Hi. I am fairly new to using Unity for 2D games. I am currently making a platformer and when the player is moving the sprite will occasionally “shake like crazy”. This is the script I’m using in Fixed Update.
void FixedUpdate()
{

        float h = Input.GetAxis("Horizontal");
        float xSpeed = Input.GetAxis("Horizontal") * 2.0f;
        anim.SetFloat("Speed", Mathf.Abs(xSpeed));
       
        this.rigidbody2D.AddForce(new Vector2(xSpeed * MoveFactor, 0f));
        // If the input is moving the player right and the player is facing left...
        if (h > 0 && !facingRight)
            // ... flip the player.
            Flip();
        // Otherwise if the input is moving the player left and the player is facing right...
        else if (h < 0 && facingRight)
            // ... flip the player.
            Flip();

      
    }

Do you think you could help me fix it?

Try this character controller script:

using UnityEngine;
using System.Collections;

public class PlayerControllerScript : MonoBehaviour {

	public float maxSpeed = 3;
	bool facingRight;

	void FixedUpdate () 
	{
		float move = Input.GetAxis ("Horizontal");

		rigidbody2D.velocity = new Vector2 (move * maxSpeed, rigidbody2D.velocity.y);

		if (move > 0 && !facingRight)
			Flip ();
		else if (move < 0 && facingRight)
			Flip();
	}

	void Flip()
	{
		facingRight = !facingRight;
		Vector3 theScale = transform.localScale;
		theScale.x *= -1;
		transform.localScale = theScale;
	}
}
