本文主要是介绍UNITY-(width*height)style Inventory，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
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 classItemClass 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;}elsethrow 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 occupiesfor(int i = 0; i < item.height; i++) {for(int j = 0; j < item.width; j++) {//Check if the slot existsif(slot.itemStartNumber + inventoryWidth * i + j >= items.Count) {return false;}//Check to see if the first slot is located at the edge of the inventoryfor(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 slotsif(!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 itemreturn 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 clearitems[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 itemif(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 stackableif(item.stackable) {items[i + inventoryWidth * l + m].stacksizeText.gameObject.SetActive(true);items[i + inventoryWidth * l + m].stacksizeText.text = item.stackSize.ToString();}//The item is unidentifiedif(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
