# GetBatchProxyShapes(ReadOnlySpan<ProxyHandle>, Allocator)

> Get a batch of proxy user handles as shapes, valid only on a space bound to a world. On a bound space every proxy user handle is a shape, so each is returned as a shape that the caller can check for validity. This only applies to a space bound to a world.

## Definition

* **Type:** Method
* **Namespace:** [Unity.U2D.Physics](/engine/6000.7/script-reference/unity/u2d/physics.md)
* **Assembly:** UnityEngine.PhysicsCore2DModule

```csharp
public NativeArray<PhysicsShape> GetBatchProxyShapes(ReadOnlySpan<PhysicsSpace.ProxyHandle> proxyHandles, Allocator allocator = Allocator.Temp)
```

### Parameters

**** (\[ReadOnlySpan\<ProxyHandle>]\(https\://learn.microsoft.com/dotnet/api/system.readonlyspan-1)): The proxies to get.**** (\[Allocator]\(/engine/6000.7/script-reference/unity/collections/allocator)): The memory allocator to use for the results. This can only be [Allocator.Temp](/engine/6000.7/script-reference/unity/collections/allocator/temp.md), [Allocator.TempJob](/engine/6000.7/script-reference/unity/collections/allocator/tempjob.md) or [Allocator.Persistent](/engine/6000.7/script-reference/unity/collections/allocator/persistent.md).

### Returns

| Type                                                                                            | Description                                                                                                                                                                   |
| ----------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| [NativeArray\<PhysicsShape>](/engine/6000.7/script-reference/unity/collections/nativearray1.md) | The proxy shapes, one per proxy in the same order. This NativeArray must be disposed of after use otherwise leaks will occur. The exception to this is if the array is empty. |

### Remarks

See [PhysicsSpace.Create](/engine/6000.7/script-reference/unity/u2d/physics/physicsspace/create.md). The returned shapes are not guaranteed to still be valid, so check [\_isValid](/engine/6000.7/script-reference/unity/u2d/physics/physicsshape/isvalid.md) before use. If any proxy handle in the batch is invalid, no results are returned and an empty array is produced.
