Additions

Gameplay

Controls

• Placing and destroying blocks.
  • Left-click places a block. Right-click destroys a block.
  • Blocks cannot be placed beyond the world boundary.
  • The build limit is Y=64.
  • Added a flashing white overlay highlighting the face of the targeted block when hovering with the mouse.
• The level is saved when ⏎ Return or ⎆ Numpad Enter is pressed or when the game is exited.

Changes

World generation

General

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

Non-mob entities

Player

• Increased hitbox height to 1.8 blocks tall.

Removals

World generation

Caves

• No longer generate.

Bugs

3 bugs reported

• Blocks can be placed directly within the space occupied by the player. This bug remained in the game until 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 RubyDung, a game Notch was developing in early 2009 whose codebase was repurposed for Minecraft.
• Level data is saved in a single level.dat 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 level.dat can theoretically be loaded as a world, including a modern level.dat 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.
