how can i animate  falling object ?

#2

Can you provide more details?  Is this a physics object (causing it to fall)?  What kind of animation do you want it to do?

Rob

#3

yes sir… its falling object with the use of physics…

i want my object like to blink2 and big small big small…

something like that…

You can probably use transitions for this.   See the transition library: http://docs.coronalabs.com/api/library/transition/index.html

If you’re going to use the enterFrame listener you probably don’t need the transition.to.  If you’re going to use the transition.to then you would change the scale and alpha in the transition parameters.
