Unity3D 背包系统

作业：

UI 效果制作（你仅需要实现以下效果之一）

进入 NGUI 官方网站，使用 UGUI 实现以下效果

实现效果

参考博客：

背包系统制作： https://blog.kinpzz.com/2016/05/21/unity3d-ugui-Inventory/

人物模型改变：https://blog.uwa4d.com/archives/avartar.html

这次作业，我融合和两篇博客的精髓，实现了官方样例的功能。

通过拖曳装备，可以改变人物身上的模型。完成度十分高。

背包系统的制作过程，师兄的博客里已经十分详细，不再赘述。

接下来介绍一下人物模型的改变。

在人物模型的改变中，将人物模型生成的类Director.cs设置为单例模式。

在Director.cs中：改变武器，只需要按照下面的例子，引用函数即可（身体的其他部位雷同）

public void ChangeWeapon(int num)
    {
        if (!weapon_list[num])
        {
            for (int j = 0; j < weapon_list.Length; j++)
            {
                weapon_list[j] = false;
            }
            weapon_list[num] = true;
 
            character.ChangeWeapon("ch_we_one_hou_" + index[num]);
        }
    }

在DragItem.cs中，拖动位置的识别，是通过对应位置的名称改变的。所以Wear，和collection中Image名称一定要对应！不可以改变。Bag中的名称无所谓。

在DragItem.cs中，例如Weapon1只能拖动到Weapon位置，或者Weapon0和Weapon1位置。

if (curEnter == null)
        {
            myTransform.position = originalPosition;
        }
        else if (curEnter.GetComponent<DragItem>().inWear || inWear)
        {
            string Pre_thisName = this.name.Substring(0, this.name.Length - 1);
            string Pre_curEnterName = curEnter.name.Substring(0, this.name.Length - 1);
            //移动至物品格子上
            if (curEnter.name == Pre_thisName)
            {
                UnityEngine.Debug.Log("移动至物品格子上");
                UnityEngine.Debug.Log(this.name);
                UnityEngine.Debug.Log(this.transform.position);
                UnityEngine.Debug.Log(curEnter.name);
                UnityEngine.Debug.Log(curEnter.transform.position);
                if (this.transform.position.x < 0)
                {
                    string name = this.name;
                    string num_s = name.Substring(name.Length - 1, 1);
                    int num = Convert.ToInt32(num_s);
                    changeBody(num, Pre_thisName, Pre_curEnterName);
                } 
                 
                myTransform.position = curEnter.transform.position;
                originalPosition = myTransform.position;
                curEnter.GetComponent<Image>().color = lastEnterNormalColor;//当前格子恢复正常颜色
 
                curEnter.GetComponent<DragItem>().inWear = !curEnter.GetComponent<DragItem>().inWear;
                inWear = !inWear;
            }
            else if (Pre_curEnterName == Pre_thisName)
            {
                //移动至包裹中的其它物品上
                UnityEngine.Debug.Log("移动至包裹中的其它物品上");
                /*curEnter.name == eventData.pointerDrag.name &&*/
                if (curEnter != eventData.pointerDrag)
                {
                    UnityEngine.Debug.Log("交换：this.name:" + this.name);
                    UnityEngine.Debug.Log(this.transform.position);
                    UnityEngine.Debug.Log("交换：curEnter:" + curEnter.name);
                    UnityEngine.Debug.Log(curEnter.transform.position);
                    if (this.transform.position.x < 0)
                    {
                        string name = this.name;
                        string num_s = name.Substring(name.Length - 1, 1);
                        int num = Convert.ToInt32(num_s);
                        changeBody(num, Pre_thisName, Pre_curEnterName);
                    }
                    else if (this.transform.position.x > 0)
                    {
                        string name = curEnter.name;
                        string num_s = name.Substring(name.Length - 1, 1);
                        int num = Convert.ToInt32(num_s);
                        changeBody(num, Pre_thisName, Pre_curEnterName);
                    }
                     
                    Vector3 targetPostion = curEnter.transform.position;
                    curEnter.transform.position = originalPosition;
                    myTransform.position = targetPostion;
                    originalPosition = myTransform.position;
 
                    curEnter.GetComponent<DragItem>().inWear = !curEnter.GetComponent<DragItem>().inWear;
                    inWear = !inWear;
                }
                else//拖拽至其它对象上面（包裹上的其它区域）
                {
                    myTransform.position = originalPosition;
                }
            } else
            {
                myTransform.position = originalPosition;
            }
        } else
        {
            myTransform.position = originalPosition;
        }
