Answer 1

See how to deal with enums correctly: https://en.cppreference.com/w/cpp/language/enum
The kind of enumeration you use in your code is called Scoped enumerations. To use it, you must declare a Direction like so: . If the enumeration is declared as you have, then you need to access it without specifying the Direction. enum class Direction {...
