Unity（四十三）：存档、文本文件读写

PlayerPrefs（运行模式）

using UnityEngine;namespace Example_01.Scripts
{public class GameArchives : MonoBehaviour{public string key;public string nickName = "PLee";public int age = 25;public float height = 1.71f;private void OnGUI(){GUILayoutOption[] options ={GUILayout.Width(300),};GUILayout.Label("【PlayerPrefs】");GUILayout.Label("键:");key = GUILayout.TextField(key, 10, options);GUILayout.Label("昵称:");nickName = GUILayout.TextField(nickName, 10, options);GUILayout.Label($"年龄: {age}");age = (int)GUILayout.HorizontalSlider(age, 0, 100, options);GUILayout.Label($"身高: {height}");height = GUILayout.HorizontalSlider(height, 1, 2, options);// 存档if (GUILayout.Button("存档")){PlayerPrefs.SetString("NickName", nickName);PlayerPrefs.SetInt("Age", age);PlayerPrefs.SetFloat("Height", height);Debug.Log("已存档");}// 强制保存数据if (GUILayout.Button("强制保存数据")){PlayerPrefs.SetString("NickName", nickName);PlayerPrefs.SetInt("Age", age);PlayerPrefs.SetFloat("Height", height);PlayerPrefs.Save(); // 强制保存数据Debug.Log("强制保存数据");}// 读档if (GUILayout.Button("读档"))Debug.Log($"{PlayerPrefs.GetString("NickName")} ---> {PlayerPrefs.GetInt("Age")} ---> {PlayerPrefs.GetFloat("Height")}");// 判断是否存在某个键if (GUILayout.Button("判断是否存在某个键")) Debug.Log(PlayerPrefs.HasKey(key) ? $"{key} 存在" : $"{key} 不存在");// 删除某个键if (GUILayout.Button("删档")) PlayerPrefs.DeleteKey(key);// 删除所有键if (GUILayout.Button("清空存档")) PlayerPrefs.DeleteAll();}}
}

EditorPrefs（编辑器模式）

using Example_01.Scripts;
using UnityEditor;
using UnityEngine;[CustomEditor(typeof(GameArchives))]
public class GameArchivesEditor : Editor
{public override void OnInspectorGUI(){GUILayout.Label("【PlayerPrefs】");base.OnInspectorGUI();GUILayout.Label("【EditorPrefs】");GameArchives script = target as GameArchives;// 存档if (GUILayout.Button("存档")){EditorPrefs.SetString("NickName", script!.nickName);EditorPrefs.SetInt("Age", script.age);EditorPrefs.SetFloat("Height", script.height);Debug.Log("已存档");}// 读档if (GUILayout.Button("读档"))Debug.Log($"{EditorPrefs.GetString("NickName")} ---> {EditorPrefs.GetInt("Age")} ---> {EditorPrefs.GetFloat("Height")}");// 判断是否存在某个键if (GUILayout.Button("判断是否存在某个键")) Debug.Log(EditorPrefs.HasKey(script!.key) ? $"{script.key} 存在" : $"{script.key} 不存在");// 删除某个键if (GUILayout.Button("删档")) EditorPrefs.DeleteKey(script!.key); // 删除所有键if (GUILayout.Button("清空存档")) EditorPrefs.DeleteAll(); }
}

文本文件读写

编辑器模式

public class ReadWriteTextFileEditor
{[MenuItem("Tools/Read & Write File")]public static void ReadWriteText(){string path = Path.Combine(Application.dataPath, "test.txt");if(File.Exists(path)) File.Delete(path);StringBuilder sb = new StringBuilder();sb.Append("Prosper").AppendLine();sb.Append("Lee").AppendLine();File.WriteAllText(path, sb.ToString());AssetDatabase.Refresh();Debug.Log(File.ReadAllText(path));}
}

运行模式

public class ReadWriteTextFile : MonoBehaviour
{private void Start(){// 可读不可写string resourcesText = Resources.Load<TextAsset>("test").text;Debug.Log($"可读不可写 ---> {resourcesText}");// 可读不可写Debug.Log(Application.streamingAssetsPath); // [Project]/Assets/StreamingAssetsstring path1 = Path.Combine(Application.streamingAssetsPath, "test.txt");string streamingAssetsText = File.ReadAllText(path1);Debug.Log($"可读不可写 ---> {streamingAssetsText}");// 可读可写Debug.Log(Application.persistentDataPath); // C:/Users/[username]/AppData/LocalLow/DefaultCompany/Unity-Example-Demostring path2 = Path.Combine(Application.persistentDataPath, "test.txt");File.WriteAllText(path2, DateTime.Now.ToString(CultureInfo.InvariantCulture));string persistentDataText = File.ReadAllText(path2);Debug.Log($"可读可写 ---> {persistentDataText}");}private void OnGUI(){#if UNITY_EDITORif (GUILayout.Button("打开文件夹")) EditorUtility.RevealInFinder(Application.persistentDataPath);#endif}
}
