jittery when moving screenspace

[brisk owl]

I have a tilemap, a cinemachine camera, a joystick to test mobile movement(which is where you can see issue easily) and a player

using UnityEngine;

public class PlayerTest : MonoBehaviour
{
    [SerializeField] Joystick joystick;
    float movement = 0;
    bool down = false;
    Rigidbody2D _rb;
    private void Start()
    {
        _rb = GetComponent<Rigidbody2D>();
    }
    private void Update()
    {

        if (joystick.Horizontal >= 0.3f)
        {
            movement = 1f;
            //Debug.Log("Right");

        }
        else if (joystick.Horizontal <= -0.3f)
        {
            movement = -1f;
            //Debug.Log("Left");

        }
        else
        {
            movement = 0f;
        }
        // if Joystick down, fall through platforms
        if (joystick.Vertical <= -0.4f)
        {
            down = true;
            //Debug.Log("down true");

        }
        else
        {
            down = false;
        }
        //movement = Input.GetAxisRaw("Horizontal");
    }
    private void FixedUpdate()
    {
        var _currentVelocity = new Vector2(movement * 7, _rb.velocity.y);
        _rb.velocity = _currentVelocity;

    }
}

entire player script

I'm off to sleep now, but I'll have a look in the morning.

appreciate all the help man ❤️

Did you share the video of what that jitter look like?

That would be most helpful.

3-6s in

hard to see in video unless you have vid quality set high

moving from the left->right

I can drop anyone an apk that shows it off also, very obvious in bluestacks or on mobile

[hearty gyro]

BlueStacks?

[brisk owl]

its a phone emulator you can use on computer

[hearty gyro]

Yeah, maybe share the apk via Google docs or something, because I really can't spot any jitter on the video. Maybe only for the trees in the background.

[hearty gyro]

I'd be careful to make sure that it's not an issue with the emulator..

[brisk owl]

I've tested it on my phone quite a bit also

big issue there

[hearty gyro]

Ok. Upload the apk somewhere then. I'll have a look on my phone when I have time.

top link is with everything still on scene

2nd link is same issue but with basically empty and remade everything

cinemachine settings

(tried putting it at late or fixedupdate for update method, same issue)

I remade the player function to only work for transform.position as well, same issue

I have no idea anymore

except maybe its just like this cause low fps

[hearty gyro]

It seems like I need your permission to access the Google drive file...

[brisk owl]

oh sorry, changed the settings now, didn't save the anyone with link can open piece :/

[hearty gyro]

I was a bit busy, so just got to test your apks. Honestly, I'm not sure if it can be any better with 30fps.🤔
Try that: instead of moving your character with velocity, move it via transform in update and see if there's any difference in terms of the jitter.@brisk owl

[brisk owl]

All good man, appreciate the help!

Wasnt any difference transform in update

[hearty gyro]

Then it's probably how it will look like at 30 fps and there's not much you can do.

[brisk owl]

Feels weird that when character animates and not moving in screenspace its smooth

¯_(ツ)_/¯

[hearty gyro]

I think it's more when the camera moves

[brisk owl]

Ya

[hearty gyro]

The reason is probably how our brains interpret the picture. When things move relative to each other, the difference between frames is more apparent.

[brisk owl]

That makes senss
