Hello! Im making an adventure map on "Creative mode",but im little bit scared,because when I finish the game,I dont know how I will get the game mode into "Survival"one.Can you tell me how to change modes? Because im full of ideas with my Adventure Map and I want to get that published so badly! Thank you for reading this!
If you get the 12w16a snapshot, you can type /gamemode 0 and you will be turned into survival. Other than that, you can download the TooManyItems (http://www.mediafire.com/?ez108xc2yye4k5q) mod which also allows you to obtain blocks you wouldn't normally get or Single Player Commands (http://www.mediafire.com/?3k066s9ip99ke0i) which puts 100+ commands into your single-player game, including one you can use to change your gamemode. (The links are the latest versions of the mod that I downloaded directly from the thread, then uploaded to mediafire. No viruses here!)
