Hi gentlemen,

I’ve been going nuts over what should be an easy as hell script. On my 2D project i have my character able to walk and run towards right and left. But i don’t want him to be able to run left when his sword is drawn since the enemies only come from right edge of the screen. Here is the script i use:

public class playerMovement : MonoBehaviour {
    public float maxSpeed = 2f;
    public float multiplier = 3f;
    Animator anim;
    Rigidbody2D rb2D;

    void Start () {
        anim = GetComponent<Animator> ();
        rb2D = GetComponent<Rigidbody2D> ();
    }

    void FixedUpdate()
    {
        float move = Input.GetAxis("Horizontal");
        rb2D.velocity = new Vector2(move * maxSpeed, rb2D.velocity.y);
        bool drawSword = (rb2D.transform.localScale.x > 0) && Input.GetButtonDown("Fire1");
        bool run = (Input.GetButton("Fire3"));

        if (move > 0)
            anim.SetBool("walkRight", true);
        else
            anim.SetBool("walkRight", false);

        if (move < 0)
        {
            anim.SetBool("walkLeft", true);
        }
        else
            anim.SetBool("walkLeft", false);

        if (drawSword)
        {
            anim.SetBool("drawSword", true);
        }

        if (drawSword = true && Input.GetKeyDown(KeyCode.R))
        {
            anim.SetBool("drawSword", false);
        }

        if (run && move < 0)
        {
            rb2D.velocity = new Vector2(move * maxSpeed * multiplier, rb2D.velocity.y);
            anim.SetBool("run", true);
        }
        if (run && move > 0)
        {
            if (drawSword == true)
            {
                anim.SetBool("run", false);
                rb2D.velocity = new Vector2(move * maxSpeed, rb2D.velocity.y);
            }
            else
            {
                anim.SetBool("run", true);
                rb2D.velocity = new Vector2(move * maxSpeed * multiplier, rb2D.velocity.y);
            }
        }
        else
        {
            rb2D.velocity = new Vector2(move * maxSpeed, rb2D.velocity.y);
            anim.SetBool("run", false);
        }
}
}

With that script he runs right just fine but never runs left no matter if the drawSword is true or false.

Your very last else statement will override any other velocities previously set, so your prior if (run && move < 0) is effectively meaningless.
