All **`StepAuxiliary`** types are added on each [Step](/core/step) via the **SerializeReference / Auxiliaries** list in the Inspector (menu paths come from **`[AuxiliaryMenu(...)]`** on each class). ## When to use | Need | Use | | ---------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Step **title** (and often description) for HUD **task lists** + modals | **`StepInfo`** auxiliary — see below | | Per-step points / time / binary scoring + optional session post | **[StepScoringAuxiliary](/vr/scoring/step-scoring-auxiliary)** | | Pulses or continuous buzz on begin / complete / reset | **VRHapticAuxiliary** | | Floating labels + button rim highlights on controllers | **VRControllerInfoAuxiliary** | | Different UnityEvents for tutorial vs training vs assessment | **StepModeAwareEvent** | | Radial / text feedback for valve, knob, gaze | **`AnalogFeedbackUI`**, **`ProgressFeedbackUI`**, **`ValveFeedbackUI`** (referenced from [ValveStep](/vr/steps/valve-step) / [KnobStep](/vr/steps/knob-step) / [LookAtStep](/vr/steps/look-at-step) via [SceneObjectReference](/core/reference-system)) | ### StepInfo (task list + copy) **`StepInfo`** is a **`StepAuxiliary`** (same **Auxiliaries** list on [Step](/core/step)) that holds the **human-facing title** and related copy for a step. * **[Scenario UI](/vr/scenario-ui)** — in-scenario HUD often includes a **task / checklist** UI: it walks the active steps (via the running [SequenceController](/core/sequence-controller) / [ScenarioActivity](/vr/scenario-activity)) and shows each step’s **`StepInfo`** title as a row so trainees see **what to do next** and what’s already done. * **Modals** — steps such as [Popup step](/vr/steps/popup-step) read **`StepInfo`** for title/body text on confirmation dialogs. * **Subclasses** — you can derive from **`StepInfo`** to add fields (extra labels, icons, CSV-imported metadata). [CSV Step Importer](/core/csv-step-importer) supports a custom **`StepInfoType`** and **`RegisterExtraColumnMapping`** so imported steps get your derived auxiliary. Scenario UI and importers that cast to your type can show the extra data; the stock **task list** typically relies on the **base title** (and localization) from **`StepInfo`**. Add **`StepInfo`** through **Auxiliaries →** the menu entry your SDK exposes (often under a **VR / Scenario** or **Info** path). Keep titles **localized** (e.g. **`DynamicLocalization`**) when the task list and modals use the same keys as the rest of the UI. ### Auxiliary types (summary) | Type | Role | | ----------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **StepInfo** | **Title/description** (and subclasses for extra fields); feeds **[Scenario UI](/vr/scenario-ui)** task-list rows and modal copy ([Popup step](/vr/steps/popup-step)). | | **StepScoringAuxiliary** | Embedded **ScoringConfig**; **`OnStepUpdate`** refreshes time-based scores; **`FinalizeScore`** on complete/end; optional **`PostStepScoreAsync`**. | | **VRHapticAuxiliary** | **`HapticImpulse[]`** via **`HapticImpulsePlayer`** on [VRPlayerManager](/vr/vr-player-manager) controller visuals (or scene fallback by name). Optional **continuous** haptics until complete. | | **VRControllerInfoAuxiliary** | **`InfoDisplayUtility`** + **`VRInfoDisplay[]`** (hand, button, **`DynamicLocalization`**, optional prefab). Toggles controller appearance mode and **`SetButtonRim`** while active. | | **StepModeAwareEvent** | **`beginExecutionModes`** / **`completeExecutionModes`** flags vs **`ScenarioDataConfig.ExecutionMode`**; invokes **`UnityEvent`** when mode matches. | ## Code **Add an auxiliary in the Editor** — expand the Step component → **Auxiliaries** → add **VR/Haptic Feedback**, **VR/Controller Info**, **VR/Scenario/Mode Event**, or **Scoring/Step Scoring**. No code required for haptics or mode events if you wire impulses / UnityEvents in the Inspector. **Runtime: drive binary / accuracy scoring** (e.g. from a custom script listening to your own validation): ```csharp theme={null} using MolcaSDK.VR.Scenario.Scoring; // step = hosting Step MonoBehaviour var aux = step.GetAuxiliary(); aux.SetCorrect(); // binary aux.SetAccuracy(0.85f); // 0–1 for Accuracy type aux.SetAccuracyPercent(85f); ``` **Analog / progress UI** — steps call **`AnalogFeedbackUI.Setup(IAnalogInteraction, target, start)`** then **`Show()`** / **`Hide()`**; **`ProgressFeedbackUI.SetProgress(0..1)`** from gaze dwell. ## Troubleshooting * **Auxiliary never runs** — Confirm it lives on the **same Step** instance the [SequenceController](/core/sequence-controller) activates; check **IsEnabled** on the auxiliary instance if your version exposes it (**StepModeAwareEvent** bails when disabled). * **VRHapticAuxiliary: no channels** — Add **`HapticImpulsePlayer`** to **`VRControllerVisual`** children or ensure controller objects include **left/right** in the name for fallback search. * **VRControllerInfoAuxiliary: no popups** — Place **`InfoDisplayUtility`** in the scene; **`localizedInfo`** must not be **disabled**; **`GetButtonTransform`** must exist for the chosen **`VRControllerVisual.ButtonType`**. * **Mode event never fires** — **`ScenarioDataConfig.GetInstance()`** must return config with expected **`ExecutionMode`**; masks must include that mode in **begin** / **complete** flags. * **Analog UI blank** — Call **`Setup`** before **`Show`**; **`IAnalogInteraction`** must be the live valve/knob; radial **Image** must use **Filled** + **Radial** per inspector tooltips. * **Task list shows wrong or empty titles** — Each listed step needs a **`StepInfo`** auxiliary with **title** (and localization) set; confirm **Scenario UI** references the same **SequenceController** / activity the player is training on. ## Related * [Scenario UI](/vr/scenario-ui) — completion + in-scenario HUD (task list uses **`StepInfo`** titles) * [Step scoring auxiliary](/vr/scoring/step-scoring-auxiliary) * [ScoringConfig](/vr/scoring/scoring-config) * [Step (base class)](/core/step) * [VR player manager](/vr/vr-player-manager) * [Scenario Data Config](/setup/scenario-data-config) — execution mode ## Unity Editor Unity Inspector Step auxiliaries list
