Lava "items"

The following content is transcluded from Technical blocks/Lava.

Java Edition Classic
?					Lava has an extra, unobtainable item form corresponding to its block ID, which uses the "texture" rendered as a cube.
?					Flowing lava can be obtained via inventory editors with numeric item ID 10.
					Still lava can be obtained via inventory editors with numeric item ID 11.
0.24_SURVIVAL_TEST					Lava can be obtained as an item by having a creeper explode near it.
0.24_SURVIVAL_TEST_03					Explosions no longer drop lava as an item.
Java Edition Infdev
20100615					When placed, still lava items always remain still until receiving a block update. Flowing lava items spread immediately.
Java Edition Beta
1.6		Test Build 3			Lava items can be obtained from the newly added debug chests, mainly from the 10th slot of the 1st chest from the left, and the 21th slot of the 4th chest from the left.
					Flowing lava items can be obtained from the newly added debug chests, mainly from the 11th slot of the 1st chest from the left, and the 22nd slot of the 4th chest from the left.
		release			Debug chests no longer spawn, preventing lava and flowing lava items from being obtained this way.
Java Edition
1.3.1		12w16a			Lava items can now be obtained in singleplayer worlds via the /give command using the respective numeric IDs.
1.8		14w25a			The direct item forms of lava and flowing lava have been removed from the game. They can no longer exist as items in any way, only as placed blocks.
Pocket Edition Alpha
?					Lava exists as an item.

Appearances

Unknown
?					Lava appears like this in the inventory. It appears about two pixels offset downwards compared to other cube items.
?					Lava items, when dropped on the ground, appear much larger than other blocks.
Java Edition Infdev
20100607					A texture bug in this version results in lava items containing some parts of the water texture.
20100608					Lava items are now fully lava again.
20100611					All 3D rendered items, which currently includes lava, now appear shaded slightly darker in the inventory.
20100615					Lava items are now completely flat.
					When placed, still lava items always remain still until receiving a block update. Flowing lava items spread immediately.
20100616					In accordance with the change to lava itself, lava items now appear flowing rather than still.
Java Edition
1.5		13w02a			Lava items now use the still lava texture likely due to texture storage reforms.
Bedrock Edition
?					The item only appears animated when in the inventory or hotbar. When dropped, held or in an item frame, it appears completely stationary.
?					When held, the item uses the whole 32x32 flowing texture rather than the usual 16x16 section of it.
?					Lava now looks like this in the inventory.
?					Lava can now be obtained as an item through breaking surrounding blocks in a certain way.
?					Lava now appears tinted like water is in the inventory.
?					Lava now looks like this in the inventory.
?					Lava no longer appears at twice the usual resolution in the player's hand.

Still lava

Adapted from https://github.com/UnknownShadow200/ClassiCube/wiki/MInecraft-Classic-lava-animation-algorithm#lava

Every frame, for each position in the still water texture array, the respective values for soup_heat, pot_heat and flame_heat are calculated as detailed below:

• Calculates a local_soup_heat equal to the sum of the 3x3 soup_heat neighborhood around the current element but offset vertically by colSin******* and offset horizontally by rowSin*********.
  • rowSin is 1.2 times the sign of an angle that starts at 0 and changes by 22.5 degrees every row.
  • colSin is 1.2 times the sign of an angle that starts at 0 and changes by 22.5 degrees every column.
• Calculates a local_pot_heat equal to the sum of a 2x2 pot_heat neighborhood around the current pot_heat, with the current position being the upper left of the 2x2 neighborhood.
• Calculates the new soup_heat as the sum of the local_soup_heat divided by 10 plus the local_pot_heat divided by 4 times 0.8.
• Calculates the new pot_heat as the current pot_heat plus the flame_heat times 0.01***************. pot_heat is clamped to a minimum of 0.
• Calculates the new flame_heat as the current flame_heat minus 0.06.
  • However, there is a 0.005 in 1 random chance that flame_heat is set to 1.5.

Once the above arrays have been updated, for each pixel in the lava texture, the color values are calculated based on soup_heat (alpha is always opaque for lava):

• Calculates a color_heat as double the soup_heat clamped between 0 and 1 inclusive.
• Then it calculates the color components of the pixel as follows:
  • float red = color_heat * 100F + 155F
  • float green = color_heat^2 * 255F
  • float blue = color_heat^4 * 128F

The red, green and blue values are then converted to bytes and assigned to the texture accordingly.

Flowing lava

Flowing lava uses the exact same texture as still lava, however there is also a spatial translation to give the appearance of movement. This transformation moves the lava texture downwards by one pixel after a fixed amount of time,^{[more information needed]} wrapping the bottom layer of the texture back to the top.
