Hi Volpix,

I'll start by being completely honest... I don't know the answer to your problem... I can't work out how to paste this into CodeBlocks (kinda frustrating!

)

I'm a recent addition to the world of C++ you see, so I'll be banking on some of your advice in the near future too.

Just a suggestion to help you get some help... at the top of this forum is a notice (sticky) explaining the do's and don'ts for asking for help, and one thing we are requested to avoid is L337 5P3AK... if you catch my drift?

I'm not admin here or anyone important, I'd just like to see this bunny jumping too as I know I'd learn something from the finished product.

TurboPT · #3 11-Apr-2007, 22:59

For the 2nd problem, change the 'move' variable to be a two-byte array:

CPP / C++ / C Code:

  char move[2];

then call cin's getline() function to get the input into move:

CPP / C++ / C Code:

  cin.getline(move, 2);  // stores 1 character, plus a terminator.

then change the switch to only look at move's first character:

CPP / C++ / C Code:

  switch( move[0] ) // add index.

For the 1st problem, what system are you using?
[I fear a flame-spray coming from dave, davis, and/or waltp]
if windows, NOTE THAT THIS IS NOT PORTABLE... a.k.a M$-specific!
include stdlib.h, and calling system("cls") might be possible;

if you have another system [UNIX, LINUX], I've seen other posts that claim system("clear") for those, but I'm not 100% sure.

volpix · #4 12-Apr-2007, 06:57

oh... I am so happy!!... and so touched

there are people out there who are willing to help me.
to TurboPT, thank you very very much for your help. I am able to clear screen now (which make me jumping joyously nonstop). feel motivated

to continue writing the game now.... because I was really frustrated due to the problems. I am using Borland C++ and can I know why the clrscr() cannot work? and what if I want to input the move without pressing enter? anyway, thanks alot again.
to Silent, thanks for your advice too.

I did not look at the do's and don'ts before I ask for help. so, thanks for reminding me. I hope I did not make anyone angry.... I know what not to do now, appreciate your help.
and to 57 other members who had viewed my post,

thanks. I so like to be a part of this community.

TurboPT · #5 12-Apr-2007, 11:41

How old is your Borland compiler?

Here are some posts with more info. about clrscr(), and the header file conio.h: (concerning their non-standardness)
(by waltp) http://www.gidforums.com/showpost.ph...77&postcount=4
(by davekw7x) http://www.gidforums.com/showpost.ph...82&postcount=5

A couple of other things that I didn't mention, in the previous post, that you might want to consider:
1. Since you have headers without the .h extension, I didn't see this statement (typically found between the header files and main):

CPP / C++ / C Code:

  using namespace std;

Depending on the age of your compiler, this might error. However, there should have been other compile errors (again, depending on the compiler), especially with cout/cin without this statement.

2. You are working outside the bounds of the array with some of your loops.

The Borland compiler in use is most likely from before namespaces were introduced to C++. Adding the statement will probably cause errors.

And volpix, since it's obvious you haven't done this yet, please read the Guidelines. You must have missed them on the main C++ forum page.

I would just forget about using this function. It's nonstandard and it isn't working for you anyway. I think WaltP's method (as referenced earlier) works best.

I don't think you can do this. You have to let C++ know when you are done entering text. Otherwise how would the program know when to stop gathering data?

hi again, I am kind of busy doing my assignment and thaknks for those tips. however, i can use the clrscr() and getch() in other function(like interface and menu) so I am wondering why is it only malfunction inside the putcontrol function?

and when I face a few problems when I wanted to use setcolor function because in some function(displaybackground) I do not think I can use textcolor and cprintf. so when I try with the setcolor with the header <windows>,

CPP / C++ / C Code:

#include <windows>

void setcolor(unsigned short color)    //setcolor function
{
   HANDLE hcon = GetStdHandle(STD_OUTPUT_HANDLE);
   SetConsoleTextAttribute(hcon,color);
}

I got 5 errors such as (20,15): too many types in declaration, (20,16): { expected, (47,12): expression syntax, (54,15): too many types in declaration, and (54,16): { expected. all this do not appear until I put in the header file #include <windows>.

here is the game so far, still working on the time limit function as I do not know how to countdown. and I cut some irrelevant part like what the guideline say....

CPP / C++ / C Code:

#include <iostream.h>
#include <conio.h>
#include <stdlib.h>
#include <dos.h>

const int ROWS=50;       //declaration of constant for size of array
const int COLS=50;
char background[ROWS][COLS];  //declaration of array
int score;

//function prototypes
//to display introduction
void interface();
//to display menu
void menu();
//to draw hearts and diamonds
void drawhearts();
//to draw background
void drawbackground();
//to draw bunny as player
void drawbunny(int&,int&,int&,int&,int&,int&,int&,int&);
//to erase the bunny from array
void erasebunny();
//to display the background
void displaybackground();
//to ask player to input control
void putcontrol();
//to count score
//int countscore(int&,int&,int&,int&,int&,int&,int&,int&);
//to count down the time limit
//int timelimit();
//function for exit option
void endgame();


int main()   //start of main function
{
 _setcursortype(_NOCURSOR);

 menu();

 return 0;
}

   textcolor(13);
   cprintf("  ###     ###  #########  ###       #########  #########  ###    ### ########");
   cprintf("     ###     ###  #########  ###       #########  #########  ###    ### ########");

#include <windows>

void setcolor(unsigned short color)    //setcolor function
{
   HANDLE hcon = GetStdHandle(STD_OUTPUT_HANDLE);
   SetConsoleTextAttribute(hcon,color);
}

I got 5 errors such as (20,15): too many types in declaration, (20,16): { expected, (47,12): expression syntax, (54,15): too many types in declaration, and (54,16): { expected. all this do not appear until I put in the header file #include <windows>.

last night I go through the code and I hate myself for not realizing source of the problem earlier. I can use the <windows.h> header file now as the real cause is the name of the function: interface. it is actually a keyword,set aside for special purpose and cannot be use.

Problem solve!

sigh... the assignment is suppose to be pairwork and it is my partner's reponsible to do the intro (since she has no idea how to write a more complicated game) and a few problems I face is from her part of code. like the hearts thingy, she wants to have two kinds(hearts and diamond) which cause the marks to go haywire...

anyway, I solve the problem and I am sorry if I trouble anyone. The assignment will be summit on Monday.
