Unity VR Tutorial 2018 - Grab / release object for Google cardboard

On this tutorial I will show a simple way to grab and release an object on Unity for google cardboard.
This video was made in 2018 and as VR still new to work with it may changes over the time how to set up but for now this is working fine, I am being able to create a lot of fun game mechanics using these techniques.

How do i make it so there are multiple objects to pick up

[@yasminadrianasanchez2415]

Thank you so much, this help me a lot😊

[@syedaalena7902]

Which button youre presing for grab and release from controller?

[@atiqahrosslan]

Why I cannot interact with the ball? However, I can grab the ball without interact with the ball.

[@shivamhire9869]

I did some modification to those scripts and came with a alternative game type where we pick up and carry objects to another place to trigger a event like "Open the door when cube place on platform". Also i integrated a movement script that can be used via a X-box controller . The only issue i have with movement is that the player moves irrelevant to the direction of the head. Great Video . Subscribed and liked. would appreciate if you could shed some light on the movement issue i am having. Keep Developing ..cheers.

Hi Shivam, Thanks for watching. About the issue with the movement, I had the same and it took me days to figure it out. Have a look on this video kzbin.info/www/bejne/i3PSqKR9l79sl5Y it might help you with the controller. If does not help you let me know we can figure this out.

@@xlaugts151 Tried this and works marvelously . Did a few Tweaks and now i can pick all the objects that are attached to a certain script called "grab_able" . Using this in making a puzzle game for placing shapes on their respective platforms to unlock the next level. Thanks for these tutorials .. you are a life saver.

The type or namespace name 'Grab' could not be found (are you missing a using directive or an assembly reference?) .NEED HELP :)

Hello, iam trying to make description text apear when i facing the object. For example, when i am facing the BOX, will apear description in the frame "It is A Cube" and if i am facing the Ball it appear "It is a Sphere Object". Do you know to to do this?

[@xlaugts151]

Hi Helmi, Let's see if I understood right. So if we look at the cube it will pop up a message saying something like "This is a Cube" is that what are you trying to do ? If yes, I have other people asking for that and expect a tutorial about that soon. Thanks my friend

[@JoshyHJoshy]

Excellent Tutorial. One question: The "Event Trigger" component is a Unity component. Right? So, can we use the "Pointer Click" events and the rest of them in a regular Unity project or do we necessarily have to import GVR so we can have a reticle pointer interaction?

[@xlaugts151]

Hi H Miri, Yes you can, those GVR components are only for VR, but the onClick and PointerClick you can use in a regular project. Just the onPointer I'm not sure how it's going to work without the reticle pointer. I'll have a look how it could work and let you know once I discover. Thank you! :)

[@manishabalani6427]

can you tell me if I want to place the ball in the new position only and not bring it back to original position what modifications need to be done in the script?

[@chuy6380]

Hello, I have been following your tutorials flawlessly until here. When I grab the ball, it picks it up so fast and puts it back. I have to tap once on my Mac air to be able to grab it because a click grabs it and puts it back instantly. When I am able to grab it, I can tap again to put it back and if I tap again without looking at it, it grabs it again. I have to walk away and tap a few times for it not to grab it. Same thing when simulating on phone. Not sure what the issue is. I have gone over the steps several time.

[@xlaugts151]

Hi Jesus, Have a look on this video kzbin.info/www/bejne/i5-2h4FvbqZ3prs On this video we improve the grab and release ball system it might help with your problem. I add few more steps to make the player grab and release a the ball.

[@nicologiardini99]

Hi, I have a problem releasing the ball .. it doesn't work. I can't understand why. I tried to review the video but I don't understand why

[@edafeclintiduh3754]

Hi, I understand all that you did and want to say thank for being detailed in your explanations. However, my question is how can I grab an object and drop it in any location within my scene.

[@xlaugts151]

Hi Edafe, in your case you want to drop the object and not trow it right ? There are 2 ways I can think of doing it, of course just writing here wont be possible to explain. I can do a video showing it, thanks for the idea hahaha

How can we grabb an object without clicking on the object juste by the reticle pointer
