show a variable on the screen?

da_cobra · 2001-11-25T17:48:20

ok I have this function that prints a text on the screen in my directx program but how can I use this function to also display a variable on the screen, because it would greatly help me if I could do that for debugging purposes void PrintText(char *text, int X, int Y, int bR, int bG, int bB, int tR, int tG, int tB) { if (G.lpDDSBack->GetDC(&G.hdc) == DD_OK) { SetBkColor(G.hdc, RGB(bR, bG, bB)); SetTextColor(G.hdc, RGB(tR, tG, tB)); TextOut(G.hdc, X, Y, text, lstrlen(text)); G.lpDDSBack->ReleaseDC(G.hdc); } } I use the function as follows : PrintText("text", 0, 0, 0, 0, 0, 255, 255, 255) ; this prints "text" on the left top of my screen with a black background and writen in white when I try to use a variable in the function it doesn''t work thanx in advance for any advice...

Btw, the problem with your previous post was that you forgot to include the ellipses in your parameter list:

int PrintText(char *text, int x, int y, int bR, int bG, int bB, int tR, int tG, int tB, ...  );

The ellispes (the three dots) are necessary.

ah ellipses are 3 dots :D
sorry didn''t know that (I''m dutch)

I just thought you meant with that "the rest of the variables in the function"

thanx anyway

The way *I* would do it USING YOUR FUNCTION....

char numstr[100];
sprintf(numstr,"%d",yournumber);
PrintText(numstr, 0, 0, 0, 0, 0, 255, 255, 255) ;

It works, but has the unfortunate side effect of requiring you to know the appropriate format string for every variable. That''s why I switched to streambuffers (and I love them!)
