help with movement controls

Unity Engine
1

so i want to make it so that this snake (player) moves by the position of the mouse on the screen but when i put a number or even a number variable it gives me a error

Assets\playermovement.cs(13,13): error CS0019: Operator ‘>’ cannot be applied to operands of type ‘Vector3’ and ‘int’

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

public class playermovement : MonoBehaviour
{
    public float f;
 

    // Update is called once per frame
    void FixedUpdate()
    {
        if (Input.mousePosition > ) { }
    }
}

Doesn’t really make sense to do this kind of comparison. A Vector3 is a position in space with 3 components: x, y, z. There really isn’t a proper > for that. You’d want to instead compare to one of its components, so Input.mousePosition.x for instance.

ok…

ok… i might need more help though

    void FixedUpdate()
    {
     /*
we need to translate mouse from screen position to world position
we cannot compare a Vector3 so lets look at .x
if script attached to player then transform is player
    */
        if (Camera.main.ScreenToWorldPoint(Input.mousePosition).x > transform.position.x ) {//move right }
    }
