

Thanks for the tutorial, really appreciate it! I was wondering if you could do something on JWT authentification with Unity? I can't find a single tutorial on this online and having anchors stay for more than 1 day would be amazing :)

[@dilmerv]

Great suggestion! Thanks I will add this as a future video.

[@nickname8668]

@@dilmerv The JWT authentication is kind important for most AR anchor use as they need to last more than one day

[@mqa7001]

Thank you for video, I am working on! I guess ARCore Extensions is who manage data hosting any way. We didn't implement any multiplayer system like UNET or PHOTON NETWORKING. I am checking my project because it doesn't work fine, I don't know if I lost something in the process. I mean, Object positions are not the same for both devices

[@lcd11001]

yes, me too. I use latest version & the position isn't correct. I'm investigating GG example

[@ajononikostudio]

By the way, with the cloud anchor feature could AR indoor navigation be developed easier? There's pretty much no tutorials in that regard here on KZbin, or anywhere really, basically developing AR indoor navigation through AR Foundation.

[@calebbelk7780]

I am also wondering this.

[@charrystheodorakopoulos4843]

With google persistent cloud anchor AR indoor navigation itw pretty easy. i have done it with azure spatial anchors.

[@chamodweerasinghe8619]

I normally show the process of writing the code but I didn’t for this video ;) I will as I do today for future videos. Thanks for your feedback.

[@josephseger6053]

No hate, I like your content a lot. I just comprehend what is going on better that way.

[@ahmedkhaled4234]

Does anyone have the source code of the project the link does not open ? or Does anyone have a sample code to host and resolve cloud anchors? as i can not figure it out from arcore documentation

[@N1rv4shTyp3Z3r0]

As I've been searching for quite a while now for our Uni project and not successful, I'll try my luck here.. Was something like this (detecting/creating anchor points, saving them (somewhere, disk or wherever) and resolving the anchors) possible before AR Foundation 4? For some reason the AR Camera only correctly worked on AR Foundation 2 and I'm trying to figure out how to create, save and later (possibly after a restart of my app) resolve the previously found anchor. Maybe someone will see this and could provide some insights, thanks for the great video nevertheless!

[@samialfarra4275]

thank you so much . the google save the world map or just the anchor . i mean can i open second device and restore world map and anchor or only anchor in AR CORE ? i want use it in networking game ?

[@nv7287]

I needed to go to the APIs to enable ARCore Cloud Anchor API then I was able to restrict it.

[@dilmerv]

Awesome I am glad you figured it out and thanks for sharing your findings.

[@gbo10001]

Thanks for the video. Just to be sure, resolving time depend on the time of mapping before hosting?

[@gbo10001]

hi there, can i test it with InstantPreview? I want to use instant because when trying to resolve cloud anchor in a different session- the cloud anchor returns null or task -in -progress. please help

[@SKJagan-dh2ft]

Hey, have you solved the problem?

[@clifflin7149]

Is it so that now it's the same that google cloud anchor still has a time limit (24 hrs?) for its availability?

[@dilmerv]

They extended, it is now up to 365 days, however you need token authentication for anything over than a day.

[@kingrandow]

If multiple AR objects can be placed, is there a way track which one was placed?

[@dilmerv]

Yeah definitely possible I will make a new video with placing multiple objects as well as hosting them all.

How would a second device resolve a cloud anchor id? Would you need multiplayer networking in place to do this?
