# DestroyShapeBatch

> Destroy a batch of shapes, destroying all PhysicsShape.Contact the shapes are involved in. Any invalid shapes will be ignored including chain segment shapes created via a PhysicsChain (the chain must be destroyed)." Owned shapes will produce a warning and will not be destroyed ( PhysicsShape.SetOwner ). See PhysicsBody.MassConfiguration.

## DestroyShapeBatch(ReadOnlySpan\<PhysicsShape>, bool)

Destroy a batch of shapes, destroying all [PhysicsShape.Contact](/engine/6000.7/script-reference/unity/u2d/physics/physicsshape/contact.md) the shapes are involved in. Any invalid shapes will be ignored including chain segment shapes created via a [PhysicsChain](/engine/6000.7/script-reference/unity/u2d/physics/physicschain.md) (the chain must be destroyed)." Owned shapes will produce a warning and will not be destroyed ([PhysicsShape.SetOwner](/engine/6000.7/script-reference/unity/u2d/physics/physicsshape/setowner.md)). See [PhysicsBody.MassConfiguration](/engine/6000.7/script-reference/unity/u2d/physics/physicsbody/massconfiguration.md).

```csharp
public static void DestroyShapeBatch(ReadOnlySpan<PhysicsShape> shapes, bool updateBodyMass)
```

### Parameters

**** (\[ReadOnlySpan\<PhysicsShape>]\(https\://learn.microsoft.com/dotnet/api/system.readonlyspan-1)): The shapes to destroy.**** (\[bool]\(https\://learn.microsoft.com/dotnet/api/system.boolean)): Whether to update the body mass configuration. Not doing so is faster, especially when destroying multiple shapes.

### Remarks

Use this method to destroy the shapes you create with [PhysicsBody.CreateShapeBatch](/engine/6000.7/script-reference/unity/u2d/physics/physicsbody/createshapebatch.md).

### Examples

```csharp
// Destroy a batch of shapes created with CreateShapeBatch.
using UnityEngine;
using Unity.Collections;
using Unity.U2D.Physics;

public class DestroyShapeBatchExample : MonoBehaviour
{
    void Start()
    {
        PhysicsWorld world = PhysicsWorld.defaultWorld;
        PhysicsBody body = world.CreateBody();
        using NativeArray<CircleGeometry> circleGeometries = new NativeArray<CircleGeometry>(
            new[] { new CircleGeometry { radius = 1f } }, Allocator.Temp);

        NativeArray<PhysicsShape> shapes = body.CreateShapeBatch(circleGeometries, PhysicsShapeDefinition.defaultDefinition);
        PhysicsWorld.DestroyShapeBatch(shapes, updateBodyMass: true);
        shapes.Dispose();
    }
}
```

## DestroyShapeBatch(ReadOnlySpan\<PhysicsShape>, bool, int)

Destroy a batch of shapes, destroying all contacts the shapes are involved in. Any invalid shapes are ignored, including chain segment shapes created by a chain, which must be destroyed through their owning chain instead. A shape owned by a different owner key is skipped and left valid; a shape with no owner, or one matching the given owner key, is destroyed. One summary warning reports how many shapes were skipped this way, rather than one warning per shape.

```csharp
public static void DestroyShapeBatch(ReadOnlySpan<PhysicsShape> shapes, bool updateBodyMass, int ownerKey)
```

### Parameters

**** (\[ReadOnlySpan\<PhysicsShape>]\(https\://learn.microsoft.com/dotnet/api/system.readonlyspan-1)): The shapes to destroy.**** (\[bool]\(https\://learn.microsoft.com/dotnet/api/system.boolean)): Whether to update the body mass configuration. Not doing so is faster, especially when destroying multiple shapes.**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): Optional owner key returned when using [PhysicsShape.SetOwner](/engine/6000.7/script-reference/unity/u2d/physics/physicsshape/setowner.md).

### Remarks

See [PhysicsShape.Contact](/engine/6000.7/script-reference/unity/u2d/physics/physicsshape/contact.md), [PhysicsChain](/engine/6000.7/script-reference/unity/u2d/physics/physicschain.md), [PhysicsBody.MassConfiguration](/engine/6000.7/script-reference/unity/u2d/physics/physicsbody/massconfiguration.md) and [PhysicsShape.SetOwner](/engine/6000.7/script-reference/unity/u2d/physics/physicsshape/setowner.md).
