My home setup is like this: We have 2 laptops connected wirelessly, 1 laptop connected wired, and 1 desktop connected wired. All are connected to the internet via a wireless router. What we want to do is be able to have the desktop computer "host" the Minecraft "server" and allow the other three laptops access it. Does anyone have instructions on how I set this up?
When you are in-game you can either use the
/publish command or use the "Open to LAN" button in the menu
To open your current single player world for other players in your LAN, type the command
/publishinto the chat (note that this is still very restricted, e.g. you can't adjust the game options using the commandline) or access the Game Menu and click on the "Open to LAN" button. There you can select the gamemode for other players and whether they should be allowed to use Cheats. Both of these methods give you an IP for use, for example: "Local game hosted on hostname:12345". If you type
/publishand want to change the default gamemode, type
/defaultgamemode 1for example. Note: two computers using the same Minecraft account name cannot connect with this method.
Now other players can either connect to your game using the link minecraft provided you or they can connect using the multiplayer menu with its new "Scanning for LAN-Worlds" section at the bottom.
Soruce: Multiplayer - Local area network
So to elaborate, on the Desktop Computer you would start up Minecraft, go into the world you're going to host and do what it says in the quote. the Laptops should then be able to use either the link you got or the Multiplayer Menu
In reply at the comment:
Ok so i started the LAN game on the Desktop computer and it tells me "Local game hosted on port 60715". But when i go to the laptop and startup minecraft (same version 1.8.4) and select Multiplayer game the Scanning for games on your local network just appears to be searching and not finding anything...
I've also had the same problem.
I solved the problem going to set the rules in the firewall.
Go into your firewall. "Windows Firewall" Then click the tab "Allow a program or feature through Windows Firewall" In here, scroll down to Java(TM) Platform SE binary. You may have 1 or more of them. Set all of them to public and then your friend will be able to join with your firewall still on. That's how I did it. Hope this helps.
