Requirements

Client

• Minecraft v1.16.5
• Minecraft Forge for v1.16.5

Server

Minecraft

Note: This mod will modify the world it is loaded on. It is recommended to only use it on a new world.

• Minecraft server running v1.16.5 (tested only on Vanilla / MSM)
• Minecraft Forge for v1.16.5
• Codslap! mod (https://www.curseforge.com/minecraft/mc-mods/codslap)
• Server access to either run additional processes on the server, or open additional TCP ports

NodeJS

• NodeJS v14.16+
• Optional: Yarn v1.x (Yarn Classic)

Client

• Install the MinecraftForge mod loader: https://files.minecraftforge.net/net/minecraftforge/forge/
• It should create a profile for itself in your Minecraft launcher
• In the Minecraft launcher, click the "Installations" tab at the top
• Click the folder icon for the "forge" installation. This should open the installation folder.
• Download the Codslap! mod (https://www.curseforge.com/minecraft/mc-mods/codslap) and copy the .jar file into the mods folder located in the installation folder

Server

Minecraft

• To install MinecraftForge, download and run the installer on a new server: https://files.minecraftforge.net/net/minecraftforge/forge/
  • See https://blog.za3k.com/running-a-forge-server-on-headless-linux/ for additional installation instructions
• Download the Codslap! mod (https://www.curseforge.com/minecraft/mc-mods/codslap) and copy the .jar file into the mods directory located in the server directory
• Start the server normally once the mod's .jar file is copied
• If the NodeJS server will be run on a different machine than the Minecraft server, ensure your network configuration allows port 8888 to be routed to the Minecraft server

NodeJS

• Clone this repository in a separate directory on the same machine as the Minecraft server, or on a machine that has network access to port 8888 on the Minecraft server
• In the cloned repository directory, run yarn or npm install

Running NodeJS and Minecraft servers on the same machine

Run yarn start or npm run start

Running NodeJS and Minecraft servers on different machines

Run yarn start --host HOSTNAME or npm run start --host HOSTNAME

HOSTNAME can be the IP address or FQDN for the Minecraft server.

Example:

# FQDN
yarn start --host my-awesome-minecraft-server.some-domain.com

# IP Address
yarn start --host 192.168.1.2

Usage

Once both the Minecraft and NodeJS servers are running, operators can initiate minigames using the in-game commands:

• minigame list - lists available minigames
• minigame start [minigame_name] - starts the specified minigame
• minigame stop [minigame_name] - stops the specified minigame - all scores are deleted
• minigame reset [minigame_name] - resets a game in progress

For now, only one minigame is available:

minigame start codslap

Once the game is started, all players will be moved to a "holding area" while the minigame arenas are generated. Players will be moved to the arena, and the game will progress automatically.

Troubleshooting

If the minigame appears to stop working - Codslaps are no longer being counted, or it is not switching arenas in a reasonable amount of time, the NodeJS server may need to be restarted. Quit the NodeJS process by hitting CTRL+C twice, and start it again.
