I wrote this code so that random colors will appear on the text and "blink" every second(more or less),
but I can't seem to make it not blink *BLACK* , *BLACK*.
The code
CODE
if(color!=0)
is suppose to work, am I wrong?

Heres the entire code:

CODE
     while(color)
       {
       if(!kbhit())
     {
        randomize();
        color++;
        if(color!=0)
          {
            setcolor(color);
            delay(800);
            outtextxy(215,450,"Press any key to return");
            delay(800);
            setcolor(0);
            outtextxy(215,450,"Press any key to return");
          }
     }//if
       else
     {
        clearviewport();
        menu();
     }
       }//while

I am not sure about the setcolor function, but I think that if you choose a color between 16 and 32 it should blink...

I am really not sure what you mean by:

the setcolor function is a 16 numbers that equale different colors from 0 to 15.
and i meant by " *BLACK* , *BLACK* " that the random color will be black and the perm black : setcolor(0);
so it's something like this :
BLUE, BLACK
YELLOW, BLACK
GREEN, BLACK

getting my point?

So basically you just don't want the color to == 0.

I think you would do better to use a little mathematics:
CODE

while (!kbhit()) {
Color = (Color + rand(10)) % 15 + 1;
setcolor(Color);
...
}


The value Color in this loop will never be equal to 0 but will always have a value in the range 1 - 15 (0 - 14, then add 1 shifts it to 1 - 15).

Ok thanks it works.
but another problem i seem to have is that i cannot re-enter the page i have this code in there.
theres a problem with the key entry i do.. it's as if the random key i press in order to return to the menu of the game is pressed always until i quit the game and run it again..
anyone has an idea how to fix this?
