• changelog
• wiki documentation for new IteratingSystem family hook (+ reversed order for calls)
• verify version in test games

---

Changelog:

• NEW (BREAKING CHANGE): new onInit function of a system which gets called after the world is configured
  • the creation of entities in a system's constructor now throws an exception. Such logic must be moved to the onInit function. This is a necessary change to keep consistency of hooks and families in that specific scenario. [#123: aggregated family hooks that trigger IntervalSystems #128]
• NEW: new onEnable / onDisable functions for systems to react on enabled changes. [#124: add onEnabled/onDisabled functions to IntervalSystem #127]
• NEW: new FamilyOnAdd / FamilyOnRemove interfaces that can be used on IteratingSystem to add family hooks for the system's family in an easier way. Refer to the wiki for more details. [#123: aggregated family hooks that trigger IntervalSystems #128]
• UPDATE: Update versions:
  • Kotlin 1.9.21
  • kotlinx.serialization 1.6.2
  • Gradle 8.5
• UPDATE: onEntityRemoved of a family is now called BEFORE the entitiy's components are removed. [Proposal: Component add/remove hooks that don't rely on Component.onAdd/onRemove #120]
• UPDATE: Fixed an issue that you can write it += Component which broke Fleks internally. This was introduced with the Tags feature and will now show you a compile error again. [FleksNoSuchEntityComponentException: Entity has no component of type 'BComponent'. #125]
• UPDATE: Systems onDispose and systems' onRemoveEntity functions are called in reverse order. Before, the order was the order of systems of the world. [#129 reverse system dispose and entity onRemove order. #130]
• UPDATE: extracted the sorting logic of a system to a separate onSort function and made the sorting attributes protected instead of private. This allows a better support for overriding the onTick function, if needed. [Make iterating system private sorting-related fields protected. #133]
