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. A tutorial is available.

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.

The maximum amount of spider eyes is increased by 1 per level of [[Looting]]. The chance of a spider '''not''' dropping any spider eyes can be found using the formula <code>2 / (Looting Level + 3)</code>. For example, Looting III gives a {{frac|1|3}} chance of not dropping any spider eyes. All other amounts have an equal chance of occurring. ==== Witches ==== [[Witch]]es have a chance of dropping 0–6 spider eyes upon death. This is increased by 3 per level of [[Looting]], for a maximum of 0-15 spider eyes. === Chest loot === {{LootChestItem|spider-eye}} == Usage == === Food === When [[Food|eaten]], a spider eye restores {{hunger|2}} [[Hunger|hunger points]] and 3.2 [[Hunger#Mechanics|saturation points]], giving a nourishment value of 1.6. It also applies a [[Poison]] [[effect]] lasting 5 seconds to the player, causing {{hp|4|poisoned=1}} damage, which reduces hunger/saturation by 6 points. === Crafting ingredient === {{crafting usage}}

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 20w13b, versions released in year 2020 still have # (c) 2019 Microsoft Corporation. in the license notice in the obfuscation map files.
