How can I assign an input device to a specific player?

Unity Engine

Hello everyone,
I’m trying the new input system in Unity, it’s really amazing. I’d developing a little local multiplayer game and I was wondering, how can I assign a specific input (gamepad, keyboad etc.) to the player?
I want to thank everyone in advance and sorry for my English.

Depends on what your setup is.

With PlayerInput, either spawn the players with the given devices or switch devices on the existing PlayerInput instances.

// Spawn players with specific devices.
var p1 = PlayerInput.Instantiate(playerPrefab, controlScheme: "Gamepad", pairWithDevice: Gamepad.all[0]);
var p2 = PlayerInput.Instantiate(playerPrefab, controlScheme: "KeyboardMouse", Keyboard.current, Mouse.current);

// Switch devices later.
p1.SwitchCurrentControlScheme("KeyboardMouse", Keyboard.current, Mouse.current);

With the generated C# wrappers, assign the devices for the player to “devices” property.

m_Actions = new MyPlayerActions();
m_Actions.devices = new[] { Keyboard.current , Mouse.current };

Rene please could you help me?
I am triying to assing two different controllers without spawning the players with this part of your code : “p1.SwitchCurrentControlScheme(“KeyboardMouse”, Keyboard.current, Mouse.current);”. The problem came when both controllers are ps4 controllers and both players dont distinguish each controller. If I spawn the players there are not any problem, but I do not want to do this.
Thank you :).

@maximill101 please create a new thread with more details instead of necroing old ones: Unity Community Code of Conduct - legacy

While I am here I may as well point you to this thread where I had a similar desire:

Rene-Damm’s example is good but i think it is old.
So If you are looking for a solution without using buit-in PlayerInput component and Instantiating, my example code is below:

using UnityEngine;
using UnityEngine.InputSystem;
using UnityEngine.InputSystem.Utilities;

[RequireComponent(typeof(Rigidbody))]
public class LocalPlayerController : MonoBehaviour
{
    [SerializeField] private float moveSpeed = 5f;
    [SerializeField] private float rotationSpeed = 720f;
    [SerializeField] private PlayerInputType playerInputType = PlayerInputType.KeyboardMouse;
    private ReadOnlyArray<InputDevice> keyboardMouseDevices = new ReadOnlyArray<InputDevice>(new InputDevice[] { Keyboard.current, Mouse.current });
    private ReadOnlyArray<InputDevice> gamepadDevice = new ReadOnlyArray<InputDevice>(new InputDevice[] { Gamepad.current});

    private Rigidbody rb;
    private Vector3 movement;
    private LocalPlayerInput input;

    void Start()
    {
        rb = GetComponent<Rigidbody>();
        input = new LocalPlayerInput();
        input.Enable();
        input.devices = playerInputType == PlayerInputType.KeyboardMouse ? keyboardMouseDevices : gamepadDevice;
        input.LocalPlayer.Enable();
    }

    void Update()
    {
        Vector2 dir = input.LocalPlayer.Movement.ReadValue<Vector2>();
        movement = new Vector3(dir.x, 0.0f, dir.y).normalized;

        if (movement != Vector3.zero)
        {
            Quaternion toRotation = Quaternion.LookRotation(movement, Vector3.up);
            transform.rotation = Quaternion.RotateTowards(transform.rotation, toRotation, rotationSpeed * Time.deltaTime);
        }
    }

    void FixedUpdate()
    {
        rb.MovePosition(rb.position + movement * moveSpeed * Time.fixedDeltaTime);
    }
}

public enum PlayerInputType
{
    KeyboardMouse,
    Gamepad
}

Assign it to your player prefab and duplicate it and change Player Input Type for both of them.

And here is my Input Actions:
