　材料类

1 2 3 4 5 6 7 8 9 10

/// <summary> /// 材料类 /// </summary> public class Material : Item {       public Material(int id, string name, ItemType type, ItemQuality quality, string des, int capacity, int buyPrice, int sellPrice,string sprite)         : base(id, name, type, quality, des, capacity, buyPrice, sellPrice,sprite)     {     } }

二、UI搭建　　

1.创建一个BagPanel，在其下面创建Scroll View，可以滑动的包，

2.在Content下创建空对象BagGridPanel，并添加组件GridLayoutGroup、Canvas Group。GridLayoutGroup组件Cell Size设置80X80,Spacing:10X8。添加脚本knapsack

3.在BagGridPanel下创建BagFrame物品槽，添加脚本Slot。并拖成预制体

4.在BagFrame下创建itemsprite（Imge）和ItemAmount(Text)，添加脚本ItemUI，并拖成预制体

三、编写Json文件

1.https://www.bejson.com/jsoneditoronline/这个网址可以在线编写Json文件

四、解析Json文件

1.Json文件放在Resources文件夹下

2.创建厂库管理对象脚本InventoryManager

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23
