Additions

Gameplay

  • Blocks cannot be placed past the existing border.

  • Added a flashing white overlay that displays on the side of a block that the player has their mouse over.

Changes

World generation

General

• Level generation improved to be not so messy and random, as shown in the Minecraft:Cave game tech test video, but instead completely flat, similarly to a modern Minecraft:superflat world.
• Blocks generate from Y=0 to Y=43, below Y=0 is essentially the void.
• Visually, Y=43 is always Minecraft:grass blocks, with all other blocks being Minecraft:stone.

Removals

World generation

Minecraft:Caves

• No longer generate.

Bugs

3 bugs reported

• Minecraft:Blocks can be placed directly within the space occupied by the player.<ref>TigIRC logs: "(14:10:09) Zaratustra: I can spawn blocks where I currently exist" [...] "(14:10:32) notch: yeah, it's one of those bugs.. I keep ignoring it" (18:10 UTC, May 16, 2009)</ref> This bug remained in the game until Minecraft:Classic 0.0.9a.
• Some players experience extreme levels of lag, commonly on Intel GPUs, when getting close to the ground after booting up the game, making it completely unplayable with an FPS of 1. The FPS may become moderately playable and somewhat smoother when the player builds up at least 3 blocks.<ref group="note">This fix varies across different computers, as sometimes it gets bypassed entirely, and sometimes it does not work.<ref>Template:Cite</ref> A tutorial on how to fix this can be found here.</ref>
• The camera pivot bug causes the view to rotate around a fixed point in the world instead of rotating on the player's axis. This causes the player's perspective to physically shift when looking around.

Trivia

• The "rd" before the version number stands for Minecraft:RubyDung, a game Notch was working on in early 2009 whose codebase was later reused for Minecraft.
• Level data is saved in a single Template:Cd file inside the game's root directory, unlike future versions that have dedicated folders.
• While the intended level size is 256×64×256, technically a world of any size can be loaded. However, worlds that are too small will have generation put on top of them, and worlds that are too large will fill the entire world and then get cut off.
• Grass blocks are stored using the same block ID as stone; the difference between them is purely visual.
• Despite normally only using 2 block IDs (0 and 1), 0–255 are all possible IDs. Invalid IDs appear as air, but do not get converted into it upon saving the world.
• Because of all of the above, theoretically any gzipped file called Template:Cd can be loaded as a world without issue, including a modern level.dat file. Note this will likely corrupt the file upon saving, due to the extra generation when the world is undersized, or the trimming applied when it is oversized, or simply any blocks placed/broken.
