Monitor ini file changes and perform joint debugging in C# unity project, a beginner's guide

1. Unity creates a new empty object and attaches the script

2. The script is written as follows: Note that file monitoring needs to be executed in updata, and the class must be inherited from MonoBehaviour. This is because in the unity project, one is the start entrance Start(), and the other is a bit like window refresh. Of course, I don’t know if it is understood in this way. I am also a novice anyway a>

namespace FileWatchered
{
    public class IniFile
    {
        public string path; //INI文件名


        //声明读写INI文件的API函数
        [DllImport("kernel32")]
        private static extern long WritePrivateProfileString(string section, string key,
                    string val, string filePath);


        [DllImport("kernel32")]
        private static extern int GetPrivateProfileString(string section, string key, string def,
                    StringBuilder retVal, int size, string filePath);


        //类的构造函数，传递INI文件名
        public IniFile(string INIPath)
        {
            path = INIPath;
        }


        //写INI文件
        public void IniWriteValue(string Section, string Key, string Value)
        {
            WritePrivateProfileString(Section, Key, Value, this.path);
        }


        //读取INI文件指定
        public string IniReadValue(string Section, string Key)
        {
            StringBuilder temp = new StringBuilder(255);
            int i = GetPrivateProfileString(Section, Key, "", temp, 255, this.path);
            return temp.ToString();
        }
    }

3.vs Debugging》Attach the unity debugger and turn on the unity play, then you can perform joint debugging

4. Specify ini to see the effect. I wrote it hard. You can modify the path yourself.

F:/test/100.ini

[product]
type = 2
productId = 5
imageUrl=E:/9999.png

5. Do not set full screen when exporting exe from unity
