Unity Editor knowledge point finishing (ScriptableObject)

Create a template

[System.Serializable]//类可以序列化
public class LevelSettings : ScriptableObject
 {
    
    
     public float TotalTime = 60;
     public float Gravity = -30;
     public AudioClip Bgm ;
     public Sprite Background;
 }

Declare a method to create an instance in the utility class

/// <summary>
/// 创建ScriptableObject类型的实例子
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="path">保存路径</param>
/// <returns></returns>
public static T CreateAsset<T>(string path) where T : ScriptableObject
{
    
    
    //创建内存中T类型实例
    T dataClass = ScriptableObject.CreateInstance<T>();

    //根据上方的实例创建资源
    AssetDatabase.CreateAsset(dataClass, path);

    //刷新project
    AssetDatabase.Refresh();

    //保存
    AssetDatabase.SaveAssets();

    return dataClass;

}

Add the corresponding button in the Editor menu bar

[MenuItem("Tools/Level Creator/New Level Settings")]
private static void NewLevelSettings()
{
    
    
    //弹出保存文件对话框
    //参数 title，资源默认名称 扩展名 窗体显示主要内容
    //返回 string 存储目录
    string path = EditorUtility.SaveFilePanelInProject("New Level Settings", "LevelSettings", "asset", "Define the name for the LevelSettings asset.");

    //判断路径是否为空
    if (!string.IsNullOrEmpty(path))
    {
    
    
        //创建实例
        EditorUtils.CreateAsset<LevelSettings>(path);
    }
}
