Type Of Refactoring Done

Removing Conditional With Ploymorphism

Improvements Made

• Four new classes - BothWorldPlayerType, SingleplayerWorldPlayerType, MultiplayerWorldPlayerType, and NoneWorldPlayerType - have been created.
• The from() method in each of the new classes takes a SaveGame object as input and returns an instance of the corresponding WorldPlayerType.
• The from() method in the WorldPlayerType class has been modified to return an instance of one of the new classes instead of a WorldPlayerType object.
• The if-else statement in the from() method has been modified to create an instance of the appropriate new class instead of returning a WorldPlayerType object.

Overall, the changes involve refactoring the WorldPlayerType class to use polymorphism instead of a conditional statement to determine the appropriate behaviour based on the state of the SaveGame object. The result is a more modular and extensible code structure.
