Avoid repeating code?

Hi guys, I have this code:

    function checkForButtons()
    {
        var ray = Camera.main.ScreenPointToRay (Input.mousePosition);
        var hit : RaycastHit;      
               
        if (Physics.Raycast (ray, hit, 200))
            {
                var objecthit:Transform = hit.transform as Transform;
                   
                if (hit.collider.name == "button_start")
                {
                    print ("object clicked!");
                }
            }          
    }

Plain and simple way to detect a touch on an object, the problem here is that I have multiple objects with different names (or tags) that need to detect the touches, how can I
use this code without re writtting it for every single object?

Write a generic version of this script:

#CheckForButton.js#

function Update()
{
    var ray = Camera.main.ScreenPointToRay (Input.mousePosition);
    var hit : RaycastHit;      

    if (Physics.Raycast (ray, hit, 200))
        {
          hit.transform.SendMessage("Touched", hit, SendMessage.DontRequireReceiver);
        }          
}

Then put your code on the actual object being touched in a function Touched(hit : RaycastHit) - if you need to pass more parameters you would make up a class and put the hit as one of its members and then send an instance of that class to Touched.
