项目过后对项目功能进行记录,(width*height)风格背包实现细节，包含对物体的存放,装备,替换,对未知装备的鉴定,物体前缀的获取，项目类型为tcg+rpg,背包的作用主要为游戏中的物品的获取存放,卡牌的获取管理,对可叠加物品的存放,(width*height)的目的为对物品的存放管理,其效果如下
- 基础物品 (width*height)
物品的创建通过ScriptObject进行创建，根据物品类型设计相关的尺寸(width*height),利用deepcopy创建实体存放如背包，项目的物品管理通过一个独立的类
ItemDatabase进行管理,在玩家获取一个新物品(未鉴定),通过一个随机生成类来产生词缀和属性
本项目物品的生成通过deepcopy生成物品并添加进itemdatabse，Itemdatabase的作用对游戏物品资产的管理以及生成,有利于未知装备的生成,在对商品商管理上,添加未知随机的装备可以为游戏的物品提高游戏性
public static ItemClass DeepCopy(ItemClass obj) { GameObject oj = obj.worldObject; //ItemClass is item base class ItemClass i = (ItemClass)Process(obj); i.worldObject = oj; return i; } static object Process(object obj) { if(obj==null) return null; Type type=obj.GetType(); if(type.IsValueType || type==typeof(string)) { return obj; } else if(type.IsArray) { Type elementType=Type.GetType( type.FullName.Replace("[]",string.Empty)); var array=obj as Array; Array copied=Array.CreateInstance(elementType,array.Length); for(int i=0; i<array.Length; i++) { copied.SetValue(Process(array.GetValue(i)),i); } return Convert.ChangeType(copied,obj.GetType()); } else if(type.IsClass) { object toret=Activator.CreateInstance(obj.GetType()); FieldInfo[] fields=type.GetFields(BindingFlags.Public| BindingFlags.NonPublic|BindingFlags.Instance); foreach(FieldInfo field in fields) { object fieldValue=field.GetValue(obj); if(fieldValue==null) continue; field.SetValue(toret, Process(fieldValue)); } return toret; } else throw new ArgumentException("Unknown type"); }
2.生成slot并将物品存放进slot(width*height)
在物品添加进背包时,根据几个条件进行判断
1.slot是否能填充进去
在物品添加进背包栏,需要检测物品尺寸是否越过背包限制并物品之间是否存在重叠,重叠状态一般在物品编辑器中设置(通常为药水...)，当不可叠加物品存在重叠状态中，获取状态颜色并提示状态
//检测边界以及叠加状态 public bool CheckItemFit(ItemClass item, InventorySlot slot, bool skipLastCheck) { //Run through all the slots that the item occupies for(int i = 0; i < item.height; i++) { for(int j = 0; j < item.width; j++) { //Check if the slot exists if(slot.itemStartNumber + inventoryWidth * i + j >= items.Count) { return false; } //Check to see if the first slot is located at the edge of the inventory for(int k = 0; k < item.height; k++) { if(slot.itemStartNumber + inventoryWidth * k + j != slot.itemStartNumber + inventoryWidth * k) { if(((slot.itemStartNumber + inventoryWidth * i + j ) % inventoryWidth == 0) && item.width != 1) { return false; } } } //Last check is only used sometimes //Checks to see if there's already something in the slots if(!skipLastCheck) { if(items[slot.itemStartNumber + inventoryWidth * i + j].itemStartNumber != slot.itemStartNumber + inventoryWidth * i + j) { return false; } } else { List<int> counter = new List<int>(); for(int l = 0; l < item.height; l++) { for(int m = 0; m < item.width; m++) { if((slot.itemStartNumber + inventoryWidth * (item.height - 1) + (item.width - 1)) < items.Count - 1 && items[slot.itemStartNumber + inventoryWidth * l + m].itemStartNumber != slot.itemStartNumber && items[slot.itemStartNumber + inventoryWidth * l + m].item.itemName != "" && !counter.Contains(items[slot.itemStartNumber + inventoryWidth * l + m].itemStartNumber)) { counter.Add(items[slot.itemStartNumber + inventoryWidth * l + m].itemStartNumber); } } } if(counter.Count > 1) { //return false if there's more than one item return false; } else if(counter.Count == 1) { return true; } } } } return true; }
当物品状态为可添加时,添加进slot,根据width*height尺寸进行添加
for(int l = 0; l < item.height; l++) { for(int m = 0; m < item.width; m++) { //First we add the items to the slots the it fills and set their slots to clear items[i + inventoryWidth * l + m].item = DeepCopy(item); items[i + inventoryWidth * l + m].itemStartNumber = i; items[i + inventoryWidth * l + m].GetComponent<Image>().color = Color.clear; items[i + inventoryWidth * l + m].stacksizeText.gameObject.SetActive(false); //If it's the first index of the added item if(items.IndexOf(items[i + inventoryWidth * l + m]) == i) { SetSlotImageSprite(items[i + inventoryWidth * l + m], item.icon); items[i + inventoryWidth * l + m].itemFrame.gameObject.SetActive(true); items[i + inventoryWidth * l + m].itemFrame.GetComponent<CanvasGroup>().interactable = true; items[i + inventoryWidth * l + m].itemFrame.GetComponent<CanvasGroup>().blocksRaycasts = true; items[i + inventoryWidth * l + m].GetComponent<CanvasGroup>().blocksRaycasts = true; items[i + inventoryWidth * l + m].itemFrame.rectTransform.sizeDelta = new Vector2(item.width * slotIconSize, item.height * slotIconSize); //If the item is stackable if(item.stackable) { items[i + inventoryWidth * l + m].stacksizeText.gameObject.SetActive(true); items[i + inventoryWidth * l + m].stacksizeText.text = item.stackSize.ToString(); } //The item is unidentified if(item.unidentified) { items[i + inventoryWidth * l + m].itemImage.color = Color.red; items[i + inventoryWidth * l + m].unidentified.gameObject.SetActive(true); } } } }
2.物品是否存在物品
当物品存在物品时,需要对存在物品的占用尺寸进行判断(int slot=indexof(item)),当slot存在物品时,遍历slot.count 获取空栏位并存放,另外一种情况是当玩家处于dragging状态时,可以对物品进行替换，存放在物品的方式一般为
Items[slot.itemStartNumber + inventoryWidth * l + m].item.variables
