# CodeInputStep
> Numeric or code entry step completion.
**File:** `Assets/_MolcaSDK/_VR/Scripts/Scenario/Steps/CodeInputStep.cs`\
**Base:** [Step](/core/step)
## When to use
Use `Code Input Step` when a VR training scenario needs this specific interaction as a step in a sequence. Configure entirely in the Inspector — no code required.
## Role
Completes when the trainee enters the expected code sequence (see Inspector for length, validation, and UI hooks). Often pairs with shared [Modals](/shared/modals) / keyboard widgets.
## Code
**`CodeInputPanel.onCodeValidated`** → **`OnCodeValidated`** → **`ValidateCode`**; if valid, **`Complete()`**. Validation uses **`expectedCode`** only when **`useStepExpectedCode`** (panel-driven otherwise; **`onCodeValidated`** implies panel accepted input). **`autoShowPanel`**, **`showInVR`** + offset, **`hideOnComplete`**, **`resetOnActivate`** control UI.
```csharp theme={null}
using MolcaSDK.VR.Scenario;
public class PinLesson : UnityEngine.MonoBehaviour
{
public CodeInputStep step;
private void OnEnable()
{
step.SetExpectedCode("1234");
// step.ForceComplete(); // escape hatch
}
}
```
## Troubleshooting
* **No CodeInputPanel** — Assign or place **`CodeInputPanel`** on/under the same GameObject; auto-find runs in **`Initialize`**.
* **Always invalid** — If relying on step code, enable **`useStepExpectedCode`** and set **`expectedCode`** (or **`SetExpectedCode`**). Otherwise configure the panel’s own expected code so **`onCodeValidated`** only fires when correct.
* **Panel not visible in HMD** — Enable **`showInVR`**, adjust **`vrPositionOffset`**, ensure **`Camera.main`** exists for placement.
