角色换装及属性动态改变

同样利用了Attribute设计，其实角色这里已经很简单了

效果图

白属性
这里写图片描述
装备剑，攻击力+10

装备匕首，攻击力+8

装备三级匕首，攻击加24

同样角色属性的改变是通过之前写的PlayerStatus进行赋值

大致示意图

这里写图片描述

思路

通过装备按钮，更改PlayerStatus的装备属性，并重新计算角色总属性，然后触发PlayerStatus的换装事件，通知角色属性面板刷新。

弹出框修改

同样，界面绑定都从ItemStaus取值，在装备按钮事件中首先改变PlayerStatus的对应属性，这里是Weapon

public class UIItemToolTip : UIScene {    private Image m_Icon;    private Text m_NameText;    private Text m_LvText;    private Text m_TypeText;    private Text m_DescriptionText;    private Text m_AttributeText;    private Text m_BtnDressOnText;    private Text m_BtnDropText;    private Text m_RedPriceText;    private Text m_BluePriceText;    private UISceneWidget m_BtnClose;    private UISceneWidget m_BtnDressOn;    private UISceneWidget m_BtnDrop;    private ItemStatus m_ItemStatus;    private PlayerStatus m_PlayerStatus;    void Awake()    {        this.m_Icon = UIHelper.FindChild<Image>(transform, "imgIcon/Image");        this.m_NameText = UIHelper.FindChild<Text>(transform, "txtName");        this.m_LvText = UIHelper.FindChild<Text>(transform, "txtLv");        this.m_TypeText = UIHelper.FindChild<Text>(transform, "txtType");        this.m_DescriptionText = UIHelper.FindChild<Text>(transform, "txtDescription");        this.m_AttributeText = UIHelper.FindChild<Text>(transform, "imgAttribute/txtAttribute");        this.m_BtnDressOnText = UIHelper.FindChild<Text>(transform, "btnDressOn/Text");        this.m_BtnDropText = UIHelper.FindChild<Text>(transform, "btnDrop/Text");        this.m_BluePriceText = UIHelper.FindChild<Text>(transform, "txtBluePrice");        this.m_RedPriceText = UIHelper.FindChild<Text>(transform, "txtRedPrice");        GameObject player = GameObject.FindGameObjectWithTag("Player");        this.m_PlayerStatus = player.GetComponent<PlayerStatus>();    }    protected override void Start()    {        base.Start();        m_BtnClose = this.GetWidget("btnClose");        if(m_BtnClose != null)            m_BtnClose.PointerClick += BtnClosePointerClick;        m_BtnDressOn = this.GetWidget("btnDressOn");        if(m_BtnDressOn != null)            m_BtnDressOn.PointerClick += BtnDressOnPointerClick;        m_BtnDrop = this.GetWidget("btnDrop");        if(m_BtnDrop != null)            m_BtnDrop.PointerClick += BtnDropPointerClick;    }    public void Show(ItemStatus itemStatus, bool isLeft)    {        this.SetVisible(true);        this.m_ItemStatus = itemStatus;        this.m_Icon.overrideSprite = Resources.Load<Sprite>(m_ItemStatus.IconPath);        this.m_NameText.text = m_ItemStatus.ItemName;        this.m_DescriptionText.text = m_ItemStatus.Description;        this.m_LvText.text = string.Format("等级： {0}", m_ItemStatus.Lv);        this.m_TypeText.text = m_ItemStatus.ItemTypeString;        this.m_AttributeText.text = m_ItemStatus.AttributeString;        this.m_BtnDressOnText.text = GetButtonDressonText(m_ItemStatus.ItemType);        this.m_BtnDropText.text = "丢弃";        GetPriceText(m_ItemStatus.Price);        Vector3 pos = transform.localPosition;        if (isLeft)        {            transform.localPosition = new Vector3(-Mathf.Abs(pos.x), pos.y, pos.z);        }        else        {            transform.localPosition = new Vector3(Mathf.Abs(pos.x), pos.y, pos.z);        }    }    private void BtnClosePointerClick(PointerEventData obj)    {        this.SetVisible(false);    }    private void BtnDropPointerClick(PointerEventData obj)    {    }//换装按钮，给PlayerStatus进行对应属性赋值    private void BtnDressOnPointerClick(PointerEventData obj)    {        switch (m_ItemStatus.ItemType)        {            case ItemType.Weapon:                this.m_PlayerStatus.Weapon = this.m_ItemStatus;                break;            case ItemType.Armor:                this.m_PlayerStatus.Armor = this.m_ItemStatus;                break;            case ItemType.Necklace:                this.m_PlayerStatus.Necklace = this.m_ItemStatus;                break;            case ItemType.Ring:                this.m_PlayerStatus.Ring = this.m_ItemStatus;                break;        }        this.SetVisible(false);    }    private string GetButtonDressonText(ItemType itemType)    {        string result = string.Empty;        switch (itemType)        {            case ItemType.Armor:            case ItemType.Weapon:            case ItemType.Ring:            case ItemType.Necklace:                result = "装备";                break;            case ItemType.Potion:                result = "使用";                break;        }        return result;    }    private void GetPriceText(int price)    {        int sellPrice = (int)(price * 0.8); //售价打八折        m_RedPriceText.text = (sellPrice / 100).ToString();        m_BluePriceText.text = (sellPrice % 100).ToString();    }}

PlayerStatus修改

增加装备的AttributeNode，由外部更换，增加换装事件

public class PlayerStatus : MonoBehaviour {    private UserEntity m_User;    private ItemStatus m_Weapon;    private ItemStatus m_Armor;    private ItemStatus m_Necklace;    private ItemStatus m_Ring;    public double m_MultipleExp = 1.18;    public int m_StartExp = 40;    public string PlayerName { get; set; }    public int Lv { get; set; }    public int LvMax { get; set; }    public double Exp { get; set; }    public double ExpMax { get; set;}    public double HpRegenTime { get; set; }    public double MpRegenTime { get; set; }    public ItemStatus Weapon    {        get        {            return this.m_Weapon;        }        set        {            //卸下当前装备            if (this.m_Weapon != null)                statusEquip.RemoveNode(this.m_Weapon.status);            //穿上新装备            this.m_Weapon = value;            //更新装备数据            InitStatusEquip();            //更新角色数据            status.Calculate();            //触发换装事件            if(ChangedEquip != null)            {                ChangedEquip();            }        }    }    public ItemStatus Armor { get; set; }    public ItemStatus Necklace { get; set; }    public ItemStatus Ring { get; set; }    private AttributeNode statusGrowth = new AttributeNode();    private AttributeNode statusEquip = new AttributeNode();    private AttributeNode statusBuff = new AttributeNode();    public AttributeRoot status = new AttributeRoot();    public event Action ChangedEquip;    void Start()    {    }    public void Load(UserEntity user)    {        this.m_User = user;        this.Lv = this.m_User.Lv;        this.PlayerName = this.m_User.Name;        this.Exp = this.m_User.Exp;        this.ExpMax = m_StartExp * m_MultipleExp * this.Lv;        this.LvMax = this.m_User.Hero.MaxLv;        this.HpRegenTime = this.m_User.HpRegenTime;        this.MpRegenTime = this.m_User.MpRegenTime;        InitAllStatus();    }    private void InitAllStatus()    {        InitStatusGrowth();        InitStatusEquip();        InitStatus(true);    }    private void InitStatusGrowth()    {        this.statusGrowth.Hp = this.Lv * this.m_User.Hero.HpGrowth;        this.statusGrowth.Mp = this.Lv * this.m_User.Hero.MpGrowth;        this.statusGrowth.Atk = this.Lv * this.m_User.Hero.AtkGrowth;        this.statusGrowth.Def = this.Lv * this.m_User.Hero.DefGrowth;        this.statusGrowth.Spd = this.Lv * this.m_User.Hero.SpdGrowth;        this.statusGrowth.Hit = this.Lv * this.m_User.Hero.HitGrowth;        this.statusGrowth.CriticalRate = this.Lv * this.m_User.Hero.CriticalRateGrowth;        this.statusGrowth.AtkSpd = this.Lv * this.m_User.Hero.AtkSpdGrowth;        this.statusGrowth.AtkRange = this.Lv * this.m_User.Hero.AtkRangeGrowth;        this.statusGrowth.MoveSpd = this.Lv * this.m_User.Hero.MoveSpdGrowth;    }//装备的AttributeNode    private void InitStatusEquip()    {        if(this.m_Weapon != null)            this.statusEquip.AddNode(this.m_Weapon.status);    }    private void InitStatus(bool isInit)    {        this.status.Hp = this.m_User.Hero.Hp;        this.status.Mp = this.m_User.Hero.Mp;        this.status.Atk = this.m_User.Hero.Atk;        this.status.Def = this.m_User.Hero.Def;        this.status.Spd = this.m_User.Hero.Spd;        this.status.Hit = this.m_User.Hero.Hit;        this.status.CriticalRate = this.m_User.Hero.CriticalRate;        this.status.AtkSpd = this.m_User.Hero.AtkSpd;        this.status.AtkRange = this.m_User.Hero.AtkRange;        this.status.MoveSpd = this.m_User.Hero.MoveSpd;        this.status.AddNode(this.statusGrowth);        this.status.AddNode(this.statusEquip);        this.status.AddNode(this.statusBuff);        this.status.Calculate(isInit);    }}
