AR Object Selection with Raycasting in AR Foundation with Unity3d

AR Foundation with Unity3d is used to create an augmented reality scene where I walk you through the implementation and all the components required to use AR to perform object selection and also clearing out selection on not selected objects. We also go through the code and I explain to you how everything is configured and how the source code works.
New AR Foundation Components used in this Scene:
- AR Object Selection
- AR Clearning out selection of not selected objects
- AR Floating Objects

Thank you so much for this, really appreciate it!! Is there any way to make an audio clip start when an object is selected?

Great video!

So when do I have to use the raycastmanager ?

[@bilbostabbins1882]

Thank you so much Dilmer Valecillos for this tutorial I was very confused when it came to raycasting with either the AR Raycast Manager or Physics Raycast and this video help clear it all up! Although I'd like an explanation as to why we use Physics.Raycast instead of the AR Raycast manager Anyway thank you for the tutorial! Liked and Subbed!

[@bilbostabbins1882]

nvm I found the answer in one of your other videos! I Hope you are keeping well Dilmer!

Hey Im using this for an Ar School Procjet. Im new to Unity how do i fix "The type or namespace name' PlacementObject' could not be found( are you missin a using directive or an assembly reference?)

[@yensid46]

Trying to follow along and build this as you explained things. Is there another tutorial that goes into detail? because this one is pretty much high level and seems to be missing things. Like the canvas, dismiss button, If I were experienced at this I wouldn't need to be watching these tutorials. The playlist does not seem to be in order for following along.

[@andyward7961]

Hi Dilmer, thanks for the tutorial. I have followed this tutorial and the next one about selecting multiple objects. I am experiencing an error when instantiating multiple objects. As soon as i start my application, many objects are spawned as i look around with my phone even without pressing on the screen. I have tried to change a few things and have followed and double checked what you have included in your script however there is still an error. Thanks.

[@dilaysapmaz2572]

Hi Dilmer. First, thank you for the video! May I ask that what this button does? in AR Session Origin -Dismiss Button?

[@amalderraz5942]

Hello @Dilmer Valecillos, thank you for videos, it's too helpful and beneficial. I have the issue with the gameobject. My gameObject is a prefab with children that should be instantiate it after detectecting an indicator. I don't know how to deal with it. Need some extra-information.

[@jpreskitt]

Hi Dilmer ! Love your channel. Do you have the project files for this? Thanks in advance.

[@bestseller1234]

Great work Dilmer.... really helpful. Have you tried using the AR Camera to trigger an event -- activate a gameObject or trigger animation for a gameObject. When the player/ Camera moves within a certain distance of the gameObject, it appears or so on... If you have, could you please make a video about proximity/ range based triggers??? That would save my life... ha ha. Thanks in advance and brilliant work again.

Hey man, I've been watching your videos and I'm working on a project. Is it possible to convert the positions from an AR object to world coordinates? I have implemented MapBox so the user can see his location on a mini map. But I don't have a clue how to visualize the position of the AR Objects on the map. Thank you man, appreciate your videos!

[@dilmerv]

Hey man I honestly haven’t done anything like that but let me do some prototyping and see if I can come up with a simple example so added it to my TODO list :) thanks for watching !

Dear Mr. Valecillos, I started watching your videos today. I benefited theoretically, but could not apply it successfully. When I press play AR Camera does not render webcam so, what I recieve is just black screen without any errors. I would be glad if you respond. I use 2019.3.0f6 and have the latest packages. Also I would like to emphasize that I did not experience it while I was using Vuforia.

[@dilmerv]

Correct it won’t render the webcam, you need to build this to the device since AR Foundation doesn’t support that feature just yet.

@@dilmerv I ran the app in my phone, version is 7.1.1, it did not work either. How can I learn if it happens due to my phone, code or unity?

Sir i am using AR Foundation on unity 2018 version 22 and ARcore version 24 , i wanted to ask you that it just detects the plane and places object onto it i want it to stay at a position but it moves along with me , im making a football game :/

[@dilmerv]

Look at the script and do not update the object position after the RayCast was executed, this will keep the object in place after you place it on the plane.

Because the ARRaycast is when we are messing with AR Planes.

[@HowDoYou___]

My PlacedObjects are not appearing at all. I've been at this for a day now and cannot figure it out!

[@HowDoYou___]

I've moved my AR Camera out so the PlacedObjects are in the scene. They appear but are not static, that is, they seem pinned to my screen instead of having an origin.

[@dilmerv]

Are you making sure to place them once the plane is detected and at the Raycast location hit ?
