1090: Migration issue: The onMouseUp event handler is not triggered automatically by Flash Player at run time in ActionScript 3.0. You must first register this handler for the event using addEventListener ( 'mouseUp', callback_handler).
1090: Migration issue: The onMouseUp event handler is not triggered automatically by Flash Player at run time in ActionScript 3.0. You must first register this handler for the event using addEventListener ( 'mouseUp', callback_handler)
i just added
addEventListener ( 'mouseUp', callback_handler) this line in the code but then it shows "Call to a possibly undefined method addEventListener."
so my question is how can i add this code in the program : addEventListener ( 'mouseUp', callback_handler);
the complete code is
