[03:49] <grogbot> <Kumadon> Any recommendations as to which engine to read as a reference implementation?
[03:51] <dreammaster> The plumbers is the simplest example of an engine. There's also a useful guide for creating a skeleton engine at https://wiki.scummvm.org/index.php?title=HOWTO-Engines

[04:04] <grogbot> <Kumadon> I found the wiki told me where but not what or why, so I had started read a few engines and found myself lost in particulars.
[04:05] <grogbot> <Kumadon> So Ill give that engine a read next. Thanks.

[09:52] <grogbot> <Henke37> it's not what i'd recommend as a good engine.
[09:52] <grogbot> <Henke37> it's more like "it's the dumbest, most trivial engine"

[10:26] <grogbot> <Henke37> there is the scumm engine, but that one is the oldest one. which means that it probably hasn't been refactored to obey best practices

[14:42] <grogbot> <sev> @Kumadon what are you looking for?
[14:42] <grogbot> <sev> @Henke37 best practices?

[15:07] <grogbot> <Kumadon> Just something to help me get familiar with the scummvm architecture. I couldnt get a good mental model from reading straight doxygen. Plumbers was a good first read on the basics.
[15:10] <grogbot> <sev> well, it all depends
[15:11] <grogbot> <sev> in short. we have OSystem, hardware abstraction layer, then we have middleware code in common/graphics/audio/video, and finally, there are engines code
[15:12] <grogbot> <sev> each engine is its own beast, often vastly different from other by architecture
[15:12] <grogbot> <sev> if you would like to understand how ScummVM draws things and talks to hardware, testbed engine is your best bet
[15:13] <grogbot> <sev> then, Quux engine from our Wiki and Plumbers are the minimalistic engines with no meat, just the main loop and input
[15:13] <grogbot> <sev> the rest depends on the game engine you would like to work on
[15:14] <grogbot> <sev> what would you like to work on, what is your interest?
[15:16] <-- Some_Person left irc: Ping timeout: 244 seconds
[15:16] <grogbot> <Kumadon> Ive considered trying to reverse a bunch of random titles in the past, but recently found that Eagle Eye Mysteries shipped with full debug symbols.
[15:17] <grogbot> <Kumadon> Which is why I was looking at other engines as examples for getting started.
[15:18] <grogbot> <sev> ah, so the typical workflow for starting an engine is
[15:18] <grogbot> <sev> 1. Copy over Quux, and implement detection by adding detection check sums
[15:18] <grogbot> <sev> 2. Implement loading the main game archive, if game assets are packed in archive.
[15:18] <grogbot> <sev> 3. Display first room background
[15:18] <grogbot> <sev> 4. Add actors
[15:19] <grogbot> <sev> 5. Work on scripting
[15:19] <grogbot> <sev> 6. Sound and other features
[15:19] <grogbot> <sev> I suggest using debug channels and leave as much of trace as possible, it helps greatly in debugging
[15:20] <grogbot> <Kumadon> Yes, thats the roadmap I e been following.
[15:21] --> Some_Person joined #scummvm.
[15:21] <grogbot> <sev> ah, 3a, add objects, e.g. static things, not animations
[15:26] <grogbot> <Kumadon> Thanks again for the pointers!
[16:45] <Strangerke> kumadon: full debug symbols... Sweet :)

[16:52] <grogbot> <rsn8887> Are AGS games playable in Scumm?
[16:54] <dreammaster> Not currently
[16:55] <dreammaster> AGS is whole complicated mess with multiple different versions, and lots of games using third party DLLs for varying special effects. I plan to play around with doing some conversion of the existing AGS3 later this year, but even if I do, it'll only end up supporting a subset of prior AGS games
[16:59] <grogbot> <sev> dreammaster: do you plan to start from scratch or pick up fuzzie's work?
[17:02] <Strangerke> we should remember how the AGS community reacted when fuzzie worked on it, and stay away from them
[17:07] <dreammaster> I'm undecided on all counts. Fuzzies work is a good start, but it's already somewhat refactored, and since it was unfinished, it would be hard to figure out what's missing and properly complete it
[17:09] <dreammaster> The AGS3 source code is available, so I may end up using that, but as said, the past experience with the AGS community was somewhat toxic, though I don't want to necessarily blame the whole community. It might be different this time.
[17:10] <dreammaster> Also, it may be a tad masochistic, but I'm also tempted to pick up the oldest AGS game I can find, and if I can confirm it won't play on the current AGS standalone interpreters, work on disassembling it with the more recent source as a rough guide. :)

[17:52] <grogbot> <SupSuper> laukev7: i think you have to use String::format, we don't have a stream equivalent
[18:05] <laukev7> ok, understood
[18:05] <laukev7> what about the classes in stream.h?
[18:05] <laukev7> I was wondering whether any of those were a direct equivalent? or are they more for file I/O?
[18:07] <grogbot> <SupSuper> yeah they're for files

[19:55] <grogbot> <rvanlaar> I'm hitting a snafu when compiling on ubuntu 20.04. It seems configure doesn't work when only SDL2 libs are installed.
[19:57] <grogbot> <rvanlaar> This is the C snippet in configure: #include "SDL.h" int main(int argc, char *argv[]) { SDL_Init(0); return 0; } Configure completes when I change the include to: #include "SDL2/SDL.h"
[20:08] <grogbot> <rvanlaar> Is scummvm not SDL2 compatible, or is there something else going on?
[20:10] <grogbot> <SupSuper> it should. the SDL2 folder should be included directly, not a subpath

[20:33] <grogbot> <rvanlaar> Thanks for the feedback, it works again.
