Achievement

Achievements are a way to gradually guide new players into Minecraft and give them challenges to complete.

In an interview by Gamasutra before February 25, 2011, Notch said: “I like achievements. I know a lot of people don't, but I like them. I've had the idea to make achievements kind of like the in-game questing. So you'd be able to see the first achievement in a tree of achievements, and you unlock the top ones first before you can unlock the ones further down."

He also said: “So the first one might be to chop down a tree, or kill a chicken, and then these branch into more things you can do. Hopefully it would encourage people to try new areas. It could converge into a big task, like kill a dragon or something, which would put a kind of narrative into the achievement tree.”

Finally, asked if such a move would risk leading players down a preset path, rather than encouraging exploration and invention as Minecraft does in its current state, Notch said: “Definitely not. I’d want these achievements to feel like things you can try, rather than these are things you have to do. People can follow them, but only if they want to.”

Achievements can be completed in any game mode, including Creative.

Notes


 * For achievements which may be obtained by picking up items, transferring an item from a chest to your inventory does not qualify; you must throw the item on the ground first.

Interface
Minecraft's achievement system involves a tree composed of achievements, some of which must be completed before others can be. Originally the interface showed the achievement tree on the left, and a 'mini-map' of the tree on the right. The mini-map was removed in the final version, which now simply shows the tree. The background of the tree mimics the world with sand at the top with dirt spanning below, bedrock at the bottom, and ores distributed as they would be in the world.

Test achievements can also be found within Minecraft Beta 1.4's source code before the 1.5 release, and on the test video posted by Notch. Among these are opening the inventory, mining wood and building a workbench.

History
Achievements were added to Minecraft on the 19th of April, 2011 in the Beta 1.5 update.

The first achievement confirmed by Notch was "When Pigs Fly", although it was more explained than named.

The Beta 1.4 update was originally intended to include achievements and statistics; However, implementation was pulled from the release because it was not yet functional. It was implemented into Beta 1.5 instead.

Prior to Beta 1.9 pre-release 6, the image used by "The End." was that of a Monster Spawner; this was because the Dragon Egg was not implemented at that point. This was changed upon its addition.

As of 1.0.0, there are exactly 27 achievements.

March 18th Update
On March 18th, Notch talked about Achievements and Statistics on his Blog. He said the following:



Also, he added that Achievements will not be chores:



Preview Video
On April 8, 2011, a video was uploaded to YouTube showing weather, statistics and achievements.

Bugs

 * The achievement "Overkill" actually requires to deal nine (and not eight) hearts of damage in a single hit (verified from source code).
 * Statistics and achievements sometimes reset for no reason at all.
 * Statistics and achievements reset when you update your Minecraft.jar such as adding or deleting mods.
 * a specific mod will allow you to unlock all achievements just by clicking on them.

Trivia

 * The achievement "Acquire Hardware" might be a reference to Half-Life 2. In Half-Life 2, there is an achievement called "Trusty Hardware", which is awarded when the player picks up the crowbar.
 * "The Lie" achievement is a reference to the promised cake in the game Portal that is thought to be "a lie", and the Internet meme "The Cake is a Lie" that is of the same promised cake.
 * Another reference to Valve's games is an achievement name "On A Rail", which is the title of one of the chapters in Half-Life.
 * You can reset all of your Achievements by deleting the "stats" folder in the .minecraft app data folder. Beware that it also resets Statistics.
 * Completing achievements without their prerequisites will not count, despite the ability to do so legitimately.
 * There are neither Gold Ores nor Lapis Lazuli ores in the Achievements Menu background.
 * "Achievement Get!" is not just a grammatical mistake, but a deliberate reference to a decade-old proto-meme. Early screenshots of Super Mario Sunshine used the Japanese localization, and featured Mario grabbing a "Shine" item with the prominent text "Shine Get!". Due to the prominence of the game and the attention given to these screenshots, "[noun] Get!" subsequently became a popular term used on image boards as post count benchmarks, which Notch occasionally visits.
 * If you have a texture pack that edits item/block textures, they will show up in the achievement screen as those textures.
 * An "Overkill" is "the use of excessive force or action that goes further than is necessary to achieve its goal, most commonly in acts of violence".
 * "We Need To Go Deeper" is a reference to the movie Inception.
 * "Return to Sender" refers to a message often written on non-personal letters, usually in case that a letter ends up at an incorrect address. (There is also an Elvis song with the same title)
 * A "Local Brewery" is a local place where beer or other spirits are brewed.
 * You can actually complete "We Need To Go Deeper" without mining with diamond tools or going deeper than diamond level.
 * If you set your language to "Pirate Speak", "The Lie" achievement will be named as "Pirates Don' Get Portal Referances".
