Help for my little game....

**davidvoyage200** · 05-26-2003

Hi everybody,
now i am creating a little RPG game(It is still FAR from over).

But i have a little problem with the display....
it display text all at once instead of word by word(like in real RPG...
Can C++ do that??(Display word by word)

Also i would like to know how to display some text and then "clear" the hold screen and then display some other text again....just like "cls" in DOS to clear the whole screen....

I hope you understand what i mean, (sorry for my bad english...).

Here is my Program, there are no error, but as i say, you can see that by default, it displays the whole text at once and never clear the screen:

Code:

#include <iostream.h>
#include <fstream.h>
#include <stdlib.h>
#include <string.h>

typedef char string[25];
typedef string string2[5];
string2 inventory;

class Digimon

	string name;
	int health;
	int stamina;
	int atthp;

	Digimon(string="nothing", int=0, int=0, int=0);
	void SetValue(string, int, int, int);
	friend ostream& operator<<(ostream& out, Digimon& digi);

    void AttLost(int);
	void StaLost(int);
     friend void EvilVillage(Digimon&);
     friend void DigmonHouse(Digimon&);
     
};

You're gonna have to write your own function to output text character-by-character or word-by-word.

For clearing the screen, why don't you people read the FAQ?

**Iamien** · 05-26-2003

sorry X too funny

Click your link.... its not a 404 but its something just as funny for when you tell someone to read the fAq :P

**XSquared** · 05-26-2003

Heh. Oops.

Fixed the link.

**davidvoyage200** · 05-26-2003

ok thanks, but also, i would like to know how to display a text and then let the user press any key(Without display the message Press any key to continue), then it clear the text and display the following text....

**XSquared** · 05-26-2003

Again, read the FAQ. Just don't output the 'Press a key to continue' message.

**the Wookie** · 05-26-2003

yeah you dont have to post your entire program either..takes up room

you can try something like

void printmessage(const char *msg){

while(*msg){
cout<<*msg;
Sleep(/*time in miliseconds between each letter*/);
*msg++;
}
}

for Sleep() you need windows.h. but something like that

**davidvoyage200** · 05-26-2003

thanks "the wookie",
but i don't know how to get your funtion work...:

Code:

#include <iostream.h>
#include <windows.h>

void printmessage(const char *);

int main(void)

{
cout << "HI everybody, i have a cow"<< endl;
cout << "Whoo Hoo, DONUT"<< endl;
return 0;
}

void printmessage(const char *msg)
{
	while(*msg)
	{
	cout<<*msg;
	Sleep(1000);
	*msg++;
	}
}

Thanks

**XSquared** · 05-26-2003

You can easily write your own sleep function.

Code:

#include <ctime>

void sleep( long millis ) 
{
  long t = clock( );

  #ifdef _MSC_VER
      millis *= CLOCKS_PER_SEC / 1000;
  #else
      millis *= CLOCKS_PER_SECOND / 1000;
  #endif
  
  while( clock( ) < t + millis )
    t = t;
  
}

**XSquared** · 05-26-2003

With the Wookie's example you have to use printmessage( "whatever" ); instead of cout.

**davidvoyage200** · 05-26-2003

Thanks XSquared,
but i don't understand your function...(too difficult for me)

however i start get "the wookie" 's program work, please take a look.

Code:

#include <iostream.h>
#include <windows.h>

void printmessage(const char *);

int main(void)

{
printmessage("HI everybody, i have a cow");
cout<<endl;
printmessage( "Whoo Hoo, DONUT");
return 0;
}

void printmessage(const char *msg)
{
	while(*msg)
	{
	cout<<*msg;
	Sleep(100);
	*msg++;
	}
}

The problem with this is, it display the whole line, and around 5 seconds later, it display the other line.

But what i want is display each word every a period of time and not the whole line....

**XSquared** · 05-26-2003

In that case, you're gonna have to scan through and print from space to space.

Code:

void printmessage(const char *msg)
{
	while(*msg)
	{
		while( *msg && *msg != ' ' )
		{
			cout<<*msg;
			*msg++;
		}
		cout<<flush;
		
		Sleep(100);
		while( *msg && *msg == ' ' )
		{
			cout<<*msg;
			*msg++;
		}
		
	}
}

**davidvoyage200** · 05-26-2003

Thank Everyone, it works now

**davidvoyage200** · 05-26-2003

if some of you have time, could you please explain me line by line how the "printmessage" function work?
Especially this line:
cout<<flush;

Thanks again.
