wolf3d VS WolfensteinCGA

There are far better historical sources to study, such as Wolf3D, the classic BSD games, or even Word 1.1.

It took a long time to write that engine and porting the whole thing properly also takes time. It just moves goalposts. Why didn’t he spend 80M on a new AAA game? If he spent any less than that, he certainly can’t draw any useful conclusions.

Have you ever looked over the codebase? It’s plenty large enough to draw useful conclusions from for most people let alone someone with his vast game experience.

Meanwhile, you are drawing bay conclusions with no credentials out evidence. As to actual games, setting aside the fact that Wolfenstein still sees play, loads of popular games are written in JS. Lots of others are in Java or C#. None of these make your case as Haskell, Ocaml, and StandardML (SML) are in the same performance range.

As to your argument about the efficiency of objects, what do you think functional languages use? Lets use SML as an example. There’s real arrays and they are also optionally mutable (yes, there’s linked lists too, but those can be used in C++ too).

Records are basically just C structs (they are immutable by default, but can contain refs which are mutable pointers). They can contain functions because functions are first class without the mess that many languages create.

You associate functions with datatypes which gives you the best part about methods. They also give you a kind of implicit interface too due to structural typing. I’d note that closures are mathematically equivalent to objects.

Finally, modules are everything a language like Java tries to get from classes (and more), but without any of the downsides of classes themselves.

People generally like the JS paradigm of factories and object literals (even if they hate the stuff like dynamic typing or type coercion). StandardML offers the same kinds of patterns, but with sound typing, simpler syntax without the warts, more powerful syntax, and performance in the same range as go or Java.

To me, your argument sounds like the people arguing that goto is better and more natural than looping constructs or the procedural guys arguing against OOP. I think if you messed around with StandardML, it would change your mind about what programming could be in the future.

I'm not used to seeing assembly look like this. What's the wrapper stuff? Looks like C. But I thought you could inline assembly in C like here: https://github.com/id-Software/wolf3d/blob/master/WOLFSRC/DETECT.C

c) The source code was pretty vanilla standard C. No huge assembly. Around 36000 lines of "normal C" (at the time, most of C games were non-portable, you would get near and far pointers or assembly shenanigans you had in Wolf3d source). Only 4 assembly functions (draw a vertical line, a horizontal one, fixed point multiplication and division), and they were already replaced by 4 standard C functions.

id software used raycasting since it's early games like Hovertank 3D, Catacomb 3D and Wolfenstein 3D. heck, even though Doom, Duke Nukem 3D and Blood were majorly using BSP, their most simple and rustic rendering base was through raycasting.

I was wondering that was well since Wolfenstein got a CGA port: https://github.com/jhhoward/WolfensteinCGA

The CGA mode is playable, but pretty bad looking as would be expected. On a Tandy 1000 with the Tandy graphics mode enabled, it looks much better. It'd be cool to be able to run Doom in TGA as well.

There's an 8088 port of Wolfenstein 3D, which is basically the same thing, right? https://github.com/jhhoward/WolfensteinCGA

Attempted this to see how well this project runs on the original IBM PC. Pretty amazing that it runs at all! This port was done by 'jhhoward' - the files can be found on GitHub, I found out about it at the VCF Forums.

I'm honestly still trying to figure out what I want to do with it. I got the compact flash to use with a XT-CF-Lite v4. I'm still trying to figure out what DOS I'd like to use. I can get the OEM MSDOS 3.22 installed onto the drive, but that version's max partition size is 32MB, which isn't ideal when the compact flash is 4GB. FreeDOS supports that size and pre-386, but it was a pain to get it on there and is a bit overkill for a computer this old. Right now I'm considering a later MSDOS, but haven't decided on which one.

As far as software goes I'm waiting on finalizing the DOS before exploring games and development, but it was fun was to be able to run this port of Wolfenstein 3D:

Besides all that I'm thinking of maxing out the RAM (it's 640k now, but can take an additional 128k for video), and maybe adding a real time clock and network card. I do have another Tandy 1000 TX, so I could see how 80's networking worked. That is probably another can of worms though.
