Overview of an Old world

Old was a Minecraft:world type exclusive to Template:El and Template:El. The purpose of this world type was to provide smaller worlds on older or low-end devices that did not perform well with infinite worlds.

Creation

To create an Old world, all the player had to do was select the "Old" type in the World Type drop-down of the world creation screen. Optionally, on low-end devices, the player could toggle "Limited worlds" in the Video section of the options screen. This sometimes failed due to limited access.Template:Only

Structure

Overworld

Old worlds consisted of a finite map with an area of 256×256 blocks with 128 maximum block height, but could be expanded in area using a NBT editor by changing the Template:Cd and Template:Cd values.

Biomes that could not be generated in this world type:

• Template:BiomeLink
• Template:BiomeLink

However, as a result of their limited size, only a few biomes could be generated per world. In addition, since dark forests did not generate, areas of specific lush biomes were shuffled slightly, compared to their placements in default worlds. Also, biomes that were generated here were shrunken 4× (16× area) to allow more biomes to generate. Due to this shrinking, a seed generated different terrain in an old world than in an infinite world, although with similar overall characteristics (for example, the "Island Survival" seed from Minecraft:seed templates put the player on an island in the middle of the world, but the resemblance ended there).

When creating an Old world, the Minecraft:player always spawned in the middle of the world. If the starter map was enabled, the map was in scale level Template:Frac rather than of Template:Frac. Additionally, the player respawn radius during world creation or world edit could be up to 256 blocks, rather than up to 128 blocks as in Minecraft:flat and infinite.

The center of the world was rarely at 0,0, meaning the game found a valid spawn point, then it limited the world to 256×256 around that point, so the center of the world was the coordinate of that spawn point. It was possible, through NBT editing, to move the center of an old-world to another area in the seed.

Some generated structures never appeared in the Old world type:

• Minecraft:Mineshafts, Minecraft:ocean monuments, Minecraft:woodland mansions, Minecraft:strongholds, Minecraft:dungeons, Minecraft:desert pyramids, Minecraft:jungle pyramids, Minecraft:swamp huts, Minecraft:igloos, Minecraft:ocean ruins, Minecraft:shipwrecks, Minecraft:pillager outposts, and Minecraft:ruined portals did not generate, making resources limited.
• Minecraft:Caves and Minecraft:canyons did not generate in this world type, making the underground area solid, although Minecraft:amethyst geodes and other hollow areas occasionally appear.
• Tall grass and ferns did not generate as part of any biomes, though they could generate as part of village structures. This made certain biomes such as plains and savannas less grassy. Grass only generated in Minecraft:bamboo jungles, while large ferns were generated normally.
• Even with experimental gameplay enabled, the world height was 128 blocks, with the bottom layer at Y=0.

Other structures could generate in the Overworld:

• With this world type, the Overworld was the only dimension that generated. Attempting to go to other dimensions resulted in the portal not being activated.
• Minecraft:Villages sometimes generated near the world border and get cut off by it, resulting in a village without any meeting point, only one house, or a jobsite building, or even just a road.
• Lakes could still generate normally, but lava lakes did not generate near bedrock. Also, lakes did not generate under Y=10, due to the ground being completely solid.
• Minecraft:Desert wells rarely generated in this world type.
• On rare occasions, Minecraft:buried treasure and Minecraft:fossils could generate.
• New Minecraft:Mountains still generated with experimental gameplay enabled, but were cut off at Y=127, causing the top of them to become a flat plateau of stone. This usually happened if mountains generated past the meadow layer.

Some mechanics broke in this world type:

• Unlocking the last tier of cartographer Minecraft:villagers caused the game to stop ticking.
• If the player obtained an ocean explorer map or a treasure map from commands, any explored areas outside the world border were completely black. If the player attempted to get a woodland explorer map, the game stopped ticking for about 100 seconds, and an error message was eventually given.
• Feeding a dolphin caused it to try to swim outside the world border.

Due to the structure limitations in this world type, many resources became unobtainable in survival, and some mobs could not spawn naturally.

Because of that, playing survival in this world type was challenging, due to the structure limitations reducing resources and also affecting mob spawning. While water and lava always generated in this world type, lava usually did not on the surface, although it always did underground and always directly in contact with the invisible bedrock in extremely small patches of 1×1 block. If the Overworld didn't generate lava, then cobblestone would become non-renewable without going to the Nether.

Nether and End

In Old worlds, Minecraft:the Nether and Minecraft:the End could not be accessed unless the world was converted to the Infinite type, as detailed below.

However, the Nether and the End actually existed in this world type but the only way to access these dimensions was via command Template:Command, Template:Command, or Template:Command with the corresponding portal, just like the Minecraft:Overworld.

Both the Nether and the End were also bordered with the size 256×128×256. The Nether still generated normally, but the 8:1 travel ratio was maintained, meaning that returning to the Overworld often caused the player to become stuck (due to the Overworld being 256×128×256 in size).

If a Minecraft:nether fortress was generated, it was most likely going to be cut down by the world border. Despite Minecraft:nether portals not being able to be activated, returning from the Nether to the Overworld caused a newly activated Nether portal to generate in the Overworld (this is due to nether portals not counting when placed with commands).

The End in Old worlds generated only the central island without the outer islands. Sometimes the Minecraft:exit portal did not generate and the Minecraft:ender dragon sometimes got stuck at the border. Minecraft:End gateways also did not work, due to the size limit.

Converting to infinite

To convert an Old world to an Infinite type, all the player had to do was to select the pencil icon next to the old world in the world selection screen, and then selected "Make Infinite!". This created a new world with all of the saved data (Minecraft:inventory, terrain, structures, etc.) of the old world, set the world type to Infinite, and kept the world name; the old world is then renamed <WorldName>-Old.

After converting to Infinite, the terrain copied from the old world had a chunk border separating it from the added area, as infinite worlds generate larger biomes.

This process is not available in Minecraft:China Edition.
