How to rotate object to cursor?

Question

 // Take mouse position
 mouse = Input.mousePosition;
 castPoint = Camera.main.ScreenPointToRay(mouse);
 
 // Take coordinates for Vector
 x=castPoint.direction.x;
 y=castPoint.direction.y; 
 
 // And make a direction
 movement=new Vector2(x,y);
 rb.AddForce(movement*speed,ForceMode2D.Force);

But nothing happen In 2D game*

I think this should do what you are asking for.

First add these variables:

      public float RotationSpeed;
      private Quaternion lookRotation;
      private Vector3 direction;

I think this is what you should use as your script:

     public void Update()
     {
         mouse = Input.mousePosition;
          castPoint = Camera.main.ScreenPointToRay(mouse);
         //I'm not sure if castPoint has a position in it or not, but if when you type castPoint.transform.position
         direction = (castPoint.- transform.position).normalized;
  
         //create the rotation we need to be in to look at the target
         lookRotation = Quaternion.LookRotation(direction);
  
         //rotate us over time according to speed until we are in the required rotation
         transform.rotation = Quaternion.Slerp(transform.rotation, lookRotation, Time.deltaTime * RotationSpeed);
     }

I used this script for reference, I don't know what a lot of this actually means (or how Quaternions actually work) but this is my holy grail reference for rotating: https://answers.unity.com/questions/254130/how-do-i-rotate-an-object-towards-a-vector3-point.html

Let me know if that works if if you have other questions.
