* Refactored the on_hit_effect into an element. (#85034) ## About The Pull Request on_hit_effect is now an element, which uses signals instead of callbacks. ## Why It's Good For The Game Easy peasy almost lemon squeezy. It's a good thing that I had made the AddElementTrait proc so we can manage multiple sources of a common element. It's much better to use signals than callbacks for components and datums with several possible sources, kinda like how it's been donw with the relay_attackers element. ## Changelog N/A * Refactored the on_hit_effect into an element. --------- Co-authored-by: Ghom <42542238+Ghommie@users.noreply.github.com>
