The entire system is tag-driven and fully generic. The `Narrative.Flag.*` and `Narrative.Phase.*` namespaces are empty by default — fill them per project with game-specific flags. Add new numeric value types (reputation, corruption, etc.) by simply calling `SetValue` with the appropriate tag. No code/blueprint changes needed.

## Manual Implementation Guide
|
||||
|
||||
### Class Setup
|
||||
1. Create Blueprint Class: Parent = `ActorComponent`, Name = `BPC_NarrativeStateSystem`
|
||||
2. Add to Player Character or GameState (if shared)
|
||||
3. Implement Interface: `I_Persistable`
|
||||
|
||||
### Variable Init (BeginPlay)

||||

||||
├─ Set MaxHistorySize = 500
|
||||
└─ If implementing I_Persistable: register with SS_SaveManager
|
||||
```
|
||||
|
||||
### Function Node-by-Node
|
||||
|
||||
#### `SetFlag(Tag: GameplayTag, Value: Boolean)` → `void`
|
||||
```
|
||||
Step 1: OldValue = NarrativeFlags.Find(Tag) or false
|
||||
Step 2: NarrativeFlags.Add(Tag, Value) ← Map Add (overwrites if exists)
|
||||
Step 3: If Value == true AND OldValue == false:
|
||||
NarrativeHistory.Add(Tag)
|
||||
If NarrativeHistory.Length > MaxHistorySize: Remove oldest entry
|
||||
Step 4: Fire OnFlagChanged(Tag, Value)
|
||||
Step 5: Notify I_Persistable: Mark dirty for save
|
||||
```
|
||||
**Nodes:** `Map Find`, `Map Add`, `Array Add`, `Array Length`, `Remove Index 0`
|
||||
|

```
|
||||
ForEach Tags:
|
||||
If GetFlag(ArrayElement) == false → Return false
|
||||
Return true
|
||||
```
|
||||
|
||||
#### `CollectState()` → `S_WorldObjectState` *(I_Persistable)*
|
||||
```
|
||||
Step 1: Create S_WorldObjectState
|
||||
Step 2: Serialize NarrativeFlags: ForEach → store (Tag, Value) as string pairs in CustomData
|
||||
Step 3: Serialize NarrativeValues similarly
|
||||
Step 4: Return struct
|
||||
```
|
||||
|
||||
#### `RestoreState(Data: S_WorldObjectState)` *(I_Persistable)*
|
||||
```
|
||||
Step 1: Clear NarrativeFlags, NarrativeValues, NarrativeHistory
|
||||
Step 2: Parse CustomData → ForEach entry → NarrativeFlags.Add(Tag, BoolValue)
|
||||
Step 3: Parse values → NarrativeValues.Add(Tag, FloatValue)
|
||||
```

Adding a new objective type (like timed objectives) requires adding an `S_TimedObjective` struct extension and a timer function — no system redesign needed.
