12 — Pickups and Effects

Status: Draft

• Scope (Batch 1 seed): Native ARIREffectActor mechanism + discovered Blueprint subclass paths. No overlap/authority graph inspection yet.
• Inspection method: Native C++ + search_subclasses.
• Last updated: 2026-07-16
• Current phase: Phase 1 — Static Architecture
• Last completed pass: Pass 2 (Batch 1)
• Next pass expected to contribute: Batch 4 Pass 10

Draft tracking

Completed sections

• ApplyEffectToTarget GE application path
• Instant/Duration GE class properties
• Blueprint child paths for potions / orange slice / mana crystal

Pending sections

• Per-pickup overlap, authority, destroy/respawn, UI notify
• Classification: GE vs direct DEPRECATED var mutation vs hybrid
• Gold / stamina pickups if present

Evidence still required

• Connected Blueprint graphs on each item BP
• Whether GetAbilitySystemComponent succeeds on player vs enemy targets

Native mechanism (Observed Implementation)

ARIREffectActor::ApplyEffectToTarget:

1. UAbilitySystemBlueprintLibrary::GetAbilitySystemComponent(TargetActor)
2. Early-out if null
3. MakeOutgoingSpec(GEClass, 1.f) + ApplyGameplayEffectSpecToSelf

Inferred: Intended pickup path is Gameplay Effect based for subclasses of this actor. Confirmation requires Blueprint graphs.
