Item Effect Applier Component

Overview

UMIPItemEffectApplierComponent applies gameplay effects from usable items (e.g. consumables) to the player. It holds references to UMIPCharacterGameplayEffectsManager and UMIPFamilyGameplayEffectManager, subscribes to the ability system for active effect add/remove, and broadcasts friendly info for UI. ApplyUsableItemEffect(InUsablePieceAsset) is the entry point when a usable item is consumed.

Key traits:

  • Attachment: PlayerController.
  • Flow: OnPlayerStateReady → init managers; when usable item is used, ApplyUsableItemEffect applies the GE from the usable piece asset. Callbacks OnActiveGameplayEffectAddedCallback / OnRemoveGameplayEffectCallback broadcast ClientOnGameplayEffectAdded / ClientOnGameplayEffectRemoved.
  • Delegates: ClientOnGameplayEffectAddedDelegate(FMIPGameplayEffectFriendlyInfoOutputStruct), ClientOnGameplayEffectRemovedDelegate(EffectClass).
