A version of Indev 0.31 was released on January 28, 2010, at 22:00–22:02 UTC,^[1] which added new tools, blocks and items. It was announced on The Word of Notch at 22:31 UTC.^[2]

0.31 block and item additions

Block of emerald^[a]

• Currently unobtainable without world editors.
• Not in the starting house chest.

Emerald ore^[a]

• Drops 1–3 emeralds.

Gear^[b]

• Can only be obtained by inventory editing and initially invisible in the inventory.^[4]
• A gear's sprite consists of two parts; the center rod and the animated gear itself.
• When hacked into the game, a gear can be placed anywhere, but would show nothing in its block space and would be 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 cannot be destroyed by mining a block that its gear sprite is shown on, because the placed gear is actually adjacent to that block.
  • If the block a gear sprite is shown on is 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 cannot be destroyed directly by the player; attempts to do so would phase through to the block behind it, much like water.
  • A placed gear can only be removed by explosions.
  • Later replaced by redstone dust.

Coal^[5]

• 1–3 are dropped from coal ore.

Emerald^[5][a]

• 1–3 are dropped from emerald ore.

Gold ingot^[5]

• There are 100 of them in the starting house, but is otherwise unobtainable.

Iron ingot^[5]

• There are 100 of them in the starting house, but is otherwise unobtainable.

Iron Sword

• Readded.

Emerald axe, pickaxe, shovel and sword^[5]

Stone axe, pickaxe, shovel and sword^[5]

Wooden axe, pickaxe, shovel and sword^[5]

Crafting

• Pressing B opens the "Crafting" menu.^[2]
  • Currently unobtainable in this version.^[6]

Gold ore

• Now drop themselves.

Iron ore

• Now drop themselves.

General

• Items now show as 3D voxel sprites.^[2][5][7]

Swords

• Swords mine 1.5 times faster than by hand.

Starting house

• Size of starting item stacks in starting house chests increased from 99 to 100.^[5]
• Items added to the tool chest.^[5]
  • Iron sword.
  • All 16 new item types.

Hotbar

• Fullscreen mode no longer affects the hotbar.

Inventory

• Fullscreen mode no longer affects GUIs or displayed text.
• Armor sprites no longer display in their respective slots even if the level is reloaded.

Controls

• Right-clicking on a stack picks up or puts down a single item.^[2]
• Left-clicking on a stack picks up or puts down the entire stack.^[2]
  • 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.^[5]

1 bug fixed

From Indev 0.31 20091231-2255

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

5 bugs reported

• Crafting menu does not open when pressing B^[6]
• Blocks and arrows each form separate stacks in the inventory^[8]
• Graphical glitch when game starts.^[2]
  • Clicking corrects it.
• Pressing a movement key at the same time as opening a chest causes that movement key to get "stuck".
• The game progressively degrades in performance.
