Modding Notes

• Upgraded game to Unity 2022.3.45f1
• Mods should target .NET Framework 4.8 to match Unity's supported .NET profile. Existing mods targeting 4.7.1 will still work.
• Specifying DLC requirements in IBuildingConfig has changed.
  • Deprecated GetDlcIds.
  • Added virtual methods GetRequiredDlcIds and GetForbiddenDlcId.
  • RegisterBuilding detects deprecated usage of GetDlcIds and converts to the new format so existing mods should continue to work.
• How to update your modded building configs:
  • AVAILABLE_ALL_VERSIONS -> Remove GetDlcIds
  • AVAILABLE_VANILLA_ONLY: Replace GetDlcIds with "public override string[] GetForbiddenDlcIds() => DlcManager.EXPANSION1;"
  • AVAILABLE_EXPANSION1_ONLY: Replace GetDlcIds with "public override string[] GetRequiredDlcIds() => DlcManager.EXPANSION1;"
• Specify DLC requirements for TechItems has changed.
  • Deprecated TechItem.dlcIds
  • Added TechItem.requiredDlcIds and TechItem.forbiddenDlcIds
  • Deprecated TechItem constructor with single dlc list. It converts dlcIds to requiredDlcIds and forbiddenDlcIds so existing mods should continue to work.
  • Deprecated DbTechItems.AddTechItem with DLCIds argument, use the one with requiredDlcIds and forbiddenDlcIds instead.
• IEntityConfigs have not been refactored yet and will be changed in a future update.
• Duplicant cheek shape now matches mouth shape instead of head shape.
• Worker class was refactored. StandardWorker now implements the behaviors previously implemented by Worker.

Fixes Since Beta
