# ScenarioActivity

> Activity root linking SequenceController, steps, and scoring/session hooks.

**File:** `Assets/_MolcaSDK/_VR/Scripts/Scenario/ScenarioActivity.cs`

## Role

Groups a training **activity**: owns a [SequenceController](/core/sequence-controller), root [Step](/core/step) objects, and integrates with [Activity scoring](/vr/scoring/activity-scoring) and session posting when connected.

## Wiring

Configured on [ScenarioManager](/vr/scenario-manager) via the **`activities`** array (and/or scene hierarchy depending on your project pattern — confirm in scene prefabs).
