Here is the script for the animation workshop player character in Bertozzi's animation workshop demo.

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

public class ControlPlayer : MonoBehaviour {

	private Rigidbody2D myPlayerRB;
	private Animator myAnimator;

	[SerializeField] private int speed;

	private bool facingRight;

	void Start(){
	
		myPlayerRB = GetComponent<Rigidbody2D>();
		myAnimator = GetComponent<Animator>();
		facingRight = true;
	
	}

	void FixedUpdate(){

		float horizontal = Input.GetAxis ("Horizontal");// returns a value between -1 and 1)

		//Debug.Log ("horizontal is :" + horizontal);
		ControlElf (horizontal);
		FlipElf (horizontal);


		// set a trigger to cause the jump animation in the animator
		if(Input.GetKeyDown(KeyCode.Space)) myAnimator.SetTrigger("jump");

	}


	void ControlElf(float horizontal){

		myPlayerRB.velocity = new Vector2 (horizontal * speed, myPlayerRB.velocity.y);
		myAnimator.SetFloat ("elfSpeed", Mathf.Abs (horizontal)); // set horiz to positive and send to animator

	
	}


	void FlipElf(float horizontal){
	
		if ((horizontal > 0 && !facingRight) || (horizontal < 0 && facingRight)) {
			Vector3 elfScale = transform.localScale; // current pos
			elfScale.x *= -1; // reverses pos and neg of x
			transform.localScale = elfScale;
			facingRight = !facingRight;
		
		}
	
	}

}
