SDL_ttf not opening font
Author
I am deeply confused as to why this won't open the font:
arial.ttf is in the same file as the .exe but it just isn't working.
SDL_ttf is initialized.
Also I'm not sure how to find out the error because there's no console :3, I remember something about stdout or something along those lines from ages ago when I dabbled with SDL
SDL, at least the version I have, redirects cout to a text file name stdout.txt . It will probably be placed in the same folder as your executable, in the bin\debug path or whatever it is.
Or, you can do it yourself with std::ofstream.
More info on std::ofstream.

#include <fstream>std::ofstream errfile("my_error_file.txt");if(Font == NULL){ errfile << "error loading font: " << TTF_GetError() << std::endl;}More info on std::ofstream.

Ok, the problem was that arial.ttf was in the wrong folder, now don't get an error message.
The text won't render though;
