var hit : RaycastHit;

function Update() {

 if(Input.GetMouseButtonDown(1)){
 
     Build();
 
 }

}

function Build() {

 if(HitBlock()){
 
     var cube = GameObject.CreatePrimitive(PrimitiveType.Cube);
 
     cube.transform.position = hit.transform.position + hit.normal;
 }

}

function HitBlock() : boolean
