# Not able to fire projectiles at mouse position

Hey,

I’m trying to add a simple little system that shoots projectiles to the mouses location on click. I’ve it added and it’s shooting projectiles like I want it to, just not at the right direction. It doesn’t matter where my mouse is, if my character is on the right side of the scene, the projectiles will shoot left and if it’s on the left side, you guessed it - projectiles will fire away to the right.

Any idea what could be causing this? Here’s the relevant function.

`````` void Shoot () {
if (Input.GetMouseButtonDown(0)) {
Vector2 mousePos = new Vector2 (Camera.main.ScreenToWorldPoint(Input.mousePosition).x, Camera.main.ScreenToWorldPoint(Input.mousePosition).y);
Vector2 myPos = new Vector2(transform.position.x,transform.position.y);
Vector2 direction = mousePos - myPos;
direction.Normalize();
Quaternion rotation = Quaternion.Euler( 0, 0, Mathf.Atan2 ( direction.y, direction.x ) * Mathf.Rad2Deg);
GameObject projectile = (GameObject)Instantiate( projectilePrefab, firePoint.position, rotation);
projectile.GetComponent<Rigidbody2D>().velocity = direction * speed;
}
}
``````

Try this

``````  void Shoot ()
{
if (Input.GetMouseButtonDown(0))
{
Vector2 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
Vector2 myPos = (Vector2)transform.position;
Vector2 direction = mousePos - myPos;
direction.Normalize();
float angle =  Mathf.Atan2 ( direction.y, direction.x ) * Mathf.Rad2Deg;
GameObject projectile = (GameObject)Instantiate( projectilePrefab);
projectile.transform.position = firePoint.position;
projectile.transform.Rotate (0, angle, 0);
projectile.GetComponent<Rigidbody2D>().velocity = direction * speed;
}
}
``````

I think I have a better solution

Declare `public float angleOffsetInDegrees`, change it in the inspector to get the desired rotation in degrees.

``````void Shoot() {
if (Input.GetMouseButtonDown(0)) {
Vector2 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition); //Mouse position to world position
Vector2 myPos = new Vector2(transform.position.x, transform.position.y);

//Calculate direction in quaternion
Quaternion targetQuaternion = Quaternion.Euler(Quaternion.LookRotation(Vector3.forward, mousePos - myPos).eulerAngles + new Vector3(0f, 0f, angleOffsetInDegrees));

//Calculate direction in Vec3
