This is the source code for the Discord bot and Among Us client that compromise Impostor. Note that Impostor is not intended for self-hosting (although it is theoretically possible), so if you want Impostor on your Discord server the easiest solution is to simply click here.

This project consists of two components, creatively named bot and client. Bot is the Discord part written in TypeScript that handles all the logic around command handling, session management, member voice channel moving, etc. Client is a simple C# implementation of the Among Us networking protocol, just barely enough to connect to the lobby, fetch player data and emit events. Bot launches a client instance for every lobby, reading events from client through stdout.

To get started with developing the bot, you'll need to install dependencies. First of all you need to have Node.js installed. After that, simply run npm/yarn install to get all the dependencies needed.

./node_modules/.bin/tsc -w will start a watching TypeScript compiler that will automatically compile the TypeScript source to JavaScript. After that, simply configure your .env by copying the template and filling in values, then run node dist/index.js to start the bot.

Note that you will also need a PostgreSQL database for running the bot.

For the client, be sure to clone the repository with submodules enabled, then simply open the solution in client/ to develop. You can also use the dotnet CLI to build the client, using dotnet build.

0. Install Node.js + npm, .NET Core, PostgreSQL, and any others needed.
1. Clone the repository recursively (git clone --recursive https://github.com/molenzwiebel/Impostor)
2. Navigate to .env.template, duplicate the file, rename to .env, and fill in the blanks. The result will look something like this:

DISCORD_TOKEN=<your token here>
AU_CLIENT_DIR=../client/bin/Debug/netcoreapp3.1
DATABASE_URL=postgresql://postgres:<your password here>@localhost:5432/postgres

3. Update the code associated with the emojis in bot/src/constants.ts (add the ID, name, etc)
4. Navigate to /bot in your cmd/PowerShell/terminal
5. Run npm install to install dependencies.
6. Run ./node_modules/.bin/tsc to compile TypeScript to JavaScript.
7. Run node dist/index.js (pm2 is recommended to keep it running for long periods)
8. Change directory to /client
9. Open cmd/PowerShell/terminal and run dotnet build

Note: When using Linux, I recommend setting up a .sh file to simplify the process when rebooting the bot, as some bugs in the code require a restart.
