# Core step types

> ParallelStep, AnimationStep, IntCounterStep, FloatListenerStep, and other non-VR steps.

**Folder:** `Packages/com.molca.core/Runtime/Sequence/Step/`

Molca Core ships these `Step` subclasses beyond the base [Step](/core/step):

| Type                                          | Description                                                                               |
| --------------------------------------------- | ----------------------------------------------------------------------------------------- |
| **[ParallelStep](#)**                         | Run child steps concurrently. Completes when configurable completion rules are met.       |
| **[AnimationStep](#)**                        | Plays a Unity `Animation` or `Animator` clip on activation, completes when the clip ends. |
| **[DelayStep](/core/delay-step)**             | Waits a configurable duration (pauses correctly on sequence pause).                       |
| **[IntCounterStep](#)**                       | Tracks an integer counter; completes when the count reaches a target value.               |
| **[FloatListenerStep](#)**                    | Monitors a float value; completes when it crosses a threshold.                            |
| **[BranchingStep](/core/branching-step)**     | Activates exactly one child step from an array by index at runtime.                       |
| **[ConditionalStep](/core/conditional-step)** | Binary true/false branch — activates `trueStep` or `falseStep` child.                     |
| **[InputStep](#)**                            | Waits for a configurable input action (key, button, axis).                                |

VR-specific step scripts live under `_MolcaSDK/_VR/Scripts/Scenario/Steps/` (see navigation).

## Code

Core steps are plain **`Step`** subclasses. Example shape (names vary — open `ParallelStep.cs` etc. in `_Core/Sequence/Step/`):

```csharp theme={null}
using Molca.Sequence;
using UnityEngine;

public class TimedGateStep : Step
{
    [SerializeField] private float delay = 1f;

    protected override void OnStepActivated()
    {
        base.OnStepActivated();
        Invoke(nameof(Complete), delay);
    }
}
```

For authoring nested graphs in-editor, use [Sequence Visualizer](/core/sequence-visualizer) and [CSV Step Importer](/core/csv-step-importer).
