# On Input System Event Float node

> [!NOTE]
> The On Input System Event Float node [!include[nodes-note-package](./snippets/input-system/nodes-note-package.md)]

The On Input System Event Float node lists for a specific Input Action from a Player Input component. The node can output a single float value. 

Use this node when you want to read user input and return a single value, such as an axis value or input from a trigger on a controller.

## Example graph usage 

In the following example, an On Input System Event Float node uses the bindings assigned to the **Lift** Input Action. When a user presses any key from the **Lift** binding, Visual Scripting takes the float value it receives from the Input System and sends it as an input to the Vector 3 Create node's **Y** input port. At the same time, Visual Scripting triggers the Transform Set Position node and uses the output from the Vector 3 Create node to set a new position for the Script Machine's GameObject.

For this example, **Lift** uses a Right Trigger from a Gamepad input device as a binding. When a user presses the Right Trigger, the **Y** value of the GameObject's transform increases, which makes the GameObject move upwards in the scene.
