1.1.5 for Minecraft 1.20.5

Upgrades to pack format 30 for Minecraft 1.20.5.

The migrations automated here are not exhaustive, so some manual work may still be required. See the release changelog for more information. This version of the tool applies specifically for splitting Map Decoration sprites. For GUI Sprite Slicer, see this release.

1.1.5 addresses an issue from 1.1.4 where the application would not start up correctly (#11, thanks @jedenastka!)

The assets/minecraft/textures/map/map_icons.png is accepted as input, and sprites are outputted to assets/minecraft/textures/map/decorations.

Usage

An installation of Java 17 or higher is required to run the tool.

Command-line arguments: <input dir or zip> <output dir> [<leftover dir>]

• input dir or zip is the root of your resource pack (directory or zip containing an assets directory)
• output dir will be filled with all processed texture files
• leftover dir is optional location that will be filled with copies of source images with added highlights for areas that were migrated
  • The highlighted areas were processed by the tool and are used by the Vanilla game, the rest is not required in the pack
