Unfortunately, you can not change your name on Minecraft!
The only way to get a command block in Minecraft is to have cheats on in your world.Once you generated a world like that, type in the following command:/give [your Minecraft character's name] 137 [amount up to 64]That will give you a command block.
If you mean Minecraft Classic, this is not possible. Minecraft classic is only meant for building, not survival. If you want to have survival, you'd have to buy the full version. To change day to night in Minecraft premium (full), as of 1.3 the command prompt was added to single-player so issue the command /time set night.
It must have the factions plugin. The command it /f create name
It is /time set [time] Replace [time] with: 0 for Day 14000 for Night
You go to the command, Type in Spawn, space, then the creature name, id, random.
There is no command block in minecraft. If you go to the Minecraft WiKi it will have all the information you need for anything in the game.
Put it in a anvil
A friend system is not built into the Minecraft game. Some servers have a friend system, the command is usually /friend add <name>
the command block doesn't have an ip.
On a vanilla server you can use the command /toggledownfall This will, as the name states, will either stop or start snow or rain. On a bukkit server you can install a plugin called essentials that will allow you to set the global weather to whatever you choose. The command for this is /weather <rain, sun, snow>
If you're using WorldEdit. The command is, /tree redwood
Only they can change their own name, unless you are the admin of the server (in which case you can use the "name" command on their console).
yes
By either going into creative mode and getting a Spawn Egg, or by activating "Cheats" in Survival mode and using the command "/give (Minecraft Name) (Number) (ID Number for Spawn Egg/Name of Spawn Egg)"
The command is /timeset day. This can only be used by admins and ops.
You type a command into them, then activate it like any other redstone item
