Question: how to play multiplayer in minecraft tlauncher lan?
Answer: Now open TLauncher, choose the version with the TL icon and run the game (it is better to login to the TLauncher.org account). If you select the version without TL icon, you will not be able to connect to the server without a Mojang license. Go to your world and in the Pause menu (Esc) click Open to LAN.
