How do you determine the distance to the surface hit with Physics

The distance member of the RaycastHit structure will have it if the Raycast hits something.

You compute the distance using the known starting position and hit point

The distance is available via a different method call

The maxDistance parameter of the function call will set it.

===========================

The main canvas

The camera

The camera’s parent object

A special VR game object

===========================

It’s a flat image that is aligned to the target surface normal

It’s a long cylinder that is stretched so it just touches the target surface

It’s an empty game object that is aligned perpendicular to the target surface

It’s a flat image that is attached to each potential target surface in the editor at design time

===========================

3DOF tracking is synthetic and not very accurate to begin with

The frame rate is so low the accuracy is bad

Pressing and releasing the button with accurate timing

Mobile accuracy for velocity calculations is low

===========================

It allows you to filter out objects by color

It only does the search if the controller is on one of the masked layers

It occludes the search using a masked image to remove things that can’t be seen

It restricts the objects that are searched to only those that are on the layers selected by the mask

===========================

You want there to be realistic inertia when you pick things up

You have a physics based game and the objects you’re detecting are already physics objects

It’s the only way to detect proximity of physics based objects

You can’t use collisions to detect proximity

===========================

Check for collisions using Colliders

Check for hits against a Raycast

Check for proximity using an OverlapSphere

===========================

They need an ‘interactable’ script

They need a trigger or collision component

They need to have a camera component

They need a special shader
