How do i get a attack offset of the player at a fixed distance in 2D?

Goal: I am trying to create an attack towards the mouse click with an offset of the player.
What works: instantiates the object at the correct angle towards the mouse click.
Whats not working: currently the object is spawned close to the mouse click and not offset.

How can i get it to offset it a fixed distance away from the character while still keeping its angle?

public IEnumerator Attack()
{
    Vector3 mPos = Input.mousePosition;
    mPos.z = Camera.main.nearClipPlane;
    Vector3 worldPosition = Camera.main.ScreenToWorldPoint(mPos);
    float angle_ = (Mathf.Atan2(transform.position.y - worldPosition.y, transform.position.x - 
    worldPosition.x) * Mathf.Rad2Deg);

    float trueAngle_;
    if (angle_ < 0)
        trueAngle_ = UnwrapAngle(angle);
    else
        trueAngle_ = WrapAngle(angle);

    Vector2 cPos = new Vector2(transform.position.x, transform.position.y);
    Vector2 dirVector = new Vector2(worldPosition.x + cPos.x, worldPosition.y + cPos.y);

    GameObject swing = Instantiate(slash, dirVector, Quaternion.AngleAxis(trueAngle_ + 90, Vector3.forward)) as GameObject;

    yield return new WaitForSeconds(.317f);
    Destroy(swing);
}

Instead of trigonometry, use vector math - it’s much easier to use and will do the job just fine :slight_smile:

Vector3 mPos = Input.mousePosition;
mPos.z = Camera.main.nearClipPlane;
Vector3 worldPosition = Camera.main.ScreenToWorldPoint(mPos);

Vector3 direction = worldPosition - transform.position;
Vector3 result = transform.position + direction.normalized * distance;
