NULL is not a valid parameter or your engine would crash and burn.

Whenever you need to pass a ton of parameters it is better to make a structure with those parameters as its members and pass a reference to that structure.
Why not pass by address, that way you can pass a NULL?
Always use references when NULL is invalid. Use pointers only when NULL is a valid parameter.
