i need help with this script because I tried debugging it and moveHorizontal is equal to zero how can i change that here is the script below:

//setting up variables
private Rigidbody2D rb2D;

private float moveSpeed;
private float jumpForce;
private bool isJumping;
private float moveHorizontal;
private float moveVertical;

void Start()
{
    //defining variables
    rb2D = gameObject.GetComponent<Rigidbody2D>();
    moveSpeed = 3000000f;
    jumpForce = 60f;
    isJumping = false;

}

void Update()
{ //input for left right movement
    float  moveHorizontal = Input.GetAxisRaw("Horizontal");
    moveVertical = Input.GetAxisRaw("Vertical");

    Debug.Log("moveHorizontal " + moveHorizontal);
    Debug.Log("Velocity " + rb2D.velocity.x + " " + rb2D.velocity.y);

}

void Addforce()
{
    //function that adds a force to rigidbody
    rb2D.AddForce(new Vector2( moveHorizontal * moveSpeed, 0f), ForceMode2D.Impulse);
   

}

private void FixedUpdate()
{
    if (moveHorizontal  > 0.1f || moveHorizontal < -0.1f)
    // if moveHorizontal is greater then 0.1f or if moveHorizontal is less than -0.1f then put a force to a rigidbody
    {
        Addforce();
    }
}

I think you should do the Rb2D initialization a little differently. Like,

    rb2D = GetComponent<RigidBody2D>();
    //We are doing this instead of gameObject.GetComponent<RigidBody2D();

I hope this Helps :smiley:

here is my old projects movement script i hope this helps!

using System.Collections;
using System.Collections.Generic;
using UnityEngine; 
 
public class Move2D : MonoBehaviour {
	public float movespeed = 13f;
	public bool isGrounded = false;
	
	void Update () {
		Jump();
		Vector3 movement = new Vector3(Input.GetAxis("Horizontal"), 0f, 0f);
		transform.position += movement * Time.deltaTime * movespeed;
    }


	void Jump(){
		if (Input.GetButtonDown("Jump") && isGrounded  == true)
		{	
			gameObject.GetComponent<Rigidbody2D>().AddForce(new Vector2(0f, 20f), ForceMode2D.Impulse);
		}
	}
}
