Can you continue with this series? This is the very first Unity ARFoundation tutorial I have followed that isn't insanely awful. This was great, it worked, its up to date, its logical, and it goes from beginning to end without skipping steps. Signed up for your Patreon.
It baffles me as to how this channel is the only one with good and easy to understand Unity Augmented Reality tutorials. I remember watching your Vuforia tutorial about 3-4 years ago. Great stuff!

Just curious, why is everything after private readonly Dictionary _instantiatedPrefabs = new Dictionary(); and OnTrackedImagesChanged commented out, whereas its not in the video?
For those having an issue with the script compiling, try making sure the class name in the CS file is the same exact name as the CS file, casing and all.
.cs on the name to??, it didn't let me add it, got an error saying,"The associated script can not be loaded. Please fix any compile error and assign a valid script"
@@bruhbeat3047 no, don't include the ".cs" part in the script class name. Just put the name that's in front. If you still have an error, then it's probably a different syntax error so go through the code again and see if you have anything missing or in a wrong format.

Thank you so much for this tutorial! I had struggled through 5 other ones that were either out of date or broken in some way. This was so simple and friendly for an absolute Unity noob :) I'm going to use it to make AR christmas cards this year!
honestly I work with unity for a few years now as a hobby. I never touched AR and I enjoyed your video a lot. Fully understandable. Continue this great job.
This is awesome 👏🏼 As a XR teacher I will let my students make an AR gallery. Nice addition! As I planned to let them make a VR gallery already. Thanks a lot! I’ll support you.
Thanks for the excellent tutorial! Like many others, I use iOS and have had the black screen and Unity crashing issues. Some people suggest that it's resolvable with activating and updating the ARKit /ARCore. Mine were already in place and updated, and it wasn't until I downloaded and imported the entire Unity AR Foundation package that I was able to do image tracking and have the camera work. They have samples built in to the Foundation package. There are a lot more scripts!
I watched many AR tutorial on RUclips, but most of them were outdated or hard to understand. Thanks for this detailed Unity AR tutorial. I have just liked and subscribed to your channel. Would you please create a tutorial on how to rotate and scale different objects after instantiating the 3D models in the AR scene? Cheers!

Hello Playful Technology Great dowen to earth video, perfekt tempo. I made the app and it runs perfectly, the camera it's starting normally on the app at my mobile device (Samsung s21), but when I point it to the anchor image, nothing happends, the 3D object does not appear above it. Can you help me/us
Hi, I've built the app on my phone but no matter what i do it doesnt seem to be placing any objects at all. As far as i can tell i've done everything as per the video but when i open the app the camera opens but it either doesnt detect or doesnt place objects(Which one i cant tell) Are there any steps i can take to debug this?
Sorry for necroposting. Did you get it to work? At first I thought it wasn't working but then I noticed the tip of a gray cube in the corner of the screen. Then after some moving around the image I managed to get the cube to come to the screen but it's still kinda floaty and not centered.
Very good as usual. Not something I'm interested in, but I enjoy the way you go in depth on topics, which is why I subscribe. I hope you have more things like the big digit timer and Arduino/pi items. Love those. I'm sure you will. Cheers!
Yo this helped so much and I always appreciate the content and when i found the channel and got the energy from you from the previous video, you've been nothing but real and can vouch for the amazing content and how down to earth you are with everything! All the most love, respect, and appreciation
Thank you very much for this tutorial. Unfortunately I got the following error when I build the project on Android: "The application requires last version of Google Play for AR". Everything seems ok. I also tried several devices without success. Any suggestions? Thanks
THIS IS TOTALLY AMAZING. Ive always wanted to start studying AR and this was the perfect jumping off point. One question i had was where could we find the script put into visual studio at the 16 min mark?
I need some help. I was able to build & run the app, but when I point the camera at the reference, my object doesn't show up. The reference I'm using is an 8x8 grid of black & white squares which should be pretty easy to recognize, and is about 180 x 180mm for the entire grid, so decently large. I'm using a Samsung Galaxy S8.
Hi can any one assist me. When I done with coding I am receiving error in Script component in Unity as " Associate Script cannot be loaded. Please fix any compile errors and assign a value to script". But there is not error showing in Visual studio

Everything built successfully but when I open the AR app it’s having a hard time recognizing the image marker, the cube object just randomly appears and disappears does anyone know how to fix this?
all the different elents together in a language that is universal. I've seen plenty of DAW tutorials being new, but tNice tutorials is by far the best so
Hi, Nice video, Can you demonstrate a case where the augmented reality game uses objectron object detection to sense the direction of the object with respect to the movement of the object. A usecase can be there is a car toy and based on the objectron users can see certain effects like turbo and smoke based on the object velocity at the correct position i.e. at the rear always.
Whoever gave that dislike should get punched in the mouth. Great job on making a fantastic and easily comprehensible tutorial. I'm trying to add an interactive story element to my posters via AR and this was just what I needed. Thanks a million times over.
sorry when i copy and paste the cs script. it keeps saying "associated script can not be loaded, please fix any compile errors and assign a valid script". help please. update: fixed issue. the script name has to be spelt the exact same on the cs code
@@user-el5jg3wo9b I saw someone else with same issue in comments and again I know it's a bit late but I've had this issue and managed to resolve it by simply changing 0 to 1 in the AR Tracked Image Manager component that is attached to the AR Session Origin.
Hi Sir, I am very new to SDK and AR. I am confused about determining the SDK, which device is suitable for it. I always encounter errors when I want to build an application. I hope you make a tutorial about SDK and Unity 2017 because this version is the best in my opinion and the beginning of AR being implemented in unity.
Any changes to the AR Tool landscape since this video was made? For example, Flutter , ARLoopa, or Flet/ARCore ? I'd like to make an Android application that can find components from a circuit board! Just use your camera and it will overlay a marker on the component... however, not sure if there is a minimum marker size , and if it can be overlayed with such high precision. For example, if you have a sheet of paper with a grid of squares, say 50x50.. if A4 is said/entered, could AR use a fiducial on the paper to calculate how far into the grid it needs to place a marker (scaling it based on the the angle and how close the camera is to the sheet).
this is amazing, great tutorial. but what if I dont want to depend on a single device? what if I want to make it web based? working for android and IOS?
Nice tutorial brother i just want to ask you wNice tutorialch software is easy and best to learn as DAW soft soft or abelton live. Pls reply as soon as you can
I'm not sure about tNice tutorials, but if you wanna fix it open GMS. Then in the GMS, there's a light blue screen with a lot of buttons and other stuff.
For starters, congratulations for the video! great content and excellent teaching! I'm following this video for the development of a graduation project, and I wanted to integrate this project with the use of VR glasses (like google cardboard or VR Box) to visualize museum architectures in 3D. Do you have any tips on how to implement such functionality?
Is there any way to play a RUclips video as AR instead of using a video stored on device? I actually want to create an AR app that would scan over 70 different objects and display a separate video for each one. This would increase the size of the app,hence wish to fetch the videos from RUclips.
Hi, everyone. I have an issue. I made the app and it runs perfectly, the camera it's starting normally on the app at my mobile device, but when I point it to the anchor image, nothing happends, the cube does not appear above it. Does anyone knows how I fix that, pls?
Maybe too late but I still leave here a comment in case someone would wondering. In your scene you have another objects that comes with newer version of Unity, such as UI or some Inputs/Events. You should have only AR Session, AR/XR Origin and a light in your scene.
Hello, sorry for the translation via Google. When you are explaining about the event handler, is there a foreach that goes through the trackedImage variable where it is fed? Sorry for the stupid question, I program in PHP/Jquery some things are very familiar others I'm a little confused.
I wanna ask for the tracking of the images, is there any limitation where by the colour must match? lets say the image library we gave a colour image but we track a monochrome image. Does it work?

Thankyou my man
Can you continue with this series? This is the very first Unity ARFoundation tutorial I have followed that isn't insanely awful. This was great, it worked, its up to date, its logical, and it goes from beginning to end without skipping steps. Signed up for your Patreon.
I wish he would continue too !
Most of what you'd do isn't specific to AR. Physics triggers, scenes, raycasts, all basic Unity stuff.

@@bruhbeat3047 no, don't include the ".cs" part in the script class name. Just put the name that's in front. If you still have an error, then it's probably a different syntax error so go through the code again and see if you have anything missing or in a wrong format.

Thank you so much for this tutorial! I had struggled through 5 other ones that were either out of date or broken in some way. This was so simple and friendly for an absolute Unity noob :) I'm going to use it to make AR christmas cards this year!
honestly I work with unity for a few years now as a hobby. I never touched AR and I enjoyed your video a lot. Fully understandable. Continue this great job.
The most structured and detailed tutorial i ca across until now. Thank you very much!
This is awesome 👏🏼 As a XR teacher I will let my students make an AR gallery. Nice addition! As I planned to let them make a VR gallery already. Thanks a lot! I’ll support you.
Fantastic! Your explanation for the C# segment is clear and surprisingly simple - thanks!
Thanks for the excellent tutorial! Like many others, I use iOS and have had the black screen and Unity crashing issues. Some people suggest that it's resolvable with activating and updating the ARKit /ARCore. Mine were already in place and updated, and it wasn't until I downloaded and imported the entire Unity AR Foundation package that I was able to do image tracking and have the camera work. They have samples built in to the Foundation package. There are a lot more scripts!

man I missed this kind of tutorials lol. Great work here, thanks!!!
Hi, I've built the app on my phone but no matter what i do it doesnt seem to be placing any objects at all. As far as i can tell i've done everything as per the video but when i open the app the camera opens but it either doesnt detect or doesnt place objects(Which one i cant tell) Are there any steps i can take to debug this?
I am having the same issue, any resolution??
I've got the same issue. I do everything step by step, but camera not detect my reference image :( Samsung S21
Sorry for necroposting. Did you get it to work? At first I thought it wasn't working but then I noticed the tip of a gray cube in the corner of the screen. Then after some moving around the image I managed to get the cube to come to the screen but it's still kinda floaty and not centered.

Hi, Nice video, Can you demonstrate a case where the augmented reality game uses objectron object detection to sense the direction of the object with respect to the movement of the object. A usecase can be there is a car toy and based on the objectron users can see certain effects like turbo and smoke based on the object velocity at the correct position i.e. at the rear always.

Hi Sir, I am very new to SDK and AR. I am confused about determining the SDK, which device is suitable for it. I always encounter errors when I want to build an application. I hope you make a tutorial about SDK and Unity 2017 because this version is the best in my opinion and the beginning of AR being implemented in unity.
Cool stuff as usual. I like it.
videos on pretty much everytNice tutorialng. Feels like I can finally move forward with making soft.
thank you so much man. love ya.
Any changes to the AR Tool landscape since this video was made? For example, Flutter , ARLoopa, or Flet/ARCore ?
I'd like to make an Android application that can find components from a circuit board! Just use your camera and it will overlay a marker on the component... however, not sure if there is a minimum marker size , and if it can be overlayed with such high precision.
For example, if you have a sheet of paper with a grid of squares, say 50x50.. if A4 is said/entered, could AR use a fiducial on the paper to calculate how far into the grid it needs to place a marker (scaling it based on the the angle and how close the camera is to the sheet).
Helped A Lot! Thanks!
