拼字游戏玩家的手 [英] Scrabble game player's hand

问题描述

我目前正在制作一个拼字游戏，并且无法从包中抓取瓷砖以制作玩家的手。



这是拼字游戏的代码我有的课程：

I'm currently making a scrabble game and am having trouble with grabbing tiles from the bag to make the player's hand.

Here is the code for the scrabble class that i have:

#ifndef _SCRABBLE_H
#define _SCRABBLE_H

#include <string>
#include <stdlib.h>
#include <time.h>
#include "bagoftiles.h"
#include "topten.h"
#include "hand.h"
#include "randgen.h"

class scrabble
{
public:
	void grabtiles(hand h, bagoftiles b);
};

void scrabble::grabtiles(hand h, bagoftiles b)
{
	RandGen r;
	for (int i = 0;i < 7;i++) {
		h.sett(i, b.gett(r.RandInt(100)));
	}
}

但是当我尝试运行它时，瓷砖最终显示为空白字母为空，价值为0.



并在此澄清我的课程：



实际平铺：

But when i try to run it, the tiles end up showing as blanks with the letter as nothing and the value as 0.

and to clarify here are my classes:

Actual Tile:

#ifndef _TILE_H
#define _TILE_H

#include <string>
#include <sstream>
#include <fstream>
using namespace std;

class tile 
{
public:
	tile();
	tile(string l, int v);

	string getl();
	int getv();
	void setl(string &l);
	void setv(int &v);
private:
	string myl;
	int myv;
};

tile::tile()
{
	myl = "";
	myv = 0;
}

tile::tile(string l, int v)
{
	myl = l;
	myv = v;
}

string tile::getl()
{
	return myl;
}

int tile::getv()
{
	return myv;
}

void tile::setl(string &l)
{
	myl = l;
}

void tile::setv(int &v)
{
	myv = v;
}
#endif

玩家手牌：

Class for Player's Hand:

#ifndef _HAND_H
#define _HAND_H

#include <stdlib.h>
#include <time.h>
#include <string>
#include "tile.h"
using namespace std;

class hand
{
public:
	hand();
	hand(tile t);
	tile gett(int t);
	void sett(int n, tile t);
private:
	tile myt[7];
};

hand::hand()
{
	for (int i = 0;i < 7;i++) {
		myt[i].getl() = "";
	}
}

hand::hand(tile t)
{
	for (int i = 0;i < 7;i++) {
		myt[i] = t;
	}
}

tile hand::gett(int t)
{
	return myt[t];
}

void hand::sett(int n, tile t)
{
	myt[n] = t;
}
#endif

Bag of Tiles类：

Bag Of Tiles Class:

#ifndef _BAGOFTILES_H
#define _BAGOFTILES_H

#include <stdlib.h>
#include <time.h>
#include <string>
#include "tile.h"
using namespace std;

class bagoftiles
{
public:
	bagoftiles();
	bagoftiles(tile t[]);
	tile gett(int t);
	void gettiles();
	void shuffle();
private:
	tile myt[100];
};

bagoftiles::bagoftiles()
{
	for (int i = 0;i < 100;i++){
		myt[i].getl() = "";
	}
}

bagoftiles::bagoftiles(tile t[])
{
	for (int i = 0;i < 100;i++) {
		myt[i] = t[i];
	}
}

tile bagoftiles::gett(int t)
{
	return myt[t];
}

void bagoftiles::gettiles()
{
	string line, sscore;
	int i = 0, freq;
	ifstream myfile("tiles.txt");
	if (myfile.is_open())
	{
		int n = 0;
		while (getline(myfile, line))
		{
			istringstream buffer(line.substr(3, 2));
			buffer >> freq;
			while (i < freq) {
				myt[n].setl(line.substr(0, 1));
				int value;
				istringstream buffer(line.substr(1, 2));
				buffer >> value;
				myt[n].setv(value);
				n++;
				i++;
			}
			i = 0;
		}
		myfile.close();
	}
}

void bagoftiles::shuffle()
{
	srand((unsigned)time(NULL));
	int r;
	tile temp;
	for (int i = 0;i < 100;i++) {
		r = (rand() % 100);
		temp = myt[r];
		myt[r] = myt[i];
		myt[i] = temp;
	}
}
#endif

Main（实际测试人员）：

Main (actual tester):

#include "scrabble.h"
#include <iostream>
#include <string>
using namespace std;

int main()
{
	hand ht;
	bagoftiles bt;
	bt.gettiles();
	bt.shuffle();
	scrabble sc;
	sc.grabtiles(ht, bt);
	//for (int i = 0;i < 100;i++) {
	//	cout << bt.gett(i).getl() << '\t' << bt.gett(i).getv() << endl;
	//}
	for (int i = 0;i < 7;i++) {
		cout << ht.gett(i).getl() << '\t' << ht.gett(i).getv() << endl;
	}
	system("pause");
	return 0;
}

推荐答案

你的代码没有你想象的那样，你不明白为什么！



有一个几乎通用的解决方案：逐步在调试器上运行代码。

掌握Visual Studio 2010中的调试 - 初学者指南 [ ^ ]



这个解决方案的缺点：

- 这是一个DIY，你是跟踪问题并找到根源的人，这导致了解决方案。

这个解决方案的好处：

- 你看到你的代码行为，你把它与你的期望相匹配。



次要效果

- 你会为自己找到虫子感到骄傲。

- 你的技能会提高。



你应该很快就会发现什么是错的。



[更新]

你知道抓起的瓷砖空的。

- 检查袋子瓷砖是不是空的。

- 检查从袋子里取出瓷砖时附加的东西。

- 检查附加内容，直到显示空的瓷砖。

Your code do not behave the way you expect, and you don't understand why !

There is an almost universal solution: Run your code on debugger step by step.
Mastering Debugging in Visual Studio 2010 - A Beginner's Guide[^]

The downside of this solution:
- It is a DIY, you are the one tracking the problem and finding its roots, which lead to the solution.
The upside of this solution:
- You see your code behaviour, you match it against your expectations.

secondary effects
- Your will be proud of finding bugs yourself.
- Your skills will improve.

You should find pretty quickly what is wrong.

[Update]
You know that the grabbed tiles are empty.
- Check that the bag tiles are not empty.
- Check what append when you grab a tile from the bag.
- Check what append until you display the empty tiles.
