Now we have the first version of the Firing system working, we have to take into account that the bullet flag (masks) system is not as its said in the wiki, to be able to perform (detect) a collision between 2 objects (A and B) should happend: A->FilterGroup & b->FilterMask). Note that we need to set the objects to be able to collide against RAYCAST element if we want to be able to raycast them
