Unity2D初级背包设计中篇 MVC分层撰写(万字详解)-CSDN博客、

如果你已经搞懂了中篇，那么对这个背包的拓展将极为简单，我就在这里举个例子吧

1.添加物品描述信息

2.拓展思路与不足分析

1.没有删除只有丢弃功能，所以可以添加垃圾桶

2.格子有限，可以再做的大一些，也可以添加翻页功能

3.排序与分类功能

4. 逻辑层再封装

5.背包存储可以转为json而不再是让编辑器保存

1.添加物品描述信息

M层修改：

统一到SoltData之中获得

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;[Serializable]
public class SlotData {public ItemData item;public int currentCount = 0; // 物品数量private Action OnChange;#region 增（Add）// 添加物品到槽位public void Add(int numToAdd = 1) {this.currentCount += numToAdd;OnChange?.Invoke();}// 设置槽位的物品和数量public void AddItem(ItemData item, int count = 1) {this.item = item;this.currentCount = count;OnChange?.Invoke();}#endregion#region 删（Remove）// 减少槽位中的物品数量public void Reduce(int numToReduce = 1) {currentCount -= numToReduce;if (currentCount == 0) {Clear();}else {OnChange?.Invoke();}}// 清空槽位public void Clear() {item = null;currentCount = 0;OnChange?.Invoke();}#endregion#region 查（Check）// 检查槽位是否为空public bool IsEmpty() {return currentCount == 0;}// 检查槽位是否可以添加物品public bool CanAddItem() {return currentCount < item.maxCount;}// 获取槽位的空余空间public int GetFreeSpace() {return item.maxCount - currentCount;}#endregion#region 改（Update）// 移动槽位数据public void MoveSlot(SlotData data) {this.item = data.item;this.currentCount = data.currentCount;OnChange?.Invoke();}// 添加监听器public void AddListener(Action OnChange) {this.OnChange = OnChange;}//获取物品描述public string GetDescription() {return item.Description;}#endregion
}

V层修改：

背包UI持有该描述的组件因此将显示和隐藏写到BagUI类

using System.Collections.Generic;
using TMPro;
using Unity.VisualScripting;
using UnityEngine;
using UnityEngine.UI;public class BagUI : MonoBehaviour {[SerializeField] private Button close;[SerializeField] private GameObject BG;[SerializeField] private GameObject slotGrid;[SerializeField] private List<SlotUI> soltuiList = new List<SlotUI>();[SerializeField] private TextMeshProUGUI DText;// Start is called once before the first execution of Update after the MonoBehaviour is createdvoid Start() {InitElement();InitSlotUI();}// Update is called once per framevoid Update() {ColseBag();}public void InitElement() {if(BG==null)BG = transform.Find("BG").gameObject;if (close == null)close = transform.Find("BG/BgElement/Close").GetComponent<Button>();if(slotGrid)slotGrid = transform.Find("BG/SlotGrid").gameObject;if (close != null) {close.onClick.AddListener(() => {if (BG != null)BG.SetActive(!BG.activeSelf);else {Debug.LogWarning("没找到BG对象");return;}});}elseDebug.LogWarning("没有加载到close按钮");}public void UpdataUI() {for (int i = 0; i < InventoryManager.Instance.BagInventory.slotList.Count; i++) {soltuiList[i].SetData(InventoryManager.Instance.BagInventory.slotList[i]);}}public void InitSlotUI() {if (slotGrid != null) {foreach (SlotUI slotUi in slotGrid.GetComponentsInChildren<SlotUI>()) {soltuiList.Add(slotUi);}}UpdataUI();}public void ColseBag() {if (Input.GetKeyDown(KeyCode.Tab))BG.SetActive(!BG.activeSelf);}public void ShowDescription(string description) {DText.gameObject.SetActive(true);DText.text = description;}public void HideDescription() {DText.gameObject.SetActive(false);DText.text = "";}}

之后当鼠标移入SoltUI之后，触发上面两种方法 ,这里可以采用事件发送的方法，也可以直接去持有对象

using System;
using TMPro;
using Unity.VisualScripting;
using UnityEngine;
using UnityEngine.Events;
using UnityEngine.EventSystems;
using UnityEngine.UI;public class SlotUI : MonoBehaviour,IPointerClickHandler,IPointerEnterHandler, IPointerExitHandler {protected SlotData slotData;protected Image icon;protected TextMeshProUGUI num;[SerializeField]private BagUI bagUI;private void Start() {icon = transform.Find("icon").GetComponent<Image>();num = transform.Find("num").GetComponent<TextMeshProUGUI>();}public SlotData GetData(){ return slotData;}/// <summary>/// 为该脚本上的对象赋值一个SlotData/// </summary>public void SetData(SlotData slotData) { this.slotData = slotData;//事件监听 - 订阅者slotData.AddListener(UpdateUI2Slot);UpdateUI2Slot();}/ <summary>/ 监听对象/ </summary>//public void ChangeUI(){//    UpdateUI2Slot();//}private void UpdateUI2Slot(){if (slotData==null || slotData.item == null || slotData.currentCount <= 0) {icon.enabled = false;num.enabled = false;}else {icon.enabled = true;num.enabled = true;icon.sprite = slotData.item.itemSprite;num.text = slotData.currentCount.ToString();}}public void OnPointerClick(PointerEventData eventData) {Debug.Log("发生了点击");ItemMoveHandler.Instance.OnSlotClick(this);}public void OnPointerEnter(PointerEventData eventData) {Debug.Log("鼠标进入");if (slotData.item != null)bagUI.ShowDescription(slotData.GetDescription());}public void OnPointerExit(PointerEventData eventData) {Debug.Log("鼠标离开");if (slotData.item != null)bagUI.HideDescription();}
}
