Detect Game Controllers

Learn how to detect controllers in your application.
Read time 1 minuteLast updated 23 days ago
Unity includes the Game Controller framework in the project only if a script in the project references 
Input.GetJoystickNames
. If it’s available, Unity iOS Runtime loads the framework dynamically.
To get the list of all available controllers, call 
Input.GetJoystickNames
. You can re-check this list at any time to detect if controllers have been attached or detached.
You can call this API to detect the type of controller that's attached. Names follow the pattern: 
[$profile_type,$connection_type] joystick $number by $model
. 
$profile_type
can be either basic or extended, and 
$connection_type
is either wired or wireless. When Unity detects at least one controller, you can either disable on-screen touch controls or amend them to supplement controller input.

Example: Detect attached Game Controllers

The following code sample checks whether any controllers are connected to the device.
using System.Collections;using UnityEngine;public class GameControllers : MonoBehaviour{    private bool connected = false;    IEnumerator CheckForControllers() {        while (true) {            var controllers = Input.GetJoystickNames();            if (!connected && controllers.Length > 0) {                connected = true;                Debug.Log("Connected");                        } else if (connected && controllers.Length == 0) {                         connected = false;                Debug.Log("Disconnected");            }            yield return new WaitForSeconds(1f);        }    }    void Awake() {        StartCoroutine(CheckForControllers());    }}
