底层框架构建

底层网格系统构建使用泛型类 GridXY<TGridObject>，它提供了背包的核心管理功能。以下是该系统的核心实现：

// 泛型，满足扩展需求;
public class GridXY<TGridObject>
{// 定义基本信息大小private int width;  private int height;  private float cellSize;  private Vector3 originPosition;  private TGridObject[,] gridArray;// 背包内容管理器，提供物品查询支持private Dictionary<string, int> Bag;public GridXY(******){// 初始化背包}// 提供基础操作public int GetWidth() {  return width;  }  public int GetHeight() {  return height;  }//.......// 提供底层核心操作// 设置物品public void SetGridObject(int x, int y, TGridObject value) {  if (x >= 0 && y >= 0 && x < width && y < height) {  gridArray[x, y] = value;}}// 获取物品public TGridObject GetGridObject(int x, int y) {  if (x >= 0 && y >= 0 && x < width && y < height) {  return gridArray[x, y];  } else {  return default(TGridObject);  }}// 取出物品public int OutObjectCount(String name, int number)  {  if (Bag.ContainsKey(name))  {        int tem = Bag[name];  if (tem > number)  {            Bag[name] -= number;  return number;  }        Bag.Remove(name);  return tem;  }    return 0;  }// 放入物品public void InObjectCount(String name, int number)  {  if (Bag.ContainsKey(name))  {        Bag[name] += number;  Debug.LogWarning(name + "还有" + Bag[name]);  return;  }    Bag.Add(name, number);  }}

物品泛型的实现

系统中的物品通过 PlacedObjectTypeSO 实现，允许物品以脚本化对象（ScriptableObject）的形式进行定义，从而方便管理物品的属性和行为。

public class PlacedObjectTypeSO : ScriptableObject
{public string nameString;  // 分别为背包外实例，背包内实例，预览放置实例;// 解决部分模型过于精细或背包过大造成的卡顿;public Transform usePrefab;  public Transform prefab;  public Transform visual;  public int width;  public int height;  public int number;  public int maxNumber;  public int ID;//物品的放置位置相关public List<Vector2Int> GetGridPositionList(Vector2Int offset, Dir dir){};public Vector2Int GetRotationOffset(Dir dir){};
}public class PlacedObject_Done : MonoBehaviour
{// 部分信息private Vector2Int origin;  private PlacedObjectTypeSO.Dir dir;  // 堆叠相关信息private bool canStack; // 疑似冗余信息private int number = 1;  private int maxNumber = 1;// 创建物品public static PlacedObject_Done Create(){Transform placedObjectTransform = Instantiate(*****){};PlacedObject_Done placedObject = placedObjectTransform.GetCom<>();// 从SO文件创建placedObject.Setup(placedObjectTypeSO, origin, dir);return placedObject;}// 信息初始化private void Setup(****)  {  this.placedObjectTypeSO = placedObjectTypeSO;  this.origin = origin;  this.dir = dir;  // 堆叠内容  this.number = placedObjectTypeSO.number;  this.maxNumber = placedObjectTypeSO.maxNumber;  if (maxNumber != number)  {        canStack = true;  }}// 物品的核心信息// 根据选择判断占地信息;public List<Vector2Int> GetGridPositionList() {  return placedObjectTypeSO.GetGridPositionList(origin, dir);  }// 物品的特定操作// 堆叠，且尝试返回剩余值public int Stack(int number)  {  this.number += number;  Debug.Log(this.number);  if (this.number > maxNumber)  {        int temp = this.number - maxNumber;  this.number = maxNumber;  return temp;  }    return 0;  }// 设置数值等public int GetNumber()  {  return number;  }  public void SetNumber(int number)  {  this.number = number;  }
}

核心控制层实现

GridSystemXY 负责控制背包网格的运作。它提供了多个核心操作，例如放置物品、堆叠物品等。

public class GridSystemXY : MonoBehaviour
{// 具体放置的类型，如不习惯，可以解耦独立。public class GridObject{private GridXY<GridObject> grid;  private int x;  private int y;  public PlacedObject_Done placedObject;  // 物品构建时，物品持有当前所在背包的引用;public GridObject(GridXY<GridObject> grid, int x, int y) {  this.grid = grid;  this.x = x;  this.y = y;  placedObject = null;  }// 提供配套的操作public void SetPlacedObject(PlacedObject_Done placedObject) {  this.placedObject = placedObject;  }public bool CanBuild(PlacedObjectTypeSO placedObjectTypeSO){};public bool CanStack(PlacedObjectTypeSO placedObjectTypeSO){};public int Stack(){};}public static GridSystemXY Instance { get; private set; }// 背包管理器，应对多个背包;public Dictionary<int, GridXY<GridSystemXY.GridObject>> gridDictionary;// 当前操作的背包private GridXY<GridObject> grid;// 当前操作的物品private PlacedObjectTypeSO.Dir dir; private PlacedObjectTypeSO placedObjectTypeSO;// 移动位置时的逻辑。  private bool isSwitchingMode = false;  private List<Vector2Int> tempGridPositionList = null;// 备份数据  private int number;// 初始化private void Awake() {  Instance = this;  gridDictionary = new Dictionary<int, GridXY<GridSystemXY.GridObject>>();  int gridWidth = 3;  int gridHeight = 4;  float cellSize = 10f;  AddGrid(1, grid);  AddGrid(2, grid);  placedObjectTypeSO = null;  }// 部分系统// 放置系统private void Build(){foreach(var ID in gridDictionary){//获取鼠标位置，查看是否可以放置}if (canBuild){// 堆叠放置if(canStack){int tem = targetGridObject.Stack(number);if(tem > 0){//未完全放置，仅更新当前数量return;}}// 放置{// 指定位置创建物品placedObject = PlacedObject_Done.Create(****);}// 松开;DeselectObjectType();}}}
