2023-05-01Argh, bump the stupid copyright header!Michael Smith
I need to write a pre-commit hook to check this or something.
2023-04-28Fix default float values for cvarsMichael Smith
This has been a known issue for a long time. Let's finally fix it!
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.
2022-05-16Clean up some random bits and bobsMichael Smith
2022-05-12Further clean up engine API initialisationMichael 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")
2022-04-26Fix a couple of bits of convar min/max brokennessMichael Smith
It's amazing how long these things can go unnoticed.
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.
2022-03-20Support deferring cvar registrationMichael Smith
This allows stuff to be registered conditionally. Unfortunately cmeta is now truly the worst thing of all time, but cleaning it up isn't a huge priority. On the plus side, codegen actually got simpler.
2022-03-19Spruce up text and fix some copyright yearsMichael Smith
Sometimes, you just want to Unicode.
2022-01-18Very slightly tidy RTTI stuffMichael Smith
More handwavey Linux prep, nothing too significant.
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.
2021-12-29Make 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.
2021-12-26Unhide 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!
