Make UI or Image following/facing smoothly to camera - like the Unity VR Splashscreen

Hi!
I'm asking myself how to make a UI or Image following smoothly & with some delay the movement of the VR-Camera / Headset - just like the Unity build in Splashscreen does ?

Thankful for every hint

 

Compute the position out in front of the player, and measure the distance between that and your current billboard position. If it's close enough, leave it alone. If it's farther away, then move it using something like SmoothDamp with generous damping parameters.

 

Hey, thank you for the reply !! Altough i'm probably one of the worst coders on earth -> i'll try it!!

 

So - got at least a working script -> i attach this script to the object i'd like to follow/face the camera

Code (CSharp):

1. public Camera Camera2Follow;
2. public float CameraDistance = 3.0F;
3. public float smoothTime = 0.3F;
4. private Vector3 velocity = Vector3.zero;
5. private Transform target;
6.  
7. void Awake()
8. {
9.     target = Camera2Follow.transform;
10. }
11.  
12.  
13. void Update()
14. {
15.     // Define my target position in front of the camera ->
16.     Vector3 targetPosition = target.TransformPoint(new Vector3(0, 0, CameraDistance));
17.  
18.     // Smoothly move my object towards that position ->
19.     transform.position = Vector3.SmoothDamp(transform.position, targetPosition, ref velocity, smoothTime);
20.  
21.     // version 1: my object's rotation is always facing to camera with no dampening  ->
22.     transform.LookAt(transform.position + Camera2Follow.transform.rotation * Vector3.forward, Camera2Follow.transform.rotation * Vector3.up);
23.  
24.     // version 2 : my object's rotation isn't finished synchronously with the position smooth.damp ->
25.     transform.rotation = Quaternion.RotateTowards(transform.rotation, target.rotation, 35 * Time.deltaTime);
26. }

While the position dampening works perfect, i'm struggling with a desired "dampening" rotation of my object following the camera's rotation.

Using the version 1 to rotate my object -> the object is always facing to the camera...works but no "smooth" rotation.
Using the version 2 to rotate my object -> the rotation is smoothed out but it i'd try to end it synchronously with the position dampening....same when using smoothTime instead of 35 * Time.deltaTime

hmmm i know why it's not in-synch but i don't know how to "synchronize" the two...any ideas / hints ?

 

Got it!!!
now i'm using on both: smoothTime * Time.deltaTime

 

Sorry for warming up this thread but i got stuck into a "problem".

I'll try to keep the object looking at the camera at a fixed heigt ( Y-value) - works fine the update function is as following:

Code (CSharp):

1.  
2. void Update()
3. {
4.    target.position = Camera2Follow.transform.TransformPoint(new Vector3(0, 0, CameraDistance));
5.    transform.position = new Vector3(target.position.x, 0.5f, target.position.z);
6.  
7. // try to get rotation version 1:
8. transform.LookAt(transform.position + Camera2Follow.transform.rotation * Vector3.forward, Camera2Follow.transform.rotation * Vector3.up);
9. // try to get rotation version 2:
10. transform.rotation = target.rotation;
11. // doesn't work ->
12. transform.rotation.y = target.rotation.y;
13. }
14.  

Both versions will rotate all axis x / y / z ... and version 3 doesn't work

But i'd like to rotate ONLY the y axis and got lost in the Quaternion / Eulers / Vetcor 3 jungle

Thankful for every hint !!

 

Hi

Sorry for necro this thread but this could help.
Just keep y rotation of your object in your look at target.

Code (CSharp):

1. private void Update()
2. {
3.  
4.    
5.         Vector3 targetPosition = camera.transform.TransformPoint(new Vector3(0, 0, distance));
6.        
7.         transform.position = Vector3.SmoothDamp(transform.position, targetPosition, ref velocity, smoothTime);
8.         var lookAtPos = new Vector3(camera.transform.position.x, transform.position.y, camera.transform.position.z);
9.         transform.LookAt(lookAtPos);        
10.  
11.        
12.  
13.    
14. }
