# 11 — UI, HUD, and Sessions

**Status: Draft**

- **Scope (Batch 1 seed):** Native HUD / widget-controller / attribute-delegate path; Advanced Sessions plugin presence. No widget tree or session Blueprint flow yet.
- **Inspection method:** Native C++ read; PluginToolset; subclass seeds.
- **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 Passes 4 + 10

## Draft tracking

### Completed sections
- InitOverlay call chain from player InitAbilityActorInfo
- OverlayWidgetController attribute broadcasts/bindings
- AdvancedSessions / AdvancedSteamSessions enabled + descriptor paths
- Widget subclass path seeds

### Pending sections
- Main menu / browser / character-select widget flow
- Production vs Example Advanced Sessions Blueprints
- WBP_Overlay / progress bar bindings
- CommonUI usage

### Evidence still required
- Whether HUD class defaults assign OverlayWidgetClass / ControllerClass
- Session create/find/join graphs

## HUD init (Observed Implementation)

`ARIRPlayerCharacter::InitAbilityActorInfo` → `ARIRHUD::InitOverlay(PC, PS, ASC, AS)` → create `OverlayWidgetClass` → `UOverlayWidgetController` binds ASC attribute delegates → `BroadcastInitialInitialValues` → `AddToViewport`.

checkf text references `WBP_PlayerHUD` for class assignment.

**Subclass seeds:** `WBP_Overlay`, health/mana progress bars, `BP_OverlayWidgetController`.

**Technical Debt:** Stamina delegates reuse Mana signature types in OverlayWidgetController.h.

---

## Sessions (Observed Implementation)

Project plugins AdvancedSessions + AdvancedSteamSessions enabled (VersionName 5.8). Depend on OnlineSubsystem / Steam stack.

**Unknown:** Live menu usage vs `/Game/_Main/Blueprints/Examples/ExampleAdvancedSessionsFunctionsChar` — Batch 4 Pass 4.

**Unknown:** No OnlineSubsystem INI under project `Config/` — Requires Broader Filesystem/Configuration Inspection.
