Achievement

Achievements are a way to gradually guide new players into Minecraft and give them challenges to complete. Achievements were added to Minecraft on the 19th of April, 2011 in the 1.5 update.

Speaking to Gamasutra, 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. 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.”

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.

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:



Interface
Minecraft's achievement system involves a large tree comprised 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, and the test video posted by Notch. Among these are opening the inventory, mining wood and building a workbench.

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

Bugs

 * It is possible to simply throw a piece of leather on the ground and still earn the achievement for killing a cow.
 * If creepers blow up a tree and you collect the wood, or if someone on SMP tosses you a block of wood, you'll still get the "Getting Wood" achievement.
 * If you drop a piece of wood or simply pick up a piece of wood, you get the "Getting Wood" achievemnt.

Trivia

 * The first achievement confirmed by Notch was "When Pigs Fly", although it was more explained than named.
 * "The Lie" achievement is a reference to the promised cake in Portal that is eventually proven to be "a lie", and the Internet meme "The Cake is a Lie" that is of the same promised cake.
 * "On A Rail" is the name of a level in the original Half Life.
 * "Monster Hunter" is a reference to the video game Monster Hunter.
 * You can reset all of your Achievements by deleting the "stats" folder in the .minecraft app data folder. (WARNING: Also resets Statistics)
 * Completing achievements without their prerequisites will not count, despite the ability to do so legitimately.
 * There are no gold ores in the Achievements Menu background.
