1、分配被点击物品的索引：编辑InventorySlot.cs，把被点击物品的索引分配给this.slotIndex

//点击的物品槽的索引
int slotIndex;
//把被点击物品的索引分配给this.slotIndex
public void AssignIndex(int slotIndex)
{this.slotIndex = slotIndex;
}

2、为物品栏中的每一个物品分配一个索引值：

(1) 编辑UIManager.cs，创建并在Start方法中调用AssignSlotIndex()方法

void Start()
{RenderInventory();//调用方法AssignSlotIndex();
}
//遍历……数组，并为数组中的每个 InventorySlot 对象分配一个索引值
public void AssignSlotIndex()
{for(int i = 0; i < toolSlots.Length; i++){toolSlots[i].AssignIndex(i);itemSlots[i].AssignIndex(i);}
}

(2) 索引值被传递给InventorySlot.cs中的AssignIndex(int slotIndex)方法，并在slotIndex中显示出来

二、物品槽到装备槽

1、编辑 ItemSlotData.cs

(1) 比较两个物体的itemData属性是否相同（是不是同一种物体——用于堆叠物品）

(2) 判断某itemData是否为空，可结合Empty方法，用于清空物品槽中的物品

using System.Collections;
using System.Collections.Generic;
using UnityEngine;[System.Serializable]
public class ItemSlotData
{public ItemData itemData;public int quantity;public ItemSlotData(ItemData itemData, int quantity){this.itemData = itemData;this.quantity = quantity;ValidateQuantity();}public ItemSlotData(ItemData itemData){this.itemData = itemData;quantity = 1;ValidateQuantity();}public ItemSlotData(ItemSlotData slotToClone){itemData = slotToClone.itemData;quantity = slotToClone.quantity;}public void AddQuantity(){AddQuantity(1);}public void AddQuantity(int amountToAdd){quantity += amountToAdd;}public void Remove(){quantity--;ValidateQuantity();}//比较传入的参数slotToCompare和当前ItemSlotData对象(this)的的itemData属性是否相同//并返回一个布尔值//具体作用：判断二者是否可以叠加//调用方法：A.Stackalbe(B);public bool Stackable(ItemSlotData slotToCompare){return slotToCompare.itemData == itemData;}public void ValidateQuantity(){if (quantity <= 0 || itemData == null){Empty();}}public void Empty(){itemData = null;quantity = 0;}//判断ItemSlotData对象的itemData属性是否为空（null）public bool IsEmpty(){return itemData == null;}
}

2、编辑 InventoryManager.cs

(1) 增加两个物品转移的方法

public void InventoryToHand(int slotIndex,InventorySlot.InventoryType inventoryType)
{Debug.Log("装备物品");
}
public void HandToInventory(InventorySlot.InventoryType inventoryType)
{Debug.Log("收回物品");
}

(2) 检查装备槽位

public void OnValidate()
{//检查装备槽位ValidateInventorySlots(equippedToolSlot);ValidateInventorySlots(equippedItemSlot);//检查物品栏中的物品槽位ValidateInventorySlots(itemSlots);ValidateInventorySlots(toolSlots);
}

(3) 依据选中槽所属的类型，将选中槽赋值给变量handToEquip

    public void InventoryToHand(int slotIndex,InventorySlot.InventoryType inventoryType){ItemSlotData handToEquip;ItemSlotData[] inventoryToAlter;if (inventoryType == InventorySlot.InventoryType.Item){handToEquip = equippedItemSlot;inventoryToAlter = itemSlots;}else{handToEquip = equippedToolSlot;inventoryToAlter = toolSlots;}}

(3) 增加将物品槽中的物品复制到装备槽的方法

public void EquipHandSlot(ItemData item)
{if (IsTool(item)){equippedToolSlot = new ItemSlotData(item);}else{equippedItemSlot = new ItemSlotData(item);}
}
//根据物品类型将选中物品由物品槽复制到装备槽
public void EquipHandSlot(ItemSlotData itemSlot)
{//获取选中物品槽的物品数据ItemData item = itemSlot.itemData;//调用IsTool方法检查物品类型if (IsTool(item)){//(物品是工具类型)将 itemSlot 中的物品数据复制到 equippedToolSlot 中equippedToolSlot = new ItemSlotData(itemSlot);}else{//如果物品不是工具类型，将 itemSlot 中的物品数据复制到 equippedItemSlot 中equippedItemSlot = new ItemSlotData(itemSlot);}
}

(4)  工具槽中的物品转移到装备槽（堆叠或转移）

    public void InventoryToHand(int slotIndex,InventorySlot.InventoryType inventoryType){ItemSlotData handToEquip;ItemSlotData[] inventoryToAlter;if (inventoryType == InventorySlot.InventoryType.Item){handToEquip = equippedItemSlot;inventoryToAlter = itemSlots;}else{handToEquip = equippedToolSlot;inventoryToAlter = toolSlots;}//（选中槽与装备槽物品相同）可以堆叠，同时清空选中槽物品if (handToEquip.Stackable(inventoryToAlter[slotIndex])){ItemSlotData slotToAlter = inventoryToAlter[slotIndex];handToEquip.AddQuantity(slotToAlter.quantity);slotToAlter.Empty();}//不能堆叠，选中槽物品转移到装备槽，同时清空选中槽物品else{//将 inventoryToAlter 数组中的指定索引 slotIndex 的值赋给临时变量 slotToEquipItemSlotData slotToEquip = new ItemSlotData(inventoryToAlter[slotIndex]);//将 handToEquip 的值赋给 inventoryToAlter 数组中的指定索引 slotIndexinventoryToAlter[slotIndex] = new ItemSlotData(handToEquip);//临时变量中的物品复制到装备槽EquipHandSlot(slotToEquip);//清空handToEquip 的值handToEquip.Empty();}UIManager.Instance.RenderInventory();}

 

3、编辑 InventorySlot.cs，实现物品转移

(1) 增加鼠标点击事件，调用InventoryManager.cs方法

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.EventSystems;
using UnityEngine.UI;//增加点击事件接口
public class InventorySlot : MonoBehaviour,IPointerEnterHandler,IPointerExitHandler,IPointerClickHandler
{ItemData itemToDisplay;public Image itemDisplayImage;//点击的物品槽的索引int slotIndex;int quantity;public Text quantityText;public enum InventoryType { Item, Tool }public InventoryType inventoryType;public void Display(ItemSlotData itemSlot){itemToDisplay = itemSlot.itemData;quantity = itemSlot.quantity;quantityText.text = "";if (itemToDisplay != null && itemToDisplay.thumbnail != null){itemDisplayImage.sprite = itemToDisplay.thumbnail;if (quantity > 1){quantityText.text = quantity.ToString();}itemDisplayImage.gameObject.SetActive(true);return;}itemDisplayImage.gameObject.SetActive(false);this.itemToDisplay = null;}public void AssignIndex(int slotIndex){this.slotIndex = slotIndex;}public void OnPointerEnter(PointerEventData eventData){UIManager.Instance.DisplayItemInfo(itemToDisplay);}public void OnPointerExit(PointerEventData eventData){UIManager.Instance.DisplayItemInfo(null);}//点击事件（注意可重写）public virtual void OnPointerClick(PointerEventData eventData){InventoryManager.Instance.InventoryToHand(slotIndex, inventoryType);}
}

(2) 解析：调用InventoryManager.cs方法。传入的参数：点击的物品槽索引，所处的物品栏类型

 4、重写点击事件：

(1) 目的：点击已装备槽时，调用InventoryMagager类中的HandToInventory方法

(2) 编辑HandInventorySlot.cs，传入参数为点击选中槽所属的类型

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.EventSystems;public class HandInventorySlot : InventorySlot
{public override void OnPointerClick(PointerEventData eventData){InventoryManager.Instance.HandToInventory(inventoryType);}
}

三、装备槽到物品槽

1、编辑 InventoryManager.cs

(1) 增加装备槽复制到物品槽的方法

    #region 物品交换的方法//根据物品类型将装备槽中的物品由装备槽复制到物品槽public bool StackItemToInventory(ItemSlotData itemSlot, ItemSlotData[] inventoryArray){//遍历inventoryArray（某类物品栏的物品槽数组）for (int i = 0; i < inventoryArray.Length; i++){//可以堆叠（装备槽物品与物品栏中的某种物品是同种物品）if (inventoryArray[i].Stackable(itemSlot)){inventoryArray[i].AddQuantity(itemSlot.quantity);itemSlot.Empty();return true;}}return false;}public void EquipHandSlot(ItemSlotData itemSlot){ItemData item = itemSlot.itemData;if (IsTool(item)){equippedToolSlot = new ItemSlotData(itemSlot);}else{equippedItemSlot = new ItemSlotData(itemSlot);}}#endregion

(2) 编辑物品由装备槽转移到物品槽的方法

    public void HandToInventory(InventorySlot.InventoryType inventoryType){ItemSlotData handSlot;ItemSlotData[] inventoryToAlter;//确定点击物品的类型并赋值if(inventoryType == InventorySlot.InventoryType.Item){handSlot = equippedItemSlot;inventoryToAlter = itemSlots;}else{handSlot = equippedToolSlot;inventoryToAlter = toolSlots;}if(!StackItemToInventory(handSlot, inventoryToAlter)){for(int i = 0; i < inventoryToAlter.Length; i++){if (inventoryToAlter[i].IsEmpty()){inventoryToAlter[i] = new ItemSlotData(handSlot);handSlot.Empty();break;}}}UIManager.Instance.RenderInventory();}

if (!StackItemToInventory(handSlot, inventoryToAlter)){}

① 先执行StackItemToInventory() 方法，返回一个bool值

② 若物品可以堆叠，则StackItemToInventory() 方法返回的值为true，

if (!StackItemToInventory(handSlot, inventoryToAlter)){}该语句不能执行

③ 若物品不能堆叠，则StackItemToInventory() 方法返回的值为false，

执行 if (!StackItemToInventory(handSlot, inventoryToAlter)){}

2、InventoryManager.cs 的完整代码

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class InventoryManager : MonoBehaviour
{public static InventoryManager Instance { get; private set; }[Header("Tools")][SerializeField] private ItemSlotData[] toolSlots = new ItemSlotData[8];[SerializeField] private ItemSlotData equippedToolSlot = null;[Header("Items")][SerializeField] private ItemSlotData[] itemSlots = new ItemSlotData[8];[SerializeField] private ItemSlotData equippedItemSlot = null;private void Awake(){if (Instance != null && Instance != this) { Destroy(gameObject); }else { Instance = this; }}private void OnDestroy(){if(Instance == this) { Instance = null; }}public void InventoryToHand(int slotIndex,InventorySlot.InventoryType inventoryType){ItemSlotData handToEquip;ItemSlotData[] inventoryToAlter;if (inventoryType == InventorySlot.InventoryType.Item){handToEquip = equippedItemSlot;inventoryToAlter = itemSlots;}else{handToEquip = equippedToolSlot;inventoryToAlter = toolSlots;}if (handToEquip.Stackable(inventoryToAlter[slotIndex])){ItemSlotData slotToAlter = inventoryToAlter[slotIndex];handToEquip.AddQuantity(slotToAlter.quantity);slotToAlter.Empty();}else{ItemSlotData slotToEquip = new ItemSlotData(inventoryToAlter[slotIndex]);inventoryToAlter[slotIndex] = new ItemSlotData(handToEquip);EquipHandSlot(slotToEquip);handToEquip.Empty();}UIManager.Instance.RenderInventory();}public void HandToInventory(InventorySlot.InventoryType inventoryType){ItemSlotData handSlot;ItemSlotData[] inventoryToAlter;if(inventoryType == InventorySlot.InventoryType.Item){handSlot = equippedItemSlot;inventoryToAlter = itemSlots;}else{handSlot = equippedToolSlot;inventoryToAlter = toolSlots;}//将装备槽中的物品堆叠到相应的物品槽中if (!StackItemToInventory(handSlot, inventoryToAlter)){for(int i = 0; i < inventoryToAlter.Length; i++){if (inventoryToAlter[i].IsEmpty()){inventoryToAlter[i] = new ItemSlotData(handSlot);handSlot.Empty();break;}}}UIManager.Instance.RenderInventory();}#region Gets and Checks//手持物品槽的类型public ItemData GetEquippedSlotItem(InventorySlot.InventoryType inventoryType){if (inventoryType == InventorySlot.InventoryType.Item){return equippedItemSlot.itemData;}return equippedToolSlot.itemData;}//选中物品槽的类型public ItemSlotData GetEquippedSlot(InventorySlot.InventoryType inventoryType){if(inventoryType == InventorySlot.InventoryType.Item){return equippedItemSlot;}return equippedToolSlot;}//物品栏中物品槽的类型public ItemSlotData[] GetInventorySlots(InventorySlot.InventoryType inventoryType){if(inventoryType == InventorySlot.InventoryType.Item) {  return itemSlots; }return toolSlots;}//检查特定类型的槽位是否已经装备了物品public bool SlotEquipped(InventorySlot.InventoryType inventoryType){if (inventoryType == InventorySlot.InventoryType.Item){return !equippedItemSlot.IsEmpty();}return !equippedToolSlot.IsEmpty();}//检查给定的物品是否为工具，若为工具或种子，返回为true，否则返回falsepublic bool IsTool(ItemData item){//将 item 强制转换为 EquipmentData 类型，并将结果赋值给 equipment 变量EquipmentData equipment = item as EquipmentData;if (equipment != null){return true;}SeedData seed = item as SeedData;return seed != null;}#endregion#region 物品交换的方法//根据物品类型将装备槽中的物品由装备槽复制到物品槽public bool StackItemToInventory(ItemSlotData itemSlot, ItemSlotData[] inventoryArray){//遍历inventoryArray（某类物品栏的物品槽数组）for (int i = 0; i < inventoryArray.Length; i++){//可以堆叠（装备槽物品与物品栏中的某种物品是同种物品）if (inventoryArray[i].Stackable(itemSlot)){inventoryArray[i].AddQuantity(itemSlot.quantity);itemSlot.Empty();return true;}}return false;}//根据物品类型将选中物品由物品槽复制到装备槽public void EquipHandSlot(ItemSlotData itemSlot){//获取选中物品槽的物品数据ItemData item = itemSlot.itemData;//调用IsTool方法检查物品类型if (IsTool(item)){//(物品是工具类型)将 itemSlot 中的物品数据复制到 equippedToolSlot 中equippedToolSlot = new ItemSlotData(itemSlot);}else{//如果物品不是工具类型，将 itemSlot 中的物品数据复制到 equippedItemSlot 中equippedItemSlot = new ItemSlotData(itemSlot);}}#endregion#region Inventory Slot validation（验证物品栏槽位的有效性）public void OnValidate(){//检查装备槽位ValidateInventorySlots(equippedToolSlot);ValidateInventorySlots(equippedItemSlot);ValidateInventorySlots(itemSlots);ValidateInventorySlots(toolSlots);}void ValidateInventorySlots(ItemSlotData slot){if(slot.itemData != null && slot.quantity == 0){slot.quantity = 1;}}void ValidateInventorySlots(ItemSlotData[] array){foreach(ItemSlotData slot in array){ValidateInventorySlots(slot);}}#endregion
}

状态栏物品和数量

1、编辑UIManager.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;public class UIManager : MonoBehaviour
{public static UIManager Instance { get; private set; }[Header("Inventory System")]public GameObject inventoryPanle;public InventorySlot[] toolSlots;public InventorySlot[] itemSlots;public HandInventorySlot toolHandSlot;public HandInventorySlot itemHandSlot;public Text itemNameText;public Text itemDescriptionText;//状态栏工具数量public Text toolQuantityText;public Image toolEquipSlotImage;private void Awake(){if (Instance != null && Instance != this) { Destroy(gameObject); }else { Instance = this; }}private void OnDestroy(){if (Instance == this) { Instance = null; }}void Start(){RenderInventory();AssignSlotIndex();}public void AssignSlotIndex(){for(int i = 0; i < toolSlots.Length; i++){toolSlots[i].AssignIndex(i);itemSlots[i].AssignIndex(i);}}public void RenderInventory(){ItemSlotData[] inventoryToolSlots = InventoryManager.Instance.GetInventorySlots
(InventorySlot.InventoryType.Tool);RenderInventoryPanel(inventoryToolSlots, toolSlots);ItemSlotData[] inventoryItemSlots = InventoryManager.Instance.GetInventorySlots
(InventorySlot.InventoryType.Item);RenderInventoryPanel(inventoryItemSlots, itemSlots);toolHandSlot.Display(InventoryManager.Instance.GetEquippedSlot
(InventorySlot.InventoryType.Tool));itemHandSlot.Display(InventoryManager.Instance.GetEquippedSlot
(InventorySlot.InventoryType.Item));//手持槽物品ItemData equippedTool = InventoryManager.Instance.GetEquippedSlotItem
(InventorySlot.InventoryType.Tool);//状态栏工具数量的文本toolQuantityText.text = "";if (equippedTool != null){toolEquipSlotImage.sprite = equippedTool.thumbnail;toolEquipSlotImage.gameObject.SetActive(true);//显示状态栏上的工具的数量int quantity = InventoryManager.Instance.GetEquippedSlot
(InventorySlot.InventoryType.Tool).quantity;if (quantity > 1){toolQuantityText.text = quantity.ToString();}return;}toolEquipSlotImage.gameObject.SetActive(false);}void RenderInventoryPanel(ItemSlotData[] slots, InventorySlot[] uiSlots){for (int i = 0; i < uiSlots.Length; i++){uiSlots[i].Display(slots[i]);}}public void DisplayItemInfo(ItemData data){if (data == null){itemNameText.text = "";itemDescriptionText.text = "";return;}itemNameText.text = data.name;itemDescriptionText.text = data.description;}public void ToggleInventoryPanel(){inventoryPanle.SetActive(!inventoryPanle.activeSelf);RenderInventory();}
}

2、赋值

更换土壤状态

详细教程步骤六、2

一、手持农具

1、编辑Player预制体，添加手持物体的位置

     以mixamorig6:RightHand为父物体，Create Empty，重命名为Hand Point

2、添加农具模型

(1) 编辑InventoryManager.cs，创建并调用手持农具的方法

//手持物体的位置
public Transform handPoint;
public void InventoryToHand(int slotIndex,InventorySlot.InventoryType inventoryType)
{//其它代码//手持农具if (inventoryType == InventorySlot.InventoryType.Tool){RenderHand();}UIManager.Instance.RenderInventory();
}
//手持农具的方法
public void RenderHand()
{if (handPoint.childCount > 0){Destroy(handPoint.GetChild(0).gameObject);}if (SlotEquipped(InventorySlot.InventoryType.Tool)){Instantiate(GetEquippedSlotItem(InventorySlot.InventoryType.Tool).gameModel, handPoint);}
}
//检查手持的槽位是否已经装备了物品public bool SlotEquipped(InventorySlot.InventoryType inventoryType){if (inventoryType == InventorySlot.InventoryType.Item){return !equippedItemSlot.IsEmpty();}return !equippedToolSlot.IsEmpty();}

(2) 解析

public bool IsEmpty()
{return itemData == null;
}

equippedToolSlot.IsEmpty() ：判断 equippedToolSlot 是否为空，如果为空，IsEmpty()返回 true

public bool SlotEquipped(InventorySlot.InventoryType inventoryType)
{return !equippedToolSlot.IsEmpty();
}

!equippedToolSlot.IsEmpty() ：取反。

如果equippedToolSlot为空，IsEmpty()返回 true，SlotEquipped()返回false，即：槽位未装备物品

if (SlotEquipped(InventorySlot.InventoryType.Tool))
{Instantiate(GetEquippedSlotItem(InventorySlot.InventoryType.Tool).gameModel,handPoint);
}

if (SlotEquipped(InventorySlot.InventoryType.Tool)) ：如果槽位装备物品，在手持位生成该物品模型

(3) 赋值

3、装备和卸下农具

(1) 编辑InventoryManager.cs

    public void HandToInventory(InventorySlot.InventoryType inventoryType){//其它代码//卸下农具if(inventoryType == InventorySlot.InventoryType.Tool){RenderHand();}UIManager.Instance.RenderInventory();}

二、更改土壤状态

1、编辑Land.cs

    public void Interact(){//根据点击事件决定土壤状态ItemData toolSlot = InventoryManager.Instance.GetEquippedSlotItem(InventorySlot.InventoryType.Tool);if (!InventoryManager.Instance.SlotEquipped(InventorySlot.InventoryType.Tool)){return;}EquipmentData equipmentTool = toolSlot as EquipmentData;if (equipmentTool != null){EquipmentData.ToolType toolType = equipmentTool.Type;switch (toolType){case EquipmentData.ToolType.Hoe: SwitchLandStatus(LandStatus.Farmland); break;case EquipmentData.ToolType.WateringCan: if (landStatus == LandStatus.Farmland||landStatus ==LandStatus.Watered){SwitchLandStatus(LandStatus.Watered);}break;}}}

时间管理系统

详细教程 步骤二

一、设置时间逻辑

1、设定年季周、日时分：Scripts文件夹下创建Time 文件夹，其下创建GameTimestamp.cs，

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
[Serializable]
public class GameTimestamp
{public int year;public enum Season { Spring, Summer, Fall, Winter }public Season season;public enum DayOfTheWeek { Saturday, Sunday, Monday, Tuesday, Wednesday, Thursday, Friday }public int day, hour, minute;public GameTimestamp(int year, Season season, int day, int hour, int minute){this.year = year;this.season = season;this.day = day;this.hour = hour;this.minute = minute;}public void UpdateClock(){minute++;if (minute >= 60) { minute = 0; hour++; }if (hour >= 24) { hour = 0; day++; }if (day > 30){day = 1;if (season == Season.Winter){season = Season.Spring;year++;}else{season++;}}}public GameTimestamp(GameTimestamp timestamp){this.year = timestamp.year;this.season = timestamp.season;this.day = timestamp.day;this.hour = timestamp.hour;this.minute = timestamp.minute;}public static int HoursToMinutes(int hour) { return hour * 60; }public static int DaysToHours(int day) { return day * 24; }public static int SeasonsToDays(Season season){int seasonIndex = (int)season;return seasonIndex * 30;}public static int YearsToDays(int year) { return year * 4 * 30; }public DayOfTheWeek GetDayOfTheWeek(){int daysPassed = YearsToDays(year) + SeasonsToDays(season) + day;int dayIndex = daysPassed % 7;return (DayOfTheWeek)dayIndex;}
}

AI的建议

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;[Serializable]
public class GameTimestamp
{// 时间的定义public enum Season { Spring, Summer, Autumn, Winter }public int hour;public Season season;public int day;public int month;public int year;public int minute;public GameTimestamp(int hour, Season season, int day, int month, int year){this.hour = hour;this.season = season;this.day = day;this.month = month;this.year = year;}public void UpdateClock(){minute++;if (minute >= 60){minute = 0;hour++;if (hour >= 24){hour = 0;day++;if (day > GetDaysInMonth(month)){day = 1;month++;if (month > 12){ month = 1;year++; }}}}}private int GetDaysInMonth(int month){switch (month){case 2:return 28;case 4:case 6:case 9:case 11:return 30;default:return 31;}}public static int HoursToMinutes(int hours){return hours * 60;}
}public class TimeManager : MonoBehaviour
{public static TimeManager Instance { get; private set; }[SerializeField]private GameTimestamp timestamp;public float timeScale = 1.0f;//太阳的位置[Header("Day and Night cycle")]public Transform sunTransform;private void Awake(){if (Instance != null && Instance != this){ Destroy(gameObject); }else { Instance = this; }}private void OnDestroy(){if (Instance == this) { Instance = null; }}void Start(){timestamp = new GameTimestamp(0, GameTimestamp.Season.Spring, 1, 6, 0);StartCoroutine(TimeUpdate());}IEnumerator TimeUpdate(){while (true){Tick();yield return new WaitForSeconds(1f / timeScale);}}public void Tick(){timestamp.UpdateClock();//游戏运行的时间转换成分钟数int timeInminutes = GameTimestamp.HoursToMinutes(timestamp.hour) + timestamp.minute;//太阳与地平线间的夹角float sunAngle = 360f / (24f * 60f) * timeInminutes - 90;//设置太阳的欧拉角（在三维空间中旋转的向量）sunTransform.eulerAngles = new Vector3(sunAngle, 0, 0);}
}

2、时间流逝

(1) 给Manager添加TimeManager.cs组件

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class TimeManager : MonoBehaviour
{public static TimeManager Instance { get; private set; }[SerializeField]public GameTimestamp timestamp;public float timeScale = 1.0f;private void Awake(){if (Instance != null && Instance != this) { Destroy(gameObject); }else { Instance = this; }}private void OnDestroy(){if (Instance == this) { Instance = null; }}void Start(){timestamp = new GameTimestamp(0, GameTimestamp.Season.Spring, 1, 6, 0);StartCoroutine(TimeUpdate());}IEnumerator TimeUpdate(){while (true){Tick();yield return new WaitForSeconds(1 / timeScale);}}public void Tick(){timestamp.UpdateClock();}
}

(2) 流逝逻辑：每隔1秒钟，minute ++;

二、时间与光照

1、编辑TimeManager.cs，设置太阳旋转

//太阳的位置
[Header("Day and Night cycle")]
public Transform sunTransform;void UpdateSunMovement()
{//游戏运行的时间转换成分钟数int timeInminutes = GameTimestamp.HoursToMinutes(timestamp.hour) + timestamp.minute;//太阳与地平线间的夹角float sunAngle = 360f / (24f * 60f) * timeInminutes - 90;//设置太阳的欧拉角（在三维空间中旋转的向量）sunTransform.eulerAngles = new Vector3(sunAngle, 0, 0);
}
public void Tick()
{timestamp.UpdateClock();UpdateSunMovement();
}

2、赋值

3、测试

(1) 编辑PlayerController.cs

public void Update()
{Interact();//时间加速if(Input.GetKey(KeyCode.RightBracket)){TimeManager.Instance.Tick();}
}

(2) 测试：按下右方括号，时间加速

三、时间管理

1、时间接口：新建ITimeTracker.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public interface ITimeTracker
{void ClockUpdate(GameTimestamp timestamp);
}

2、实时更新时间，并将时间信息传递给已注册的时间跟踪器：编辑TimeManager.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class TimeManager : MonoBehaviour
{public static TimeManager Instance { get; private set; }//内部时钟[Header("Internal Clock")][SerializeField]GameTimestamp timestamp;public float timeScale = 1.0f;[Header("Day and Night cycle")]public Transform sunTransform;//存储所有已注册的时间跟踪器List<ITimeTracker> listeners = new List<ITimeTracker>();public void Tick(){timestamp.UpdateClock();//遍历所有已注册的时间跟踪器foreach(ITimeTracker listener in listeners){listener.ClockUpdate(timestamp);}UpdateSunMovement();}//注册时间跟踪器，并添加到listerns列表中public void RegisterTracker(ITimeTracker listener){listeners.Add(listener);}//注销时间跟踪器，并从列表移除public void UnregisterTracker(ITimeTracker listener){listeners.Remove(listener);}
}

四、显示时间

1、编辑UIManager.cs，更新状态栏上的时间

//接口
public class UIManager : MonoBehaviour, ITimeTracker
//状态栏
[Header("Status Bar")]
public Image toolEquipSlotImage;
public Text toolQuantityText;
//时间文本
public Text timeText;
public Text dateText;
void Start()
{RenderInventory();AssignSlotIndex();//注册时间跟踪器TimeManager.Instance.RegisterTracker(this);
}
//处理UI时间回调
public void ClockUpdate(GameTimestamp timestamp)
{int hours = timestamp.hour;int minutes = timestamp.minute;string prefix = "AM";if (hours > 12) { prefix = "PM"; hours -= 12; }//timeText.text = $"{prefix} {hours:00} :{minutes:00}";timeText.text = prefix + hours + ":" + minutes.ToString("00");int day = timestamp.day;string season = timestamp.season.ToString();string dayOfTheWeek = timestamp.GetDayOfTheWeek().ToString();//dateText.text = $"{season} {day} ({dayOfTheWeek})";dateText.text = season + " " + day + " (" + dayOfTheWeek + ")";
}

2、赋值

五、土壤状态随时间改变

1、比较两个时间戳：编辑GameTimestamp.cs

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;[Serializable]
public class GameTimestamp
{public int year;public enum Season { Spring, Summer, Fall, Winter }public Season season;public enum DayOfTheWeek { Saturday, Sunday, Monday, Tuesday, Wednesday, Thursday, Friday }public int day, hour, minute;public GameTimestamp(int year, Season season, int day, int hour, int minute){this.year = year;this.season = season;this.day = day;this.hour = hour;this.minute = minute;}public void UpdateClock(){minute++;if (minute >= 60) { minute = 0; hour++; }if (hour >= 24) { hour = 0; day++; }if (day > 30){day = 1;if (season == Season.Winter){season = Season.Spring;year++;}else{ season++; }}}public GameTimestamp(GameTimestamp timestamp){this.year = timestamp.year;this.season = timestamp.season;this.day = timestamp.day;this.hour = timestamp.hour;this.minute = timestamp.minute;}public static int HoursToMinutes(int hour) { return hour * 60; }public static int DaysToHours(int day) { return day * 24; }public static int SeasonsToDays(Season season){int seasonIndex = (int)season;return seasonIndex * 30;}public static int YearsToDays(int year) { return year * 4 * 30; }public DayOfTheWeek GetDayOfTheWeek(){int daysPassed = YearsToDays(year) + SeasonsToDays(season) + day;int dayIndex = daysPassed % 7;return (DayOfTheWeek)dayIndex;}//比较两个时间戳public static int CompareTimestamp(GameTimestamp timestamp1, GameTimestamp timestamp2){int timestamp1Hours = DaysToHours(YearsToDays(timestamp1.year))+ DaysToHours(SeasonsToDays(timestamp1.season))+ DaysToHours(timestamp1.day) + timestamp1.hour;int timestamp2Hours = DaysToHours(YearsToDays(timestamp2.year))+ DaysToHours(SeasonsToDays(timestamp2.season))+ DaysToHours(timestamp2.day)+ timestamp2.hour;int differnce = timestamp2Hours - timestamp1Hours;//返回 difference 的绝对值return Mathf.Abs(differnce);}
}

2、获取时间戳（timestamp）：编辑TimeManager.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class TimeManager : MonoBehaviour
{public static TimeManager Instance { get; private set; }[SerializeField][Header("Internal Clock")]GameTimestamp timestamp;public float timeScale = 1.0f;[Header("Day and Night cycle")]public Transform sunTransform;List<ITimeTracker> listeners = new List<ITimeTracker>();private void Awake(){if (Instance != null && Instance != this) { Destroy(gameObject); }else { Instance = this; }}private void OnDestroy(){if (Instance == this) { Instance = null; }}void Start(){timestamp = new GameTimestamp(0, GameTimestamp.Season.Spring, 1, 6, 0);StartCoroutine(TimeUpdate());}IEnumerator TimeUpdate(){while (true){Tick();yield return new WaitForSeconds(1 / timeScale);}}void UpdateSunMovement(){int timeInminutes = GameTimestamp.HoursToMinutes(timestamp.hour) + timestamp.minute;float sunAngle = 360f / (24f * 60f) * timeInminutes - 90;sunTransform.eulerAngles = new Vector3(sunAngle, 0, 0);}public void Tick(){timestamp.UpdateClock();foreach(ITimeTracker listener in listeners){listener.ClockUpdate(timestamp);}UpdateSunMovement();}public void RegisterTracker(ITimeTracker listener){listeners.Add(listener);}public void UnregisterTracker(ITimeTracker listener){listeners.Remove(listener);}//获取新的时间戳public GameTimestamp GetGameTimestamp(){return new GameTimestamp(timestamp);}
}

3、土壤状态的改变

(1) 编辑Land.cs，

//接口
public class Land : MonoBehaviour,ITimeTracker
{//灌溉时间GameTimestamp timeWatered;void Start(){renderer = GetComponent<Renderer>();SwitchLandStatus(LandStatus.Soil);Select(false);//注册时间戳TimeManager.Instance.RegisterTracker(this);}public void SwitchLandStatus(LandStatus statusToSwitch){landStatus = statusToSwitch;Material materialToSwitch = soilMat;switch (statusToSwitch){case LandStatus.Soil: materialToSwitch = soilMat; break;case LandStatus.Farmland: materialToSwitch = farmlandMat; break;case LandStatus.Watered: materialToSwitch = wateredMat; //灌溉的时间戳timeWatered = TimeManager.Instance.GetGameTimestamp();break;}renderer.material = materialToSwitch;}//灌溉后土壤状态的变化public void ClockUpdate(GameTimestamp timestamp){if(landStatus == LandStatus.Watered){int hoursElapsed = GameTimestamp.CompareTimestamp(timeWatered, timestamp);if(hoursElapsed > 24){SwitchLandStatus(LandStatus.Farmland);}}}
}

 2、收获作物：编辑InventoryManager.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class InventoryManager : MonoBehaviour
{    public void InventoryToHand(int slotIndex,InventorySlot.InventoryType inventoryType){//其他代码##//手持收获物if(inventoryType == InventorySlot.InventoryType.Item){RenderHand();}UIManager.Instance.RenderInventory();}public void HandToInventory(InventorySlot.InventoryType inventoryType){//其他代码##//手持收获物if(inventoryType == InventorySlot.InventoryType.Item){RenderHand();}UIManager.Instance.RenderInventory();}public void RenderHand(){//其他代码//收获物if (SlotEquipped(InventorySlot.InventoryType.Item)){Instantiate(GetEquippedSlotItem(InventorySlot.InventoryType.Item).gameModel, handPoint);}}
}

3、拾起作物
