Patch notes for The Binding of Isaac: Afterbirth+

By Michelle-Louise Janion,
Yep! That's right!

  • Fixed a Windows crash caused by an exe modification step in the build process
  • Fixed a crash related to loading a game save after smelting trinkets
  • Fixed a crash on startup related to save data
  • Fixed a crash involving an item that would try to spawn doors in Greed/Greedier mode
  • Fixed a bug where the player could be hurt by certain fires spawned by their own items
  • Fixed a bug where the boss clear music could play too soon
  • Adjusted steam cloud save detection
  • Various adjustments for balance and fairness
Mod tools:
  • Fixed a display issue and some default path issues with room editor
  • Fixed a Mac issue with missing libraries that made the Mac ModUploader
  • impossible to launch without a specific dev environment installed
Modding API:
  • Generated comments for HTML documentation
  • Added descriptions of mod callback conditions, arguments and return values, in enums.lua and in HTML documentation
  • Changed signature of MC_EVALUATE_CACHE callback to pass the player entity
  • Removed some duplicated casts: Isaac.ToPickup and Isaac.ToEffect. Instead use entity:ToPickup and entity:ToEffect
  • Added some missing entity casts: ToBomb, ToLaser, ToKnife
  • Added some methods to player to get joystick inputs
  • Made player stats modifiable by mods
  • Removed getters for readonly player stats, since they were made redundant
  • Added functions such as Isaac.WorldToScreenPosition to convert game coordinates to rendering coordinates
To the brave intrepid Lua modders: We heard your criticism and we understand. It's still early days for the modding API. You can look forward to new possibilities as we open up access to more of the game's features and create more samples for you to base your mods on. We're still mostly focused on bug fixing at this time, so please be patient. This isn't even our final form!

In the mean time, there are some sample mods made by the dev team that have been lurking the dark corners of the workshop. They're collected here.

I tend to favour the puzzle, RPG, action-adventure and strategy genres. My particular favourites over the years have been Final Fantasy IX, Metal Gear Solid, Civilisation V and The Last of Us. I'm also a sucker for a series: Darksiders, Assassin's Creed, Tomb Raider etc.

I am a bit of a lone gamer as I tend to steer clear of PvP, and only play multiplayer with close friends.
