}

六、接口

1、实例

// 定义一个名为 IKitchenObjectParent 的接口
public interface IKitchenObjectParent
{Transform GetKitchenObjectFollowTransform();
}
// 实现接口的类
public class Player : MonoBehaviour, IKitchenObjectParent
{public Transform counterToPoint;// GetKitchenObjectFollowTransform 方法的具体实现public Transform GetKitchenObjectFollowTransform(){return counterToPoint;}
}
// 实现接口的类
public class BaseCounter : MonoBehaviour, IKitchenObjectParent
{public Transform stove;// GetKitchenObjectFollowTransform 方法的具体实现public Transform GetKitchenObjectFollowTransform(){return stove;}
}

在上面的示例中，首先定义了一个名为 IKitchenObjectParent 的接口，它包含了一个名为 GetKitchenObjectFollowTransform 的方法，该方法返回一个 Transform 对象。

接下来，Player 和 BaseCounter 类都实现了 IKitchenObjectParent 接口，并分别提供了它们自己的 GetKitchenObjectFollowTransform 方法的具体实现。在 Player 类中，counterToPoint 是一个 Transform 类型的属性，它被用作返回值。而在 BaseCounter 类中，stove 是另一个 Transform 类型的属性，它被用作返回值。

通过这种方式，在其他地方使用 IKitchenObjectParent 接口的实例时，可以使用 Player 或 BaseCounter 类的实例，并调用 GetKitchenObjectFollowTransform 方法来获取不同的厨房对象的跟随位置（根据具体的实现类）。这样可以实现代码的灵活性和可扩展性。

2、接口脚本的一些规则

使用 interface 关键字定义接口。例如：public interface IKitchenObjectParent { }
接口的命名应尽量清晰明了，表达出接口的用途和功能。
方法的声明只包含方法名、参数列表和返回类型，不包含方法的具体实现。
方法的返回类型可以是任意合法的数据类型，也可以是其他接口或类的类型。
接口中的方法通常不应包含访问修饰符，因为接口中定义的方法默认为公共（public）。
接口中可以包含属性、事件和索引器等成员，但通常应尽量保持接口的简洁和清晰。接口的目的是定义一组行为，而不是状态。
接口可以继承其他接口，使用冒号（:）来表示接口之间的继承关系。例如：public interface IChildInterface : IParentInterface { }
类可以实现一个或多个接口，使用冒号（:）来表示实现的接口。例如：public class MyClass : IInterface1, IInterface2 { }
实现接口的类必须提供接口中的所有成员的具体实现，包括方法、属性和事件等。
实现接口的类可以选择性地添加其他成员，但在使用接口的实例时，只能访问接口中定义的成员。

3、实现接口的类：在Unity中实现接口的类遵循以下规则：

使用关键字 : MonoBehaviour 或 : ScriptableObject 标记类继承自 MonoBehaviour 或 ScriptableObject，这是Unity中常用的基类。例如：

public class MyClass : MonoBehaviour, MyInterface {// 类的实现代码
}

或

public class MyClass : ScriptableObject, MyInterface {// 类的实现代码
}

实现接口的类必须实现接口中定义的所有方法，包括事件的处理方法。
可以选择性地覆盖接口中定义的默认方法。
可以实现多个接口，只需使用逗号将接口名称分隔开。例如：

public class MyClass : MonoBehaviour, IInterface1, IInterface2 {// 类的实现代码
}

七、拿起和放下物品

1、定义厨房物品的父对象（厨柜）的行为：新建 IkitchenObjectParent.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public interface IkitchenObjectParent 
{public Transform GetKitchenObjectFollowTransform();public void SetKitchenObject(KitchenObject kitchenObject);public KitchenObject GetKitchenObject();public void ClearKitchenObject();public bool HasKitchenObject();
}

}

3、编辑ClearCounter.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class ClearCounter : MonoBehaviour,IkitchenObjectParent
{[SerializeField] private KitchenObjectSO kitchenObjectSO;[SerializeField] private Transform counterToPoint;[SerializeField] private ClearCounter secondClearCounter;[SerializeField] private bool testing;private KitchenObject kitchenObject;private void Update(){if (testing && Input.GetKeyDown(KeyCode.T)){if (kitchenObject != null){kitchenObject.SetKitchenObjectParent(secondClearCounter);}}}public void Interact(Player player){if (kitchenObject == null){Transform kitchObjectTransform = Instantiate(kitchenObjectSO.prefab, counterToPoint);kitchObjectTransform.GetComponent<KitchenObject>().SetKitchenObjectParent(this);}else{//kitchenObject.SetKitchenObjectParent(secondClearCounter)//Debug.Log(kitchenObject.GetKitchenObjectParent());}}public Transform GetKitchenObjectFollowTransform(){return counterToPoint;}public void SetKitchenObject(KitchenObject kitchenObject){this.kitchenObject = kitchenObject;}public KitchenObject GetKitchenObject(){return kitchenObject;}public void ClearKitchenObject(){kitchenObject = null;}public bool HasKitchenObject(){return kitchenObject != null;}
}

5、编辑Player预制体

Create Empty，命名为KitchenObjectHoldPoint，做为Player的子物体;

6、编辑Player.cs

}

(7) 赋值

三、增加柜台

1、放置第三个柜台

2、放置第四个柜台

委托事件

一、委托事件相关知识

编写 C# 中的 Unity 项目时，需要实现自定义事件，可通过委托事件实现。

（一）委托事件的实例

例如（假设 OnButtonClick 是当前类 MyClass 中的一个事件，且在该类的某个方法中订阅该事件）

public class MyClass
{//委托类型public delegate void ButtonClickEventHandler(object sender, EventArgs e);//声明委托事件public event ButtonClickEventHandler OnButtonClick;public void SubscribeToEvent(){// 订阅事件this.OnButtonClick += HandleButtonClick;}// 事件处理程序public void HandleButtonClick(object sender, EventArgs e){// 点击时出现的行为Console.WriteLine("Button was clicked!");}// 触发事件的方法（当调用 ClickButton()方法时，检查是否有订阅，如果有，则触发事件，同时运行事件处理程序）public void ClickButton(){// 如果OnButtonClick不是null（即有订阅者），则触发事件OnButtonClick?.Invoke(this, EventArgs.Empty);}
}

（二）委托事件的组成：

1. 委托类型：

(1) 含义：用于定义事件的签名，本身并不会直接起作用，它只是定义了一个委托类型

(2) 实例

类似于一个方法的原型，指定了事件处理程序应该具有的返回类型和参数类型，如：

(3) 解析

delegate ：委托关键字，在C#中用于创建委托类型。

委托是一种类型安全的函数指针，可以用来引用一个或多个方法。

ButtonClickEventHandler: 委托的名称，可根据需要自定义。

(object sender, EventArgs e): 委托的参数列表（委托类型的签名）。

这个委托期望两个参数，一个是触发事件的对象，另一个是事件的参数。

sender参数通常是发送事件的对象本身，EventArgs是事件参数的基类。

object sender 表示事件的发送者，EventArgs e 表示事件参数。

(4) 作用

这段代码定义了一个委托类型ButtonClickEventHandler，用于定义按钮点击事件的处理方法。

委托类型可以用来创建具有相同签名的方法的实例，以便在事件被触发时调用。

(5) 注意：

使用一个现有的委托类型时，无需自己定义委托类型。例如（直接声明委托事件）

//声明一个名为 OnSelectedCounterChanged 的事件
public event EventHandler<OnSelectedCounterChangedEventArgs> OnSelectedCounterChanged;
//定义委托事件的参数(使用EventArgs传递选中的柜台信息)
public class OnSelectedCounterChangedEventArgs : EventArgs
{//注意，属性命名时首字母是大写（图片上写错了）public BaseCounter SelectedCounter;
}

EventHandler<OnSelectedCounterChangedEventArgs>是 .NET Framework 中的一个通用委托类型

EvenHandler<TEventArgs> 是一个预定义的委托类型，用于处理事件并传递自定义参数(TEventArgs)

它的签名类似于 void SomeMethod(object sender, TEventArgs e)，其中 sender 表示事件的发送者，e 是传递给事件处理程序的参数。

(6) 使用

当需要定义一个按钮点击事件的处理方法时，可以使用此委托类型来声明一个委托实例，并将其绑定到按钮的点击事件上。当按钮被点击时，委托实例所引用的方法将被调用。

2. 事件声明：用于定义一个事件成员。

它与字段的声明类似，但以 `event` 关键字开头，后面跟着委托类型和事件的名称。如：

public event ButtonClickEventHandler OnButtonClick;

再如：

// 定义委托事件的参数
public class OnselectedCounterChangedEventArgs : EventArgs
{//定义一个名为 selectedCounter 的属性，它存储了被选中柜子的相关信息public BaseCounter selectedCounter;
}
// 声明一个名为 OnSelectedCounterChanged 的事件
// 在触发OnSelectedCounterChanged事件时，将选中柜子作为参数传递给事件的订阅者（事件处理方法）。
// 事件的订阅者可以根据选中柜子的信息来进行相应的处理
public event EventHandler<OnselectedCounterChangedEventArgs> OnSelectedCounterChanged;

3. 事件处理程序

(1) 事件处理程序是一个方法，用于响应事件的发生。它必须与委托类型的签名匹配。例如：

public void HandleButtonClick(object sender, EventArgs e)
{// 点击时发生的行为
}

(2) 实例

private void Instance_OnSelectedCounterChanged(object sender, Player.OnSelectedCounterChangedEventArgs e)
{if(e.selectedCounter == baseCounter){Show();}else{Hide();}
}

4. 订阅事件：

(1) 将一个方法与事件关联起来，当事件触发时，关联的方法被调用。例如：

Button button = new Button();
button.OnButtonClick += HandleButtonClick; // 订阅事件

(2) 实例

// 订阅事件
gameInput.OnInteractAction += GameInput_OnInteractAction;
// 事件处理程序
private void GameInput_OnInteractAction(object sender, System.EventArgs e)
{if(selectedCounter!=null){selectedCounter.Interact(this);}
}

+= 运算符用于将事件处理程序（Event Handler）添加到事件中。

当OnInteractAction事件被触发时，添加到这个事件的所有处理程序都会被执行

将GameInput_OnInteractAction方法注册为gameInput对象的OnInteractAction事件的一个事件处理程序。

当OnInteractAction事件被触发（比如玩家进行了一个交互动作），GameInput_OnInteractAction方法就会被执行，从而进行相应的处理。

5. 触发事件

(1) 在事件发生时调用事件委托来通知所有的订阅者，让它们执行关联的方法。例如：

public void ClickButton()
{// 触发点击事件OnButtonClick?.Invoke(this, EventArgs.Empty);
}

(2) 在其它方法中，调用ClickButton()时，就会触发OnButtonClick事件，检查是否有订阅者，如果有订阅者，则执行事件处理程序

（三）委托事件的应用

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class Player : MonoBehaviour
{//定义委托事件的参数(使用EventArgs传递选中的柜台信息)public class OnSelectedCounterChangedEventArgs : EventArgs{public BaseCounter SelectedCounter;}//声明一个名为 OnSelectedCounterChanged 的事件public event EventHandler<OnSelectedCounterChangedEventArgs> OnSelectedCounterChanged;private BaseCounter selectedCounter;private void HandleInteractions(){SetSelectedCouter(baseCounter);}//触发事件（当该方法被调用时，触发OnSelectedCounterChanged事件）private void SetSelectedCouter(BaseCounter selectedCounter){this.selectedCounter = selectedCounter;OnSelectedCounterChanged?.Invoke(this, new OnSelectedCounterChangedEventArgs{SelectedCounter = selectedCounter});}
}

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class SelectedCounterVisual : MonoBehaviour
{// 订阅事件private void Start(){Player.Instance.OnSelectedCounterChanged += Instance_OnSelectedCounterChanged;}// 事件处理程序private void Instance_OnSelectedCounterChanged(object sender, Player.OnSelectedCounterChangedEventArgs e){if(e.SelectedCounter == baseCounter){Show();}else{Hide();}}
}

执行顺序

当运行HandleInteractions()程序时，启动SetSelectedCouter()，向订阅者SelectedCounterVisual中的Start()传递两个信息，从而启动事件处理程序Instance_OnSelectedCounterChanged()；

二、设置委托事件

1、新建BaseCounter.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class BaseCounter : MonoBehaviour
{public virtual void Interact(Player player){Debug.LogError("BaseCounter.Interact();");}
}

2、编辑ClearCounter.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class ClearCounter : BaseCounter,IkitchenObjectParent{……}//重写public override void Interact(Player player){if (kitchenObject == null){Transform kitchObjectTransform = Instantiate(kitchenObjectSO.prefab, counterToPoint);kitchObjectTransform.GetComponent<KitchenObject>().SetKitchenObjectParent(this);}else{kitchenObject.SetKitchenObjectParent(player);}}

3、编辑ContainerCounter.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class ContainerCounter : BaseCounter,IkitchenObjectParent
{public override void Interact(Player player){if (kitchenObject == null){Transform kitchObjectTransform = Instantiate(kitchenObjectSO.prefab, counterToPoint);kitchObjectTransform.GetComponent<KitchenObject>().SetKitchenObjectParent(this);}else{kitchenObject.SetKitchenObjectParent(player);}}
}

4、编辑Player.cs，重命名为baseCounter

using System;
using System.Collections;

}

5、编辑SelectedCounterVisual.cs

(1) 重命名为baseCounter

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class SelectedCounterVisual : MonoBehaviour
{[SerializeField] private BaseCounter baseCounter;[SerializeField] private GameObject[] visualGameObjectArray;private void Start(){Player.Instance.OnSelectedCounterChanged += Player_OnSelectedCounterChanged;}private void Player_OnSelectedCounterChanged(object sender, Player.OnselectedCounterChangedEventArgs e){if (e.selectedCounter == baseCounter){Show();}else{Hide();}}private void Show(){foreach (GameObject visualGameObject in visualGameObjectArray){visualGameObject.SetActive(true);}}private void Hide(){foreach (GameObject visualGameObject in visualGameObjectArray){visualGameObject.SetActive(false);}}
}

(2) 编辑 ContainerCounter预制体（赋值）

(3) 删除Single door的子物体 ObjectSprite

6、编辑ClearCounter预制体

重构代码

一、初步调整

1、给基类 BaseCounter.cs 增加并设置接口，注意声明

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class BaseCounter : MonoBehaviour,IkitchenObjectParent
{[SerializeField] private Transform counterToPoint;//这个成员可以被该类本身、同一个包中的其他类以及该类的所有子类（无论子类是否在同一个包中）访问protected KitchenObject kitchenObject;public virtual void Interact(Player player){Debug.LogError("BaseCounter.Interact();");}public Transform GetKitchenObjectFollowTransform(){return counterToPoint;}public void SetKitchenObject(KitchenObject kitchenObject){this.kitchenObject = kitchenObject;}public KitchenObject GetKitchenObject(){return kitchenObject;}public void ClearKitchenObject(){kitchenObject = null;}public bool HasKitchenObject(){return kitchenObject != null;}
}

2、给 BaseCounter.cs 的子类除去接口和相应的事件

(1) 编辑ContainerCounter.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class ContainerCounter : BaseCounter
{[SerializeField] private KitchenObjectSO kitchenObjectSO;public override void Interact(Player player){if (kitchenObject == null){Transform kitchObjectTransform = Instantiate(kitchenObjectSO.prefab, counterToPoint);kitchObjectTransform.GetComponent<KitchenObject>().SetKitchenObjectParent(this);}else{kitchenObject.SetKitchenObjectParent(player);}}
}

(2) 编辑ClearCounter.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class ClearCounter : BaseCounter
{[SerializeField] private KitchenObjectSO kitchenObjectSO;public override void Interact(Player player){if (kitchenObject == null){Transform kitchObjectTransform = Instantiate(kitchenObjectSO.prefab, counterToPoint);kitchObjectTransform.GetComponent<KitchenObject>().SetKitchenObjectParent(this);}else{kitchenObject.SetKitchenObjectParent(player);}}
}

二、重新整理

1、编辑 BaseCounter.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class BaseCounter : MonoBehaviour,IkitchenObjectParent
{[SerializeField] private Transform counterToPoint;//更改private KitchenObject kitchenObject;public virtual void Interact(Player player){Debug.LogError("BaseCounter.Interact();");}public Transform GetKitchenObjectFollowTransform(){return counterToPoint;}public void SetKitchenObject(KitchenObject kitchenObject){this.kitchenObject = kitchenObject;}public KitchenObject GetKitchenObject(){return kitchenObject;}public void ClearKitchenObject(){kitchenObject = null;}public bool HasKitchenObject(){return kitchenObject != null;}
}

2、编辑ContainerCounter.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class ContainerCounter : BaseCounter
{[SerializeField] private KitchenObjectSO kitchenObjectSO;public override void Interact(Player player){Transform kitchObjectTransform = Instantiate(kitchenObjectSO.prefab);kitchObjectTransform.GetComponent<KitchenObject>().SetKitchenObjectParent(player);}
}

3、编辑ClearCounter.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class ClearCounter : BaseCounter
{[SerializeField] private KitchenObjectSO kitchenObjectSO;public override void Interact(Player player){}
}

柜台动画

一、打开柜子，拿出物品

1、编辑ContainerCounter预制体，选择ContainerCounter_Visual，双击Animator组件中的ContainerCounter动画，出现动画界面

2、给ContainerCounter预制体的子物体ContainerCounter_Visual添加ContainerCounterVisual.cs组件

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class ContainerCounterVisual : MonoBehaviour
{private Animator animator;private void Awake(){animator = GetComponent<Animator>();}
}

3、编辑ContainerCounter.cs

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class ContainerCounter : BaseCounter
{public event EventHandler OnplayerGrabbedObject;//玩家抓取的对象上[SerializeField] private KitchenObjectSO kitchenObjectSO;public override void Interact(Player player){Transform kitchObjectTransform = Instantiate(kitchenObjectSO.prefab);kitchObjectTransform.GetComponent<KitchenObject>().SetKitchenObjectParent(player);OnplayerGrabbedObject?.Invoke(this,EventArgs.Empty);}
}

4、编辑 ContainerCounterVisual.cs并赋值

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class ContainerCounterVisual : MonoBehaviour
{private const string OPEN_CLOSE = "OpenClose";[SerializeField]private ContainerCounter containerCounter;private Animator animator;private void Awake(){animator = GetComponent<Animator>();}private void Start(){containerCounter.OnplayerGrabbedObject += ContainerCounter_OnplayerGrabbedObject;}private void ContainerCounter_OnplayerGrabbedObject(object sender, System.EventArgs e){animator.SetTrigger(OPEN_CLOSE);}
}

二、放下物品

1、编辑ClearCounter.cs：检查当前柜台是否是空柜台，如果是，检查玩家是否手持物品，如果是，物品放在空柜台上

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class ClearCounter : BaseCounter
{[SerializeField] private KitchenObjectSO kitchenObjectSO;public override void Interact(Player player){if (!HasKitchenObject()){//There is no KitchEnObject hereif (player.HasKitchenObject()){//Player is carrying somethingplayer.GetKitchenObject().SetKitchenObjectParent(this);}}else{//There is a KitchenObject here}}
}

2、测试：可见角色从储物柜拿出物品，放在空柜台上

3、将"KitchenObject"从柜台上取下，并将其交给玩家携带

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class ClearCounter : BaseCounter
{[SerializeField] private KitchenObjectSO kitchenObjectSO;public override void Interact(Player player){if (!HasKitchenObject()){//There is no KitchEnObject hereif (player.HasKitchenObject()){//Player is carrying somethingplayer.GetKitchenObject().SetKitchenObjectParent(this);}else{//Player not carrying anything}}else{//There is a KitchenObject hereif(player.HasKitchenObject()){//Player is carrying something}else{//Player is not carrying anythinbgGetKitchenObject().SetKitchenObjectParent(player);}}}
}

三、增加检查

1、编辑 ContainerCounterVisual.cs

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class ContainerCounter : BaseCounter
{public event EventHandler OnplayerGrabbedObject;//玩家抓取的对象上[SerializeField] private KitchenObjectSO kitchenObjectSO;public override void Interact(Player player){if (!player.HasKitchenObject()){Transform kitchObjectTransform = Instantiate(kitchenObjectSO.prefab);kitchObjectTransform.GetComponent<KitchenObject>().SetKitchenObjectParent(player);OnplayerGrabbedObject?.Invoke(this, EventArgs.Empty);}}
}

}

五、切割对象

1、食材综合处理

(1) 新建CuttingRecipeSO.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
[CreateAssetMenu()]
public class CuttingRecipeSO : ScriptableObject
{public KitchenObjectSO input;public KitchenObjectSO output;
}

(2) 在ScriptableObjects下新建 CuttingRecipeSO文件夹

(3) 在CuttingRecipeSO文件夹下创建CuttingRecipeSO对象，命名为Tomato-TomatoSilices

(4) 分别创建和设置CuttingRecipeSO对象：Cabbage-CabbageSlices、CheeseBlock-CheeseSlices

2、食材与食材切片一一对应

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class CuttingCounter : BaseCounter
{[SerializeField] private CuttingRecipeSO[] cuttingRecipeSOArray;public override void Interact(Player player){if (!HasKitchenObject()){//There is no KitchEnObject hereif (player.HasKitchenObject()){//Player is carrying somethingplayer.GetKitchenObject().SetKitchenObjectParent(this);}else{//Player not carrying anything}}else{//There is a KitchenObject hereif (player.HasKitchenObject()){//Player is carrying something}else{//Player is not carrying anythinbgGetKitchenObject().SetKitchenObjectParent(player);}}}public override void InteractAlternate(Player player){if (HasKitchenObject()){//There is a KitchenObject hereKitchenObjectSO outputKitchenObjectSO = GetOutputForInput(GetKitchenObject().GetKitchenObjectSO());GetKitchenObject().DestroySelf();KitchenObject.SpawnKitchenObject(outputKitchenObjectSO, this);}}private KitchenObjectSO GetOutputForInput(KitchenObjectSO inputKitchenObjectSO){foreach(CuttingRecipeSO cuttingRecipeSO in cuttingRecipeSOArray){if(cuttingRecipeSO.input == inputKitchenObjectSO){return cuttingRecipeSO.output;}}return null;}
}

(2) 赋值

3、处理一些细节（可能会报错的地方：非切割食材和食材再次切割设置无应答）

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class CuttingCounter : BaseCounter
{[SerializeField] private CuttingRecipeSO[] cuttingRecipeSOArray;public override void Interact(Player player){if (!HasKitchenObject()){//There is no KitchEnObject hereif (player.HasKitchenObject()){//Player is carrying somethingif (HasRecipeWithInput(player.GetKitchenObject().GetKitchenObjectSO())){//Player carrying something that can be cutplayer.GetKitchenObject().SetKitchenObjectParent(this);}}else{//Player not carrying anything}}else{//There is a KitchenObject hereif (player.HasKitchenObject()){//Player is carrying something}else{//Player is not carrying anythinbgGetKitchenObject().SetKitchenObjectParent(player);}}}public override void InteractAlternate(Player player){if (HasKitchenObject() && HasRecipeWithInput(GetKitchenObject().GetKitchenObjectSO())){//There is a KitchenObject here And it can be cutKitchenObjectSO outputKitchenObjectSO = GetOutputForInput(GetKitchenObject().GetKitchenObjectSO());GetKitchenObject().DestroySelf();KitchenObject.SpawnKitchenObject(outputKitchenObjectSO, this);}}private bool HasRecipeWithInput(KitchenObjectSO inputKitchenObjectSO){foreach (CuttingRecipeSO cuttingRecipeSO in cuttingRecipeSOArray){if (cuttingRecipeSO.input == inputKitchenObjectSO){return true;}}return false;}private KitchenObjectSO GetOutputForInput(KitchenObjectSO inputKitchenObjectSO){foreach (CuttingRecipeSO cuttingRecipeSO in cuttingRecipeSOArray){if (cuttingRecipeSO.input == inputKitchenObjectSO){return cuttingRecipeSO.output;}}return null;}
}

六、切菜进度条

1、增加最大切割进度

(1) 编辑CuttingRecipeSO.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
[CreateAssetMenu()]
public class CuttingRecipeSO : ScriptableObject
{public KitchenObjectSO input;public KitchenObjectSO output;// 最大切割进度public int cuttingProgressMax;
}

(2) 设置CuttingRecipeSO对象：打开ScriptableObjects/CuttingRecipeSO文件夹，设置cuttingProgressMax（另外两个为3，3，）

2、按F 3或 5 次后，切片成功：编辑CuttingCounter.cs

using System.Collections;

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;public class ProgressBarUI : MonoBehaviour
{[SerializeField] private CuttingCounter cuttingCounter;[SerializeField] private Image barImage;
}

(2) 赋值

6、添加委托事件

(1) 编辑 CuttingCounter.cs

using System;// 命名空间
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.EventSystems;public class CuttingCounter : BaseCounter
{// 委托事件public event EventHandler<OnprogressChangedEventArgs> OnProgressChanged;public class OnprogressChangedEventArgs : EventArgs{public float progressNormalized;}[SerializeField] private CuttingRecipeSO[] cuttingRecipeSOArray;private int cuttingProgress;public override void Interact(Player player){if (!HasKitchenObject()){// There is no KitchenObject hereif (player.HasKitchenObject()){// player is carrying somethingif (HasRecipeWithInput(player.GetKitchenObject().GetKitchenObjectSO())){// Player carrying something that can be cutplayer.GetKitchenObject().SetKitchenObjectParent(this);cuttingProgress = 0;// CuttingRecipeSO cuttingRecipeSO = GetCuttingRecipeSOWithInput(GetKitchenObject().GetKitchenObjectSO());OnProgressChanged?.Invoke(this, new OnprogressChangedEventArgs{progressNormalized = (float)cuttingProgress / cuttingRecipeSO.cuttingProgressMax});}}else{// Player not carrying anything}}else{// There is a KitchenObject hereif (player.HasKitchenObject()){// Player is carrying something}else{// Player is not carrying anythingGetKitchenObject().SetKitchenObjectParent(player);}}}public override void InteractAlternate(Player player){if (HasKitchenObject() && HasRecipeWithInput(GetKitchenObject().GetKitchenObjectSO())){// There is a KitchenObject her and it can be cutcuttingProgress++;CuttingRecipeSO cuttingRecipeSO = GetCuttingRecipeSOWithInput(GetKitchenObject().GetKitchenObjectSO());// OnProgressChanged?.Invoke(this, new OnprogressChangedEventArgs{progressNormalized = (float)cuttingProgress / cuttingRecipeSO.cuttingProgressMax});if (cuttingProgress >= cuttingRecipeSO.cuttingProgressMax){KitchenObjectSO outputKitchObjectSO = GetOutputForInput(GetKitchenObject().GetKitchenObjectSO());GetKitchenObject().DestroySelf();KitchenObject.SpawnKitchenObject(outputKitchObjectSO, this);}}}// private bool HasRecipeWithInput(KitchenObjectSO inputKitchenObjectSO){CuttingRecipeSO cuttingRecipeSO = GetCuttingRecipeSOWithInput(inputKitchenObjectSO);return cuttingRecipeSO != null;}// private KitchenObjectSO GetOutputForInput(KitchenObjectSO inputKitchenObjectSO){CuttingRecipeSO cuttingRecipeSO = GetCuttingRecipeSOWithInput(inputKitchenObjectSO);if (cuttingRecipeSO != null){return cuttingRecipeSO.output;}else{return null;}}private CuttingRecipeSO GetCuttingRecipeSOWithInput(KitchenObjectSO inputKitchenObjectSO){foreach (CuttingRecipeSO cuttingRecipeSO in cuttingRecipeSOArray){if (cuttingRecipeSO.input == inputKitchenObjectSO){return cuttingRecipeSO;}}return null;}
}

7、编辑ProgressBarUI.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;public class ProgressBarUI : MonoBehaviour
{[SerializeField] private CuttingCounter cuttingCounter;[SerializeField] private Image barImage;private void Start(){cuttingCounter.OnProgressChanged += CuttingCounter_OnProgressChanged;barImage.fillAmount = 0f;Hide();}private void CuttingCounter_OnProgressChanged(object sender, CuttingCounter.OnprogressChangedEventArgs e){barImage.fillAmount = e.progressNormalized;if (e.progressNormalized == 0f || e.progressNormalized == 1f){Hide();}else{Show();}}private void Show(){gameObject.SetActive(true);}private void Hide(){gameObject.SetActive(false);}
}

8、增加委托事件：编辑CuttingCounter.cs

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.EventSystems;public class CuttingCounter : BaseCounter
{public event EventHandler<OnprogressChangedEventArgs> OnProgressChanged;public class OnprogressChangedEventArgs : EventArgs{public float progressNormalized;}// 委托事件public event EventHandler Oncut;[SerializeField] private CuttingRecipeSO[] cuttingRecipeSOArray;private int cuttingProgress;public override void Interact(Player player){if (!HasKitchenObject()){// There is no KitchenObject hereif (player.HasKitchenObject()){// player is carrying somethingif (HasRecipeWithInput(player.GetKitchenObject().GetKitchenObjectSO())){// Player carrying something that can be cutplayer.GetKitchenObject().SetKitchenObjectParent(this);cuttingProgress = 0;// CuttingRecipeSO cuttingRecipeSO = GetCuttingRecipeSOWithInput(GetKitchenObject().GetKitchenObjectSO());OnProgressChanged?.Invoke(this, new OnprogressChangedEventArgs{progressNormalized = (float)cuttingProgress / cuttingRecipeSO.cuttingProgressMax});}}else{// Player not carrying anything}}else{// There is a KitchenObject hereif (player.HasKitchenObject()){// Player is carrying something}else{// Player is not carrying anythingGetKitchenObject().SetKitchenObjectParent(player);}}}public override void InteractAlternate(Player player){if (HasKitchenObject() && HasRecipeWithInput(GetKitchenObject().GetKitchenObjectSO())){// There is a KitchenObject her and it can be cutcuttingProgress++;// 委托事件Oncut?.Invoke(this,EventArgs.Empty);CuttingRecipeSO cuttingRecipeSO = GetCuttingRecipeSOWithInput(GetKitchenObject().GetKitchenObjectSO());// OnProgressChanged?.Invoke(this, new OnprogressChangedEventArgs{progressNormalized = (float)cuttingProgress / cuttingRecipeSO.cuttingProgressMax});if (cuttingProgress >= cuttingRecipeSO.cuttingProgressMax){KitchenObjectSO outputKitchObjectSO = GetOutputForInput(GetKitchenObject().GetKitchenObjectSO());GetKitchenObject().DestroySelf();KitchenObject.SpawnKitchenObject(outputKitchObjectSO, this);}}}// private bool HasRecipeWithInput(KitchenObjectSO inputKitchenObjectSO){CuttingRecipeSO cuttingRecipeSO = GetCuttingRecipeSOWithInput(inputKitchenObjectSO);return cuttingRecipeSO != null;}// private KitchenObjectSO GetOutputForInput(KitchenObjectSO inputKitchenObjectSO){CuttingRecipeSO cuttingRecipeSO = GetCuttingRecipeSOWithInput(inputKitchenObjectSO);if (cuttingRecipeSO != null){return cuttingRecipeSO.output;}else{return null;}}private CuttingRecipeSO GetCuttingRecipeSOWithInput(KitchenObjectSO inputKitchenObjectSO){foreach (CuttingRecipeSO cuttingRecipeSO in cuttingRecipeSOArray){if (cuttingRecipeSO.input == inputKitchenObjectSO){return cuttingRecipeSO;}}return null;}
}

9、设置切片动画

(1) 复制Project/Scripts 文件夹下的 ContainerCounterVisual.cs，重命名为CuttingCounterVisual

(2) 打开CuttingCounterVisual.cs，更改类名为CuttingCounterVisual

(3) 重命名OPEN_CLOSE为CUT，字符串改为“Cut”

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class CuttingCounterVisual : MonoBehaviour
{private const string CUT = "Cut";[SerializeField] private CuttingCounter cuttingCounter;private Animator animator;private void Awake(){animator = GetComponent<Animator>();}private void Start(){cuttingCounter.Oncut += CuttingCounter_Oncut;}private void CuttingCounter_Oncut(object sender, System.EventArgs e){animator.SetTrigger(CUT);}
}

(4) 编辑预制体CuttingCounter，给子物体CuttingCounter_Visual添加CuttingCounterVisual.cs组件

(5) 赋值

(6) 测试可见刀的动作

七、切菜进度条朝向摄像机

1、复制一个处理台

2、编辑CuttingCounter预制体，给子物体ProgressBarUI 添加LookAtCamera.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class LookAtCamera : MonoBehaviour
{private enum Mode{LookAt,LookAtInverted,CameraForward,CameraForwardInverted,}[SerializeField] private Mode mode;private void LateUpdate(){switch (mode){case Mode.LookAt:transform.LookAt(Camera.main.transform);break;case Mode.LookAtInverted:Vector3 dirFromCamera = transform.position - Camera.main.transform.position;transform.LookAt(transform.position + dirFromCamera);break;case Mode.CameraForward:transform.forward = Camera.main.transform.forward;break;case Mode.CameraForwardInverted:transform.forward = -Camera.main.transform.forward;break;}}
}

3、赋值
