Water/History - minecraft.fandom.com

This page would benefit from the addition of isometric renders. 

Please remove this notice once you've added suitable isometric renders to the article.
The specific instructions are:

To render:

• Pocket 1.0.0 Alpha 1.0.0.0 - "When viewed through glass, water now appears as a solid blue color, as opposed to a downward flowing water texture." (and Bedrock revert).
• Bedrock - "When viewed through glass, water now appears as its own top texture, as opposed to a downward flowing water texture."
• Playstation 4 1.78 - "The animation of water is now less smooth."
• JE 1.16 pre-release 5 - "Water overlay has been changed into a darker shade."

Water "items"[]

The following content is transcluded from Technical blocks/Water.

Appearances[]

Unknown
?					Water appears like this in the inventory. It appears about two pixels offset downwards compared to other cube items.
?					Water items, when dropped on the ground, appear much larger than other blocks.
Java Edition Infdev
20100607					A texture bug in this version results in water items containing some parts of the lava texture.
20100608					Water items are now fully water again.
20100611					All 3D rendered items, which currently includes water, now appear shaded slightly darker in the inventory.
20100615					Water items are now completely flat.
Java Edition
1.5		13w02a			Water items now use the still water texture likely due to texture storage reforms.
1.7.2		13w42a			Water items now appear translucent in the inventory. As a dropped item, in a player's hand, or in an item frame, they still appear opaque.
1.8		14w02a			Water items now appear translucent when held, in both first person and third person.
		14w05a			Water items now appear translucent when dropped or in an item frame.
Bedrock Edition
?					Water appears like this in the inventory.
?					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.
1.4.0		?			Due to water now receiving extensive biome tints, it appears gray in the inventory.
?					Water now appears tinted as an item. When held or dropped, it still appears gray.
?					Water no longer appears at twice the usual resolution in the player's hand.
Legacy Console Edition
?					Water exists as an item, using the old generated texture, however it appears as though it may be translucent in the inventory (but not when held).[5]
?					It appears 3D in the inventory, and is now translucent when held.

Names[]

Still Water[]

Java Edition

Item names did not exist prior to Beta 1.0.

• Beta 1.0 - 14w21b: Water
• (As block name, item does not exist) 14w25a and onwards: Water
• The blocks flowing and stationary water has been removed and water block has become generic. Generic water block's resource location is minecraft:water.

Bedrock Edition

• ? - ?: Water^[6]

Flowing Water[]

Java Edition

Item names did not exist prior to Beta 1.0.

• Beta 1.0 - 14w21b: Water

Texture generation prior to Java Edition 13w02a and Bedrock Edition v0.14.2[]

Still water[]

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

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 3x1 soup_heat neighborhood around the current element.
• Calculates the new soup_heat as the sum of the local_soup_heat divided by 3.3F plus the pot_heat times 0.8F
• Calculates the new pot_heat as the current pot_heat plus the flame_heat times 0.05. pot_heat is clamped to a minimum of 0.
• Calculates the new flame_heat as the current flame_heat minus 0.1F.
  • However, there is a 0.05 in 1 random chance that flame_heat is set to 0.5.

Once the above arrays have been updated, for each pixel in the water texture, the color and alpha values are calculated based on soup_heat:

• Calculates a color_heat as the soup_heat clamped between 0 and 1 inclusive.
• Then it calculates the color components of the pixel as follows:
  • float red = 32 + color_heat^2 * 32
  • float green = 50 + color_heat^2 * 64
  • float blue = 255
  • float alpha = 146 + color_heat^2 * 50

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

Flowing water[]

In addition, the flowing water texture also uses a spatial translation to give the appearance of movement. This transformation moves the flowing water 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.
