# 03 — Class Hierarchy
|
||
|
||
**Status: Draft**
|
||
|
||
- **Scope:** Native C++ hierarchy under `Source/REALMSINRUIN/` plus Blueprint parent chains, interfaces, and framework Blueprints inspected in Batch 2 Pass 3.
|
||
- **Inspection method:** Batch 1 native reads; Batch 2 read-only AssetTools tags/deps + BlueprintTools graphs/events/variables; ObjectTools CDO properties.
|
||
- **Evidence classifications used:** Observed Implementation, Documented Intent, Inferred, Unknown.
|
||
- **Tool or visibility limitations:** Inherited Blueprint variables require querying each parent; CustomEvent FunctionFlags not exposed via ObjectTools; Gunslinger FiB/IsDataOnly anomaly.
|
||
- **Last updated:** 2026-07-16
|
||
- **Current phase:** Phase 1 — Static Architecture
|
||
- **Last completed pass:** Pass 5 (Batch 2)
|
||
- **Next pass expected to contribute:** Batch 3 Pass 6 (per-character ability graphs)
|
||
|
||
## Draft tracking
|
||
|
||
### Completed sections
|
||
- Full native class inventory (Batch 1)
|
||
- Blueprint parent chains for players, enemies, PC/PS, GI/GM
|
||
- Interface inventory under `/Game/_Main/Blueprints/Interfaces`
|
||
- WBP_PlayerHUD asset-class resolution (AHUD, not UserWidget)
|
||
- BP_PlayerState DefaultAttributesGameplayEffect = None
|
||
|
||
### Pending sections
|
||
- Deep child ability graphs (Pass 6)
|
||
- Enemy AI graph deep dive (Pass 9)
|
||
- Frontend/session graphs (Pass 4)
|
||
|
||
### Evidence still required
|
||
- Exact CustomEvent reliable flags
|
||
- Who invokes `PlayerDeath` from damage
|
||
- CommonUI content usage

## 1. Characters (native — Batch 1 summary)
|
||
|
||
See Batch 1 sections for `ARIRBaseCharacter`, `ARIRPlayerCharacter`, `ARIRBaseEnemyCharacter` native details. Key contradictions unchanged: enemy ASC on self vs base `GetAbilitySystemComponent` from PlayerState; `DefaultAttributesGameplayEffect` unused in C++.

### 2.2 Playable children (structural)
|
||
|
||
| Character | Path | Parent | IsDataOnly | Local vars | Ability-related implemented events |
|
||
|-----------|------|--------|------------|------------|-------------------------------------|
|
||
| Paladin | `.../Paladin/Player_Paladin` | BP_PlayerCharacterBase_C | False | Ability001Montages, ChargeStartLoc, ChargeFinishLoc, IsCharging, IsBlocking | Server_001 Begin; 002 Begin+End; 003 Begin; 004 Begin; UseAbility001/004; Charge; Client_Charge |
|

**AnimBP (Paladin sample):** Mesh AnimClass = `/Game/_Main/Animations/PlayerCharacters/Human/CharacterClasses/Paladin/ABP_Paladin`
|
||
|
||
**Naming:** Use `Player_Amazonian` (not Amazon). BPI_PlayerCharacter deps list Amazonian/Cleric/Paladin/Wizard — **not Gunslinger**.

## 4. Player framework Blueprints
|
||
|
||
### 4.1 `PC_Character`
|
||
|
||
| Field | Value |
|
||
|-------|--------|
|
||
| Path | `/Game/_Main/Blueprints/Player/PC_Character` |
|
||
| Parent | RIRPlayerController |
|
||
| Interface | BPI_PlayerController (GetPC_DungeoneerReference) |
|
||
| Variables | CharacterSelectHUD |
|
||
| Implemented events | ServerSpawnCharacter, ReceiveBeginPlay, PlayerFirstSpawn, PlayerSelectScreenChoice, PlayerRespawn |
|
||
| CDO IMC | `/Game/_Main/Blueprints/Player/Inputs/IMC_PlayerDefault` |
|
||
| CDO MovementInput | `/Game/_Main/Blueprints/Player/Inputs/Movement/IA_Movement` |
|
||
|
||
### 4.2 `BP_PlayerState`
|
||
|
||
| Field | Value |
|
||
|-------|--------|
|
||
| Path | `/Game/_Main/Blueprints/Player/BP_PlayerState` |
|
||
| Parent | RIRPlayerState |
|
||
| IsDataOnly | True |
|
||
| Variables | [] |
|
||
| Implemented events | BeginPlay, Tick |
|
||
| **DefaultAttributesGameplayEffect** | **None** (Observed Implementation on CDO) |
|
||
|
||
---
|
||
|
||
## 5. Game framework Blueprints
|
||
|
||
| Asset | Parent | Notes |
|
||
|-------|--------|-------|
|
||
| `/Game/_Main/Blueprints/Game/GameInstance/GI_Dungeoneer` | GameInstance | IsDataOnly; no implemented events; empty deps |
|
||
| `/Game/_Main/Blueprints/Game/GameMode/GM_Dungeoneer` | GameModeBase | BPI_GameMode; vars PlayerStartLocations, ConnectedPlayers, Player Stats; events PostLogin/Logout/BeginPlay/GetSelectedClass |
|
||
| `/Game/_Main/Blueprints/Game/GameMode/GM_MainMenu` | GameModeBase | IsDataOnly; deps PC_MainMenu, BP_MainMenuPawn |
|
||
|
||
**GM_Dungeoneer CDO (Observed Implementation):**
|
||
|
||
- HUDClass = `WBP_PlayerHUD_C`
|
||
- PlayerControllerClass = `PC_Character_C`
|
||
- PlayerStateClass = `BP_PlayerState_C`
|
||
- DefaultPawnClass = None (spawn via PC flow)
|
||
|

|
||
|
||
## 6. Interfaces discovered
|
||
|
||
| Interface | Path | Key graphs |
|
||
|-----------|------|------------|
|
||
| BPI_PlayerCharacter | `/Game/_Main/Blueprints/Interfaces/BPI_PlayerCharacter` | UseAbility001–004, SetIsAttacking, InitializeHUD, GetPlayer*REF, DEPRECATED_Recover*, AddKill_PlayerCharacter |
|
||
| BPI_EnemyCharacter | `.../BPI_EnemyCharacter` | GetEnemyREF, AddPlayerTarget, EnemyMeleeAttack |
|
||
| BPI_PlayerController | `.../BPI_PlayerController` | SetPlayerCanMove, UpdatePlayerHUD, PlayerRespawn, PlayerSelectScreenChoice, PlayerFirstSpawn, AddGold, GetPC_DungeoneerReference, AddKill_PlayerController |
|
||
| BPI_GameMode | `.../BPI_GameMode` | GetPlayerStats (on GM_Dungeoneer) |
|
||
|
||
No separate ability/damage/targeting/session BPI assets under `/Game/_Main/Blueprints/Interfaces` beyond the four above.
|
||
|
||
---
|
||
|
||
## 7. WBP_PlayerHUD resolution
|
||
|
||
| Field | Value |
|
||
|-------|--------|
|
||
| Path | `/Game/_Main/UI/Widgets/HUD/WBP_PlayerHUD` |
|
||
| Asset class | `WBP_PlayerHUD_C` |
|
||
| Parent | `/Script/REALMSINRUIN.RIRHUD` (**AHUD**) |
|
||
| IsDataOnly | True |
|
||
| Verdict | **AHUD Blueprint**, not a Widget Blueprint. `WBP_` prefix is misleading. |
|
||
| Referencers | `GM_Dungeoneer` |
|
||
| Dependencies | REALMSINRUIN, `WBP_Overlay`, `BP_OverlayWidgetController` |
|
||
|
||
Resolves Batch 1 subclass-search anomaly: ObjectTools returned this asset under RIRHUD search because it **is** an RIRHUD child.
|
||
|
||
---
|
||
|
||
## 8. Native RPCs
|
||
|
||
**Observed Implementation:** Still no native Server/Client/Multicast UFUNCTIONs in `Source/REALMSINRUIN`. All ability networking is Blueprint-only (`05`).
|
||
|
||

|
||
|
||
## Contradictions
|
||
|
||
| Topic | Evidence A | Evidence B | Better supported |
|
||
|-------|------------|------------|------------------|
|
||
| Enemy ASC access | Enemy ASC on self | Base GetASC from PlayerState | Both Observed; interface path likely broken for enemies |
|
||
| Default attributes | GE assets exist; property on PS | BP_PlayerState CDO = None; never applied in C++ | Property unused; apply path still Unknown / missing |
|
||
| HUD naming | `WBP_PlayerHUD` name suggests widget | Parent is RIRHUD (AHUD) | AHUD — name is Documented Intent mismatch |
|
||
| Dual HUD systems | Native InitOverlay → WBP_Overlay + ASC | BP Server_UpdateHUD → DEPRECATED floats → UpdatePlayerHUD | Both Observed Implementation; incomplete GAS migration |
|
||
| Gameplay Abilities | URIRGameplayAbility Documented Intent | No GA assets; legacy Server_Ability_* | Legacy BP abilities active |
|
