GIS 1.1

These notes describe the changes introduced in Generic Inventory System 1.1.

Equipment system

Improvements

  1. Improved equipment groups and addressed network timing for equipment actors, so the equipment instance's begin-play callback waits for its actors to synchronize.
  2. Added EquipmentActorInterface so actors associated with an equipment instance can access its information.
  3. Added an interface to find an equipment slot from equipment.
  4. Fixed manual equipment activation, which previously required cycling an equipment group.
  5. Skip invalid or empty slots when cycling an equipment group.
  6. Added OnEquipmentTick to EquipmentInterface.

Item system

Improvements

  1. Improved item-definition validation logging.

Developer experience

  1. Added an editor module for creating common data assets from the Content Browser.
  2. Required attribute tags to start with GIS.Attribute.
  3. Added Fragment data validation for custom Blueprint and C++ validation rules.

Bug fixes

  1. Fixed a crash caused by the Mixin TargetObject not being replicated.
  2. Fixed incorrect owners in AttributeContainer and FragmentStateContainer when duplicating an item instance.
