如何检测Oculus Quest 2控制器0.5秒内向玩家旋转30度

核心触发条件 #

• 控制器绕自身轴向玩家方向旋转累计≥30度
• 完成该旋转的时间≥0.5秒
• 两个条件需同时满足，角度不足或用时短于0.5秒均不触发

代码实现 #

基于Unity Input System，结合你已定义的InputActionProperty变量，实现如下：

using UnityEngine;
using UnityEngine.InputSystem;
using System.Collections.Generic;

public class ControllerRotationDetector : MonoBehaviour
{
    // 你已定义的控制器旋转输入
    [SerializeField] private InputActionProperty _rightRotationAction;
    [SerializeField] private InputActionProperty _leftRotationAction;

    // 检测参数配置
    [SerializeField] private float requiredRotationAngle = 30f;
    [SerializeField] private float minRequiredTime = 0.5f;
    [SerializeField] private ControllerSide targetController = ControllerSide.Right;

    // 存储旋转历史（旋转值+时间戳）
    private Queue<(Quaternion rotation, float timestamp)> _rotationHistory = new Queue<(Quaternion, float)>();
    private bool _isDetected = false;

    private enum ControllerSide
    {
        Left,
        Right
    }

    private void Update()
    {
        if (_isDetected) return;

        // 获取当前控制器旋转值
        Quaternion currentRotation = targetController == ControllerSide.Right 
            ? _rightRotationAction.action.ReadValue<Quaternion>() 
            : _leftRotationAction.action.ReadValue<Quaternion>();
        float currentTime = Time.time;

        _rotationHistory.Enqueue((currentRotation, currentTime));

        // 清理超时历史并检测触发条件
        while (_rotationHistory.Count > 0 && currentTime - _rotationHistory.Peek().timestamp > minRequiredTime)
        {
            var startRecord = _rotationHistory.Peek();
            float angleDelta = CalculateRotationTowardsPlayer(startRecord.rotation, currentRotation);

            if (angleDelta >= requiredRotationAngle && currentTime - startRecord.timestamp >= minRequiredTime)
            {
                TriggerDetection();
                break;
            }

            _rotationHistory.Dequeue();
        }
    }

    // 计算控制器朝向玩家的有效旋转角度差
    private float CalculateRotationTowardsPlayer(Quaternion startRot, Quaternion endRot)
    {
        Vector3 playerForward = Camera.main.transform.forward;
        Quaternion startToPlayer = Quaternion.FromToRotation(startRot * Vector3.forward, playerForward);
        Quaternion endToPlayer = Quaternion.FromToRotation(endRot * Vector3.forward, playerForward);

        float startYaw = startToPlayer.eulerAngles.y;
        float endYaw = endToPlayer.eulerAngles.y;
        float angleDelta = Mathf.DeltaAngle(startYaw, endYaw);

        // 仅统计朝向玩家的正向旋转
        return angleDelta > 0 ? angleDelta : 0f;
    }

    // 触发检测后的逻辑
    private void TriggerDetection()
    {
        _isDetected = true;
        Debug.Log("控制器旋转检测触发！");
        // 此处添加自定义触发逻辑
        // 如需重复检测，执行完逻辑后重置_isDetected为false即可
    }

    // 重置检测状态（可选）
    public void ResetDetection()
    {
        _isDetected = false;
        _rotationHistory.Clear();
    }
}

关键说明 #

• 旋转有效性过滤：仅统计控制器朝向玩家的正向旋转，排除反向旋转的干扰
• 时间窗口管控：用队列存储历史旋转数据，实时清理超出0.5秒的记录，确保只检测符合时间要求的旋转过程
• 参数灵活调整：可通过Inspector面板修改旋转角度阈值、最小用时以及目标检测控制器
