When i move using the joystick the camera moves too - How to make dead zones?

Hello. I’ve made a joystick for my first person mobile game, but whenever i touch it or if i touch the jump and sprint buttons, the camera moves too, making it impossible to play.

How do i make a dead zone on the joystick and buttons area so these areas won’t move the camera?

This is the script that moves the camera with mouse or touch inputs:

using UnityEngine;

public class FirstPersonLook : MonoBehaviour
{
    [SerializeField]
    Transform character;
    public float sensitivity = 2;
    public float smoothing = 1.5f;

    Vector2 velocity;
    Vector2 frameVelocity;


    void Reset()
    {
        // Get the character from the FirstPersonMovement in parents.
        character = GetComponentInParent<FirstPersonMovement>().transform;
    }

    void Start()
    {
        // Lock the mouse cursor to the game screen.
        //Cursor.lockState = CursorLockMode.Locked;
    }

    void Update()
    {
        // Get smooth velocity.
        Vector2 mouseDelta = new Vector2(Input.GetAxisRaw("Mouse X"), Input.GetAxisRaw("Mouse Y"));
        Vector2 rawFrameVelocity = Vector2.Scale(mouseDelta, Vector2.one * sensitivity);
        frameVelocity = Vector2.Lerp(frameVelocity, rawFrameVelocity, 1 / smoothing);
        velocity += frameVelocity;
        velocity.y = Mathf.Clamp(velocity.y, -90, 90);

        // Rotate camera up-down and controller left-right from velocity.
        transform.localRotation = Quaternion.AngleAxis(-velocity.y, Vector3.right);
        character.localRotation = Quaternion.AngleAxis(velocity.x, Vector3.up);
    }
}

Camera stuff is pretty tricky… I hear all the Kool Kids are using Cinemachine from the Unity Package Manager.

Cinemachine definitely handles ALL the stuff any common camera controller would need, such as dead zones.

There’s even a dedicated Camera / Cinemachine area: see left panel.

If you insist on making your own camera controller, do not fiddle with camera rotation.

The simplest way to do it is to think in terms of two Vector3 points in space:

  1. where the camera is LOCATED
  2. what the camera is LOOKING at
private Vector3 WhereMyCameraIsLocated;
private Vector3 WhatMyCameraIsLookingAt;

void LateUpdate()
{
  cam.transform.position = WhereMyCameraIsLocated;
  cam.transform.LookAt( WhatMyCameraIsLookingAt);
}

Then you just need to update the above two points based on your GameObjects, no need to fiddle with rotations. As long as you move those positions smoothly, the camera will be nice and smooth as well, both positionally and rotationally.

You use the Input System package, not legacy Input. You get settings for deadzones etc etc etc just handed to you.
