Revision as of 14:56, 19 July 2021
This page documents an unreleased version.
While there is proof of this version's existence, it was never released to the public.
rd-131655 is a pre-Classic version officially known as Cave game tech test [1] or Cave Game tech demo[2] was made on May 13, 2009, at 16:55 UTC.[3] This version was never released, but was recorded by Notch from around 17:00 UTC and uploaded at 17:36.[4] It is the first known version of Minecraft, or what was then known as Cave Game, to have been recorded.
Development of this version started around May 10[5] or May 11[6] and continued up to May 12, 2009.[7] Features were added that would be later seen in the Cave game tech test video released on May 13, 2009.
Additions
Blocks
- Not listed internally as a block at this time.
- Made with the same graphics from Notch's game RubyDung.
- 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 the top of the map, grass will generate on all fully lit tiles.
Non-mob entities
- Currently has no visible model.
- Has a height of 1.7 blocks.
World generation
- Take about 1⁄10 of a second to generate each.[8]
- The size of each chunk was 16×16 blocks.[9]
- Chunks are 16×16 blocks instead of 8×8 because 8×8 chunks decreased performance.[3]
- Chunks are loaded in order of their proximity to the player.[10]
- Make a 256×64×256 tile map.
- The game takes 20 seconds to generate a 256×64×256 map.[11]
- It was possible to fall out of the world.
- Falling off the edge of the world will not kill the player.
- Reached down until a few blocks before the last layer of cobblestone, making a ravine.
General
- The lighting engine in Classic and Pre-Classic was simple, with only two light levels, bright and dark. "Sunlight" is emitted by the top edge of the map and hits any block that is under it, regardless of distance. It passes through transparent blocks to light blocks underneath. Blocks that do not receive light are in a dim shadow that remains at the same level of brightness no matter how far they are from a light source. Blocks which are darkened also have a layer of thick, black fog applied to them, appearing darker when looked at from further distances. [verify] This caused weird visual glitches.
- Creative mode
- This was an extremely basic version of it. The player could not fly or place/remove blocks and there was no inventory or hotbar to get them from.
- The player can respawn by pressing a hotkey, teleporting them to the middle of the world.[more information needed]
Video
- Original
- Note: All videos from Nizzotch, Notch's YouTube channel, have been region-locked in all countries.
- Archive
Gallery
