Title: Printing Variables
Post by: tpih on December 19, 2011, 09:46:00 am

I have searched around google but found nothing. How do I print variables to the screen? I have a score that I would like the user to be able to see.

Thanks

The question is not how to draw numbers on screen, but rather how to convert your numbers to strings that you can draw with SFML.

-> Google "c++ int to string" ;)

Can be as easy as:

Code: [Select]

char out[16];
int score = 5;
sprintf(out, "Score: %i", score)
sf::Text text(out);
renderWindow.Draw(text);

Nop, this code is C and unsafe.

There's only one good solution (with the current standard and no third-party libraries):

Code: [Select]

#include <sstream>

std::ostringstream oss;
oss << score;
sf::Text text(oss.str());

If your compiler supports C++11, you can simply use the to_string function.
