# GCDualSenseAdaptiveTrigger

A class that encapsulates the features of a DualSense adaptive trigger.

## Declaration

```swift
class GCDualSenseAdaptiveTrigger
```

## Overview

Overview A GCDualSenseAdaptiveTrigger object allows you to specify a dynamic resistance force that the DualSense controller applies when the user pulls the trigger. For example, set the resistance to give the user the feeling of pulling back on a bow string, firing a weapon, or pulling a lever.
