Item Collection in Unity3d game script

Well there is two ways to do it either using the OnControllerColliderHit

or By using a Trigger  

var cube_num = 0;
function OnControllerColliderHit(hit:ControllerColliderHit)
{   
    if(hit.gameObject.tag == "cube")
    {   
        
        Debug.Log("Zam Gets a HoneyComb");
        Destroy(hit.gameObject);
        cube_num++;
        
    }
}//END FUNCTION ONCONTROLLERCOLLIDERHIT

Using Trigger

var cube_num = 0;

function OnTriggerEnter(other: Collider) {
    if (other.gameObject.tag == "cube") {
        Destroy(other.gameObject);
        cube_num++;
        Debug.Log(honey_num);
    }
}
