    I do not see any label.getWidth() in the javadocs. But there is a static GenericLabel.getStringWidget(String) you can use.

    I can't seem to find that... ?

    Ok... well i'd going into it quite a bit... I found an image file in the minecraft.jar of spout, so i looked into the font there.

    Every symbol is down in the image with a width of 8 pixels. so i am assuming it works by checking how much of those 8 pixels wide the letter really is. Then in between letters, there is a 1 pixel gap. Space bar is a 4 pixel gap (excluding the spaces on either side of the character)

    more info coming

    I dont know if this can help you but Bukkit already made a list of all characher widths here.

    i am saved! ok thanks, looking through it now

    Thanks so much, i came up with a slightly modified version, simply removing the chat character limit, and made the width a parameter set when the function is called.



    THIS VERSION WILL SPLIT WORDS HALF WAY, INSTEAD OF MOVING THE WHOLE WORD TO THE NEXT LINE...

    Code:
    package modified.org.bukkit.craftbukkit;
    
    public class TextWrapper
    {
        private static final int[] characterWidths = new int[] {
            1, 9, 9, 8, 8, 8, 8, 7, 9, 8, 9, 9, 8, 9, 9, 9,
            8, 8, 8, 8, 9, 9, 8, 9, 8, 8, 8, 8, 8, 9, 9, 9,
            4, 2, 5, 6, 6, 6, 6, 3, 5, 5, 5, 6, 2, 6, 2, 6,
            6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 2, 2, 5, 6, 5, 6,
            7, 6, 6, 6, 6, 6, 6, 6, 6, 4, 6, 6, 6, 6, 6, 6,
            6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 4, 6, 4, 6, 6,
            3, 6, 6, 6, 6, 6, 5, 6, 6, 2, 6, 5, 3, 6, 6, 6,
            6, 6, 6, 6, 4, 6, 6, 6, 6, 6, 6, 5, 2, 5, 7, 6,
            6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 4, 6, 3, 6, 6,
            6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 4, 6,
            6, 3, 6, 6, 6, 6, 6, 6, 6, 7, 6, 6, 6, 2, 6, 6,
            8, 9, 9, 6, 6, 6, 8, 8, 6, 8, 8, 8, 8, 8, 6, 6,
            9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9,
            9, 9, 9, 9, 9, 9, 9, 9, 9, 6, 9, 9, 9, 5, 9, 9,
            8, 7, 7, 8, 7, 8, 8, 8, 7, 8, 8, 7, 9, 9, 6, 7,
            7, 7, 7, 7, 9, 6, 7, 8, 7, 6, 6, 9, 7, 6, 7, 1
        };
    
        private static final String allowedChars = net.minecraft.server.FontAllowedCharacters.allowedCharacters;
    
        public static String[] wrapText(final String text, int CHAT_WINDOW_WIDTH)
        {
            final StringBuilder out = new StringBuilder();
            int lineWidth = 0;
    
            // Go over the message char by char.
            for (int i = 0; i < text.length(); i++)
            {
                char ch = text.charAt(i);
    
                // Figure out if it's allowed
                int index = allowedChars.indexOf(ch);
                if (index == -1)
                {
                    // Invalid character .. skip it.
                    continue;
                } else
                {
                    // Sadly needed as the allowedChars string misses the first
                    index += 32;
                }
    
                // Find the width
                final int width = characterWidths[index];
    
                // See if we need a linebreak
                if (lineWidth + width >= CHAT_WINDOW_WIDTH)
                {
                    out.append('\n');
    
                    lineWidth = width;
                }
                else
                {
                    lineWidth += width;
                }
                out.append(ch);
            }
    
            // Return it split
            return out.toString().split("\n");
        }
    }



    THIS VERSION WILL NICELY KEEP WORDS ON THE SAME LINE, UNLESS THE WORD IS LONGER THAN THE WIDTH OF THE BOX OF COURSE.
