c# - 无法从控件中读取“浮点”类型的值

Question

我正在尝试将 Dual Shock 4 控制器映射到新的输入系统，但我收到了这个错误：

InvalidOperationException: Cannot read value of type 'float' from control '/DualShock4GamepadHID/leftStick' bound to action 'Gameplay/Movement[/Keyboard/w,/Keyboard/s,/Keyboard/a,/Keyboard/d,/DualShock4GamepadHID/leftStick,/DualShock4GamepadHID/leftStick,/DualShock4GamepadHID/leftStick,/DualShock4GamepadHID/leftStick]' (control is a 'StickControl' with value type 'Vector2')

WASD 键有效，但我的控制器无效。

那是我的脚本：

using UnityEngine;
using UnityEngine.InputSystem;

public class CubeMovement : MonoBehaviour, PlayerControls.IGameplayActions
{
    private PlayerControls m_PlayerControls;
    private Vector2 m_Direction;
    [SerializeField] private float movementVelocity;

    private void Awake()
    {
        m_Direction = Vector2.zero;
        m_PlayerControls = new PlayerControls();
        m_PlayerControls.Gameplay.SetCallbacks(this);
    }

    private void Update()
    {
        var direction = Time.deltaTime * new Vector3(m_Direction.x, 0, m_Direction.y);
        transform.Translate(direction);
    }

    public void OnMovement(InputAction.CallbackContext context)
    {
        m_Direction = movementVelocity * context.ReadValue<Vector2>();
    }

    private void OnEnable()
    {
        m_PlayerControls.Gameplay.Enable();
    }


    private void OnDisable()
    {
        m_PlayerControls.Gameplay.Disable();
    }
}

那是我的配置：

我在网上找不到任何解决方案。好像我是第一个遇到这个问题的人。

要添加到上面的答案 - 要让 Sticks 注册为绑定的可用输入，还必须将 Action 设置为“Pass Through”和“Vector 2”
