Encouragement and flammability of sponge, signs in PE

Jocopa3, would you be able to look into the encouragement and flammability values of sponge and signs, in PE, for their entries in the Burning Blocks table? – Sealbudsman ^talk/_contr 20:14, 6 December 2016 (UTC)

I don't believe pocket edition has values for either, I believe it uses the block thickness variable to factor how long it takes for a block to burn or if the block can catch fire from lava; I can look into this further in the next day or two to figure out exactly how that works. The other part is that groups of blocks have special material types, and the block material is what determines if it's flammable or not. Sponges are in a material group that isn't flammable, so I'm curious why they're listed as a burning block. Jocopa3 (talk) 07:09, 7 December 2016 (UTC)

For comparison, in computer edition, flammability isn't a property encapsulated by the other blocks, it's just a list maintained in BlockFire ... if you are able to look at BlockFire in Mod Code Pack, you'll see a big list of block flammabilities/encouragements right at the top of the class, which the fire block uses to know what blocks it can spread onto. That's where I've been getting those values from.

As for sponge, I'm not sure where that came from. It doesn't seem to burn away in Win 10 0.16.2, though, so it's either old, or never was right. – Sealbudsman ^talk/_contr 13:25, 7 December 2016 (UTC)

Now I see; those values are indeed set in the FireBlock constructor in PE. I created a table by filtering out the assembly code in the FireBlock constructor in PE 1.0.0; the table contains all blocks that have encouragement and flammability values and can be found here.

Edit: It's worth noting that some values differ in PE, such as Wool Carpet and 1-block tall flowers (RedFlower and YellowFlower blocks) Jocopa3 (talk) 18:37, 7 December 2016 (UTC)

Very nice, thanks. I've updated the table to suit these values. It's kind of getting messy-looking though ... – Sealbudsman ^talk/_contr 19:20, 7 December 2016 (UTC)

Hay bales, 1-block flowers and coal blocks

Jocopa3, would you be able to check these blocks in PE, to find whether they catch fire in the presence of just lava (no pre-existing fire whatsoever)? (in PC, this is reported as MC-109948) And perhaps also the blocks from the Fire#Non-flammable blocks section (in PC, reported as MC-3263)? – Sealbudsman ^talk/_contr 19:26, 7 December 2016 (UTC)

The only two blocks that differ are: the bed block which doesn't catch fire at all near lava, and dead bushes which do catch fire near lava but don't burn. All other blocks behave the same as the PC version. Jocopa3 (talk) 02:10, 8 December 2016 (UTC)

Flammable Table Formatting

Should the non-flammable blocks table be formatted so that PC and PE values are on different rows, or the same row like it currently is? For the former, this is what it'd look like with the bed and dead bush block rows:

Jocopa3 (talk) 07:14, 8 December 2016 (UTC)

Sure! Yes I think that looks great. – Sealbudsman ^talk/_contr 12:53, 8 December 2016 (UTC)

New blocks?

Given none of the new blocks are listed (I came looking for barrels), I'm guessing this page hasn't been updated to the new fire mechanics. --MentalMouse42 (talk) 10:54, 26 June 2019 (UTC)

Old renders?

For whatever reason, I seem to think that fire used to render as two faces in an "X" shape, similar to flowers. Did fire ever appear like that? According to the history section, it never did. But I feel like it did, at some point. Could someone just tell me 'yes' or 'no'? I thought this was an interesting point and it's been bugging me ever since I read the 'history' section :P --2057clones (talk) 23:54, 27 April 2020 (UTC)

Not as far as I know. FVbico (talk) 00:06, 28 April 2020 (UTC)

Crimson & Warped Planks

In Bedrock Edition Crimson & Warped planks catch fire but do not burn. --Universespy (talk) 10:38, 22 October 2020 (UTC)

Fire Spreading and Block Burning Math Equations

Is it possible to add a math equation to show how fire spreads and how blocks burn? I know some math nerds like me out there might enjoy having that so they can calculate the chance of those events happening. Blazester101 (talk) 22:08, 28 July 2021 (UTC)

Fire age

What is the "fire age"? Does it show how old the fire is? 99.252.150.246 14:09, 7 November 2021 (UTC)

It is a property of fire block which defines how much long the block existed. When reaches certain amount of time, block disappears (unless the block is on netherrack). Umucraft (talk) 16:41, 4 December 2022 (UTC)

If obtaining fire item is "impossible", what about this?

Here is the code which used for registering ItemBlocks(1.8-1.8.9):

registerItemBlock(Blocks.fire)

Code for 1.9-1.12.2:

registerItemBlock(Blocks.FIRE)

Code for 1.13 and onwards:

public static final Item FIRE = registerBlock(Blocks.FIRE)

Here is the screenshot (1.19.2):

Here is the screenshot (1.12.2):

This method is possible with modified game, but not in vanilla version. Deshman-gpuser (talk) 13:38, 4 December 2022 (UTC)

Are there any instructions for obtaining these items? The 1.19.2 screenshot seems to indicate it's possible in a somewhat vanilla environment given the top left. - User-12316399 (talk) 13:42, 4 December 2022 (UTC)

Also see this edit: [1]. About version naming, game usually dosen't detect small changes to classes, hence no "modified" prefix. Deshman-gpuser (talk) 13:52, 4 December 2022 (UTC)

Yes, this is only possible with modification or backporting (at least to 14w21b), Deshman-gpuser. But there is no way to handle this problem other than modding or backporting because in 13w37a obtainment method of items has changed (usage of resource locations was added), further changes to item rendering were made in 14w25a, when custom item models was added and item models has become non-hardcoded. With this changes, most of direct item form of technical blocks was removed by adding method registerItemBlock (which registers an ItemBlock). Before this, all blocks (excluding air) had an direct item form (some of technical blocks have indirect item forms, such as cake, sugar cane, redstone repeater and comparator. Fortunately they are still not removed). Umucraft (talk) 16:09, 4 December 2022 (UTC)

About instructions, User-12316399. The in-game instructions does not accept "minecraft:item/fire" (or in-game "minecraft:fire") such as /give and /item (was "replaceitem", renamed). In order to force the game to accept resource location "minecraft:item/fire" (technical) or "minecraft:fire" (in-game), modification (modding) or backporting (at least to 14w21b) is required.
