for me and my sister, she wants to do an adventure map with me but we have no server and I've tried over and over again to make one but I is hopeless...
3: could someone either make a server me and my sister can use or help me a little to make one?
It is actually very simple to make one.
1. Download the most recent version of the server software from Minecraft,net, and have the newest version via force update on your client.
2. Put the server in a completely empty folder.
3. Run the server, and then type in stop to stop it.
4. Go to "search" on your computer and type in "cmd" and click on the only thing that pops up
5. type in ipconfig into cmd to find out your ip. Use the external one.
6. Considering it is your sister, you probably share the same ip. change server.properties into a .txt and make the server ip the same as your external ip.
7. change it back to a .properties file and start the server. typing in the set server ip into your minecraft should connect you.
note: both of you need purchased minecraft accounts to connect to your server.
Note #2: a bukkit server is a bit different and I reccomend going to a Youtube video for that.
