Unity Engine
1

Hi i have a little game which scrolls the background and enemies from the right screen to the left side of the screen.

The scrolling is allways shuttering and not smooth, but more randomly which time is happend.
I have for testing a empty scene with only the 2 alternating background images (re-using) and a few sprites that spawns right and destroys on the left side… thats all on the screen.

All images are 2D sprites.

I have tryed in the Update and FixedUpdate and the Lerp and MoveTowards to with the same result.

On the PC is the shuttering light visible, on the samsung galaxy s8 more then the PC and on the Samsung Tab A (2019) is like 10 fps :rage:

Anyone a idead whats this cause and how to fix it?

  void Update()
    {
        transform.position += Vector3.left * Time.deltaTime * 0.08f;
    }

If you’re only getting 10 fps something is HORRIBLY going wrong.

The only way to truly understand performance hiccups is to start with the Profiler window. Access this from Window → Analysis → Profiler (at least on my version of Unity).

There are fortunately lots of tutorials for getting started, but basically this tool is intended to help you discover what is consuming all your available CPU cycles and making things stutter so badly.

May be there is a loop in your code that’s taking up all your CPU strength
