Changes

World generation

General

• Level generation was redesigned from the irregular terrain shown in Minecraft:Cave game tech test to produce a completely flat world, similar to a modern Minecraft:superflat world.
• Terrain generates from Y=0 to Y=43.
• Space below Y=0 is empty.
• The top layer at Y=43 consists of Minecraft:grass blocks, while all lower terrain consists of Minecraft:stone.

Removals

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.
• On some systems, commonly those featuring Intel GPUs, there is extreme performance issues causing the framerate to drop to 1. This is caused by the block selection code using GL_SELECT based logic, involving individually re-rendering each face of nearby blocks, which is unperformant on some drivers.
• 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 shift as the camera rotates.

Trivia

• The "rd" prefix in the version title stands for Minecraft:RubyDung, a game Notch was developing in early 2009 whose codebase was repurposed 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.
• Although the intended world size is 256×64×256, worlds of any dimensions can be loaded. Worlds smaller than the intended size have terrain generated over them, while larger worlds are truncated.
• Grass blocks are stored using the same block ID (Block ID: 1) 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 these behaviors, nearly any gzipped file named Template:Cd can theoretically be loaded as a world, including a [[Minecraft:Java Edition level format#level.dat format|modern Template:Cd file]]. Saving such a world is likely to corrupt it because of terrain generation or truncation.

Notes

• Aside from the folders in the .jar file, the .class files and the contents of the folders remain unchanged, being last modified at May 13, 2009 at 22:09 at the latest.
