Unity3D自学笔记——角色属性设计分析

角色属性设计分析

目前数据库有两张表与角色属性有关heroinfo 和 userinfo



heroinfo

存放英雄的初始属性，和growth(升级后增加值)，如英雄2级了总血量就是

hp + 2 * hp_growth



userinfo

存放英雄的当前属性，即所有属性影响的最终结果



影响角色属性的外因



可以看出主脚的属性其实就是各种状态的计算结果，从图可以看出其实就是一个树状结构，主角就是树的根，于是我用组合模式简单实验了一下。

类图



Attribute 为虚类，主要方法就是Caculate，通过递归计算总属性（这里是hpTotal和mpTotal）

public abstract class Attribute
{
public int Hp { get; set; }
public int Mp { get; set; }
public int HpTotal { get; set; }
public int MpTotal { get; set; }

private Attribute m_Parent;
private string m_Name;
public Attribute(int hp, int mp)
{
this.Hp = hp;
this.Mp = mp;

}

public Attribute(int hp, int mp, string name) : this(hp, mp)
{
this.m_Name = name;
}

public abstract void Calc();
public abstract int ChildCount();
protected void SetParent(Attribute child)
{
child.m_Parent = this;
}

public Attribute GetParent()
{
return this.m_Parent;
}

public void Show()
{
Calc();
Console.WriteLine(string.Format("{0} 属性为： HP {1} MP {2}",this.m_Name, this.HpTotal, this.MpTotal));
}
}

AttributeComponet为节点，实现了Attribute的方法，并且可以添加节点和删除节点

public class AttributeComponent:Attribute
{
private List<Attribute> m_AttributeList = new List<Attribute>
c777
();

public AttributeComponent(int hp, int mp) : base(hp, mp)
{
}

public AttributeComponent(int hp, int mp, string name) : base(hp, mp, name) { }

public override void Calc()
{
this.HpTotal = this.Hp;
this.MpTotal = this.Mp;

foreach (Attribute item in m_AttributeList)
{
//递归计算属性和
if (item.ChildCount() > 0)
item.Calc();

this.HpTotal += item.HpTotal;
this.MpTotal += item.MpTotal;
}
}

public override int ChildCount()
{
return m_AttributeList.Count;
}

public void AddAttribute(Attribute attribute)
{
SetParent(attribute);
this.m_AttributeList.Add(attribute);
}

public void RemoveAttribute(Attribute attribute)
{
m_AttributeList.Remove(attribute);
}
}

测试代码

[TestMethod]
public void TestMethod1()
{
AttributeComponent basic = new AttributeComponent(50, 100, "Ali");
AttributeComponent lvUp = new AttributeComponent(50, 100, "升级增加");
AttributeComponent weapon = new AttributeComponent(10, 20, "无级弓");
AttributeComponent weaponEnchanting = new AttributeComponent(5, 5, "附魔增加");

basic.Show();
Console.WriteLine("升级啦");
Console.WriteLine("---------------------------------------------------");
lvUp.Show();
basic.AddAttribute(lvUp);
basic.Show();
Console.WriteLine();
Console.WriteLine("装备了武器");
Console.WriteLine("---------------------------------------------------");
weapon.Show();
basic.AddAttribute(weapon);
basic.Show();
Console.WriteLine();
Console.WriteLine("武器附魔");
Console.WriteLine("---------------------------------------------------");
weaponEnchanting.Show();
weapon.AddAttribute(weaponEnchanting);
weapon.Show();
basic.Show();
Console.WriteLine();
Console.WriteLine("卸载装备");
Console.WriteLine("---------------------------------------------------");
basic.RemoveAttribute(weapon);
basic.Show();
}

测试结果
