1.案例简介

#include "broadSword.h"

//构造函数
BroadSword::BroadSword()
{
   FileManager fm;
   map<string, map<string, string>> mWeapon;
   fm.loadCSVData("Weapons.csv", mWeapon);

//武器id
string id = mWeapon["2"]["weaponId"];

   //武器名称
   this->weaponName = mWeapon[id]["weaponName"];
   //武器攻击力
   this->baseDamage = atoi(mWeapon[id]["weaponAtk"].c_str());
   //武器暴击系数
   this->critPlus = atoi(mWeapon[id]["weaponCritPlus"].c_str());
   //武器暴击率
   this->critRate = atoi(mWeapon[id]["weaponCritRate"].c_str());
   //武器吸血系数
   this->suckPlus = atoi(mWeapon[id]["weaponSuckPlus"].c_str());
   //武器吸血率
   this->suckRate = atoi(mWeapon[id]["weaponSuckRate"].c_str());
   //武器冰冻率
   this->frozenRate = atoi(mWeapon[id]["weaponFrozenRate"].c_str());
}

//获取基础伤害
int BroadSword::getBaseDamage()
{
return this->baseDamage;
}

//暴击效果返回值大于0 触发暴击否则不触发
int BroadSword::getCrit()
{
   if (isTrigger(this->critRate))
   {
       return this->baseDamage * this->critPlus;
   }
   else
   {
       return 0;
   }
}

//吸血效果返回值大于0 触发吸血否则不触发
int BroadSword::getSuckBlood()
{
   if (isTrigger(this->suckRate))
   {
       return this->baseDamage * this->suckPlus;
   }
   else
   {
       return 0;
   }

}

//冰冻效果返回true代表触发否则不触发
bool BroadSword::getFrozen()
{
   if (isTrigger(this->frozenRate))
   {
       return true;
   }
   else
   {
       return false;
   }

}

//触发概率的算法
bool BroadSword::isTrigger(int rate)
{
   int num = rand() % 100 + 1; // 1 ~ 100
   if (num <= rate)
   {
       return true;
   }
   return false;

}

2.CSV文件制作

3.解析单行CSV数据

#include "fileManager.h"

//加载CSV格式文件
void FileManager::loadCSVData(string path, map<string, map<string, string>>& mData)
{
//读文件
ifstream ifs(path);

   if (!ifs.is_open())
   {
       cout << "文件打开失败" << endl;
       return;
   }

   //第一个数据
   string firstLine;
   ifs >> firstLine;

//cout << "第一行数据为： " << firstLine << endl;
//heroId,heroName,heroHp,heroAtk,heroDef,heroInfo

vector<string>vFirst; //第一行解析后数据放入的容器

this->parseLineToVector(firstLine, vFirst);

   //测试
   /*for (vector<string>::iterator it = vFirst.begin(); it != vFirst.end(); it++)
   {
       cout << *it << endl;
   }*/

   string otherLine;
   while (ifs >> otherLine)
   {
       //cout << "otherLine = " << otherLine << endl;

vector<string>vOther;

this->parseLineToVector(otherLine, vOther);

       map<string, string>m;
       for (int i = 0; i < vFirst.size(); i++)
       {
           m.insert(make_pair(vFirst[i], vOther[i]));
       }
       //将小map容器插入到大map容器中
       mData.insert(make_pair(vOther[0], m));
   }

   //cout << "第一个英雄姓名： " << mData["1"]["heroName"] << endl;
   //cout << "第二个英雄血量： " << mData["2"]["heroHp"] << endl;
   //cout << "第三个英雄攻击力： " << mData["3"]["heroAtk"] << endl;
}

//解析单行数据到vector容器中
void FileManager::parseLineToVector(string line, vector<string>& v)
{
int pos = -1;
int start = 0;

   while (true)
   {
       pos = (int)line.find(",", start);
       if (pos == -1)
       {
           //最后一个单词处理
           string temp = line.substr(start);
           v.push_back(temp);
           break;
       }
       string temp = line.substr(start, pos - start);
       v.push_back(temp);
       start = pos + 1;
   }

}
