# collider

> The Collider2D detected by the physics query.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.0/script-reference/unityengine.md)
* **Assembly:** UnityEngine.Physics2DModule

```csharp
public Collider2D collider { get; }
```

### Remarks

When the [RaycastHit2D](/engine/6000.0/script-reference/unityengine/raycasthit2d.md) result is returned from a physics query, the `collider` refers to the specific [Collider2D](/engine/6000.0/script-reference/unityengine/collider2d.md) that was detected.

**NOTE**: This field will be NULL if nothing was detected however when checking if the result is valid, you should use the less verbose method shown in the code example below.

### Examples

```csharp
using UnityEngine;

public class ExampleClass : MonoBehaviour
{
    public Vector2 direction;

    void Update()
    {
        // Cast a ray in the specified direction.
        RaycastHit2D hit = Physics2D.Raycast(transform.position, direction);

        // If something was hit, delete the specific Collider we hit.
        if (hit)
            Destroy(hit.collider);
    }
}
```
