1. Switchable v2

改了這兩個
TPSCharacterAnimationController.Mode
TPSCharacterLocomotionController.Mode
之后我就覺得，有很多是重復的，是可以改的

比如

public float ModeTransitionTime = 1f;private List<ISwitchable> switchableObjectList = new List<ISwitchable>();private Coroutine switchValueCoroutine;private void ClearSwitchableList()private IEnumerator ModeTransition(TPSCharacterBehaviourMode mode)

SwitchObject 也有很多重復的，我就做成了泛型 SwitchableGeneric<T>
SmoothDamp 沒有泛型，所以只好繼承泛型確定類型 SwitchableFloat SwitchableVector3
為了方便，承擔平滑插值邏輯的函數做成接口，并放到 SwitchableGeneric<T> 中，在 SwitchableFloat SwitchableVector3 中延遲實現

原來直接在 mono 里面做的協程，現在我把 Mode 單獨做成一個 Switcher 類，那么他就需要獲取到 mono 組件
原來直接在 mono 里面把 ISwitchable 加入一個列表，現在我把這個列表放到 Switcher 類中，于是 ISwitchable 需要有一個時機加入 Switcher 類的列表中
本來我是想在構造函數中做這些事的，但是首先我不能設置一個有參的構造函數，因為我必須要有一個無參的構造函數，才能在變量初始化的同時構造變量（如果有參，這個參數不能是編譯期提供的，所以我只能在 Awake 中調用有參構造函數），這樣我才能在監視器中配置類
所以 Switcher 有一個 RegisterSwitchable 函數來把 ISwitchable 加入一個列表，有 Owner 屬性配置 mono 主人，Switcher 的 Mode 的 setter 會觸發平滑協程，平滑協程里面對 ISwitchable 列表調用平滑函數

1.1 ISwitchable

1.3 SwitchableGeneric

要推遲接口的實現，所以使用抽象類

Assets/MeowFramework/Core/Switchable/SwitchableGeneric.cs

// ---------------------------------------------- // 作者: 廉價喵 // 創建于: 22/04/2022 18:55 // 最后一次修改于: 22/04/2022 21:33 // 版權所有: CheapMeowStudio // 描述: // ----------------------------------------------using System; using System.Collections.Generic; using Sirenix.OdinInspector; using UnityEngine;namespace MeowFramework.Core.Switchable {public abstract class SwitchableGeneric<T> : ISwitchable{/// <summary>/// 當前值/// </summary>[ShowInInspector][Tooltip("當前值")]protected T value;/// <summary>/// 當前值/// </summary>public T Value{get => value;set{AfterValueChangeAction?.Invoke(this.value, value);this.value = value;}}/// <summary>/// 值改變后觸發的委托/// </summary>[HideInInspector]public Action<T, T> AfterValueChangeAction;/// <summary>/// 預設值字典/// </summary>[Tooltip("預設值字典")]public Dictionary<Enum, T> TargetValueDict = new Dictionary<Enum, T>();// 緩存/// <summary>/// 平滑速度/// </summary>protected T smoothVelocity;/// <summary>/// 平滑時間/// </summary>[Tooltip("平滑時間")]public float SmoothTime = 0.2f;// 析構函數~SwitchableGeneric(){AfterValueChangeAction = null;}// 接口// 延遲實現接口/// <summary>/// 使變量在不同預設值之間切換/// </summary>/// <param name="mode">預設模式</param>public abstract void SwitchValue(Enum mode);} }

1.4 SwitchableFloat

1.5 SwitcherEnum

Assets/MeowFramework/Core/Switchable/SwitcherEnum.cs

// ---------------------------------------------- // 作者: 廉價喵 // 創建于: 22/04/2022 18:45 // 最后一次修改于: 22/04/2022 20:38 // 版權所有: CheapMeowStudio // 描述: // ----------------------------------------------using System; using System.Collections; using System.Collections.Generic; using System.Linq; using Sirenix.OdinInspector; using UnityEngine;namespace MeowFramework.Core.Switchable {public class SwitcherEnum<T> : ISwitcher where T: Enum{/// <summary>/// 主人/// </summary>private SerializedMonoBehaviour owner;/// <summary>/// 主人/// </summary>public SerializedMonoBehaviour Owner{set => owner = value;}/// <summary>/// 行動模式/// </summary>[ShowInInspector][Tooltip("行動模式")]private T mode;/// <summary>/// 行動模式/// </summary>public T Mode{get => mode;set{if (owner != null){if (switchValueCoroutine != null)owner.StopCoroutine(switchValueCoroutine);switchValueCoroutine = owner.StartCoroutine(ModeTransition(value));mode = value;}}}/// <summary>/// 切換模式的過渡時間/// </summary>[Tooltip("切換模式的過渡時間")]public float ModeTransitionTime = 1f;// 緩存/// <summary>/// 可切換變量列表/// </summary>private List<ISwitchable> switchableObjectList = new List<ISwitchable>();/// <summary>/// 切換變量的協程/// </summary>private Coroutine switchValueCoroutine;/// <summary>/// 模式過渡：使變量在不同預設值之間切換/// </summary>/// <param name="mode">預設模式</param>/// <returns></returns>private IEnumerator ModeTransition(T mode){float time = ModeTransitionTime;while(time > 0){time -= Time.deltaTime;foreach (ISwitchable switchable in switchableObjectList){switchable.SwitchValue(mode);}}yield return null;}/// <summary>/// 注冊可切換變量/// </summary>/// <param name="switchable">可切換變量</param>public void RegisterSwitchable(ISwitchable switchable){if(switchable != null)switchableObjectList.Add(switchable);}/// <summary>/// 注冊可切換變量/// </summary>/// <param name="switchableList">可切換變量列表</param>public void RegisterSwitchable(List<ISwitchable> switchableList){if (switchableList != null)switchableObjectList.AddRange(switchableList);}} }

效果大概是這樣
跟以前看上去一樣hhh

之后應該是 Controller 改動后的代碼
但是我測試的時候又發現了問題，所以先解決 Switchable 的 Bug……

2. Bug：構造期間不為 null 游戲開始后變成 null

測試的時候發現 SwitcherMode.switchableObjectList == null 導致 InitSwitchableList() 中 switchableObjectList.AddRange(switchableList); 出錯

解決方法記錄：

[Unity][Odin Inspector] SerializedMonoBehaviour 中的 private List 會被初始化為 null

3. Switchable v3

3.1 SwitcherEnum v3.1

既然 SerializedMonoBehaviour 中的 private List 會被初始化為 null
那我就只能在其它函數里面檢查 null，如果為 null 就代為初始化

Assets/MeowFramework/Core/Switchable/SwitcherEnum.cs

// ---------------------------------------------- // 作者: 廉價喵 // 創建于: 22/04/2022 18:45 // 最后一次修改于: 26/04/2022 9:30 // 版權所有: CheapMeowStudio // 描述: // ----------------------------------------------using System; using System.Collections; using System.Collections.Generic; using System.Linq; using Sirenix.OdinInspector; using UnityEngine;namespace MeowFramework.Core.Switchable {public class SwitcherEnum<T> : ISwitcher where T: Enum{/// <summary>/// 主人/// </summary>private SerializedMonoBehaviour owner;/// <summary>/// 主人/// </summary>public SerializedMonoBehaviour Owner{set => owner = value;}/// <summary>/// 行動模式/// </summary>[ShowInInspector][Tooltip("行動模式")]private T mode;/// <summary>/// 行動模式/// </summary>public T Mode{get => mode;set{if (owner != null){if (switchValueCoroutine != null)owner.StopCoroutine(switchValueCoroutine);switchValueCoroutine = owner.StartCoroutine(ModeTransition(value));mode = value;}}}/// <summary>/// 切換模式的過渡時間/// </summary>[Tooltip("切換模式的過渡時間")]public float ModeTransitionTime = 1f;// 緩存/// <summary>/// 可切換變量列表/// </summary>private List<ISwitchable> switchableList = new List<ISwitchable>();/// <summary>/// 切換變量的協程/// </summary>private Coroutine switchValueCoroutine;/// <summary>/// 模式過渡：使變量在不同預設值之間切換/// </summary>/// <param name="mode">預設模式</param>/// <returns></returns>private IEnumerator ModeTransition(T mode){float time = ModeTransitionTime;while(time > 0){time -= Time.deltaTime;foreach (ISwitchable switchable in switchableList){switchable.SwitchValue(mode);}}yield return null;}/// <summary>/// 注冊可切換變量/// </summary>/// <param name="switchable">可切換變量</param>public void RegisterSwitchable(ISwitchable switchable){if (switchable == null)return;if (switchableList == null)switchableList = new List<ISwitchable> {switchable};elseswitchableList.Add(switchable);}/// <summary>/// 注冊可切換變量/// </summary>/// <param name="switchableList">可切換變量列表</param>public void RegisterSwitchable(List<ISwitchable> switchableList){if (switchableList == null)return;if (this.switchableList == null)this.switchableList = switchableList;elsethis.switchableList.AddRange(switchableList);}} }

測試過這樣是沒有問題的
但是如果真的要這么寫的話，那還不如直接寫成一個屬性

3.2 ISwitcher v3.2

Assets/MeowFramework/Core/Switchable/ISwitcher.cs

// ---------------------------------------------- // 作者: 廉價喵 // 創建于: 22/04/2022 19:08 // 最后一次修改于: 26/04/2022 9:37 // 版權所有: CheapMeowStudio // 描述: // ----------------------------------------------using System.Collections.Generic;namespace MeowFramework.Core.Switchable {/// <summary>/// 切換器的借口/// </summary>public interface ISwitcher{/// <summary>/// 可切換變量列表/// </summary>public List<ISwitchable> SwitchableList{get;}} }

3.3 SwitcherEnum v3.2

這樣，接下來就可以放 Controller 了

3.4 TPSCharacterUIController.Mode
