## Definition

* **Type:** Method
* **Namespace:** [UnityEngine](/engine/6000.7/script-reference/unityengine.md)
* **Assembly:** UnityEngine.ParticleSystemModule

```csharp
public ParticleSystem.MinMaxCurve GetVector(ParticleSystemCustomData stream, int component)
```

### Parameters

**** (\[ParticleSystemCustomData]\(/engine/6000.7/script-reference/unityengine/particlesystemcustomdata)): The name of the custom data stream to retrieve the curve from.**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): The component index to retrieve the curve for (0-3, mapping to the xyzw components of a Vector4 or float4).

### Returns

| Type                                                                                     | Description                                   |
