* Implement APIs to control demo recordingGravatar Michael Smith 2023-05-051-1/+60
| | | | This is a surprise tool that will help us later!
* Fix some miscellaneous stupid bugs and jankGravatar Michael Smith 2023-04-081-1/+1
| | | | Note: fixes.c was changed this year, so correct the copyright year too.
* Fix a sizeof blunder I happened to notice recentlyGravatar Michael Smith 2023-01-151-2/+2
| | | | | | | | | 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...
* Move towards C23, improve events and vcall macrosGravatar Michael Smith 2022-09-131-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Add magical feature codegen system, at long lastGravatar Michael Smith 2022-08-101-7/+7
|
* Split custom demo data into its own file/featureGravatar Michael Smith 2022-07-231-113/+1
| | | | Copyright note: the stuff Bill wrote is all still in the other file.
* Add keybind lookup codeGravatar Michael Smith 2022-07-231-11/+1
| | | | Also centralise NEXT_INSN macro, into its own header at least for now.
* Change some warnings to errorsGravatar Michael Smith 2022-07-231-2/+2
|
* Add alias management plus input filtering skeletonGravatar Michael Smith 2022-07-231-4/+4
| | | | | Some of the alias stuff was kind of stolen from earlier figuring-out Bill did. More Bill code is also on the way. :^)
* Solve the error logging situationGravatar Michael Smith 2022-06-021-27/+16
|
* File a complaint about the error message situationGravatar Michael Smith 2022-05-311-4/+6
|
* Add basic Portal crosshair colour customisationGravatar Michael Smith 2022-05-301-1/+1
| | | | | | | | | | | 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.
* Remove some dodgy whitespaceGravatar Michael Smith 2022-05-261-1/+1
|
* Clean up some random bits and bobsGravatar Michael Smith 2022-05-161-16/+4
|
* Make the demo directory check more robustGravatar Michael Smith 2022-05-161-4/+24
| | | | This is how it should've been to begin with, but I was lazy.
* Fix a woopsy and slightly tweak autorecord UXGravatar Michael Smith 2022-05-041-1/+7
|
* Add entity property finding and L4D warp testingGravatar Michael Smith 2022-05-031-1/+1
| | | | | | | | 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.
* Don't bump the demo number if playing another demoGravatar Michael Smith 2022-04-301-9/+9
|
* Centralise engine access, add Portal FOV changerGravatar Michael Smith 2022-04-301-16/+12
| | | | | | | | | | | | | | | - 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")
* Reorganise and simplify demorecGravatar Michael Smith 2022-04-241-145/+188
| | | | | | | | - 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
* Replace udis86 with a very small x86 decoderGravatar Michael Smith 2022-04-241-68/+44
| | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Spruce up text and fix some copyright yearsGravatar Michael Smith 2022-03-191-1/+1
| | | | Sometimes, you just want to Unicode.
* Tidy up stubs, make vstdlib a stub, build on LinuxGravatar Michael Smith 2022-01-061-3/+6
| | | | | | 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.
* Split up os.h, inline functions and fix some typosGravatar Michael Smith 2021-12-301-1/+1
|
* Make convar init macro type-genericGravatar Michael Smith 2021-12-291-2/+2
| | | | | | | | | | | | | 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.
* Add custom demo packet stuffGravatar Michael Smith 2021-12-271-5/+139
| | | | | This is more old code that wasn't part of the initial release. Figure I might as well throw it in for later.
* Set sst_autorecord to 1 by defaultv0.1-BETAGravatar Michael Smith 2021-11-201-1/+1
| | | | A few of us agreed there's really no reason not to.
* Initial public snapshotGravatar Michael Smith 2021-11-201-0/+218
With code from Bill. Thanks Bill!
