README
# metamod-fallguys This is a modified version of metamod along with a group of metamod plugins mainly to provide server-side feature expansions for Sven Co-op. This metamod is based on [Bots-United's metamod-p](https://github.com/Bots-United/metamod-p) * Any third-party plugins such as [amxmodx](https://github.com/alliedmodders/amxmodx) are still compatible with this modified version of metamod. * You are welcome to request for any new hooks or server-side features which is not implemented by Sven Co-op team yet. * Compatibility with other games (e.g. Counter-Strike) is not guaranteed as it's designed only for Sven Co-op. ## The differences between this metamod and Bots-United's one ? 1. An older version of glibc (iirc it's 2.24, which is literally the glibc that linux build of Sven Co-op is using) is forced to be used in the makefile. The compiled binaries (`.so`) are portable now. No need to recompile them when running on an up-to-date linux distribution. 2. A fallback solution was added to mitigate a problem that `GiveFnptrsToDll` could not be found in plugin dll (This used to happen when plugin was compiled by a newer version of Visual Studio like VS2022). see also https://github.com/Bots-United/metamod-p/issues/24 3. A couple of new APIs were added to mutil API set. ## Related project [Fall Guys in Sven Co-op](https://github.com/hzqst/sven-fallguys) [Physics vehicle demo in Sven Co-op](https://github.com/hzqst/sven-vehicle) # Plugins ### fallguys.dll (fallguys.so) * This is required by map `Fall Guys in Sven Co-op` [Documentation](docs/README_FALLGUYS.md) ### asext.dll (asext.so) This plugin provides ability of registering third-party hooks or methods in Sven Co-op's AngelScript engine. * This is required by map `Fall Guys in Sven Co-op` [Documentation](docs/README_ASEXT.md) ### ascurl.dll (ascurl.so) This plugin provides ability of using libcurl to send HTTP request in angelscript. mainly for server ops and developers to use in their own angelscript plugin. * This is not required if you just gonna play `Fall Guys in Sven Co-op` [Documentation](docs/README_ASCURL.md) ### asqcvar.dll (asqcvar.so) This plugin provides ability of retreiving cvars from client. mainly for server ops and developers to use in their own angelscript plugin. * This is not required if you just gonna play `Fall Guys in Sven Co-op` [Documentation](docs/README_ASQCVAR.md) ### asusermsg.dll (asusermsg.so) This plugin provides ability of hooking UserMsg. mainly for server ops and developers to use in their own angelscript plugin. * This is not required if you just gonna play `Fall Guys in Sven Co-op` [Documentation](docs/README_ASUSERMSG.md) # Installation tutorial video: https://www.youtube.com/watch?v=r2NRp5TZmUM 1. Download latest build (-windows or -linux depending on your OS) from [GitHub Release](https://github.com/hzqst/metamod-fallguys/releases), then unzip it. 2. Copy everything from the previously unarchived `build` directory into `\steamapps\common\Sven Co-op\svencoop` * (Warning: neither `svencoop_addon` nor `svencoop_downloads` is supported)* * The directory hierarchy should be something like this : ``` Sven Co-op/ (or Sven Co-op Dedicated Server/) |-- svencoop/ | `-- addons/ | `-- metamod/ | |-- dlls/ | | |-- asqcvar.dll (asqcvar.so) | | |-- ascurl.dll (ascurl.so) | | |-- asusermsg.dll (asusermsg.so) | | |-- asext.dll (asext.so) | | `-- fallguys.dll (fallguys.so) | `-- plugins.ini |-- svencoop_addons/ |-- svencoop_downloads/ `-- svencoop.exe (or svends.exe / svends_run.sh / svencoop.sh) ``` 3. If you had installed metamod and metamod plugins from other sources such as [Bots-United's metamod-p](https://github.com/Bots-United/metamod-p) or [jkivilin's metamod-p](https://github.com/jkivilin/metamod-p), you will have to add those metamod plugins back to `plugins.ini` which might have been overwritten in the step (1). 4. You should either * Add `-dll addons/metamod/dlls/metamod.dll` (Windows) or `-dll addons/metamod/dlls/metamod.so` (linux) to launch parameter. or * Edit `Sven Co-op/svencoop/liblist.gam`, and change: ``` gamedll "dlls/server.dll" gamedll_linux "dlls/server.so" ``` to ``` gamedll "addons/metamod/dlls/metamod.dll" gamedll_linux "addons/metamod/dlls/metamod.so" ``` to make metamod work. The edited `liblist.gam` should be something like this  * `addons` must be installed into `/Sven Co-op/svencoop`, neither `/Sven Co-op/svencoop_addons` nor `/Sven Co-op/svencoop_download` * All plugins from this repository are not binary-compatible with `metamod-p` from other sources. You should always use metamod from [metamod-fallguys](https://github.com/hzqst/metamod-fallguys/tree/main/metamod) to load those plugins. * Other third-party plugins ( e.g [amxmodx](https://github.com/alliedmodders/amxmodx) ) are still binary-compatible with [metamod-fallguys](https://github.com/hzqst/metamod-fallguys/tree/main/metamod). You don't have to re-compile them. Just put them in the `plugins.ini`. # Build Requirements (Windows) 1.
