	Deleted User	where did you find the class names?
	Deleted User	does the engine have some sort of reflection like unreal engine?
	AdrienTD	The class names were the more interesting and ground breaking parts 😃
	AdrienTD	There are some class names left in the EXE
	AdrienTD	And that's because the engine has some way to identify classes
	AdrienTD	When the game is started, it will run several code that will register these classes.
	AdrienTD
	AdrienTD	For example this will call a function that will register the class CKSpeechManager.
	AdrienTD	The first two arguments are IDs for this call.
	AdrienTD	So the game can refer to a class by their ID, which is the case in the game files.
	AdrienTD	Also it associates to the class functions that will create an instance of this class, and functions to destroy ones, which happen to be the same for all classes (DestroyKCL1/2 in the screenshot)
	AdrienTD	Actually, the destructor just calls the virtual destructor from the vft.
	AdrienTD	Also all the registered classes are subclasses to a common class. In my XXL inspector I call it KClass: ```C++ struct KClass { virtual void destructor_placeholder() = 0; virtual char isSubclass(int cls) = 0; virtual void unknown1() = 0; #if XXLVER >= 2 virtual void unknown2() = 0; #endif virtual int getClassGroup() = 0; virtual int getClassID() = 0; } ```
	Deleted User	yeah it's similar in unreal engine
	AdrienTD	I have never used Unreal Engine, but nice to learn this.
	AdrienTD	The KClass also has virtual functions for saving and loading from KWN files.
	AdrienTD	So often KWN files are just files containing serialized instances of these registered classes.

	AdrienTD	Looks more complicated in Unreal than in XXL 😄
	AdrienTD	I see Unreal also has names for data members and functions
