Cave game tech test[2] is the name of a video released by Notch on May 13, 2009. While the version shown was never publicly available to play, it was developed from around May 10, 2009,[3] and showcased on May 13, 2009. It is the first known version of Minecraft, or Cave Game, as it was referred to in this time period.

Features[edit]

General[edit]

  • Physics
  • Lighting
    • Only 2 light levels
  • Chunks
  • World generation
    • 256×64×256 tile map.
  • Caves
    • Reached down until a few blocks before the last layer of cobblestone, making a ravine.
  • Creative mode
    • This was an extremely basic version of it. The player could not fly or place blocks and there was no inventory or hotbar to get them from.

Entities[edit]

  • The player
    • Currently has no visible model.
    • Has a height of 1.7 blocks.

Blocks[edit]

  • Blank.png Air
    • Not listed internally as a block at this time.
  • Cobblestone Revision 1.pngCobblestone
    • Made with the same graphics from Notch's game RubyDung.
  • Grass Block Revision 1.pngGrass
    • Made with the same graphics from RubyDung.
    • Grass generation is randomized, but it will only generate on fully lit tiles. The higher the Y level is, the more chance there will be of Grass generating. At Y=0, Grass will generate on ALL fully lit tiles. World generation cannot generate any blocks above Y=0.

Development[edit]

The Cave Game code was edited multiple times during the time it was developed. Here is a list of all known edits to the code:

  • Around May 10, 2009: Game first developed.[3]
  • May 12, 2009: Fixed a performance issue.[4]
  • May 13, 2009 (17:41 UTC): Notch made it only update two chunks per frame.[5] The game generates blank chunks and the FPS is inaccurate.
  • May 13, 2009 (17:48 UTC): Game now runs smoother.[6]
  • May 13, 2009 (17:51 UTC): Chunks have been changed from 8×8×8 to 16×16, and chunks near the player will load first.[7] This was the build that Notch showcased on his YouTube channel.
