Weird console game logic error...?
(WinXP, Borland C++ Free Command Line Compiler)
Ok, I made a short console game, you can move a dot around the screen. But, my barriers only work for up & down, left and right dont work for some odd reason. I have looked all around my code, and I tried swapping their values, but I dont understand why the barriers dont work, its just a simple if() function...
Well heres my code, its actualy pritty short:
Code:
#include <windows.h>
#include <iostream>
#include <conio.h>
using namespace std;
enum {
ESC_KEY = 27,
UP_ARROW = 256+72,
DOWN_ARROW = 256+80,
LEFT_ARROW = 256+75,
RIGHT_ARROW = 256+77
};
int get_arrow();
HANDLE h = GetStdHandle ( STD_OUTPUT_HANDLE );
WORD Color;
CONSOLE_SCREEN_BUFFER_INFO inf;
CONSOLE_CURSOR_INFO Cur;
int main() {
COORD Pos;
COORD Pos2;
int Counter;
int c2;
int buffer;
int grid_x;
int grid_y;
clrscr();
GetConsoleScreenBufferInfo(h, &inf);
Color = inf.wAttributes;
Cur.bVisible = FALSE;
Cur.dwSize = 1;
SetConsoleTextAttribute(h, BACKGROUND_RED | BACKGROUND_INTENSITY);
SetConsoleCursorInfo(h, &Cur);
SetConsoleTitle("Hi");
for(Counter=0; Counter < 80; Counter++)
for(c2=0; c2 < 25; c2++) {
Pos.X = Counter;
Pos.Y = c2;
SetConsoleCursorPosition(h, Pos);
if(Counter == 10 && c2 == 13)
cout << "*" << endl;
else
cout << " " << endl;
}
Pos2.X = 0;
Pos2.Y = 0;
SetConsoleCursorPosition(h, Pos2);
grid_x = 10;
grid_y = 13;
for(;;) {
buffer = get_arrow();
if(buffer == ESC_KEY) {
clrscr();
SetConsoleTextAttribute(h, Color);
exit(0);
}
if(buffer == DOWN_ARROW)
if(grid_y == 23)
cout << "";
else
grid_y++;
if(buffer == UP_ARROW)
if(grid_y == 1)
cout << "";
else
grid_y--;
if(buffer == LEFT_ARROW)
if(grid_y == 80)
cout << "";
else
grid_x--;
if(buffer == RIGHT_ARROW)
if(grid_y == 1)
cout << "";
else
grid_x++;
for(Counter=0; Counter < 80; Counter++)
for(c2=0; c2 < 25; c2++) {
Pos.X = Counter;
Pos.Y = c2;
SetConsoleCursorPosition(h, Pos);
if(Counter == grid_x && c2 == grid_y)
cout << "*" << endl;
else
cout << " " << endl;
SetConsoleCursorPosition(h, Pos2);
}
}
}
int get_arrow() {
int ch = getch();
if(ch == 0 || ch == 224)
ch = 256 + getch();
return ch;
}
I'm guessing I messed up somewhere simple, but I just cant find my problem.... I have looked at this four three hours, but I'm not getting anywhere, no matter what value I give it, it just lets me bring it off the screen... Any ideas?
Thank you very much in advanced!
