黑暗之光 Day2

1. 鼠标点击UI检测

UICamera.isOverUI

2. 鼠标指针管理

 public class CussorManager : MonoBehaviour {
     public static CussorManager instance;       // 单例

     public Texture2D cursorAttack;              // 存储鼠标贴图
     public Texture2D cursorLockTarget;
     public Texture2D cursorNormal;
     public Texture2D cursorNpcTalk;
     public Texture2D cursorPick;

     void Start()
     {
         instance = this;
     }

     public void SetNormal()                     // 设置鼠标为正常
     {
         Cursor.SetCursor(cursorNormal, Vector2.zero, CursorMode.Auto);
     }

     public void SetNpcTalk()                    // 设置鼠标为 Npc_talk
     {
         Cursor.SetCursor(cursorNpcTalk, Vector2.zero, CursorMode.Auto);
     }
 }

3. 读取物品文件

 public TextAsset objectsInfoText;
 private Dictionary<int, ObjectInfo> objectsInfoDict = new Dictionary<int, ObjectInfo>();

 // 从文件中读取物品信息
 void ReadInfo()
 {
     string text = objectsInfoText.text;                    // 获取文本内容
     string[] objectsArr = text.Split('\n');                // 以换行符分割字符
     for (int i = ; i < objectsArr.Length; ++i)            // 遍历每一行
     {
         string[] proArr = objectsArr[i].Split(',');         // 以逗号分割属性
         ObjectInfo info = new ObjectInfo();                 // 物品属性
         info.id = int.Parse(proArr[]);
         info.name = proArr[];
         info.iconName = proArr[];
         string type = proArr[];
         info.type = ObjectType.Material;
         switch (type)
         {
             case "Drug":
                 info.type = ObjectType.Drug;
                 break;
             case "Equip":
                 info.type = ObjectType.Equipment;
                 break;
             case "Mat":
                 info.type = ObjectType.Material;
                 break;
         }
         if (info.type == ObjectType.Drug)                   // 物品是药品
         {
             info.hp = int.Parse(proArr[]);
             info.mp = int.Parse(proArr[]);
             info.sellPrice = int.Parse(proArr[]);
             info.buyPrice = int.Parse(proArr[]);
         }
         objectsInfoDict.Add(info.id, info);                  // 加入字典
     }
 }

 // 根据 ID 查找物品信息
 public ObjectInfo GetObjectInfoById(int id)
 {
     ObjectInfo info;
     objectsInfoDict.TryGetValue(id, out info);
     return info;
 }

4. 物品拖拽

　　继承 UIDragDropItem 类。

5. 模拟拾取物品放入背包

 // 根据 id 拾取物品
 public void GetId(int id)
 {
     InventoryItemGrid grid = null;
     // 查找是否已有该物品
     foreach (InventoryItemGrid temp in itemGridList)
     {
         if (temp.GetId() == id)         // 已有
         {
             grid = temp;
             break;
         }
     }
     if (grid != null)
     {
         grid.PlusNum();                 // 该物品数目+1
     }
     else
     {
         // 查找是否有空格子
         foreach (InventoryItemGrid temp in itemGridList)
         {
             if (temp.GetId() == )      // 有空格子
             {
                 grid = temp; break;
             }
         }
         if (grid != null)               // 往空格子里放物品
         {
             GameObject itemGo = NGUITools.AddChild(grid.gameObject, inventoryItemPrefab);
             itemGo.transform.localPosition = Vector3.zero;
             itemGo.GetComponent<UISprite>().depth = ;
             grid.SetId(id);             // 改变各自装的物品
         }
     }
 }

// 根据 id 更换格子物品
public void SetId(int id, int num = )
{
    info = ObjectsInfo.instance.GetObjectInfoById(id);      // 根据 id 查找物品
    this.id = id;
    this.num = num;
    InventoryItem item = GetComponentInChildren<InventoryItem>();
    item.SetIconName(info.iconName);
    numLabel.enabled = true;
    numLabel.text = num.ToString();
}

6. 物体拖拽实现

 protected override void OnDragDropRelease(GameObject surface)
     {
         print(this.tag);
         base.OnDragDropRelease(surface);
         if (surface != null)
         {
             if (surface.tag == Tags.inventoryItemGrid)
             {
                 if (surface != this.transform.parent.gameObject)    // 拖拽到空格子
                 {
                     InventoryItemGrid oldGrid = this.transform.parent.GetComponent<InventoryItemGrid>();
                     InventoryItemGrid newGrid = surface.GetComponent<InventoryItemGrid>();
                     newGrid.SetId(oldGrid.GetId(), oldGrid.GetNum());
                     oldGrid.ClearInfo();
                 }
             }
             else if (surface.tag == Tags.inventoryItem)             // 拖拽到有物体的格子
             {
                 InventoryItemGrid grid1 = this.transform.parent.GetComponent<InventoryItemGrid>();
                 InventoryItemGrid grid2 = surface.transform.parent.GetComponent<InventoryItemGrid>();
                 int id = grid1.GetId();
                 int num = grid1.GetNum();
                 grid1.SetId(grid2.GetId(), grid2.GetNum());
                 grid2.SetId(id, num);
             }
         }

         ResetPos();
     }

     void ResetPos()
     {
         this.transform.localPosition = Vector3.zero;
     }
