2023-08-02Make various preparations for upcoming featuresMichael Smith
A lot of this is random WIP from a while back, at least a month ago, and is being committed now to get it out of the way so that other patches can be brought in and integrated against it without causing headaches. Also rolled into this commit is a way to distinguish plugin_unload from exiting the game. This is required for another soon-to-be-integrated feature to avoid crashing on exit, and could in theory also be used to speed up unloading on exit in future. While we're at it, this also avoids the need to linearly scan through the plugin list to do the old branch unloading fix, because we can. Rough summary of the other smaller stuff I can remember doing: - Rework bitbuf a bit - Add some cryptographic nonsense in ac.c (not final at all) - Introduce the first couple of "chunklets" libraries as a sort-of subproject of this one - Tidy up random small bits and bobs - Add source for a small keypair generation tool - Rework democustom to be very marginally more useful
2023-06-10Remove some paranoia about missing commandsMichael Smith
There's absolutely no reason these ever wouldn't be there.
2023-06-10Prune some comments and tidy up other minor thingsMichael Smith
2023-05-16Do some pedantic spring cleaningMichael Smith
- Use const in more places where it makes sense - not absolutely everywhere because it can get a bit annoying - Make all the instruction search loops a bit more readable by casting the function pointer into a temporary variable to loop over - Add a few more doc comments and fix a typo or two - Make that RTTI thing flexibly-sized, finally - Don't include gamedata.h in vcall.h for no reason; consequently include gamedata.h in a bunch of places where it was implictly pulled in before - Fix dbg_toghidra() and ent_getedict() having mismatched return types between their headers and respective source files - Remove that one broken, hacky, secret Portal non-feature that probably nobody even ended up using; it can be implemented properly later if required
2023-05-05Implement APIs to control demo recordingMichael Smith
This is a surprise tool that will help us later!
2023-04-08Fix some miscellaneous stupid bugs and jankMichael Smith
Note: fixes.c was changed this year, so correct the copyright year too.
2023-01-15Fix a sizeof blunder I happened to notice recentlyMichael Smith
Nobody seems to have been affected by this in the wild yet, thank goodness. Will probably be a while before there's an actual release, so hopefully people will continue not to be affected. I suppose it's only an issue for paths longer than 128 characters, so it's not too likely to matter under normal circumstances...
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.
2022-08-10Add magical feature codegen system, at long lastMichael Smith
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.
2022-07-23Change some warnings to errorsMichael Smith
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
2022-05-31File a complaint about the error message 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.
2022-05-26Remove some dodgy whitespaceMichael Smith
2022-05-16Clean up some random bits and bobsMichael Smith
2022-05-16Make the demo directory check more robustMichael Smith
This is how it should've been to begin with, but I was lazy.
2022-05-04Fix a woopsy and slightly tweak autorecord UXMichael Smith
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.
2022-04-30Don't bump the demo number if playing another demoMichael Smith
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")
2022-04-24Reorganise and simplify demorecMichael Smith
- Demo recording can now be started before connecting to a server - The overall demo-number-preserving logic is a lot simpler and should work even if the plugin is reloaded or something - As an added feature, recording to a nonexistent directory will produce an error instead of silently failing
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.
2022-03-19Spruce up text and fix some copyright yearsMichael Smith
Sometimes, you just want to Unicode.
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.
2021-12-30Split up os.h, inline functions and fix some typosMichael Smith
2021-12-29Make convar init macro type-genericMichael Smith
This removes the need to call atof() on each cvar on plugin load; now all that's required is the memory allocations for the string values. The syntax is also a bit nicer since numbers can just be numbers rather than quoted strings. Minor issue: specifying a string value that also happens to be numeric will break this since the numeric representation will be zero, but I can't see a reason this would ever happen. Also, add a DEF_CVAR_MAX just for completeness.
2021-12-27Add custom demo packet stuffMichael Smith
This is more old code that wasn't part of the initial release. Figure I might as well throw it in for later.
2021-11-20Set sst_autorecord to 1 by defaultv0.1-BETAMichael Smith
A few of us agreed there's really no reason not to.
2021-11-20Initial public snapshotMichael Smith
With code from Bill. Thanks Bill!
