When a map is created randomly, how can we find the seed that it has generated ?
I want to find some cool map in single player and when I’ll find one, I want to get that seed and create it on my SMP server.
Answer
In 1.3 and above you can type /seed into the console to view it.
However, this is not as good because usually you want the world seed to create another world like it, to share with a friend, and you can’t copy/paste it.
For pre-1.3 versions (and for if you want easy copy/paste) go to seedscope.net, then upload your level.dat file, and it will show you your seed.
