Can someone help me?

        camTrans.rotation = Quaternion.Euler(camTrans.rotation.eulerAngles + new Vector3(-mouseInput.y, 0f, 0f));
    }
}

It’s just as your error says. You have a Vector3 variable:private Vector3 moveInput; and a float variable: float yStore = moveInput.y; and then you’re trying to assign the float to the Vector3 variable: moveInput = yStore;This doesn’t make sense. You can’t put a float into a Vector3 variable anymore than you can shove a square peg into a round hole.

Did you perhaps mean to do something like this?moveInput.y = yStore;
You need to think consciously about what each line of code is doing and whether it makes sense.

thanks

But the other way around…

(42,23): error CS1061: ‘Vector3’ does not contain a definition for ‘GetKey’ and no accessible extension method ‘GetKey’ accepting a first argument of type ‘Vector3’ could be found (are you missing a using directive or an assembly reference?)

need help again

You are really just making typos/silly mistakes. Look at the line of code indicated in the error. It doesn’t make any sense.

Cannot implicitly convert type ‘float’ to ‘UnityEngine.Vector3’

I get this error, could someone help me?
This is my code

using UnityEngine;

public class Player : MonoBehaviour
{
    public static Player obj;

    public int lives = 3;

    public bool isGrounded = false;
    public bool isMoving = false;
    public bool isInmune = false;

    public float speed = 5f;
    public float jumpForce = 3f;
    public float movHor;

    public float inmuneTimeCnt = 0f;
    public float inmuneTime = 0.5f;

    public LayerMask groundLayer;
    public float radius = 0.3f;
    public float groundRayDist = 0.5f;

    private Rigidbody2D rb;
    private Animator anim;
    private SpriteRenderer spr;

    void Awake()
    {
        obj = this;
    }


    // Start is called before the first frame update
    void Start()
    {
        rb = GetComponent<Rigidbody2D>();
        anim = GetComponent<Animator>();
        spr = GetComponent<SpriteRenderer>();
    }

    // Update is called once per frame
    void Update()
    {
        movHor = Input.GetAxisRaw("Horizontal");

        isMoving = (movHor != 0f);

        isGrounded = Physics2D.CircleCast(transform.position, radius, Vector3.down, groundRayDist, groundLayer);

        if (Input.GetKeyDown(KeyCode.Space))
            jump();

        flip(movHor);

    }

    void FixedUpdate()
    {
        rb.velocity = new Vector2(movHor * speed, rb.velocity.y);
    }

    public void jump()
    {
        if (!isGrounded) return;

        rb.velocity = Vector2.up * jumpForce;
    }

    void flip(float _xValue)
    {
        Vector3 theScale = transform.localScale;

        if (_xValue < 0)
            theScale.x = Mathf.Abs(theScale.x) * -1;
        else
        if (_xValue > 0)
            theScale = Mathf.Abs(theScale.x);

        transform.localScale = theScale;
    }

    void OnDestroy()
    {
        obj = null;
    }
}

In which line does the error occur? Can you provide the full error message?

Line 78 is missing the reference to the x field.
