# DA_EncounterData — Data Asset

**Parent Class:** `UDataAsset`
**Dependencies:** [`BPC_ProceduralEncounter`](../10-adaptive/70_BPC_ProceduralEncounter.md)
**Purpose:** Defines procedural encounter configurations — enemy types, spawn rules, difficulty scaling, and encounter triggers.

## Variables / Structure

| Field | Type | Description |
|-------|------|-------------|
| `EncounterTag` | `FGameplayTag` | Unique encounter identifier |
| `EnemyArchetypes` | `TArray<FPrimaryAssetId>` | Allowed enemy DA_AIProfile references |
| `MinEnemies` | `int32` | Minimum spawn count |
| `MaxEnemies` | `int32` | Maximum spawn count |
| `SpawnRadius` | `float` | Radius around trigger point (cm) |
| `SpawnDelay` | `float` | Time between individual spawns |
| `bTriggerOnOverlap` | `bool` | Auto-trigger on player overlap |
| `bTriggerOnAlert` | `bool` | Trigger when alert level reaches threshold |
| `RequiredAlertLevel` | `float` | Alert threshold (0.0-1.0) |
| `EncounterCooldown` | `float` | Min time between encounters |
| `DifficultyScaling` | `UCurveFloat*` | Curve for scaling enemy count/strength by difficulty |
| `NarrativePrerequisites` | `TArray<FGameplayTag>` | Narrative flags required |

---

## Gameplay Tags
- Namespace: `Encounter.<Type>.<Name>` (e.g., `Encounter.Ambush.Hallway`, `Encounter.Siege.Room`)

---

## Validation Rules
- `MinEnemies` must be >= 1
- `MaxEnemies` must be >= `MinEnemies`
- At least one `EnemyArchetype` required
- `SpawnRadius` must be > 0

---

## Example Data

| Field | Value |
|-------|-------|
| EncounterTag | `Encounter.Ambush.DarkCorridor` |
| EnemyArchetypes | `[DA_AIProfile_Crawler, DA_AIProfile_Stalker]` |
| MinEnemies | 2 |
| MaxEnemies | 5 |
| SpawnRadius | 800.0 |

## Consumed By
- [`BPC_ProceduralEncounter`](../10-adaptive/70_BPC_ProceduralEncounter.md)
- [`BPC_DifficultyManager`](../10-adaptive/62_BPC_DifficultyManager.md)

## Reuse Notes
- Encounter data is completely data-driven; spawning logic reads from this DA
- DifficultyScaling curve allows non-linear difficulty adjustment
- Narrative prerequisites gate encounters behind story progression
