Raycast2D "shot off" in the direction of the mouse does not match up with the mouse

I’ve never liked Raycasts but this one really has me stumped. Here’s a picture: (red is raycasts, green is where I clicked the mouse)

Here’s my code: (2D Raycast at line 121

using System.Collections.Generic;
using UnityEngine;

public class PlayerScript : MonoBehaviour {

    public Rigidbody2D rb;

    public Animator anim;

    public Transform spriteRoot;
    public Transform firingPoint;
    public Transform aimAssist;

    public GameObject bulletImpact;
    public LayerMask BulletRayMask;

    public Camera mainCamera;

    public float maxSpeed;
    public float speedAccel;

    public bool facingLeft;
    public bool facingRight;
    public bool sliding;

    private Vector3 mousePos;

    public GameObject debugCube;

    void Start () {
        rb = GetComponent<Rigidbody2D> ();
    }

    //For Input
    void Update() {

        mousePos = mainCamera.ScreenToWorldPoint(Input.mousePosition);

        //----SHOOTING----//

        if (Input.GetMouseButtonDown (0)) {
            ShootBullet (new Vector2(firingPoint.position.x, firingPoint.position.y), new Vector2(mousePos.x, mousePos.y));
        }

        //----END----//
    }

    //For Physics
    void FixedUpdate () {

        //----AIMING----//
        if (mousePos.x < transform.position.x && !sliding) {
            facingLeft = true;
            facingRight = false;
        } else if (mousePos.x > transform.position.x && !sliding) {
            facingLeft = false;
            facingRight = true;
        }

        if (facingLeft) {
            spriteRoot.localScale = new Vector3(-5, 5, 5);
            aimAssist.rotation = Quaternion.LookRotation (Vector3.forward, mousePos - transform.position);
        } else if (facingRight) {
            spriteRoot.localScale = new Vector3(5, 5, 5);
            aimAssist.rotation = Quaternion.LookRotation (-Vector3.forward, mousePos - transform.position);
        }

        anim.Play ("Aim", 1, (1f/180f)*(aimAssist.eulerAngles.z));

        //----END----//

        //----MOVEMENT----//

        if (Input.GetKey (KeyCode.LeftShift)) {
            sliding = true;
            anim.SetBool ("Run", false);
            anim.SetBool ("BackwardsRun", false);
            anim.SetBool ("BackSlide", true);
        } else {
            sliding = false;
            anim.SetBool ("BackSlide", false);
        }

        if (Input.GetKey (KeyCode.A) && !sliding) {

            if (facingLeft) {
                anim.SetBool ("Run", true);
                anim.SetBool ("BackwardsRun", false);
            } else if (facingRight) {
                anim.SetBool ("Run", false);
                anim.SetBool ("BackwardsRun", true);
            }

            if (rb.velocity.x > -maxSpeed)
                rb.AddForce (new Vector2 (-speedAccel, 0));
           
        } else if (Input.GetKey (KeyCode.D) && !sliding) {

            if (facingLeft) {
                anim.SetBool ("Run", false);
                anim.SetBool ("BackwardsRun", true);
            } else if (facingRight) {
                anim.SetBool ("Run", true);
                anim.SetBool ("BackwardsRun", false);
            }

            if (rb.velocity.x < maxSpeed)
                rb.AddForce (new Vector2 (speedAccel, 0));
           
        }

        if (!Input.GetKey (KeyCode.A) && !Input.GetKey (KeyCode.D)) {
            anim.SetBool ("Run", false);
            anim.SetBool ("BackwardsRun", false);
        }

        //----END----//
    }

    void ShootBullet(Vector2 spawnPos, Vector2 directionPos) {
        RaycastHit2D hit = Physics2D.Raycast (spawnPos, directionPos, 1000f, BulletRayMask);
        if (hit.collider != null) {
            GameObject bulletImpactObj = GameObject.Instantiate (bulletImpact, new Vector3 (hit.point.x, hit.point.y, 0), Quaternion.identity);
        }
        Debug.DrawLine (new Vector3(spawnPos.x, spawnPos.y, 0), new Vector3(directionPos.x, directionPos.y, 0), Color.green, 5f, false);
        Debug.DrawLine (new Vector3(spawnPos.x, spawnPos.y, 0), new Vector3(hit.point.x, hit.point.y, 0), Color.red, 5f, false);
        GameObject.Instantiate (debugCube, new Vector3(directionPos.x, directionPos.y, 0), Quaternion.identity);
        anim.SetTrigger ("GunKickback");
    }
}

I originally thought the mouse coords were inaccurate. The debug lines, however, show that the mouse positions are correct, but for whatever reason, setting off a Raycast in the direction of the mouse is horribly inaccurate. I can’t wrap my head around why. Can someone with a better understanding of Raycasts explain what in the hell is going on? Thanks.

Hey, guess what? It’s another case of “cannot solve for 3hrs until posted”. My problem was at line 121, spawnPos needed to be subtracted from directionPos. If a mod sees this thread, feel free to delete it.
