You guys don't realize that back in the late '90s and early 2000s there was still a lot of incorrect thinking that violent video games and movies directly caused kids to become violent and psychotic. This has since been disproven via psychological studies, but it was a common talking point back during that era. In fact you can still see some people clinging on to that incorrect belief to this day if you ask enough people.

I guess it was mostly issue of early gamedev as there were no engines like unity back then and I think people were following mostly the idea "don't fix what is not broken" allowing thus weird structures in code and logic just to make it done instead of banging their head to make it pretty. I recently starting to find this approach relatively viable if only certain team works on the project and until the point you decide to create it more maintainable. So currently my opinion on code is: First implementation can be anything that works, if features update starting to touch that piece of code a lot it will require revision.

@tomquareme3787

Probably because a switch statement is faster than doing a vtable lookup for polymorphism. For a switch statement the compiler generates a jump table and there is no indirection of code; you just jump to the code which needs to be executed. In a vtable you have an indirection to another method with an extra cost of dereferencing a pointer. If I recall correctly virtual methods can also cause cache misses due to the vtable lookup, dereferencing and indirection. The use of a switch statement here probably serves as an optimisation. In game programming, especially back in the days, it is common practice to ditch virtual methods in favour of switch statements, use array based data structures instead of pointer-based ones like linked lists.

@markminch1906

6 ай бұрын

People keep saying this and implying that its like intern level code, but it really just shows how little exposure you have to anything outside of OOP code and don't understand c++ that well. using Switch statements are way faster than performing dynamic dispatch using inheritance. When using an dynamic function in C++ you are working with a pointer that has to be dereferenced, which is slow, then you have to perform a look up on the VTable to find the right function. And if that isn't bad enough you can't inline dynamic functions. Switch statements can call functions that are able to be inline and don't have to use a VTable, now normally you would have functions inside of the switch statement that are all in one compilation unit, and this stays clean because you can look at all the different implementations of the gun in one file, which is quite nice for code read ability, unlike a lot of OOP code where multiple classes exist in different cpp files and you have to go from file to file across your code base to see how different versions of the the inherited functionality is used. There are lots of good reasons to use procedural programming practice, along with learning functional programming practices, I recommend not calling code messy just because it doesn't conform to the only programming style you seem to know @@n00bma5ter69

Not too many comments, but you don't always need them. I also didn't see any truly scary or horrible C++ concepts (no sign of the dreaded reinterpret_cast etc. From what I can remember) and I understood about 90% of it, despite not really being a C++ expert. Can't quite remember what that file did, but I think it was logic governing humans interacting with different types of object in the game world e.g. getting into a car, getting out of a car, what happens if you encounter another pedestrian and bump into them etc.

As much as Unity annoyed me and felt like a cheap toy, the way you structure your scripts and attached them to things is so much more intuitive than Unreal. At least at first. Unreal gets very messy very quickly when you break out the C++. It's non-standard syntax (with many things hidden from you) and you don't attach the code to a game object, rather the code IS the game object. Just like how the Blueprint in the editor IS the game object also. You can't really go "half and half" in Unreal like you can in Unity. Or at least I haven't quite figured out how yet.

What you are seeing is the labels given by the person who has reverse engineered the purpose of each "thing", not the original labels by the rockstar programmers. When you disassemble a binary file, you don't have the luxury of retaining any useful labels or comments (sometimes all you have are some unmolested cleartext strings e.g. names of some external .dll files) so you've just got to add your own labels as you discover what each structure does. One hell of a task, and they did a really good collaborative job on this one.

It's about debugging. If you have several lines of code, it is much harder to find errors than in single lines. If you break it down all the way to super small methods, you can check each and find errors much quicker. Between 1/4 and 1/2 of programming time is spent on debugging. So minimizing this is a huge plus!

Your voice is so cool! it feels like watching a movie

Perfect review, it's a lack of such things with such projects on the Internet

A game I know called Let It Die has Enums that the game signature was dumped so we found value types, but no source code, the enums would increment from 0 and the last enum would actually be called MAX, generally setting any enum to the MAX enum value would crash the game because there was no code built around MAX just everything that came before it

9:25 Wouldn't that be because the getters and setters (or similar) that they would have had in the original code probably was inline? I'm guessing you had something like pDriver->SetVehicle(this); but since it was probably defined in the header it was optimized away at compile time into simply an inline assignment. Thus when the project owners reverse engineer it, they only see the inlined version? I feel that's just common sense for C++ generally.

for the heli section at 6:40 I believe the Find Target section is to enter a heli, but if heli status is Shot Down then you cant enter the heli. then all the cases are different ways you are able to path to or enter the heli. which is why Take Off is after that block of code.

A lot of game programming in comparison to usual software programming I noticed so far is, if the game doesn't need to be maintained (single release), you can throw a lot of etiquette away. Using switch case instead of classes, changing member variables from other objects, and otherwise very unusual solutions to problems are more common than I first expected. After all, having a consistent code structure will help in the first 75% of development, and help with diagnosing bugs on the latter 25%, but the number one focus really is to deliver something playable. The client (the player) experience is the same if the state machine is its own class with scripts or just a switch with 40 statements lol. Of course, this doesn't quite apply to MMOs and online games and moddable games and frameworks/engines, but it's the main idea.

I think I just had a "wait its all basically if-else statements - always has been" kinda moment. I was turning my nose at it until I realised I kinda agree with it, being a rust convert, throwing away inheritance all together, you probably end up using enums/tagged unions to handle sum types anyway, but this seems kinda loose in c++. Does c++ have interfaces, I mean it has "contracts" (was it?) for its type constraints, are they like traits/interfaces?

An interface is just an idea in C++ unlike in other OOP languages that don't allow multi-inheritance for class types. But it is usually allowed to implement multiple interfaces, that's why other languages need the distinction. In C++ you just inherit from interfaces because they're classes. An interface in C++ is just a class where all member functions are pure virtual, and there are no data members. Also concepts are another way to implement the idea of an "interface" in C++, but it's for static polymorphism, not for dynamic polymorphism. C++ is not strictly an OOP language, so it's other major paradigm is "generic programming" which is used to implement the standard library, and for which concepts were designed for mainly.

The codebase is pretty much similar to how Flyff is built. The naming convention etc.

Comments, variable names, function names etc can't be retrieved via decompilation / reverse engineering, unless debug symbols are present. So all of the comments and names of everything are likely solely attributable to the folks that did the reverse engineering.

RESPECT to those coders :)

This is interesting, but I think it would also be neat to look at the code that connects those logical functions to the visual character entities that display on the screen.

Would be interesting to see a Code Review of World of Warcraft Vanilla

I wish my college professors gave us real life examples like this!! They taught us inheritance, class, object etc but never really taught us how they are implemented in the real world.

Was looking at the assembly for Pokemon TCG on Gameboy and was surprised they just listed the names of the cards in the card object source lol

If a 00s game had this amount of code lines, just imagine gta vi...

Code is very modularised with inheritance and good naming conventions
