#This script requires the following packages to work
#screen, rainbowstream (can be installed with pip3), nmap, bash
#
##Must have rainbowstream already SET UP see https://www.tecmint.com/rainbow-stream-command-line-twitter-client-linux/
#
##CONFIGURATION, defaults only work for one local MC server running on port 25565
#This is the address to connect to server ex. hypixel.net
address=p.zuligen.com
#port number for the minecraft server
port=25565
#name of screen session to create (for running rainbowstream) use that if you are planning to set up more than one server monitor on one device
#DO NOT USE SPACES
screenname=rbowstream
#Text before number of players and time statement
textbefore="There are"
#Script uses nmap to detect if players are/ online for a minecraft server
#start up rainbowstream
##DO NOT EDIT BEYOND THIS POINT UNLESS YOU KNOW WHAT YOU ARE DOING
