This question is regarding the minecraft Beta 1.8 prerelease -- I have a beautiful house in single player survival which I'd like to record while flying.
I want to be able to change the game mode of my survival map to creative to be able to fly through it without installing a mod. I know it is possible if you run the map on a multiplayer server via the command
/gamemode <user> 0|1 but I want to achieve this in single player :)
I think this would be possible through editing your level.dat file as I think that's where the game mode for the map is stored.
