Thread: help w/ invaderz game

I am making an invaderz game (nooone take my idea!!!!) im trying to make the top guy move (he wont ) here is the code:

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

int x = 10;
int y = 24;
int bx = 1;
int by = 5;
int bux;
int buy;
int lorr = 0;
int bull = 0;
int tmer = 0;

int main()
{
while(1)
{
gotoxy(x, y);
putch('^');
gotoxy(bx, by);
putch('-');
if (tmer == 10)
{
clrscr();
if (bx == 1)
bull = 0;
if (bx == 80)
bull = 1;
if (bull == 1)
bx = bx - 1;
if (bull == 0)
bx = bx + 1;
tmer = 0;
}
if (kbhit)
{
char movement = getch();

if (movement == 27)
break;
}
delay(1);
tmer = tmer + 1;
}
return 0;
}


please dont be shy!

heh, i solved the problem (use the switch case structure) but i cant get it to read the escape button, anyone know how to make the switch case structure read the button 'ESC'?

ESC's ASCII code's 27, but I don't know if that'll help w/o seeing your code...

but I don't know if that'll help w/o seeing your code...

You just have to change the


if (kbhit)
{
char movement = getch();

if (movement == 27)
break;
}


to


if (kbhit)
{
switch(movement)
{
case /*the code for ESC*/:
//Dunno how to exit the program
break;
}
}


theres the code for you

P.S. you have to declare movement b4 using the switch case structure

It's still not working when you put 27 in instead of /*the code for ESC*/? What is it doing?

I want it to exit the prog when you hit the ESC key

it appears that the conditions never change for the following
and therefore bx and by never change.....
do a print out of these and see...

Code:

	                if (tmer == 10) 
		{ 
			clrscr(); 
			if (bx == 1) 
				bull = 0; 
			if (bx == 80) 
				bull = 1; 
			if (bull == 1) 
				bx = bx - 1; 
			if (bull == 0) 
				bx = bx + 1; 
			tmer = 0; 
		}

Code:

if (kbhit) 
{ 
       switch(movement) 
       { 
             case 27: 
                  return 0;
                  break; 
       } 
}

that should exit.
(sorry about my crappy spacing [u cant use tab key in here)

nope, doesn't work, either that or its not reading the case structure...

heh me bad

I hope this helps... I have built a couple of console games using kbhit()....



when using kbhit()


you have to using something like this....


while( 1 )
{

while( !kbhit() ) //kbhit waits for noone
{
PerformGameFunctions();
}

int key = getch();

switch( key ){ exit... move screen items.. exit...whatever.....

case 72: myship.x += SPEED; break;
case 75: myship.x -= SPEED; break;

};


}


you can also look into GetAsyncKeyState( VK_? )

I am not sure if it will work in a non-windows program... though..
but I think it should...

heh, n/m the prob was that i did

if (khbit)
{
//bla bla
}

Instead of

if (khbit())
{
//bla bla
}

hehe you get the idea
