### Examples

```csharp
using UnityEngine;
using UnityEngine.InputSystem;

public class Example : MonoBehaviour
{
    // Apply a force to a clicked articulationBody object.

    // The force applied to an object when hit.
    float hitForce;

    void Update()
    {
        if (Mouse.current.leftButton.wasPressedThisFrame)
        {
            RaycastHit hit;
            Ray ray = Camera.main.ScreenPointToRay(Mouse.current.position.ReadValue());

            if (Physics.Raycast(ray, out hit))
            {
                if (hit.articulationBody != null)
                {
                    hit.articulationBody.AddForce(ray.direction * hitForce);
                }
            }
        }
    }
