This README is for those looking to work on the code. For actual plugin +documentation, you'll want to look at the website, which doesn't exist yet, +or ask for help in the relevant speedrunning Discord, which does exist yet. + +NOTE: Please read and understand LICENCE before redistributing this software! + +== Compiling == + +Windows: + - Install the Windows 10 SDK via the Visual Studio Installer. + - Install native Clang from https://clang.llvm.org (NOT MinGW/MSYS2 Clang!). + - Run compile.bat (in lieu of a better build tool, to be figured out later). + +Linux: + - Install Clang (and LLD) via your system package manager. Technically, GCC + might be able to compile this too, but Clang is heavily preferred in the name + of consistency and using GCC will require a decent amount of fiddling. It's + also not tested and might break and I probably won't care that much. + - Install 32-bit C libraries and the C library headers if they're not already + installed. + - Run ./compile (in lieu of a better build tool, to be figured out later). + +* NOTE: Linux builds currently fail; there's a bunch of code that needs to be + written. See also TODO/linux. + +== How and where to install == + +Very old Source builds load plugins from the top-level bin/ folder, while +relatively modern builds load them from the mod-specific directory, e.g. +left4dead2/, hl2/. Since this plugin is designed to be universal, the +recommended practice is to put it in bin/ regardless and then use the command +`plugin_load ../bin/sst`. The way the paths work out, that ends up always +working no matter what, and allows the plugin to be shared between different +mods in the same engine installation where relevant. It's also possible to just +back out of the game installation with ../ and load from whatever directory you +want, as long as it's not on a different Windows drive letter. In that case, the +plugin can be shared between multiple games. That said, it's a little more +annoying to do and a little less self contained. + +IMPORTANT: If your game supports multiplayer, always launch with -insecure as a +launch option before loading this plugin! In theory, plugins shouldn't be able +to load without this, or it should at least be impossible to connect to a VAC- +enabled server with the plugin loaded, but -insecure is the safest way to ensure +VAC is completely disabled, otherwise you use the plugin AT YOUR OWN RISK OF +BEING BANNED! + +Note: some very old (and very new) Source builds don't have a plugin_load +command. It may be possible (although questionably necessary) to support these +games with an injector to forcibly load the library into the game. For the time +being, however, these versions are unsupported. diff --git a/TODO/autocomplete b/TODO/autocomplete new file mode 100644 index 0000000..cc3e867 --- /dev/null +++ b/TODO/autocomplete @@ -0,0 +1,4 @@ +Console command autocompletion +==== +This isn't really something we need right now, but is worth documenting in case +we deem it useful later. diff --git a/TODO/autojump b/TODO/autojump new file mode 100644 index 0000000..7b9c8b4 --- /dev/null +++ b/TODO/autojump @@ -0,0 +1,5 @@ +Add back autojump +==== +I already wrote (and rewrote) the code long ago, but it's a secret until we +further raise the verification standard for L4D2.
