8.0 Migration Guide

This guide is incomplete. As v8 has not been fully released yet, it will continue to change until v8 fully stabilizes.

JSON Mods

If you have a JSON mod, you probably don't need to do anything. All existing JSON mods should still work, albeit with some changes to the way content is displayed on certain planets. See the section on 'Planets' below.

Java/JS Mods

Misc

  • Binding keybind values are now in camelCase.
  • The old keybind system has been completely reworked to allow for custom mod keybinds - see arc.input.KeyBind#add. Core.keybinds has been removed, use the Keybind class instead.

Blocks

  • Most unnecessary 'getter' methods (e.g. void tile(Tile), Tile tile(), block()) for Building have been removed. There was no reason to use these in the first place, but if your mod happened to do that, you'll need to access the field directly instead.
  • Blocks now have a separate lightClipSize field for drawLight() size clipping. emitLight must now be true in order for this method to be called.
  • loopSound has been removed; loops must be created and updated manually in the Building of each block. See Turret source code for examples.

Units

  • Player#unit() can now be null. Make sure you check that !player.dead() before accessing the unit.
  • Units.null has been removed.
  • Commands are now content. UnitCommand.all has been removed.
  • Unit commands are now a Seq, not an array.

Planets

  • All fields related to visibility of items (itemWhitelist, hiddenItems, Rules.hiddenBuildItems) have been removed. In order to make content show up on planet, change its shownPlanets field. If you have a tech tree set up for a planet, this will be done automatically.
