How to Set a cut off point where I cant click on my object

Question

I'm setting up a collectables sort of game and I have been doing a little collision detection so when I click on my note that I want to collect it recognises it. However I can click on my note from 100 meters away! how do I make it so I have to be wit$$anonymous$$n a certain distance for example 2-3 feet until it will recognise me clicking on it?

If you're using raycasting you can set the maximum distance for the cast.

C#

    RaycastHit rInfo; //used for checking what the raycast $$anonymous$$ts
    float maxDistance = 3; //in meter units 
    if(Physics.Raycast(Camera.main.ScreenPointToRay(Input.mousePosition),out rInfo,maxDistance)){
         if(rInfo.collider.CompareTag("objectTag")){
             //do stuff
         }
     }
