Thank you all for taking the time to read this thread! I just need help with a couple of things. First: I need all the /play commands for all the games that /play works with for a mod kinda like this: https://hypixel.net/threads/quickmode-a-simple-minecraft-mod-for-hypixel-typers.1945529/ Second: I need some way to sense a message in chat, such as "aRandomPlayer entered the world," for a housing mod request. The mod will sense the enter message and then it will say "Welcome, aRandomPlayer!" like that. The second time they join, it will say "Wlc back, aRandomPlayer!" somehow with another file on your computer.
