[@CubicBrain]

Thanks a lot!

[@dariosimunovic4938]

Quick and down to the point. Amazing !

[@CubicBrain]

Thanks a lot!

[@kpk1171]

[@tianhaowang5012]

Thank you so much for the tutorial!!!!!!

[@muhammadsameer883]

Thanks Bro completed this one

[@TheDeadlyJedly]

Missing the player settings just adds confusion , So thankyou for covering the process top to bottom!

[@CubicBrain]

Thanks, Yeah, my thought exactly. Its important to know all the setup basics before going further with Vuforia AR development

[@AJ-VITHEE]

Excellent Tutorial, I am a novice on this track. I love it. But i have some question, when i try to press a play button in unity, it always show me an orange display only...how i can fix the problem. Thanks !!!

[@jacksonabernathy1683]

Best tutorial out there

[@ArtinTime]

Thanks a lot for all the training, certainly extremely helpful. I have a question if you have the time regarding the issue that I am having when triggering the animation when the target is found. I can’t seem to achieve the result I need, it always plays automatically. I have found scripts that can solve the issue with video clip and it’s working, however the problem I have is with the timeline animation. Is there a way to trigger the timeline animation when the target is found and stop when the target is lost? Thank you so much

[@CubicBrain]

Hi, thanks. You should be able to use the tracking found and lost functions ex: private void OnTrackingLost() { anim.Stop();}

[@ArtinTime]

@@CubicBrain Thanks a lot for direction. I tried but it gave me an error: The name 'anim' does not exist in the current context [VuforiaScripts] Maybe Unity 2018 doesn't support "anim" in the Default trackable handler script? Sorry i am adding long script here but this is what my script looks like at the moment: using UnityEngine; using Vuforia; /// /// A custom handler that implements the ITrackableEventHandler interface. /// public class DefaultTrackableEventHandler : MonoBehaviour, ITrackableEventHandler { #region PRIVATE_MEMBER_VARIABLES protected TrackableBehaviour mTrackableBehaviour; #endregion // PRIVATE_MEMBER_VARIABLES #region UNTIY_MONOBEHAVIOUR_METHODS protected virtual void Start() { mTrackableBehaviour = GetComponent(); if (mTrackableBehaviour) mTrackableBehaviour.RegisterTrackableEventHandler(this); } #endregion // UNTIY_MONOBEHAVIOUR_METHODS #region PUBLIC_METHODS /// /// Implementation of the ITrackableEventHandler function called when the /// tracking state changes. /// public void OnTrackableStateChanged( TrackableBehaviour.Status previousStatus, TrackableBehaviour.Status newStatus) { if ( newStatus == TrackableBehaviour.Status.DETECTED || newStatus == TrackableBehaviour.Status.TRACKED || newStatus == TrackableBehaviour.Status.EXTENDED_TRACKED ) { OnTrackingFound(); AudioSource audio = GetComponent (); audio.Play (); } else { OnTrackingLost(); AudioSource audio = GetComponent (); audio.Stop (); } } #endregion // PUBLIC_METHODS #region PRIVATE_METHODS protected virtual void OnTrackingFound() { var rendererComponents = GetComponentsInChildren(true); var colliderComponents = GetComponentsInChildren(true); var canvasComponents = GetComponentsInChildren(true); var animationComponents = GetComponentsInChildren(true); // Enable rendering: foreach (var component in rendererComponents) component.enabled = true; // Enable colliders: foreach (var component in colliderComponents) component.enabled = true; // Enable canvas': foreach (var component in canvasComponents) component.enabled = true; // Enable animation': foreach (var component in animationComponents) component.enabled = true; } protected virtual void OnTrackingLost() { var rendererComponents = GetComponentsInChildren(false); var colliderComponents = GetComponentsInChildren(false); var canvasComponents = GetComponentsInChildren(false); var animationComponents = GetComponentsInChildren(false); // Disable rendering: foreach (var component in rendererComponents) component.enabled = false; // Disable colliders: foreach (var component in colliderComponents) component.enabled = false; // Disable canvas': foreach (var component in canvasComponents) component.enabled = false; // Enable animation': foreach (var component in animationComponents) component.enabled = false; } #endregion // PRIVATE_METHODS } Thank you again, if you have the time to have a look at. really appreciate it.

Can someone please clarify a few things for m please? Do you need Unity to use Vurforia? I see that you canbuy Vuforia and they offer a few different options. Can you create AR content with Vuforia as a stand alone or do you need to purchase both Unity and Vuforia?

[@coromel]

You'll need both those programs indeed. Fortunately they are both free. When installing Unity there will be an option to include Vuforia.

[@srita.garabatos7761]

Thank you for this tutorial

[@fabiotgarcia2]

Hello CubicBrain! Can you please show us how can we make a camera focus works in Vuforia 6.5.22?

[@brunoomardorivalgutierrez1141]

Could you do a Vuforia Persistent Extended Tracking please

[@abhishekarya9]

Thanks for the Tuts. Its my 1st tuts on AR. Can you please tell how to make video playback AR app in Unity 2017.2. Please

[@CubicBrain]

Hi, you have to add the a video to your scene, and a video component to your script, and then your should be able to write a play function for your script. Inside of either a keypress function or a virtual button functions, add this: var videoPlayer = GetComponent(); videoPlayer.Play();

[@276matto]

You are a hero

[@حمزة-ب7ش]

Is it possible to disable the z axis!? I just need to move an object in y-x without changing in rotation and scale. Can we do that?!

[@alainjouni]

I’m stuck on the part where you click play and your camera feed appears, having trouble getting my camera feed to appear

[@CubicBrain]

Not all cameras are compatible, but you can check the Vuforia settings if the camera is registered.

[@alainjouni]

CubicBrain thank you for the reply! After some more tinkering I found it was in fact the camera so I’ll be trying another one soon

[@ammaramr2838]

Sir why my unity doesnt have vuforia?,how to download it?,it doesnt have in vuforia website

[@CubicBrain]

When you install unity, you can choose vuforia as one of the components.

[@hanimbuzz]

why i cant add vuforia in unity ? there is no vuforia when i right click on the hierarchy tabs

[@CubicBrain]

Hi Mira, Vuforia needs to be installed as a package when you install the newest version of unity. (just link when you add iOS or Android support)

[@hanimbuzz]

when i press play, why does it says "all compilers error have to be fixed before you can enter playmode" ?

[@CubicBrain]

this means that you have an error in your code. you have to check for syntax errors.

[@no101vmv]

When i start app on android device, i see only a black screen until I hit the marker. Some one know answer?

[@CubicBrain]

Hi, try to go to the Android settings (player) and turn "Auto Graphics API" off. this might cause it to go black. If you turn this off and only leave OpenGLES2 on, the problem might get solved.

[@no101vmv]

Thx, but i think is a Vuforia problem)) This problem has on one scene, in editor or on mobile) Because in new scene all work ok)))) And Vuforia have other error. Sometimes vuforia say InitializationError. InitError can be solved only if restart Unity.

[@TheSkyGamez]

i had to reinstall unity to get the vuforia thing in it :(

[@CubicBrain]

Hi, yes, you have to select the vuforia package in the unity installation menu.

[@youshaarif4253]

followed all steps, but the cube is not showing up :/

[@CubicBrain]

Hi Yousha, Have you activated the image and database for the target. if it's not activated, then it wont know when to show your cube.

[@youshaarif4253]

CubicBrain In my case i forgot to put license key in unity.

[@bennmorgan]

is it ted mosby speaking?

[@CubicBrain]

haha, no, but I'll take it as a compliment!
