Variables in textout

Variables in textout_ex...

I have the following line of code:

textprintf_ex(buffer, font, p1stuff.chp + "/" + p1stuff.mhp, 705, 501, color_text, -1);

I am getting errors concerning using the variables in the string. The variables represent current hit points and max hit points. How can I make this work properly?

Thanks in advance,
~~Jim~~

Are you using C++? It seems so. If you are using C:

char temp[512];

snprintf(temp, sizeof(temp), "%d/%d", p1stuff.chp, p1stuff.mhp);

textprintf_ex(buffer,
              font,
              temp,
              705,
              501,
              color_text,
              -1);

If you are using C++ and STL (not tested):

// textprintf_ex needs a char pointer, not a string, so I construct a
// temporary string and call c_str(), which returns "a pointer to a
// null-terminated array of characters representing the string's contents"
// according to the STL documentation.
textprintf_ex(buffer,
              font,
              string(p1stuff.chp + "/" + p1stuff.mhp).c_str(),
              705,
              501,
              color_text,
              -1);

Would this work with textout_ex as well?

Yes, or with any other function that needs a char pointer as argument.

void textprintf_ex(BITMAP *bmp, const FONT *f, int x, y, color, bg, const char *fmt, ...);

Try:

textprintf_ex(buffer, font, 705, 501, color_text, -1, "%d/%d", p1stuff.chp, p1stuff.mhp);

If the writing above has offended you, you've read it wrong.....fool.
And if you read that wrong it means 'All of the above is opinion and is only to be treated as such.'

font,
temp,
705,
501,
color_text,
-1);

... why in the world of jumping jehosephats would anyone do that?

textprintf_ex(buffer, font, 705, 501, color_text, -1, "%d/%d", p1stuff.chp, p1stuff.mhp);

Because it is 5:19 AM and at this hour I focus either on C++ or C

Do we need to point out that the syntax you used for textprintf_ex isn't even valid..?

That is Matthew's fault for not adding intellisense to the reply box
