Realms



Minecraft Realms, also known as Realms, were added in and is a work-in-progress feature that allows for paid public servers hosted by Mojang. Realms provide an easy and faster way to create Minecraft servers and allows more control for the creator. Minecraft Realms are not intended for large public servers but for groups of friends or as a family server.

Minecraft Realms have been in development since Minecon 2012, when Mojang revealed that they wanted to host their own servers.

About 100 players were selected by a computer algorithm to test the first publicly released version of Realms. However, only active accounts were chosen among the random algorithm.

The chosen players can create their own Minecraft worlds, and is optimized to allow up to 10 people into the world, whether or not they were originally chosen to test. Only one server can be made at a time if hosting. Players that are invited will have the Realms option appear on the screen, which then the invited players can enter and explore the world they were invited in.

Minecraft Realms will be hosted by Multiplay Gameservers on the PC and via Amazon for Minecraft Pocket Edition

Subscriptions


Minecraft Realms are not free. Rather, players have to subscribe to use the feature. The 100 beta testers have a subscription which lasts for 90 days. By viewing the language files in Minecraft via an editor, these lines can be seen:

Settings


If you are one of the 100 beta testers, or have been invited to join a realm by a beta tester, you will see a Minecraft Realms button on the main menu screen. The "Minecraft Realms" button is in the same place as the "Texture Packs" button (removed earlier in ). Clicking on it brings you to the screen above. The screen is very similar to that of the Multiplayer menu, with a few differences.



Clicking on "Configure" brings you to the configuration menu. To the left, you have the Name and Description. To the right, you have a list of all the invited players.

URL's that were found trought the Minecraft Realms package): https://mcoapi.minecraft.net/ https://mcoapi.minecraft.net/worlds/$ID https://mcoapi.minecraft.net/worlds/$ID/join https://mcoapi.minecraft.net/worlds/$NAME https://mcoapi.minecraft.net/worlds/$NAME/$LOCATION_ID https://mcoapi.minecraft.net/mco/available https://mcoapi.minecraft.net/payments/unused https://mcoapi.minecraft.net/worlds/$WORLD_ID https://mcoapi.minecraft.net/worlds/$WORLD_ID/invites/$USER_NAME https://mcoapi.minecraft.net/worlds/$WORLD_ID/$NAME https://mcoapi.minecraft.net/worlds/$WORLD_ID/open https://mcoapi.minecraft.net/worlds/$WORLD_ID/close https://mcoapi.minecraft.net/worlds/$WORLD_ID/reset https://mcoapi.minecraft.net/worlds/locations https://mcoapi.minecraft.net/subscriptions/$WORLD_ID
