I have made a nearly complete textbox engine, and you can find it in the download list, by searching for "textbox". It can only print one line at a time, however, and I want to be able to do multiple lines without having to type a separate string for each line. How would I make a string wrap to a new line?

Use the function TextWidth() on a subset of your string obtained from the function left(), until it exceeds the length of the textbox, or whatever. Something like this.



void WrapPrint(int x, int y, int dest, int font, string t, int maxlen)

{

  int i;

  while(len(t) > 0)

  {

    i = 0;

    while(TextWidth(font, left(t,i)) < maxlen && i <= len(t))

      i++;

    i--;

    PrintString(x,y,dest,font,left(t,i));

    t = right(t,len(t)-i);

    y += FontHeight(font);

  }

}

This won't separate the string by words though.

Thanks, I didn't know if there was a function for the width of a string. Making it only wrap words should be pretty easy. :)

EDIT: I'll just redo it because I want to check when the next space is and junk like that.
