thank for your video. how can i touch to prefab, then show information ?

[@DineshPunni]

Instead of moving the object when touching you can invoke an Unity event that (for example) opens up a UI with Information

[@MitchTheMarine]

Loving these thank you! I'm not sure if it shifts, but when you're teaching code, if you could try and keep it as centered as possible on the screen it'd really help, other than that thank you!!

Thanks for the feedback Blalien. What exactly do you mean by that tough?

[@MitchTheMarine]

@@DineshPunni Sometimes when you're working on sections of code you're at the very bottom of the screen to the point the timeline of the video can block it out. Just puts a barrier up every now and then, not a huge deal, it'd just be more accessible screen center.

[@DineshPunni]

Good question, I'm teaching this in my AR Foundation course. You can set the transform.forward of your object to the plane.normal and then it should be fitting well.

[@trumanboone5395]

Great video! Have you done anything with two finger rotation or scaling of objects?

[@DineshPunni]

Thanks for the feedback :) Yes, however, that works independent of AR Founation. There are lots of great (and free) tools for touch input in the Unity Assetstore. I may do a video in the future about that.

[@jonasharrison6355]

Hey any advice on what to do if I want to be able to place an object in the environment ONLY AFTER I have pressed a button on screen? Currently working on something that uses this as the code to place an object in the environment, but right now my screen turns green after I select the button.

[@e3di1]

Amazing tutorial, thanks so much. I have a quick question if you don't mind please. How would I stop the cube position being effected when someone clicks on a UI icon please? Thanks :-)

[@DineshPunni]

Thank you :) Best would be to invoke an event that disables the movement of the cube in the else clause (Line 54). There are (as always) a lot of ways to achive this but one simple solution is to have another if clause in there that checks if the button has been clicked. Something like: ... else { if(!buttonClicked) { spawnedObject.transform.position = hitpose.position; } }

[@e3di1]

@@DineshPunni Wow thanks for that!! I really appreciate it. I seem to get an error saying 'The name 'buttonClicked) does not exist in the current context' .

[@DineshPunni]

@@e3di1 Because that was only a small example, how it could be done. If you want it to work this way you'll have to define a public bool variable called buttonClicked, which get's set to true when actually clicking on the UI. I'd recommend to check out Unity's UI tutorial if you haven't worked with it before.

[@DineshPunni]

Hey Gayle, thanks for the feedback. It's quite hard to do remote debugging without knowing much about the project. It could be a tiny mistake but hard to see.

[@moritzjantzen8612]

how can i change betwen 2 object on a buttonclick

[@iziaulla]

Hi Dinesh, had a few questions regarding this video that I hope you would shed some light on for me. First thing, I liked how you were able to move the instantiated cube without having to go through the TouchPhases (TouchPhase.Begin, TouchPhase.Moved, ...). So you don't really need them correct? Second question that I had was the actual instantiation of the cube. I'm not sure if you've used Google ARCore or not to do AR stuff, but in Google ArCore I was able to instantiate an object if the plane was vertical, horizontal, or both. Can you do the same with AR Foundation?

[@DineshPunni]

Heyhey sure, 1. In the video, the cube (or any instantiated object) is following the image that is beeing tracked. I was basically moving the image on my screen and the cube followed. If you want to move the objects though touch input on your device you'll need a different approach. 2. As far as I know, AR Foundation has vertical and horizontal plane detection as well. Especially with Unity's MARS tools it should be possible. A lot of time has passed since recording the video, so I'm quite sure it should be working :)

[@emersonbrinks7200]

is there a reason that you make a private vector2 touchposition at the start of of the script when you keep adding new local vector2 touchpositions and using those?

[@SethSScott-li6vr]

yes, i am seeing errors even in the video with the underlines.....also, mine is nott registering the raycasts it seems

Thank you so much!

[@DineshPunni]

Glad it helped! :)

[@professorm4171]

If you have a model more complicated than a cube (with textures, etc) , you'll run into memory issues that'll cause temporary freezing. You need to use Addressables.InstantiateAsync() for better performance.

[@DineshPunni]

But that does not happen with only one instantiated object right? It also worked for multiple mid-high poly objects so far. But you're right, using Addressables it better for performance. I might do a video on that topic in the future. Thank's for your comment

[@professorm4171]

@@DineshPunni I think it's the model texture has a lot to do with it. Adding a texture in memory during runtime could slow things down. But I do instantiate multiple models at runtime and see the bad performance.

[@DineshPunni]

@@professorm4171 hmm interesting. It could be that your phone is the bottle neck there. Usually you don't have performance issues so fast, unless you have extreme high poly count and high resolution textures.

Hey there, for some reason KZbin decided to put this comment under spam so I didn't see it right away 🙄 If you got you right you want to spawn the temple model instead of the cube. So basically you have to create a prefab of the temple model and put it in the GameObject to instantiate field.

I am a beginner, so there will be a better way of doing it, but you can try to have a list of prefabs and put into a variable your click count. Use the variable to spawn objects from the list by their index number.

This is almost the same code from Dilmer Valecillos from a tutorial 1 year before. This script just allows one prefab in the scene.

[@DineshPunni]

Well, simple code is the same all over the world ;) It's most likely gonne be similar to Unity's and whoever elses video

Why touchPosition = default?

[@northisdead1999]

My object starts shaking like crazy when I go close to it. Does anybody know why?

[@DineshPunni]

Could be due to the tracking. It's generally helpful, if you scan your environment a bit before you start doing fancy things ;) What phone did you use?

hi, thanks for your tutorial. I am using Unity.2019.3.0f6. I installed ARFoundation 2.1.4 and ARCore XR Plugin 2.1.2 from Package Manager. But when I go into the C# script. UnityEngine.XR shows that it only has Provider and WSA namespace. I cannot see ARFoundation. What am I doing wrong?

[@sukalpomitra]

HI IMERSITY, found that its an issue of Omnisharp extension of Visual Studio Code. I am using Visual Studio and its working fine. Whats the Visual Studio Code version that you are using? I am in Mac 10.15.3

[@DineshPunni]

Glad you found it on your own :) I‘m using the 2019 version of Visual Studio

[@DarkHeliosGamesInteractive]

Also today I have 3 critical errors..... : (

[@DineshPunni]

Can you tell us about the errors? Also, what Unity + AR Foundation version are you using and what device? Maybe we can find out together

[@DarkHeliosGamesInteractive]

IMERSITY Unity 2019.2.17f1 I have to reproduce it again since I deleted the script but I remember that I hade an missing assemble error about pose and another one about hits I really don’t remember the third one

[@DarkHeliosGamesInteractive]

IMERSITY AR 3.1.0

[@DineshPunni]

hmm okay, missing assemble error about the pose script could mean that there was something wrong when importing the ARFoundation Subsystem packages in the main package.

Hi I have a problem I updated my unity and AR Foundation and XR Toolkit to 4.and when I drag the ARTap to place code , it attaches the AR Raycastmanager that needs RayCast Prefab and this is not in video and I think it is because of update.what should I do?

[@DineshPunni]

Unity releases updates every few months and sometimes they deprecate/add few methods/components. So, you will have to look at their documentation for the version that you are using and make the necessary changes.
