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 dirt at the top, 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.

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 cake in Portal, and the Internet meme "The Cake is a Lie".
 * "On A Rail" is the name of a level in the original Half Life.
 * The achievements are linked, requiring you to do something before it is even possible to complete the next. However, the achievement 'When Pigs Fly' requires a saddle, which is linked to Cow Tipper, in which requires the harvest of leather. This is a possible reference that saddles could be crafted in the future using leather.
