Question

• how to make one object move to a specific point
  with animation in Actionscript ( not MXML code ) ?
  ( Flex 4.5 )

Answer 1

Built in animation effects will do the trick (this moves is to 200,200):

<s:Move id="myMoveEffect" xTo="200" yTo="200" target="{objectToMove}"/>

Then you can play it with a call like so:

myMoveEffect.play();

So, here’s a button that plays it, for example :

<s:Button label="move now!" click="myMoveEffect.play()"/>
