You want to show texts in a vertical orientation on Flash Player 10.

Solution

From Flash Player 10, you can use Flash Text Engine(aka, FTE), included in flash.text.engine.*. To show (and edit) text contents in Flash, you can do much much more than good and old TextField class.

“vertical orientation” is one of the great features FTE offers to us. I made a easy-to-use wrapper class for this feature. Check the code below.

And, here is a sample usage of “VText” class.

package 
{
	import com.hoora.view.VText;
	import flash.events.Event;
	import flash.display.MovieClip;
 
	public class Main extends MovieClip {
		public function Main() {
			addChild(new VText("Hello, 日本語！English words are shown like this. 日本語は縦書きに表示されます。", 80, 180, 0x005596));
		}
 
	}
}

And the result is,
