Obfuscation map

Obfuscation maps are Proguard mappings from old (original) names to new (obfuscated) names for classes and class members that have been renamed. They have been exported in the client.json for every snapshot and release available in the Launcher since 19w36a, and the client.json for 1.14.4 has been updated slightly after 19w36a's release to include obfuscation maps as well.

Usage

The obfuscation maps can be used to remap obfuscated stack traces (as in crash reports) to readable stack traces.

Dinnerbone and Adrian Östergård have suggested that the obfuscation maps may make modding easier. Searge has implied that the obfuscation maps can replace certain third-party programs such as the Mod Coder Pack.

Third party usages

The obfuscation maps include enough information to deobfuscate Minecraft for decompilation. Third-party programs may exist for this purpose.

According to the License, such decompiled source code is restricted to internal and reference use.

Every obfuscation map file starts with a line indicating the license of the maps.

1.15 {{Extension DPL}}<ul><li>[[Charcoal|Charcoal]]<br/>{{Item | image = Charcoal.png |type= | renewable = Yes | stackable = Yes (64) }} '''Charcoal''' is an [[item]] obtained by smelting [[log]]s or [[wood]]. It is used as fuel, or for crafting [[torch]]es and [[campfire]]s. Unlike [[coal]], charcoal cannot be traded with [[villager]]s or crafted into a [[block of coal]]. Coal and charcoal also cannot stack together. It can be used as a substitute for coal, as both charcoal and coal have an equivalent duration when smelted. == Obtaining == === Breaking === A [[campfire]] broken without the [[Silk Touch]] enchantment drops 2 charcoal. === Smelting === {{Smelting |Any Log; Any Stripped Log; Any Wood; Any Stripped Wood |Charcoal |foot=1 |0,15 }} === Compound creation === Charcoal can be created from its base [[element]]s, using the [[compound creator]].{{only|bedrock|education}} {| class="wikitable" !Name !Elements !Example recipe |- <!-- Temporarily using crafting grid as substitute for compound creator (template not yet available), since the layout is the same, even if the appearance is different --> !Charcoal |7 Carbon<br>4 Hydrogen<br>1 Oxygen |{{Crafting Table |shapeless= 1 |A2=Carbon,7 |B2=Hydrogen,4 |C2=Oxygen |Output=Charcoal}} |} == Usage == === Crafting ingredient === {{crafting usage|Charcoal}} {{Crafting |B1= Stick |A2= Stick |B2= Coal; Charcoal |C2= Stick |A3= Any Log or Stem; Any Stripped Log or Stem; Any Wood or Hyphae; Any Stripped Wood or Hyphae |B3= Any Log or Stem; Any Stripped Log or Stem; Any Wood or Hyphae; Any Stripped Wood or Hyphae |C3= Any Log or Stem; Any Stripped Log or Stem; Any Wood or Hyphae; Any Stripped Wood or Hyphae |Output= Campfire }} === Lab table ingredient === Charcoal is one of the [[lab table]] ingredients needed to produce the [[heat block]].{{only|education}} {| class="wikitable" !

Charcoal used as fuel lasts more than 5 times longer than [[wood planks]] or [[wood]] logs used as fuel, being more efficient than any other use of wood for smelting in ''[[Java Edition]]'', but outstripped by [[wooden slabs]] in Bedrock. Coal and charcoal are also the only fuels accepted by [[Minecart with Furnace|furnace minecarts]]. They provide approximately four minutes of transit each. == Data values == === ID === {{edition|java}}: {{ID table |edition=java |showforms=y |generatetranslationkeys=y |displayname=Charcoal |spritetype=item |nameid=charcoal |itemtags=coals |form=item |foot=1}} {{edition|bedrock}}: {{ID table |edition=bedrock |showitemtags=y |showaliasids=y |shownumericids=y |showforms=y |notshowbeitemforms=y |generatetranslationkeys=y |displayname=Charcoal |spritetype=item |nameid=charcoal |aliasid=coal / 1 |id=303 |itemtags=minecraft:coals |form=item |foot=1}} == Achievements == {{load achievements|Renewable Energy}} == History == {{History|java beta}} {{History||December 25, 2010|link=http://www.minecraftforum.net/topic/131047-lantern-update-incoming/page__st__20#entry1986964| In 0.3.2, charcoal was suggested to [[Markus Persson|Notch]] by [https://twitter.com/Moleculor @Moleculor] on [[wikipedia:Twitter|Twitter]] as a writing implement.}} {{History||1.2|[[File:Charcoal JE1 BE1.png|32px]] Added charcoal, with the same texture as coal. |Charcoal is not used as a writing implement.}} {{History|java}} {{History||1.2.1|snap=12w04a|Charcoal can now be used to craft [[fire charge]]s.}} {{History||1.3.1|snap=?|Charcoal is now directly available in the creative inventory.}} {{History|||snap=1.3|[[File:Charcoal JE2 BE2.png|32px]] The texture of charcoal has been changed.}} {{History||1.6.1|snap=13w19a|[[File:Charcoal JE3 BE3.png|32px]] The texture of charcoal has been changed.}} {{History||1.8|snap=14w02a|Charcoal can no longer be [[trading|traded]] from [[villager]]s.}} {{History||1.13|snap=17w47a|The different data values for the {{code|coal}} ID have been split up into their own IDs. |Prior to [[1.13/Flattening|''The Flattening'']], this [[item]]'s numeral ID was 263.}} {{History||1.14|snap=18w43a|[[File:Charcoal JE4 BE4.png|32px]] The texture of charcoal has been changed.}} {{History|||snap=19w02a|Charcoal can now be used to craft [[campfire]]s.

September 4, 2019					Dinnerbone releases obfuscation mappings for 1.14.4 as well.

Trivia

• Out of all Java Edition versions published after 19w36a (September 4th, 2019), Combat Test 3 is yet the only one published without any obfuscation map.

• Unlike previous Combat Tests, the version it forked against, 1.14.4, has obfuscation maps released.
• All consequent Combat Tests have obfuscation maps released, and are based off versions with obfuscation maps released.

• As of 20w06a, versions released in year 2020 still have # (c) 2019 Microsoft Corporation. in the license notice in the obfuscation map files.
