Don't know why I can't update a Dynamic Text object with int
value( it should have converted to String).
My code is simple.
It change the content to a String variable which is concat of
strings and int. The strange thing is that I can trace() the
correct value in the output window but the text displayed is just
the string part. If i try to assign int to the score.text directly,
it display nothing. I am sure the code do modify the text of the
object because the original text is "Score:"
