What's the difference manipulating display object position?

I have 2 possibilities. It looks like these are the same (or I'm wrong). Which is better and why?

 var quest1:DisplayObject = FrameCanvas.baseCanvas.addChild(app.questionmark1); // 
 quest1.x = posX; // 
 quest1.y = posY;   //

or

 app.questionmark1.x = posX;
 app.questionmark1.y = posY;
Solution

  • In the first example quest1 is a reference to app.questionmark1 which you are adding to FrameCanvas.baseCanvas and then updating its x and y.

    In the second example you are directly setting the x and y on app.questionmark1.

    Both work to update app.questionmark1's x and y properties, but in the second example app.questionmark1 may not be on the stage unless you added it somewhere else in the code.

    The second example is better because there's really not a reason to store a reference to app.questionmark1 as quest1 as you already can access it by app.questionmark1.
