Old



Old is a world type exclusive to the Pocket Edition. The purpose of this world type is for older or low-end devices that do not perform well with infinite worlds.

Creation
To create an Old world, simply select the "Old" type in the World Type dropdown of the world creation screen. Optionally, on low-end devices, toggle "Limited worlds" in the Video section of the options screen.

Structure
Old worlds consist of a finite map with an area of 256x256 blocks, barricaded with invisible bedrock. They can generate with any of the current biomes (excluding roofed forest); however, as a result of their limited size, only several biomes can be generated per world.

Structures, such as villages, generate normally, with the exception of caves, strongholds, and mineshafts. Tall grass does not grow in this world type.

In Old worlds, the Nether cannot be accessed unless the world is converted to the Infinite type, as detailed below.

Converting to Infinite
To convert an Old world to an Infinite type, tap on the pencil icon next to the old world in the world selection screen, then tap "Make Infinite!" This creates a new world with all of the saved data (inventory, terrain, structures, etc.) of the old world, sets the world type to Infinite, and keeps the world name; the old world is then renamed.
