unity how to move something towards a point code example

Example 1: how to make an object point towards the mouse in unity

//Inside your update loop, add the following code:

//First, get the mouse position
Vector2 mousePosition = new Vector2 ( 
  Input.GetAxis("MouseX"), 
  Input.GetAxis("MouseY")
);
//Then, use unity's built-in lookAt function to do all the math for you:
transform.LookAt(mousePosition);

Example 2: how to move towards an object unity

//This will work for 2d or 3d platforms
//Make sure to call in Update or else it wont work
Vector3.MoveTowards(transform.position, taretPos, Qiaternion.identiy)
