hi! when i make the image target as the child of ARCamera, the image does not appear even though the database and image is selected. Help!!

[@marckeene4524]

You have to find your target image and change the texture type. Assets>Editor>QCAR>ImageTargetTexture>Your database name Select the target image, change texture type to sprite and click apply.

[@desecratorwow517]

Thank you!!!

[@linnanwang8935]

Thanks a lot!!

[@marcusnash8238]

a thanks alot for that explanation

Great tutorial. Now, I know how to add a virtual button to my AR image. I will complete another tutorial tomorrow. My kind of teacher, you just get the job done.

[@panagiotis3183]

You helped me build my first augmented reality app..Thanks for the experience bro!

[@jasonhansen8340]

Hey thanks for posting this I'm working on a project that has virtual button but I couldn't figure out how to add the script. Thx. Very easy to follow your directions.

[@MatthewHallberg]

No problem, but yeah it wasn't the easiest thing to figure out. I found some example code that had like 20 unnecessary lines which got me even more confused.

[@Ucinoz]

"Missing reference exception: The object of type 'Object' has been destroyed but you are still trying to access it." i've got this error when i try to play it.and so far your channel have been a blast automatic subscribe for me.

[@MatthewHallberg]

There should be no type Object it should be GameObject, maybe that's it, not sure though.

[@justinmisajon]

Here's how you make the virtual button with the latest vuforia. Click image target -> image target behaviour (inspector) -> advanced -> add virtual button

[@gladiumcaeli]

Hello developers, if you are having problem following the tutorial because of the AR camera is different. You can get all of the settings he had change in ::Vuforia behaviour script >> Open vuforia configuration >> Datasets and enable both those check boxes

[@paipai_yy]

I really love your amazing tutorials!! Could make more?! Cause there are so limited tutorials with AR in the KZbin.... Please!!

[@MatthewHallberg]

Yeah absolutely, anything in particular you want to learn. I was thinking the next one would be on markerless AR with Kudan.

[@paipai_yy]

Have you tried something with leap motion to create a more interactive application? I am working on that, and I think that would be pretty fun! Also, looking forward to your Kudan tutorial!

[@paipai_yy]

Besides, could you make a tutorial related with vuforia TexRecognition?

[@MatthewHallberg]

Such a good idea I forgot about that!

[@MatthewHallberg]

Jiahe Chen I am broke or else I would buy that and try it. I don't know much about it though your gonna have to teach me lol.

[@Rubafix989]

Thanks a bunch ! Clear and concise

[@MatthewHallberg]

Glad to help!

[@WhiteArtsMagic]

With AR can you put your asset into any scene or does it need the base image, in your case the magazine, to render the object to the view? How would you handle this for others that might download your AR app that dont have the same base as you?

[@micahshanetaylor5562]

I am trying to replicate this with Unity 17.2 in which Vuforia was integrated. However, I cant find the Virtual Button. Does anyone know where the Virtual Button is located in the Unity 17.2 Interface?

[@user-bb4rn6xm9w]

Thank you! I can use vuforia's virtual button, basic! if i don't now about using vuforia. i will visit one(even more)more time

[@0TheImaginary0]

Thank you very much for the tutorial is very helpful, I am starting researching in augmented reality for my Ph.D. and seeing a verity of the tools in your channel is a great source for me and easier to follow .. I might ask you in the near future about AR specific detials.

[@nikadevashvili5006]

i like it, waiting for next video episodes

[@sgambolati]

Thanks for clarifying some things to me. Very usefull video!

[@MatthewHallberg]

+Sebastian Gambolati thanks!

[@adelinethokmay2029]

Thank you very much for sharing this with us! Although I'm still trying to make it work. Will send results soon.

[@MatthewHallberg]

Anytime! What kind of issue are you having though?

[@cassfo]

Maybe include a joystick to control characters objects and interact with the enviroment? A bigger target can create other objects to plataform/colide/things like this.

[@MatthewHallberg]

By joystick do you mean a homemade one (maybe an Arduino that communicates via bluetooth to the phone) or do you mean a virtual joystick? Also, on the note of colliding with other objects Vuforia has a "smart terrain" option where you can basically add colliders to random objects on your table with computer vision, so maybe I will do that soon because I have always wanted to try.

[@cassfo]

I was thinking about setup a xbox controller, but the ideia of virtual joystick with buttons on the screen (and not in the target) is a great ideia. And yes, smart terrain is the point. Vuforia is new for me and i didn't explore too much the 3d targets. A nice tutorial like yours, maybe in two videos, teaching the controller and the smart terain, I'm sure your audience would like

[@001zeal]

I get this error : vbScript' does not implement interface member `Vuforia.IVirtualButtonEventHandler.OnButtonReleased(Vuforia.VirtualButtonAbstractBehaviour) I have using Vuforia in the script. How do I solve this ?

[@MatthewHallberg]

That error message means you are missing the OnButtonReleased() function. You have to implement all the functions from the video and they are case sensitive.

[@luisarmandohernandezdoming275]

Thanks, I made it with a spider model and looks so cool.

[@pauldanielmagdangal5052]

why not combining virtual button and markerless augmented reality? its a big help 😁 trying to study more about this for our thesis next semester

[@yaarauetta]

That was very useful. Thanks!

[@MatthewHallberg]

anytime, thanks for watching.

[@ayomidefagbohungbe9773]

Awesome tutorial... Well done!

[@Jono6321_true]

I couldn't figure out why my button wasn't working. After going through the script and checking every letter, it turns out that right at the bottom, there's a + symbol -_-. Great video by the way

[@MatthewHallberg]

Awsome, glad its working for you!

[@minz0]

Hi! Love these videos you have. can you do a tutorial on how to create a piano you can play with AR?

[@amirkahinpour547]

You're a hero man, love your channel. A big, hugee thumbs up

[@christianVSR]

Thanks for making this tutorial. This is so awesome!

[@salar_techno1164]

[@danielggonzalez5785]

wouldn't this classify as MR? Great work, even though somet weaking is needed for newer releases.

[@vikranthkanumuru8900]

Hello, thank you for the wonderful tutorial but I keep getting this error, error CS0246: The type or namespace name `VirtualButtonAbstractBehaviour' could not be found. Are you missing an assembly reference? I would very much appreciate your help

[@artembukovetskyy7724]

Have you find a solution for this problem?

[@filipeferreira7818]

Hi! Great Tutorial I would like of do this project with a bottle real (plastic bottle) and simulate the water level. Could you tell me what resources I need to know/learn or what I need search in web to study and learn more to do this. Other question, how resize objects in unity with real objects?

[@techbox1467]

hi, great video tutorial. I am a week old with AR. How can I make two image targets interactive with other.

[@derzuomaia]

Great tutorial, is it possible to make the hand appear over the button and not the button above the hand?

[@nickromanek9444]

Awesome video! I just did this yesterday and the process is more or less the same. After 6 years you think the process would be a lot simpler, any other tools out there that have improved on this process? Thanks.

[@pmuruaga]

Hello Matthew, nice tutorials! I leave an idea for some future tuto, is there a way to update an app, or get new image target with video/models/etcetc. dinamically during the time. Thanks!

[@MatthewHallberg]

not sure what you mean, elaborate maybe?

[@pmuruaga]

for example a printed magazine, on each edition the targets will be different, on one edition I would include some ads and with the app the user will see a video, and on the next edition with the same app I would like the user to watch another video or a model maybe.

[@NabilMajid]

I did an app, that open the vuforia camera then recognize the image target from the owner of the restaurant and realese a cupon, inside the apo, but is not anti fraude, because the people can screen recorder the image target when it doing the recognition, an later he can print the image target an release more cupons, how can i prevent that from happend?

[@sarabruszt6113]

Hey , really great video. thanks for doing it . I just have a kind of dumb question. Where did you download the vuforia from exactly ? Or what is it exactly ? I was looking at stuff in the asset store in unity and on the website and I am just not clear on what package to get exactly. Can you help me out ?

[@siddharthagrawal4280]

hey matthew, how do i know prefab has animation. The current version of unity appears quite different from the one in your video could you please help me out here, just a beginner

[@sukhnakh]

Hi, On Button Pressed i want to read .xls data and display it. For example. display Diameter = 200 (read from xml) and then i want to edit this value. and save back in same .xls. Is this possible?

[@carlosferegrino290]

Hey Matthew make a tutorial but using the ARWT without using vuforia. This library permiss to make ar apps for web-base app

[@qAntBcn]

thank you for sharing a knowledge =)

[@MatthewHallberg]

No problem, thanks for watching!

[@MsHlecter]

Hi! could you tell me how you fix object shaking?

[@hasnulafiqah5825]

Hi, can i ask you. where can i get the virtual button? because in your tutorial you seem like you already have virtual button in folder vuforia prehabs. Im stuck over there. Help please! Urgent.

[@pavankumar693]

hi mathewi love ur type of teaching and i just want to know hw can we use multiple targetsfor the multiple animations palying when we click virtual button

[@MatthewHallberg]

Yeah you should be able to use multiple image target prefabs and then in the inspector for the ARCamera I think you can change the number of simultaneous targets (I believe it is at the bottom?). Just a word of warning though tracking two or more targets at the same doesn't work all that consistently from my experience with it.

[@pavankumar693]

thnksss

[@marykita8645]

Hi Matthew, Thank for your video. Sorry for my bad english, i'm french. I follow step by step, but when i play with the webcam, the zombie walk automaticaly and the button seems doesn't work while i desactivate play automatically in animation zombie. Thank for your help,

[@pyuusein]

Hi Sir, Thank you so much for your tutorial. The tutorial fit exactly for my purpose at presentation with AR. and tried to followed tutorial step by step, i stuck at below Console error. Assets/vbScript.cs(5,14): error CS0738: `vbScript' does not implement interface member `Vuforia.IVirtualButtonEventHandler.OnButtonReleased(Vuforia.VirtualButtonAbstractBehaviour)' and the best implementing candidate `vbScript.OnButtonPressed(Vuforia.VirtualButtonAbstractBehaviour)' return type `void' does not match interface member return type `void'

[@abdude100]

sir i need to know about how to apply this zombie on the image target by touching on the mobile screen

[@MatthewHallberg]

Watch my latest video that should help with your issue!

[@bjugdbjk]

super cool, great work... I have a question here,Instead of animation , Is there way I can project some text on the target object..? Ur help will be highly appreciated.

[@ManikandanM-gi4id]

I've a problem when build the android apk (CommandInvokationFailure: Unable to convert classes into dex format.)Any one please help me

[@saltguey8516]

This all cool and dandy but how do you actually package the whole thing and make it usable, from a cell phone camera or an app or something. How do you go from building it to a finished product?

[@MatthewHallberg]

+DaReal Hons just go to file build settings and change the build platform to android or iOS. Click build and run with your phone plugged in and it should load right up.

[@saltguey8516]

thanks for the reply, this is probably WAY over my head right now. I have no experience with swift or objective-c. I ran the build with Xcode and It came back with like 300 suggestions and warnings. It managed to load to my phone after 15 min and it accessed my camera but it was just a black screen. LOL

[@aryasaktidraw]

Great tutorial! but how do you show and hide that sign "Zombie Walk" in the beginning? thanks

[@vanorley20]

Hello, good video, I have a problem, I am developing an AR app with Vuforia that consists of a 3D model to learn human anatomy, with the touch I can rotate, scale, move and select each part of the body and it shows me a label, I also have buttons; ** that when the 3D model is in the same direction as a Canvas button, pressing it also selects the 3D Model ** How can I make sure that the Model is not selected when I press a button?

[@muhammadsameer883]

Good Job Matthew

[@sahilgarg2989]

IVirtualButtonEventHandler has been depreciated from vuforia 9.1 and now i have to use RegisterOnButtonPressed() instead of RegisterEventHandler() but i don't know how to implement this method RegisterOnButtonPressed(). The only thing i know is that a "UnityAction" will be passed as an argument to RegisterOnButtonPressed() but i don't know how to make function call whenever a virtual button is pressed. I'm totally confused about all these things. So i request you to please suggest something or you can provide a piece of code because it will be more clear to me. Thank You :)

[@21design_eu]

I just can't see the picture when I press upload / it gets uploaded but no image in the image target. Why is that ? tried 2 times on vuforia site and still no image loading after I insert the images/ also not recognizing the printed image

[@abhinayar2027]

Hi, i've done everything you said. Eventhough i'm not able to drag and drop, i imported the asset. It didn't work :( i've tried with different image targets too. The plane doesn't show up at all!

[@hosseinyousefi3816]

very nice, thank you

[@MatthewHallberg]

anytime!

[@SunithaS05]

Hello, I need a help. In most of these tutorial the 3d object is preloaded in the scene while building it. I want to build an app in which the 3D object is loaded on to the camera only after we select it from a list or something. please please help.

[@chengjieli3592]

Hello, I have a A4 size poster, which has Title, Diagram and Text section, on each section I add up a virtual button and zombie, so what I want to realize is when I point at each section, the corresponding zombie will perform "walk" animation. However, only the one that is in charge of Text section worked well. Other buttons didnt work. I also try to only use one button, but enlarge the button to the size of almost covering the A4 poster, in this case, this button didnt work as well. So the question relates to multiple buttons registration and the influence of the size of the button? Do you have any idea how to solve it?

[@helloworld3003]

Hi I really like your tutorials they're awesome ,, can you please film a tutorial on how to create an AR app (for android) that will have like some objects stored in a db like a catalog and we kinda choose for example the sofa and we have that sofa in our physical environment ,, Like show us the step by step and how can we store these objects(models) into a mongo database and link them to our project ? Thanks in advance :)

hey man liked your video!! I am facing a problem like if I want to create a team of zombies but its not recognizing multiple times even when I put the same picture twice or thrice..Any suggestions

[@AnkitKumar-mz2sl]

Hi..Matthew I'm great admirer of your work and I follow your videos they're great n easy to learn. Recently I've been working on adding virtual button on my AR app and I want to display some texts n sound cliPs on button Pressed..so could you helP me out with these..what else changes should I've to make in my vbscript..to get that desired results...??

[@amanyddv]

I am getting a error ( virtual button can not be created INVALID_AREA) while creating virtual button, can you please tell me what should I do to solve this error .

[@uurossss]

I miss some settings on Inspector: like Database Load Behavior and others And when i charge the ImageTarget, on the screen it appears only a white rectangle

[@MatthewHallberg]

Check the top comment, on my other augmented reality video where we make a maze. I think there is different versions between 32 bit and 64 bit so the interface is a little different. Hopefully that helps.

[@osamaelawad1428]

[@sang-gwiyoon4943]

Hi. Thank you for useful video. But I have a problem about virtual button. I follow your video procedure and checking the all letter of scripts, but the debug message do not working... I use 6.2 version vuforia. Is there anything deference with your version?

[@oscaralcaraz2849]

Hi, i have one question, im new in unity, i have a 3D object (a person) and i want to make some parts of the body clickable (touch) but the problem is that if i make like buttons static when the body is zoom in/out or rotated the buttons are gonna stay in the same position

[@rafiullahwaseem7209]

i am using unity2017.2.0f3. when i imported the vuforia package, it shows an error message "the associated script can't be loaded, plz fix any compile errors or assign a valid script". when i open that script in mono develop and build it , the error pops up "Error CS1617: Invalid option '4' for /langversion; must be ISO-1, ISO-2 or Default (CS1617) (Assembly-CSharp-Editor)" .plz help

[@weiruan7719]

Hi,thanks for your helpful video. I was trying to follow you step by step, but finally the button doesn't work which was really annoying. I used VS 2015 to programme the script and I cannot figure out what was wrong with that. I didn't see "button down!!!" in console section. Help!

[@MatthewHallberg]

Hmm, are you getting any errors in the console, is your button covering a feature-rich portion of your image?

[@weiruan7719]

MatthewHallberg Thanks sooooooo much. My button didn't cover the imager target. Thank you!!!!!!!

[@weiruan7719]

MatthewHallberg Hey sir, but I cannot figure out another problem, which is when I use build settings no matter on PC or Android, what I got were all black scenes. Can u help me?

[@omkarpatil2854]

hey i am facing same problem did you get the solution? please help!!!

Can you solve this problem? I'm recieving Type or namespace 'IUnzipper' could not be found (are you using a missing directive or assembly reference?)

[@larsa4209]

Hi dude thank you very much for ur amazing videos. I've a small question, when i try to use my camera with the play button like ur doing at 4:46, i only have a black screen with "Display 1, No cameras rendering". Can you help me ?

[@abhijeetgarge4861]

So my button doesn't help to animate..I could see the debug logs perfectly when I press and release the button. But the object doesn't move. Any idea what could be the issue?

[@abhijeetgarge4861]

Okay, I figured out the error. When I checked the console logs after creating a whole new project again, I found out this error: 'Default clip could not be found in attached animations list' (which surprisingly wasn't a part of the earlier project)..anyway... So the problem was with the 'animation'(The action that you have assigned to animation) of the Gameobject > Rig > Generation.... "store in root ( deprecated)" instead of "store in root(new)"...Try this out for those of you stuck like me! HTH!

[@pamcas4502]

instead of adding zombies, could you make a video start playing when the app scans the magazine?

[@parkerplatt7201]

Is there a way to get rid of the, "Vuforia" watermark on the bottom left - hand side of the monitor / camera? Just a curious thought.

[@MatthewHallberg]

Yeah to get rid of it you have to pay $500 per app you want to deploy as far as I know. I havn't tried to disable it otherwise.

[@WaffleBladeFilms]

Hey, your videos are awesome man. There isn't a whole lot of helpful material out there, so these videos are greatly appreciated. I'm trying to cue a scene change on the vbutton click, but the vbutton doesn't seem to be working. If I try to use my finger to touch the vbutton, it does nothing, but if I bring my camera closer to the base image, it registers as a button click and changes scenes. Not sure what's going on, have any thoughts?

[@MatthewHallberg]

+Chris Repka those buttons can be finicky, I would make sure the part you defined as a button is actually over some feature points on the image, you can see those feature points when you click on the image in the vuforia developer portal.

[@WaffleBladeFilms]

I actually just solved the problem thanks to one of your earlier comments. I look forward to seeing more videos, hope you keep going with them. Thanks again for the help!

[@JayPatel-kb1sc]

How to make my finger shown on the surface when we press the button? So that it looks like real..

[@scargomez9437]

In what language you script in Unity? And how can I insert a video instead of a zombie?

[@sketchpadmedia]

Hello, I got stuck where I bring in the image target, it is a child of the AR Camera but the image of the target doesnt show up as I follow the same procedure as the video. I also tried to import the texture I was using and assign it (drag and drop on the image target). Neither worked when I hold up my printed target to the camera. My plane is a child of the image target also. Any ideas?

[@MatthewHallberg]

It seems a lot of people are having this issue and I am not sure if it is a change in the new Vuforia or what. Give me like a week and I am going to do a quick tutorial on how to get stuff working in the new Vuforia.

[@tiantianzhou2670]

Thank you for the tutorial, but I have the same problem with the image target...

[@jonalbertson5241]

FWIW same problem here. I found a digital copy a magazine that was laying around in my office, and the grass texture doesn't want to play nice. It appears for a split second when the plane is not a child of the ImageTarget, and not at all when the two are parented.

[@mashaosorio8656]

Hi Matthew! I am learning how to use Unity and I want to know how can I make an AR black dot that expands into a large black hole in the wall? how hard is this? and how can I export it into being used through the camera of an iPhone :)

[@MatthewHallberg]

So you can definitely build it to an iphone no problem just download xCode. As far as the dot though you may want to use markerless AR so you don't need to rely on an image to augment from. You can do this with the Kudan plugin from unity. I have not used it yet but it's definitely on my list of videos to make.

[@mashaosorio8656]

Thank you so much!! and look forward to the tutorial :) !

[@andremachado6751]

Hi. Very Good video, I like a lot. One question? How can I do menu's with Augmented Reality in Unity using Vuforia,for example? Can you do a video related with that? Continue with these videos. Good Luck ;D

[@MatthewHallberg]

You can do it with these buttons, just repeat the process for however many you need. You could also add a canvas to the hierarchy and use Unity's built in UI components to make an on screen menu as well (non-AR)

[@andremachado6751]

Ok thanks WireBeings ;D

[@surenderthyagarajan4770]

Hey!! Amazing tutorial i've build the project completely except the part that when i release the button it doesnt stop animation.I'd also tried to test it by using the debug statement but no logs found on the console. Please respond me ASAP

[@ajluanzon]

Would be great if you make a simple tutorial on how you do a text popup when you pressed that button! Sorry, really a noobie in unity!

[@Kamalprasathbalaji]

is there any way to do augment reality of a model with live motion capturing. So that 3d model mimics our action from behind the camera in video

[@MatthewHallberg]

Yeah I have no experience with it but you need the kinect for that in order to track a human body and its position. I am going to try to get one soon and to some experimenting with it so I will keep you posted.

[@Kamalprasathbalaji]

+MatthewHallberg thanks for the reply friend, i have kinect. how should i do it?

[@gamemakerdude]

Excellent tutorial! Does anyone know if this is possible with a different (free or cheap) SDK? I wanted to develop apps that use virtual buttons like this and distribute on the Google Play store. Or can I do that with Vuforia's free license?

[@dotan19586]

Hi, I also having the same problem like 'rahul manoharan', and any attempt to fix the problem don't work.The log file said Trackable *image* lost. And the plane shown in the middle of the camera screen without disappearing. Hope you can help, thanks.

[@MatthewHallberg]

Sorry I might have forgot this in the video, click on ARCamera and change world center mode to device tracking. That should do it. Let me know.

[@dotan19586]

Still no, I changed the world center as you suggested, ans still the plane shown in the middle of the screen (when i press play), and tracking lost. In "web camera behavior" script there is "no webcam profile has been found to "usb camera". I'm using my laptop camera. and in the "camera device" option there is only "USB camera" and no other option. I hope there is another way to fix this frustrating problem. Many thanks!!

[@dotan19586]

OMG! the problem gone! now it's working good. But still one last question, it's seems that the tracker lost the image very fast, and if i move the picture a little fast the tracker lost again. How can i improve the stability? it's related to the camera quality or picture? maybe something with the ARcamera? Thanks again :)

[@MatthewHallberg]

Awesome, glad its working. As far as the tracking it does lose it when moved quickly so no ideas there. You could turn on extended tracking on the ARCamera which will help it stay tracked when out of frame, but thats all I could suggest. Hope that helps. Let me know.
