A version of Indev 0.31, also known as in-20100128-2304, was released on January 28, 2010, at 22:31 UTC.[1]



Diamond Ore JE1 BE1 Diamond ore
  • Not in Indev house block chest.
  • Drops 1-3 diamonds.
Block of Diamond JE1 Block of diamond
  • Not in Indev house block chest.
  • Drops itself.
  • Currently unobtainable without world editors.
Gear Gear[note 1]
  • Could only be obtained by inventory editing and was initially invisible in the inventory.[2]
    • At some point, this was changed to the animated version as seen when placed in the world.
  • A gear's sprite consisted of two parts; the center rod and the animated gear itself.
  • When hacked into the game, a gear could be placed anywhere, but would show nothing in its block space and was invisible unless horizontally adjacent to one or more blocks.
    • The placed gear would then show a gear sprite on the near side of each of those blocks.
  • A placed gear could not be destroyed by mining a block that its gear sprite was shown on, because the placed gear was actually adjacent to that block.
  • If the block a gear sprite was shown on was destroyed, the adjacent placed gear would no longer show that sprite.
    • Removing all blocks adjacent to a placed gear would remove all of its visible gear sprites, leaving the placed gear invisible.
  • Placed gears could not be destroyed directly by the player; attempts to do so would phase through to the block behind it, much like water.
    • A placed gear could only be removed by explosions.
  • Drops itself.

  • 1-3 are dropped from coal ore.
Diamond JE1 BE1 Diamond[3]
  • 1-3 are dropped from diamond ore.

World generation[]

Indev House
  • Items added to the tool chest.[3]
    • Iron sword.
    • All 16 new item types.


  • Pressing B opens the "Crafting" menu.[1]
    • Crafting is not fully functional yet[4], with the only available recipe being an apple (in the top left-hand corner box) or more than one apple (one of them must be in the top left-hand corner box) to an arrow.
    • Unlike with the inventory, the player can't move while crafting (just like versions newer than Java Edition Alpha v1.0.14_01).
    • The maximum item stack size is only 1 in a box of the "Crafting" menu.



  • Iron and gold ore now drop themselves.
  • Coal ore drops 1-3 coal.


  • Right-clicking on a stack picks up or puts down a single item.[1]
  • Left-clicking on a stack picks up or puts down the entire stack.[1]
    • It does not deposit more items than would create an item stack larger than the maximum stack size.
    • The remainder remains hovering at the pointer.
  • The player can no longer walk while having a chest open.
  • Maximum item stack size changed from 99 to 50 for items in the inventory, and 100 for items inside chests.[3]

World generation[]

Indev house
  • Size of starting item stacks in Indev house chests increased from 99 to 100.[3]


  • Fullscreen mode no longer affects GUI's, the Hotbar or displayed text.
  • Armor sprites will no longer display in their respective slots even if the level is reloaded.


From Indev 20091231-2

  • Due to the removal of armor sprites from in-game play, it is no longer possible to grab the sprites out.


  • Graphical glitch when game starts.[1]
    • Clicking corrects it.
  • Pressing a movement key at the same time as opening a chest causes that movement key to get "stuck".
  • It is possible to use more than one apple to craft an arrow. (See 1.4 Gameplay for some information).



  1. Evidence of gear introduction in this version:
    • The in-20100125-2 jar contains no gear textures.
    • The in-20100129 jar does contain gear textures, which are dated January 26, 2010 1:13-1:15 UTC.
    • Notch's January 26, 2010 1:36 UTC YouTube video displays functioning gears.
    • This is evidence that functional gears were in any version released between January 26, 2010 1:15 UTC and January 29, 2010 14:53 UTC.
      • That includes this version.
