# ClearCustomShapes

> Deletes a specific number of shapes defined by shapeCount starting at shapeIndex along with all associated vertices those shapes use.

## Definition

* **Type:** Method
* **Namespace:** [UnityEngine](/engine/6000.5/script-reference/unityengine.md)
* **Assembly:** UnityEngine.Physics2DModule

## ClearCustomShapes(int, int)

Deletes a specific number of shapes defined by `shapeCount` starting at `shapeIndex` along with all associated vertices those shapes use.

```csharp
public void ClearCustomShapes(int shapeIndex, int shapeCount)
```

### Parameters

**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): The index of the shape stored in the Collider.**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): The number of shapes to delete starting at the specified index.

### Remarks

Any existing contacts for this Collider will be recalculated during the next simulation step.

### Examples

```csharp
using UnityEngine;
using UnityEngine.Assertions;

public class Example : MonoBehaviour
{
    void Start()
    {
        // Fetch the custom collider.
        var customCollider = GetComponent<CustomCollider2D>();

        // Create a shape group.
        var shapeGroup = new PhysicsShapeGroup2D();

        // Add 5 Circles to the shape group.
        shapeGroup.AddCircle(center: new Vector2(3f, 0f),  radius: 0.5f);
        shapeGroup.AddCircle(center: new Vector2(4f, 0f),  radius: 0.5f);
        shapeGroup.AddCircle(center: new Vector2(5f, 0f),  radius: 0.5f);
        shapeGroup.AddCircle(center: new Vector2(6f, 0f),  radius: 0.5f);
        shapeGroup.AddCircle(center: new Vector2(7f, 0f),  radius: 0.5f);

        // Assign our shapes.
        customCollider.SetCustomShapes(shapeGroup);

        // Validate the contents of the custom collider.
        Assert.AreEqual(5, customCollider.customShapeCount);

        // Clear the first 2 shapes.
        customCollider.ClearCustomShapes(shapeIndex: 0, shapeCount: 2);

        // Validate the contents of the custom collider.
        Assert.AreEqual(3, customCollider.customShapeCount);

        // Clear the remaining 3 shapes.
        customCollider.ClearCustomShapes(shapeIndex: 0, shapeCount: 3);

        // Validate the contents of the custom collider.
        Assert.AreEqual(0, customCollider.customShapeCount);
    }
}
```

## ClearCustomShapes()

Deletes all the shapes and associated vertices for those shapes from the Collider.

```csharp
public void ClearCustomShapes()
```

        var shapeGroup = new PhysicsShapeGroup2D();

        // Add 5 Circles to the shape group.
        shapeGroup.AddCircle(center: new Vector2(3f, 0f),  radius: 0.5f);
        shapeGroup.AddCircle(center: new Vector2(4f, 0f),  radius: 0.5f);

        // Validate the contents of the custom collider.
        Assert.AreEqual(5, customCollider.customShapeCount);

        // Clear all the remaining shapes.
        customCollider.ClearCustomShapes();

        // Validate the contents of the custom collider.
        Assert.AreEqual(0, customCollider.customShapeCount);
    }
