I don’t understand that at all. I did exactly like what you’ve shown and it reports error like “1120: Acceess of undefined property “.

what should I put into the property of the movie clip.

I was just wondering why you are storing left, right, up & down and not using Keyboard.LEFT, Keyboard.RIGHT, Keyboard.UP & Keyboard.DOWN?

True. I guess I just copied pasted the first if statement, should at least be else ifs, but a switch would be the best for the job. Thanks!

Nice post! Thanks for writing this up. Just a little suggestion though… might be more efficient to replace your multiple if() conditional statements with a switch-case statement inside keyDownListener. That way you will perform a minimum number of checks every time the listener is called.

Hi Evans,

Great article! It seems like DJC is correct about Mac OS alt(option) key does not respond to the flashplayer. It works with firefox browser, but it does not work in Safari. Is there a way to fix that issue?

Thanks.

Seems the ALT key is intercepted by the OS or app (Flash, browser, etc) in many cases and thus does not generate an event.
