# GCControllerAxisInput

A control element that tracks movement along an axis.

```
class GCControllerAxisInput
```

## Overview

A `GCControllerAxisInput` object represents the value of a physical controller’s axis. For example, a [`GCControllerDirectionPad`](/documentation/GameController/GCControllerDirectionPad) has x-axis and y-axis subelements.

## Topics

### Accessing the input values

[`value`](/documentation/GameController/GCControllerAxisInput/value)

The current value of the axis.

[`setValue(_:)`](/documentation/GameController/GCControllerAxisInput/setValue(_:))

Sets the normalized value of the axis.

### Getting change information

[`valueChangedHandler`](/documentation/GameController/GCControllerAxisInput/valueChangedHandler)

The block that the element calls when the user changes the axis value.

[`GCControllerAxisValueChangedHandler`](/documentation/GameController/GCControllerAxisValueChangedHandler)

The signature for the block that executes when the user changes the axis value.
