+# Interaction Systems — Asset Creation Sheet (8 assets)
+
+> **UE5 Path:** `Content/Framework/Interaction/`
+
+---
+
+## BPC_InteractionDetector (Component)
+
+**Parent:** `ActorComponent` → Attach to player pawn
+
+| Variable | Type | Default |
+|----------|------|---------|
+| `InteractionRange` | Float | `300.0` |
+| `InteractionChannel` | TraceChannel | `Visibility` |
+| `HoldDuration` | Float | `0.5` |
+| `CurrentFocusedActor` | Actor | None |
+
+**Key Logic:**
+```
+Tick → LineTraceByChannel(Camera Forward * Range)
+  ├─ Hit actor implements I_Interactable?
+  │   True → if different from CurrentFocused → Call OnFocusBegin on new, OnFocusEnd on old
+  │   False → Clear focus
+  ├─ If holding interact → accumulate hold timer
+  │   Timer >= HoldDuration → trigger OnInteract
+  └─ Fire dispatchers: OnFocusBegin, OnFocusEnd, OnHoldProgress
+```
+
+**Dispatchers:** `OnInteractionDetected(Actor, PromptText)`, `OnFocusLost`, `OnHoldProgress(Float)`
+
+---
+
+## I_HidingSpot (Interface)
+
+**Create:** Right-click → **Blueprint → Blueprint Interface** → Name: `I_HidingSpot`
+
+| Function | Inputs | Outputs |
+|----------|--------|---------|
+| `CanPlayerHide` | `Player` (Actor) | `Boolean`, `BlockReason` (Text) |
+| `OnPlayerEnter` | `Player` (Actor) | — |
+| `OnPlayerExit` | `Player` (Actor) | — |
+| `GetEntryTransform` | — | `Transform` |
+| `GetPeekTransforms` | — | `Array<Transform>` |
+| `IsOccupied` | — | `Boolean` |
+| `GetHidingSpotType` | — | `GameplayTag` |

+## Test These
+- [ ] Walk up to door → prompt "Open Door [E]" → press E → door opens
+- [ ] Locked door → prompt "Locked — Requires Key Card" → can't open
+- [ ] Run toward low wall → auto-vault (ContextualTraversal)
+- [ ] Grab physics object → drags in front of player → release throws
