[SOLVED] Splitting text over multiple lines - (and some spout?)

See posts 5 and 6 for the answer!


Heres the original post:

 

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

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

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.

It's there. Likely your API is out of date.

 

wouldn't doubt it, ill update now then
