Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[Nightly]

Added

  • decompile-secondary command to decompile secondary tilesets (#17)

  • -normalize-transparency option for the decompile commands (37668ac)(b710078)

  • -Wtile-index-out-of-range for use with the decompile commands (#18)

  • -Wpalette-index-out-of-range for use with the decompile commands (#18)

  • Options to disable generation of metatiles.bin and metatile_attributes.bin (#16)

    • -disable-metatile-generation and -disable-attribute-generation

  • Added support for -best-branches=smart pal assignment mode, which prunes populated + 1 number of branches per vertex (#18)

    • assign config search matrix now tries smart prune before trying a constant prune

Changed

  • Fixed bug from issue Secondary tileset attributes aren't generated #1

  • -Wkey-frame-missing-assignment now called -Wkey-frame-no-matching-tile

  • Subcommand help menus are much more refined, they now only show info relevant to the given subcommand (#51)

  • Build system overhaul, now using CMake (#62)

0.0.7 - 2024-01-07

Added

  • Palette assignment parameter search matrix: users no longer have to fiddle with a bunch of annoying options to find something that builds. It should work automatically in the background. Some additional options related to this functionality have been added.

  • Added a default-behavior option to specify default metatile behavior for missing attributes.csv entries

  • Also added default-terrain-type and default-encounter-type options

  • Manual palette assignment options now have a primary- version for use with compile-secondary

Changed

  • Updated libfmt dependency

  • Changed prune-branches option to best-branches, flag now works in reverse. I.e. best-branches tells the palette assignment search algorithm to only save the N best branches at each node.

0.0.6 - 2023-09-23

Added

  • Can now change default transparency color with -transparency-color option

  • Customizable warning system using GNU-like warning flags

  • Basic decompile mode for primary tilesets (secondary tilesets and animation decompilation still a WIP)

  • Multiple palette assignment backends controllable via command line options (this system is still a WIP)

Changed

  • Lots of improved error messages

  • Behavior header is now mandatorily supplied on the command line

0.0.5 - 2023-08-18

Added

  • Support for generating metatile_attributes.bin. Input path may contain an attributes.csv file that defines non-default values for any metatiles that should have non-default attributes. Both Emerald/Ruby and Firered style attributes are supported. Additionally, the input path should contain a metatile_behaviors.h file (I recommend you simply symlink your actual behavior header here) so that the attribute parser can understand the behavior macro names instead of working with hardcoded behavior values.

  • Support for dual-layer tilesets. Supply the -dual-layer option, and Porytiles will automatically infer the layer type from your layer PNGs, and put that type into the generate attributes bin file.

  • More warnings and errors, better printouts

Changed

  • Fieldmap configuration is a little different. Now, you can specify a target base game with the -target-base-game option (defaults to pokeemerald if not specified). Then, if your game uses adjusted fieldmap parameters, you can alter those with the fieldmap override options. E.g. to change the number of primary set palettes, use the -pals-primary-override option.

  • Animation generation now makes use of key frames. The key frame is the frame of tiles that you will use to reference an animated tile from within your layer PNGs. The key frame can be anything you want, as long as it is unique (note that each key frame tile must share a final hardware palette with the corresponding tiles in other frames, so you have a limitation there). You specify a key frame by putting key.png in your input anims folder. The key frame will not be compiled into the final anims folder, but you will see it present in your tiles.png.

0.0.4 - 2023-08-11

Added

  • Support for generating compiled animated tiles. If input path contains an anim folder with properly formatted RGBA anim assets, it will generate an anim folder in the output location with all anim frames correctly indexed. At the moment, the user must still manually enter the C code in tileset_anims.{c,h} to drive the actual animation.

  • Colored output, more descriptive error messages

  • -Wall and -Werror flags to turn on some helpful compiler warnings

Changed

  • Inputs are now provided in a given directory instead of as individual files

Removed

  • Raw compilation mode

0.0.3 - 2023-07-23

Added

  • Support for secondary tilesets using the --secondary flag. Secondary tilesets must consume the layer PNGs for their paired primary set, but then the compiler can use that information to take advantage of all the typical secondary tilset optimizations (like sharing palettes and tiles)

0.0.2 - 2023-07-19

Added

  • Generate metatiles.bin in addition to tiles.png and pal files (for primary tilesets only)

Changed

  • Complete algorithm overhaul from the 0.0.1 release
  • CLI has been updated significantly, please see the --help option for info

0.0.1 - 2023-06-12

Preview release.

Added

  • Basic functionality: Porytiles will allocate palettes and create an indexed tilesheet for most input images
  • Basic palette priming support: Porytiles allows you to force the palette allocation algorithm to guarantee that specified colors will be in the same palette
