[@nswell1074]

Thank you for your tutorial.But I can't understand how the virtual room matches the actual room position and rotation, can you explain it?

[@firedragongamestudio]

Very good question. The "secret" of this very simple approach is, that there is actually no real matching of room position/rotation, except for the starting position/rotation. Based on the starting position/rotation all locomotion is done via SLAM. This means the smartphone camera calculates the movement based on features found in the camera stream. If the feature detection fails or doesn't yield good results, the smartphone gyro and acceleration sensors will contribute to motion detection too. As a result, this approach works best in a feature rich environment. The next tutorial (hopefully released next week) will show how to recenter the virtual position with the help of QR code scanning, when the motion detection shifts or tracking is getting lost for various reasons. :)

[@jhngirkhn5]

Bro ARcore camera is not working on my android phone I have Vivo YT21.

[@ravinduyasith9548]

Great project! Can you explain that how the map is connected with the real world, How's the mapping works?

[@firedragongamestudio]

It's actually a 3D model out of cubes which I built, based on the real world measurements. It's "mapped" via a predefined starting point, aka where you start the app. In further videos this "recentering" will be done with QR codes and for the 3D model data you can use a scan from iPhone, Hololens or Quest3 too :)

[@dandi_saputra]

I have made a plan according to real dimensions. And the line has appeared. But why doesn't the target direction match the one in Unity? For the environment, I have rotated it based on the X Y Z axes, but...The target location does not match. My smartphone already supports arcore

It depends how and where you started. This is a very important limitation of this project.

[@poojab3272]

One more question. If i am going too use minimap. do i have to use 2 ar camera ? is it okay ?

@@firedragongamestudio thank you camera worked but the cube is not static and is moving along with the camera ...I made the target cube static but still it's moving along us ...Is there any solution for this..???

[@firedragongamestudio]

@@santoshaji6770 If you followed the tutorial everything should work. Does your device support ARCore? You can try to implement the second part of the tutorial or get the github repo too.

I just created the apk,the indicator sphere is not working properly 😅,as I move forward it moves in some other on the map and even gets out of it 😂,and the line renderer is showing path very late,please help me out

[@firedragongamestudio]

maybe your map orientation is wrong and it just looks weird ^^ hard to tell tbh

[@rajaahad1297]

how do i add AR camera in XR origin ? there is an option of camera offset and in that we have main camera , should i use that?

[@firedragongamestudio]

Pls check the GitHub repo, it's configured there.

[@kiyawo3547]

Do you have any tutorial on how to install the applications and libraries that I need and so that I can start and follow this guide? Thank you! I am currently working on a thesis and this tutorial is somewhat useful!

[@firedragongamestudio]

It's basically just Unity and the Android components (docs.unity3d.com/2022.3/Documentation/Manual/android-sdksetup.html). The rest should be covered in the setup chapter of the video :)

How do you connect with the phone device without USB? Could you may to share it? I'm currently doing similar things with your project...pliz respond

[@firedragongamestudio]

Not quite sure what you mean... I've never connected my phone without USB in this tutorial series, but it should be possible with wireless ADB.

[@user-ti6lq8uy2q]

Hello, great project, but I'm struggling for the dimension of the map, how did you resolve this problem?

[@firedragongamestudio]

One Unity unit is one meter in real life, that's the whole secret ^^

I am going to make an Outdoor and indoor navigation app AR for our campus. Im still stuck on where start? Can you help me what should I do first?

[@firedragongamestudio]

Hi, well I guess a good starting point would be to watch these 5 tutorial videos.😃For your project, you can basically use everything presented here for indoor and outdoor usage, as this implementation relies on camera footage and default smartphone sensors. The later videos will introduce QR Codes for, what I call, "Recentering", which is basically smth like an anchor for 3D data to real world points. But you'll have to create some kind of simple 3D representation of your environment, this will be a very demanding task.

How Can A search bar In Map, For Example I want Go To Starbucks InThe Mall But I dont were is he ?

[@firedragongamestudio]

Best way would be to define multiple targets (as shown in the following videos of this series) and add them into a dropdown/searchbar ui. let the user choose an option and use navigation to draw a route towards the target.

[@vedantnaikwadi5394]

which version of unity are you using which have ar origin session

[@firedragongamestudio]

It's 2021.2 in the video, but the github repo is already using 2022.3

Hi, I have talked to a couple people about this but alas no solution. When I launch the app onto an android phone for the first time it works perfectly fine, but when relaunching the app crashes afterwards. This crashing keeps occurring until I uninstall and reinstall the application. Does anyone have any idea what might be causing this?

[@firedragongamestudio]

Sometimes this can happen, when the Android version installed on the PC (check via Android Studio) and on the Smartphone do not match. But there may be various other reasons, so you'll have to eventually test it out. You can checkout the github repo (link is in the pinned comment) too and try that.

[@prabalsharma3007]

Line renderer is rendering the path very late,please help me out?

[@firedragongamestudio]

Check the next videos of this series, your problem should be fixed after the refactoring part.

[@pratishthasingh6102]

@FireDragonGameStudio If I'm making model in blender or by the same method then would there be any measurement issues? like length of the collidor or room?

[@firedragongamestudio]

as long as teh Blender settings are set to 1 unit = 1 meter and the scaling is correct -> No issues :)

[@pranavvora1691]

If I want to use this navigation app on my IOS device, all i have to do is just change my build settings to IOS?

[@firedragongamestudio]

Well, basically yes ^^ But Unity's iOS build process involves a few more steps. The ARKit XR Plugin, which should be installed via package manager, a MacOS device for developing, XCode to finally build the project and an iOS device ready for deployment. That should sum it up :)

[@dandi_saputra]

Hi I'm back again with a new problem. My Line Renderer has appeared at a minimum with a direction that is probably right for the target object. But line Renderer does not appear in my camera and indicator My sphere didn't move at all, even though I was moving in the real world. Ar foundation and Ar core have been installed according to the video😢

[@manasmj]

hey, got any fix for it?

[@firedragongamestudio]

Is your phone supported by ARCore?

[@Hao-lx3ei]

what path finding algorithm does that AR navigation use?

[@firedragongamestudio]

The Unity internal one, A" I guess.
