hi all,
i’m trying to figure out how I can render a given char* as centered text
i use this call currently :
SDL_Surface *msg1Sur = TTF_RenderUTF8_Blended_Wrapped(msg_font, msg, msg_color, screen_width);
in which msg_font is ptr to a TTF_Font object, msg is a char* ptr, msg_color is a ptr to an SDL_Color object and screen_width is calculated as the width of the current SDL window
msg is usually 3 to 6 lines of text, generated from internal code (so NOT read from an RTF file or something like that)
I’m trying to figure out how I can make the text-align set to centered`
any help would be greatly appreciated !
Just set screen_width to a portion of your screen width, and place the
resulting surface more to the right? Or generate each line of the text
seperately (using just TTF_RenderText_Blended()) and align it yourself?

the first suggestion will still keep all text left-aligned, just on a smaller width 
the 2nd suggestion would require the feature to calculate the width of each line, so I can position them properly
I was hoping there was a way to do this via SDL_RTF, but that library seems not to be SDL2 compatble (and contains no XCode nor VisualC project file… which I need both)
thanks for the reply anyway !> Just set screen_width to a portion of your screen width, and place the resulting surface more to the right? Or generate each line of the text seperately (using just TTF_RenderText_Blended()) and align it yourself?

With TTF_sizetext you can get the width of the text using a certain font,
without generating a surface. You can also just generate the surfaces if
you already know where the newlines are, and then just ask the width of the
generated surface (surface->width or something iirc.)
