# QueryParameters

> Creates a struct to set up parameters for batch queries: RaycastCommand, BoxcastCommand, CapsulecastCommand, SpherecastCommand.

## Definition

* **Type:** Struct
* **Namespace:** [UnityEngine](/engine/6000.0/script-reference/unityengine.md)
* **Assembly:** UnityEngine.PhysicsModule

```csharp
public struct QueryParameters
```

## Remarks

Use this struct to configure hit flags and layer mask. This supports hit triggers, hit backfaces and hit multiple Mesh faces.

Note: Only RaycastCommand supports hitting multiple Mesh faces.
