Integers can't be implicitly cast to enum types. You can however use an explicit cast if you wish.

Fun1(NxForceMode(NX_FORCE|NX_FORCE));

I do however recommend doing what you did for Fun0, i.e. write the function to take an uint instead of an enum value. This is because you do not really want an enum value, but rather a combination of them.
