前言

官方文档Input System：链接: Input System
安装部分：链接: Unity XR Interaction Toolkit的安装（二）

一、XRI Default Input Actions

1.导入官方案例

需要导入官方案例：Starter Assets，方便学习

2.设置控制器绑定，如手柄、主/辅助按钮、操纵杆等

1.要设置控制器绑定，如左右手 手柄、主/辅助按钮、操纵杆等，请双击：XRI Default Input Actions

2.获取左手XY键事件（右手AB同理）

选择顺序 XR Controller–>XR Controller (RightHand)或者XR Controller(LeftHand)–>Usage

二、按键对应名称

三、代码示例

代码如下（示例）：

using UnityEngine;
using UnityEngine.InputSystem;

namespace TWQ
{
    public class MenuManage : MonoBehaviour
    {
        public InputActionReference MyLeftButton_X;
        public InputActionReference MyLeftButton_Y;

        public InputActionReference MyRightButton_X;
        public InputActionReference MyRightButton_Y;

        private void OnEnable()
        {
            SetupInteractorEvents();
        }
        private void OnDisable()
        {
            TeardownInteractorEvents();
        }
        void SetupInteractorEvents()
        {
            //左手
            var MyLeftButton_X_Action = GetInputAction(MyLeftButton_X);
            if (MyLeftButton_X_Action != null)
            {
                MyLeftButton_X_Action.performed += OnMyLeftButton_X_Action;
            }
            var MyLeftButton_Y_Action = GetInputAction(MyLeftButton_Y);
            if (MyLeftButton_Y_Action != null)
            {
                MyLeftButton_Y_Action.performed += OnMyLeftButton_Y_Action;
            }
            //右手
            var MyRightButton_X_Action = GetInputAction(MyRightButton_X);
            if (MyRightButton_X_Action != null)
            {
                MyRightButton_X_Action.performed += OnMyRightButton_X_Action;
            }
            var MyRightButton_Y_Action = GetInputAction(MyRightButton_Y);
            if (MyRightButton_Y_Action != null)
            {
                MyRightButton_Y_Action.performed += OnMyRightButton_Y_Action;
            }

        }
        void TeardownInteractorEvents()
        {
            var MyLeftButton_X_Action = GetInputAction(MyLeftButton_X);
            if (MyLeftButton_X_Action != null)
            {
                MyLeftButton_X_Action.performed -= OnMyLeftButton_X_Action;
            }
            var MyLeftButton_Y_Action = GetInputAction(MyLeftButton_Y);
            if (MyLeftButton_Y_Action != null)
            {
                MyLeftButton_Y_Action.performed -= OnMyLeftButton_Y_Action;
            }
        }

        /// <summary>
        /// 左手X键
        /// </summary>
        /// <param name="context"></param>
        private void OnMyLeftButton_X_Action(InputAction.CallbackContext context)
        {
            Debug.Log("按下左手X键--------------------");
        }
        /// <summary>
        /// 左手Y键
        /// </summary>
        /// <param name="context"></param>
        private void OnMyLeftButton_Y_Action(InputAction.CallbackContext context)
        {
            Debug.Log("按下左手Y键--------------------");
        }


        /// <summary>
        /// 右手X键
        /// </summary>
        /// <param name="context"></param>
        private void OnMyRightButton_X_Action(InputAction.CallbackContext context)
        {
            Debug.Log("按下右手A键--------------------");
        }
        /// <summary>
        /// 右手Y键
        /// </summary>
        /// <param name="context"></param>
        private void OnMyRightButton_Y_Action(InputAction.CallbackContext context)
        {
            Debug.Log("按下右手B键--------------------");
        }

        static InputAction GetInputAction(InputActionReference actionReference)
        {
#pragma warning disable IDE0031 // Use null propagation -- Do not use for UnityEngine.Object types
            return actionReference != null ? actionReference.action : null;
#pragma warning restore IDE0031
        }
    }
}

总结

好记性不如烂笔头
