Smooth Follow cam; how to keep camera close, but still retain sideways lag/lerp
So, I wrote this fairly simple camera script , and it works well for what it does, but I would like to limit how far behind the player the camera can "lag" but still retain the "sideways lag".
I want the camera to stay with the player even at high speed, but still lag behind when the target turns.
I want it to behave more like this: https://youtu.be/MigtfNua7O4?t=33
I thought about using two different lerp values, but I'm not sure how to do that.
And, yes, I am aware of Cinemachine, but I want to code this myself..
public Transform target;
public float PosLerpSpeed= 5f;
public float xOffset;
public float heightOffset=3f;
public float distanceOffset=8f;
void FixedUpdate () {
// define wanted camera position
Vector3 offset=new Vector3(xOffset,heightOffset,-distanceOffset);
Vector3 wantedCameraPosition= target.rotation * offset + target.position;
// lerp towards wanted camera position
Vector3 smoothedPos= Vector3.Lerp(transform.position,wantedCameraPosition,Time.deltaTime*PosLerpSpeed);
transform.position = smoothedPos;
// look at target
transform.LookAt(target,target.up);
}

You're pretty much there; all you need to do is separate the movement from the offset, i.e.
//With your other variables
private Vector3 lastOffset = new Vector3 (0f, 0f, -1f);
...
//Then inside your update function
Vector3 offset = new Vector3 (xOffset, heightOffset, -distanceOffset);
Vector3 wantedCameraPosition = target.rotation * offset;
Vector3 smoothedPos = Vector3.Lerp (lastOffset, wantedCameraPosition, Time.deltaTime * PosLerpSpeed);
transform.position = smoothedPos + target.position;
//Remember to keep track of the last offset
lastOffset = smoothedPos;
