Adventure

Adventure mode is a game mode intended for adventuring in which the player cannot place or destroy blocks, so as to avoid spoiling adventure maps by changing the map. It is likely that one would import and use custom adventure maps to be played, as a new map would not have much purpose or controllability, and a custom map would control certain aspects of the gameplay as well.

Once the player changes their game mode to adventure mode the player can no longer place or destroy blocks. The player can still interact with blocks that can be toggled, such as doors, levers, and buttons. The player can also still deal damage to mobs and trade with villagers.

In Adventure mode, the player cannot simply get resources by breaking items or by destroying or building blocks. The only way the player can get certain resources is by killing Mobs or trading with Villagers. However, depending on what type of an adventure it may be, many of these features are unnecessary, or often unavailable by conventional means. It may also be a way to cheat on a map that restricts the acquisition of specific objects.

Although it is impossible to destroy blocks manually, it remains possible to use an explosion to get some resources. However, this may ruin the aspect of gameplay by acting as a way to cheat a map, as well as an annoyance from creepers, and is likely to be controllable in the future. Explosions also can damage a map, rendering it unplayable or ruined.

Since it is impossible to place or destroy any block, it is useless to craft tools other than weapons (and shears to obtain wool, since some villagers will trade emeralds for it).

History
Adventure mode, formerly Dungeons and Levers, was announced by Notch on July 7, 2010. Notch hinted at for players to complete in Adventure mode. Adventure mode may include permadeath like in Hardcore mode, making it rogue-like in nature, and may have a quest system with randomly generated maps/quests.

The main reason for this game mode is so people can properly play adventure maps or mazes legitimately without the ability to break blocks to cheat. This will also be a game mode in multiplayer servers so certain players can be assigned it or for use with multiplayer adventure worlds.

Adventure Mode was officially added in Snapshot 12w22a, accessible through the cheats command, /gamemode 2 or /gamemode adventure. In snapshot 12w22a it is still possible to craft in adventure mode both with the 2x2 crafting grid in the player's inventory and with the full sized 3x3 crafting table. The player can still interact with blocks with an interface, such as chests, dispensers, crafting tables, furnaces and brewing stands. The player can also go through portals, but cannot activate one by using Flint & Steel; Flint & Steel can be used to activate TNT.
