Jittery movement of sprite on device
I have a 2D sprite that is moved by the following simple code:
var DurationInSeconds = 3f;
public void Update()
{
progressTime += Time.smoothDeltaTime;
transform.position = Vector3.Lerp (origin, destination, progressTime / DurationInSeconds);
}
In the editor/newer Android devices, this works well.
On a particular device (Samsung Galaxy Tab 2), the movement of this sprite is jittery and does not seem smooth.
I've seen numerous questions regarding jittery or stuttered movement with no real answers on how it can be resolved.
Different devices will have different framerates. I would suggest using FixedUpdate() instead of Update() and updating the position using Time.fixedDeltaTime. Unity will call FixedUpdate() independently of the framerate, so it should look much more consistent on different devices.
