As the title says, this is a mod that adds multiplayer to the virtual reality game Hotdogs, Horseshoes and Hangrenades.
So you should end up with a H3VR\BepInEx\plugins\H3MP folder, containing H3MP.dll and other files.
Can be done through thunderstore using r2modman mod manager
All H3MP functions can be access through the wristmenu, in-game (apart from the settings in the config file, see Config section below).
To join a server, you will have to have set the IP and port of the server in your config file (see Config section below), then, in the wristmenu, press H3MP->Join
If you forgot to set these before going in-game and restarting the game is too much of a hassle, mainly for people with 200+ mods that I figured probably take a while to load, you can set your config, then go to H3MP->Options->Reload config in the wristmenu which will reload your configs, after which you can connect/host
In the wristmenu, some options are available:
Reload config: Will reload the config file if you modified it since starting the game. Useful if you modified it and don't want to have to restart the game.
Item interpolate: This will toggle item interpolation. Item interpolation is the smoothing of item movement to prevent everything from looking "jagged". Turning it off will ensure that items are positionned/rotated exactly as you receive the data from another client. Due to latency, this will make item movement look extremely low FPS.
The config refers to a file in the H3MP folder called Config.json which contains a few important settings.
To host a server on a local network, you can set your IP as your machine's local IP address, which can be found by running the "ipconfig" command in CMD.
To host a server for public access, you will need to set your IP as your machine's public IP address, which can be found by searching "what is my IP" on google. For public access, you will need to port foward the port you have set in your config.
To start the server, in the wristmenu, press H3MP->Host
