Determine angle between Object and world mouse position

I need to calculate the angle between the current mouse world position, and an object sitting on a plane.

I’m currently generating the world mouse position, and distance from the camera using:

Ray ray = Camera.main.ScreenPointToRay(UnityEngine.Input.mousePosition);
        RaycastHit hit;
        if (Physics.Raycast(ray, out hit, Mathf.Infinity, layerMask))
        {
            currentMousePosition = hit.point;
            currentMouseDistance = hit.distance; 
        }

I’m then using Debug.DrawLine() to draw a line between the points, and this is working fine. However, I can’t seem to determine the angle.

Vector3 direction = new Vector3(currentMousePosition.x, currentMousePosition.y, currentMouseDistance);
Debug.DrawLine(currentMousePosition, targetObject, Color.red, 5, false);

I’ve tried Mathf.Atan2() which is suggested everywhere, but when I use it the angle produced seems to range from 30-60 degrees, regardless of where the mouse cursor is placed.

I’m not sure why this isn’t working, so any advice or input would be greatly appreciated.

Thanks

Hey man,
If you are not confortable with Atan2(), you can use Vector3.Angle(…) function
