# On Mouse Down node

> [!NOTE]
> The On Mouse Down [!include[nodes-note-manual](./snippets/input-manager/nodes-note-manual.md)]

The On Mouse Down node listens for a mouse click action on a specific GameObject in your application. [!include[nodes-desc-end](./snippets/input-manager/nodes-desc-end.md)]

## Example graph usage 

In the following example, the On Mouse Down node listens for a click action on the GameObject where the graph runs. When a user clicks the GameObject, the On Mouse Down node triggers the GameObject Instantiate node. The Instantiate node creates a new GameObject, based on the **Ball** Prefab. It creates the Ball at a specific **Position**. It uses the Transform Get Local Rotation to match the new GameObject's **Rotation** to the GameObject where the Script Graph runs. Then, the graph adds a Rigidbody component to the new GameObject, and uses a Rigidbody Add Force node to add an **Impulse** force.

The Instantiate node uses inline values for its Original and Position, and takes its Rotation input from a Transform Get Local Rotation node targeting the parent GameObject of the Script Graph. The Instantiate node triggers a GameObject Add Component node, which adds a Rigidbody component to the newly-created GameObject. The Add Component node triggers a Rigidbody Add Force node, which uses the new Rigidbody component as its Target and inline values to apply an Impulse force.](images/vs-nodes-events-on-mouse-down-example.png)

When the user clicks the mouse button, the Script Graph creates a new **Ball** GameObject and sends it towards the camera.
