Game feels jittery when moving and looking (first person)
Hi,
I recently swapped to using physics-based movement (applying forces to a Rigidbody in FixedUpdate) with my normal mouselook (Update) and I like it - however, when you move AND look around, there is a jittery sort of effect that happens. If I walk side to side trying to keep my crosshair on a fixed point, the game feels jittery and laggy. I think it may have something to do with using FixedUpdate vs Update but I don't see why and I'm not sure how to sync them up well.
The movement works as follows:
Vector3 velocity = rb.velocity;
Vector3 velocityChange = (targetVelocity - velocity);
velocityChange.x = Mathf.Clamp(velocityChange.x, -maxVelocityChange, maxVelocityChange);
velocityChange.z = Mathf.Clamp(velocityChange.z, -maxVelocityChange, maxVelocityChange);
velocityChange.y = 0;
rb.AddForce(velocityChange, ForceMode.VelocityChange);
And the mouselook works as follows:
if (axes == RotationAxes.MouseXAndY)
{
float rotationX = transform.localEulerAngles.y + Input.GetAxis("Mouse X") * sensitivityX;
rotationY += Input.GetAxis("Mouse Y") * sensitivityY;
rotationY = Mathf.Clamp(rotationY, minimumY, maximumY);
transform.localEulerAngles = new Vector3(-rotationY, rotationX, 0);
}
else if (axes == RotationAxes.MouseX)
{
transform.Rotate(0, Input.GetAxis("Mouse X") * sensitivityX, 0);
}
else
{
rotationY += Input.GetAxis("Mouse Y") * sensitivityY;
rotationY = Mathf.Clamp(rotationY, minimumY, maximumY);
transform.localEulerAngles = new Vector3(-rotationY, transform.localEulerAngles.y, 0);
}
I tried recording a GIF but the framerate is too low to notice.
