unity ppoint towards mouse code example

Example: 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);
