How do I implement word wrap?

Question

XNA has Spritefont class, which has a MeasureString method, which can return the Width and Height of a string. I\'m trying to understand how to create a method

Answer 1

To add to Alina's answer, here is an extended version of that function, that will also linebreak single words that are longer than maxLineWidth

    public static string WrapText(SpriteFont font, string text, float maxLineWidth)
    {
        string[] words = text.Split(' ');
        StringBuilder sb = new StringBuilder();
        float lineWidth = 0f;
        float spaceWidth = font.MeasureString(" ").X;

        foreach (string word in words)
        {
            Vector2 size = font.MeasureString(word);

            if (lineWidth + size.X < maxLineWidth)
            {
                sb.Append(word + " ");
                lineWidth += size.X + spaceWidth;
            }
            else
            {
                if (size.X > maxLineWidth)
                {
                    if (sb.ToString() == "")
                    {
                        sb.Append(WrapText(font, word.Insert(word.Length / 2, " ") + " ", maxLineWidth));
                    }
                    else
                    {
                        sb.Append("\n" + WrapText(font, word.Insert(word.Length / 2, " ") + " ", maxLineWidth));
                    }
                }
                else
                {
                    sb.Append("\n" + word + " ");
                    lineWidth = size.X + spaceWidth;
                }
            }
        }

        return sb.ToString();
    }
