GameInteractor is meant to be used for interacting with the game (yup...).
|
|
It exposes functions that directly modify, add or remove game related elements.
|
|
|
|
GameInteractionEffects.cpp is used when code that needs these
|
|
functions also need a check wether a command can be run or not.
|
|
|
|
If these checks need to happen wherever GameInteractor functions are needed, the
|
|
GameInteractor functions can be called directly.
