Well it's actually because it stands for "Remote procedure call"
Major thanks to axolotl for creating the original mod and allowing me to recreate it in BepInEx. Another major thanks to Glom for his amazing LLBML library which makes development a breeze.
A few notes: This mod sends third party data to https://blazelb.xyz. The data in question is:
This mod also copies a file into the games root directory. "discord_game_sdk.dll" which is a library to integrate Discord Rich Presence.
Right click a friend to invite them. You can also invite directly from a channel, either by right clicking a player and inviting them there, or by using the plus icon next to the chatbox.
Some problems with the LLBMM mod has been fixed, namely how steam opened Discord instead of LLB when starting the mod, thus making steam think that Discord is LLB, stopping the game from launching.
The "Ask to join" button directly in a users rich presence does not work, this is a problem with the Discord Game SDK and there isn't anything i can do about it at this point. The "Ask for invite" button when right clicking a user will send the request twice.
If after installing, rich presence does not work. Check the LLB root folder for a discord_game_sdk.dll. If it isn't present, manually copy the discord_game_sdk file from the BlazeDiscordRPC folder and place it in LLBs root folder and rename it discord_game_sdk.dll
