Having trouble making a function do what I want.

Shamino · 12-07-2007, 09:11 AM

Okay, I'm trying to create a text interface with my console for a blackjack game, I'm trying to make a function called init_output to setup a sort of template for output where certain fields can be updated.

This is the structure defining the "menu" of sorts.
Granted it isn't pretty, but eventually I want to add some serialization to this class and make a text editor that can save these structures to the hard drive, so I can load masses of them for a text adventure or something.

Code:

struct text_menu
{
	typedef std::map<int, std::string> tmenu;
	text_menu()			//Construct Blackjack text interface
	{
		int id;			//declare ID for output item
		std::string output;		//declare the actual output item
		id = 0;
		output = "Dealer's Cards";
		text.insert(std::make_pair(id, output));
		id = 1;
		output = "--------------";
		text.insert(std::make_pair(id, output));
		id = 2;
		output = "Nothing Here.";
		text.insert(std::make_pair(id, output));
		id = 1;
		output = "--------------";
		text.insert(std::make_pair(id, output));
		id = 3;
		output = "Player's Cards";
		text.insert(std::make_pair(id, output));
		id = 1;
		output = "--------------";
		text.insert(std::make_pair(id, output));
		id = 4;
		output = "Nothing Here.";
		text.insert(std::make_pair(id, output));
		id = 1;
		output = "--------------";
		text.insert(std::make_pair(id, output));
		id = 5;
		output = "What would you like to do?\n1) Hit me\n2) Stay\n3) Fold\n";
		text.insert(std::make_pair(id, output));
	}
	tmenu text;
};

All I'm doing with that is creating a map of strings and ID's to those strings. I may want to make a list of 0's and 1's for every entry into the map so I know which items are dynamic, or updateable, and which items are static.

Here is the IO class that I will use to manage these structures in massive quantities (eventually), right now I have the structure hard coded but I've realized essentially it's a file type.

Code:

class IO
{
public:
	typedef	std::map<int, std::string> output;
	
	void update_output(int id, std::string update)
	{
		output::iterator index = coutput.find(id);
		(*index).second = update;
	}

	void init_output(text_menu text)
	{
		
	}

	void display_output()
	{
		for( output::iterator index = coutput.begin(); index != coutput.end(); ++index)
		{
			cout << (*index).second << std::endl;
		}
	}
	int get_input()
	{
		std::cin >> input;
		return input;
	}
	void clear_screen()
	{
		system("cls");
	}
	output coutput;
	int input;
	
};
#endif

While the update_output function strictly is for usage of the game to update certain complex strings like a players hand or something, if I had a list of 1's and 0's in the structure I could accomplish this better, because then I could return a variable to the system to automatically connect game updates with text updates and such.

Essentially though I'm having trouble with the init_output function. I need to copy the map in tmenu.text over to coutput, I've been googling copy stuff for maps but I havn't found anything that really explained it, can anyone help?

text_menu::text and IO::coutput are of the same type, both text_menu::text and IO::coutput are declared public -> Simple assignement could be used.
e.g.

Code:

	void init_output(text_menu text)
	{
		coutput = text.text;
	}

Wow, "that was easy"

Can I insert it rather than set it equal to?

So I can load multiple menu's into the coutput map.

Shamino · 12-07-2007, 10:22 AM

I'm having a problem with the output, with this function:

Code:

	void play_game()
	{
		dealer.shuffle_deck(deck);
		int gameloop = 1;
		io.init_output(tmenu);
		while(gameloop != 0)
		{
			io.display_output();
			gameloop = blackjack(io.get_input()); 

			io.clear_screen();
		}	
		
	}

For some reason it's not copying over all my dividers as you see I created here, are duplicate ID's not allowed?

Code:

struct text_menu
{
	typedef std::map<int, std::string> tmenu;
	text_menu()			//Construct Blackjack text interface
	{
		int id;			//declare ID for output item
		std::string output;		//declare the actual output item
		id = 0;
		output = "Dealer's Cards";
		text.insert(std::make_pair(id, output));
		id = 1;
		output = "--------------";
		text.insert(std::make_pair(id, output));
		id = 2;
		output = "Nothing Here.";
		text.insert(std::make_pair(id, output));
		id = 1;
		output = "--------------";
		text.insert(std::make_pair(id, output));
		id = 3;
		output = "Player's Cards";
		text.insert(std::make_pair(id, output));
		id = 1;
		output = "--------------";
		text.insert(std::make_pair(id, output));
		id = 4;
		output = "Nothing Here.";
		text.insert(std::make_pair(id, output));
		id = 1;
		output = "--------------";
		text.insert(std::make_pair(id, output));
		id = 5;
		output = "What would you like to do?\n1) Hit me\n2) Stay\n3) Fold\n";
		text.insert(std::make_pair(id, output));
	}
	tmenu text;
};

Any idea's? Here is the output:

Code:

Dealer's Cards
--------------
Nothing Here.
Player's Cards
Nothing Here.
What would you like to do?
1) Hit me
2) Stay
3) Fold

No, map doesn't allow duplicate keys.

Why don't you make a simple array (vector) of strings you want to print?

Shamino · 12-07-2007, 10:57 AM

Can I still search the vector using an ID? I guess the ID is the index? Because there are some items that I would want to reuse, like dividers for instance.

I could use string compare right?

But if you are re-using the same thing, surely you only need one, and it can have ONE unique ID - I appologize if this isn't really what you asked - I haven't read ALL of the code and text in the thread...

Well, you could have a vector of available strings:

Code:

vec[0] = " "
vec[1] = "This"
vec[2] = "is"
vec[3] = "a"
vec[4] = "sentence"
vec[5] = "."

And then you might have a vector of numbers that tell you which items to use in which order:

Code:

sentence[] = {1, 0, 2, 0, 3, 0, 4, 5}

Shamino · 12-07-2007, 11:14 AM

I'm having trouble getting the vector setup to compile right, it's mostly just synatx issues:

Code:

#ifndef IO_H
#define IO_H
#include <iostream>
#include <string>
#include <map>
#include <string>

struct text_menu
{
	typedef std::vector<std::string> tmenu;
	text_menu()			//Construct Blackjack text interface
	{
		std::string output;		//declare the actual output item
		output = "Dealer's Cards";
		text.push_back(output);
		output = "--------------";
		text.push_back(output);
		output = "Nothing Here.";
		text.push_back(output);
		output = "--------------";
		text.push_back(output);
		output = "Player's Cards";
		text.push_back(output);
		output = "--------------";
		text.push_back(output);
		output = "Nothing Here.";
		text.push_back(output);
		output = "--------------";
		text.push_back(output);
		output = "What would you like to do?\n1) Hit me\n2) Stay\n3) Fold\n";
		text.push_back(output);
	}
	tmenu text;
};

class IO
{
public:
	typedef	std::vector<std::string> output;
	
	void update_output(int id, std::string update)
	{
	}

	void init_output(text_menu text)
	{
		coutput = text.text;
	}

	void display_output()
	{
		for (int index = 0; index < coutput.size(); index++)
		{
		}
		/*
		for( output::iterator index = coutput.begin(); index != coutput.end(); ++index)
		{
			cout << (*index).second << std::endl;
		}
		*/
	}
	int get_input()
	{
		std::cin >> input;
		return input;
	}
	void clear_screen()
	{
		system("cls");
	}
	output coutput;
	int input;
	
};
#endif

That is the new text_menu structure and IO class.

I'm having trouble with the syntax for updating one of the elements, as well as the syntax for outputting the whole deal.

Any ideas?

Elysia · 12-07-2007, 11:20 AM

Code:

cout << coutput[index];

For update you can try:

Code:

coutput[id] = update;
