2022-09-13Move towards C23, improve events and vcall macrosMichael Smith
Another big one. Here's a list of things: - Since the upcoming C23 standardises typeof(), use it as an extension for the time being in order to allow passing arbitrary types as macro/codegen parameters. It wouldn't have been a big leap to do this even without standardisation since it's apparently an easy extension to implement - and also, to be honest, this project is essentially glued to Clang anyway so who cares. - Likewise, bool, true and false are becoming pre-defined, so pre-pre-define them now in order to get the benefit of not having to remember one header everywhere. - Really ungodly/amazing vcall macro stuff now allows us to call C++ virtual functions like regular C functions. It's pretty cool! - Events can now take arbitrary parameters and come in two types: regular events and predicates. All this makes the base code even uglier but makes the feature implementation nicer. In other words, it places more of the cognitive burden on myself and less on other people who might want to contribute. This is a good tradeoff, because I'm a genius.
2022-08-16Import Monocypher 3.1.3 + monocypher-rng moduleMichael Smith
This is for somewhat later. I'd always planned to use it - it existed already in earlier private repos, in fact. I just didn't bother to import it here in case it wouldn't actually be needed, but with the way current plans are going, it's definitely going to be needed, so here it is.
2022-07-23Split custom demo data into its own file/featureMichael Smith
Copyright note: the stuff Bill wrote is all still in the other file.
2022-07-23Add keybind lookup codeMichael Smith
Also centralise NEXT_INSN macro, into its own header at least for now.
2022-07-23Add alias management plus input filtering skeletonMichael Smith
Some of the alias stuff was kind of stolen from earlier figuring-out Bill did. More Bill code is also on the way. :^)
2022-06-02Solve the error logging situationMichael Smith
2022-05-30Add basic Portal crosshair colour customisationMichael Smith
Currently only works in 3420 and 5135 and uses hardcoded offsets with a byte pattern sanity check. Future work includes making it more widely compatible, and also doing the crazy thing I wanted to do but gave up on wherein the actual textures and stuff get patched in memory to sync up all the colours. Oh also, a couple of vtables were erroneously made executable, so I went ahead and fixed that while I was at it.
2022-05-03Add entity property finding and L4D warp testingMichael Smith
This was a lot more code than expected, but it might be finally close to time to release the next beta... We'll see if any more rabbit holes present themselves to jump into, though.
2022-04-30Centralise engine access, add Portal FOV changerMichael Smith
- A bunch of stuff is now defined in one header, engineapi.h - engineapi.c is responsible for setting up any interfaces/stuff that's used in more than one place - mkgamedata is pretty much rewritten and now supports nested conditionals - gamedata variables no longer have the gamedata_ prefix because it was just annoyingly long all the time - vcall macros are somewhat revamped and support dynamic (gamedata) indices - Portal 1 FOV can be set anywhere from 75-120 using fov_desired - tested in both the main versions currently used by runners - A few typos were also fixed ("intput," "writeable," "indexes")
2022-04-25Add engine_no_focus_sleep backport, fix codegenMichael Smith
Default gamedata values actually work the way they're supposed to now.
2022-04-24Replace udis86 with a very small x86 decoderMichael Smith
hook_inline() uses the new x86_len() function to get instruction lengths instead of doing full-blown disassembly, which should be a tiny bit quicker, and also removes the next for about 90KiB of lookup tables and such in the final binary. The code-digging logic in demorecord is also rewritten to be opcode-based rather than mnenmonic based. In general, going forward the plan is to always rely on opcodes and thus avoid a bunch of disassembly work every plugin load. udis86 is still in the tree for now to provide dbg_asmdump(), but it's only compiled into debug builds and left out of releases completely. As such, the whole BSD licence statement is also gone from the distribution LICENCE files. There's now also a dbg_toghidra() which spits out a rebased address to look stuff up for proper reverse engineering, which might be more useful than dbg_asmdump() anyway. If nobody ends up using the latter ever again, udis86 could get chucked completely. We'll see. Also shoehorned into this commit are a couple more forgotten copyright year bumps and some general minor cleanup here and there, because I couldn't be bothered wading through all the diff hunks. Oh, and makebindist.bat now makes an effort to make the zip file timestamps predictable/reproducible. That should be a different commit for sure, but oh well too bad.
2022-03-30Make build scripts *slightly* more flexibleMichael Smith
They're still temporary, I promise, but this will make tweaking the toolchain or turning debug builds on and off a lot simpler.
2022-01-06Tidy up stubs, make vstdlib a stub, build on LinuxMichael Smith
Important note: it doesn't WORK on Linux, and there's tons of warnings and stuff, but it's easier to work on when all the compiler output and whatnot is there.
2022-01-06Fix build scripts and codegen on LinuxMichael Smith
SST itself doesn't build, but it's a start! Really interesting is the declaration after a switch label. That's of course invalid, but Clang on Windows never complained. I guess it's an MSVC extension, eh? How annoying. Also, haha yes the script wasn't even executable. Forgot to update-index when I remade the repo, I guess...
2021-12-30Split up os.h, inline functions and fix some typosMichael Smith
2021-12-27Reintroduce autojump codeMichael Smith
2021-12-26Unhide useful commands and allow cheats in lobbiesMichael Smith
This is done through a new "fixes" file which will probably become one of those silly dumping grounds that every project has to have somewhere to put random miscellaneous crap in. These are mainly hidden in L4D2 but they just get unilaterally unhidden if they exist, just to be sure they're accessible. As a bonus, it turns out that unhiding a single cvar also allows us to set sv_cheats 1 in Left 4 Dead 2, bringing an end to the need to port- forward a listen server for co-op practice.
2021-11-20Initial public snapshotMichael Smith
With code from Bill. Thanks Bill!
