美好的一天。我在使用与arduino的统一性时遇到问题，我在使用串行端口作为与arduino的统一通信方式。我只是将字符串从统一发送到arduino。
第一个玩家转入IOException之后：是否发生访问被拒绝？我无法玩第二个回合，因为第一回合后团结停止了。 然后抛出IOException：访问被拒绝
统一码
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
using System.IO.Ports;
public class SceneManagement : MonoBehaviour
{
SerialPort sp = new SerialPort("COM3", 9600);
// Use this for initialization
public void CountPlayer()
{
SceneManager.LoadScene("CountPlayer");
}
public void RandomSubject()
{
SceneManager.LoadScene("RandomSubject");
}
public void Game()
{
if (!sp.IsOpen)
{
sp.Open();
sp.WriteTimeout = 100;
Debug.Log("Port successfully opened");
}
sp.Write("green");
SceneManager.LoadScene("Game1");
}
}
上面的代码是要执行的文件，它将向arduino发送“绿色”字符串

答案 0 :(得分：1)
一次只有一个进程可以使用特定的串行端口。
COM3已由 SceneManagement 打开，因此当其他人要求访问COM3时，将拒绝访问。
使用管理器类来处理SerialPort对象，或仅调用
GetComponent<SceneManagement>().GetSP()
在其他脚本中获取现有的串行端口。
