hi all!
I have this issue: I have a camera placed into a fixed position and I need that follow (only rotating) the player.
I made this code:
var dir = target.transform.position - camera.transform.position;
var wantedRot = Quaternion.LookRotation(dir, Vector3.up);
camera.transform.rotation = wantedRot;
and works…
now I wish to manage a smooth rotation, to avoid a rigid rotation between camera and target: so I made this:
var dir = target.transform.position - camera.transform.position;
var wantedRot = Quaternion.LookRotation(dir, Vector3.up);
camera.transform.rotation =
Quaternion.Slerp(camera.transform.rotation, wantedRot, Time.DeltaTime * rotationDamping);
and it works, but the target stutter…
I tried to place the code in the LateUpdate, in the FixedUpdate, but seems that FixedUpdate is better, but not completely solved
I have an idea, but I don’t know how to fix:
should be that for example wanted rot is 10, and with Slerp I get a rotation of 4, in the next frame, the wanted rotation should be 12, but I start from 4, and so I made a Slerp with 8 and not 10 like before, and maybe the next frame is increased and this cause a stutter
The stutter will depend on how fast the target is updating compared to your camera update. For example, if you update the target at 45fps and the camera at 30fps you will get a stutter effect.
It should work if you update the target in Update() and update the camera in LateUpdate(). That means they are both updating at the same frequency but the camera is updating -after- the target has moved.
thank you @tonemcbride !
I had a problem on my game and I tried to test in a simple scene, using the Cinemachine samples,
the update is on Update function, so should not be different
and the LateUpdate seems to be the worst situation
If you’re getting stutter, it will 99% be related to using LateUpdate() on the camera. If you’re using
transform.LookAt(pos);
it will never get the pos in sync with Update()
It sounds obvious, but stick any transforms for the camera right at the end of LateUpdate.
