this is fantastic , is possible to get a tutoral for knobs and levers?

For some reason my button visual is floating in the air to the right when I start the game, when I remove the Lerp section it stops.

i am seeing trouble regarding the event listeners. you do not have anything in "hoverEntered" yet you add a listener to it? I am attempting to make this button on a wall, and i cannot get the button to even detect when i hover, select, or exit hovering. im currently trying to flip it on its side and reproduce your exact video, but it, so far, has not being working to my expectations. I am currently using unity 22.2.1f1, with the most up to date XR toolkit download available

Another fantastic tutorial, Valem. Merci!

For the very last part, I found that I had to change the code slightly to prevent the cube from moving if I poked it from below. Instead of...

if(pokeAngle < followAngleThreshold)
{
isFollowing = true;
freeze = false;
}
}

I went with....

if(pokeAngle > followAngleThreshold)
{
isFollowing = false;
freeze = true;
}
}

And that worked for me.

Thanks again, Valem!

Great! How can I add sound that can be heard once the button is pressed?

great video！but how about use XR Poke Follow Affordance in 2.3 final version？

Takk!

Love your videos valem! Also here’s an idea, can you make a video on a backpack system for vr?

Yeah Mr.Valem! Yeah button!

my project is Half way Done, Do You Recommend to Upgrade XR Tool kit
