I am trying to make the scale of my ground object to be scaling up and down depending on the y position of my mouse.
I get an error called error CS1503: Argument 1: cannot convert from ‘float’ to ‘UnityEngine.Vector3’.
Thanks for all the help.
I am a beginner, I started about a month or two ago.

using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;
    
   using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class MouseToScale : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        float mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition.y);
        Vector3 scaleChange = new Vector3(0f, mousePos, 0f);
        transform.localScale += scaleChange;
        transform.position = new Vector2(transform.position.x, transform.position.y - mousePos);
        
    }
}

Hi, the error is that Camera.main.ScreenToWorldPoint() returns a Vector3 but you are assigning it to a float, it also takes an argument of type Vector3 as well but you are giving it a float, for what you are trying see if you can use the mouse delta with Input.GetAxis instead, as that gives you better numbers to work with
