It certainly works if the type matches up, but it runs faster/is more
optimized if you do strongly type myObj.
The other thing that would probably speed up execution is if you assign
myObj.menuSquare_mc to a local variable. It takes more time to do the dot
lookup on the item you're referencing each time than if you'd do the lookup
once and use the local var to reference it. If you intend to reference a
variable more than a few times, store it in a local var.
You can do it the other way, but I've found it's a pretty good habit to get
into as you don't have to change your methodology once you're working on
projects that are iterating through a lot of data. The most obvious example
is if you define a variable like "arrayLength" equal to array.length and use
that in your for loop, you get a performance gain:
var arrLength:uint = array.length;
for(i:uint=0;i<arrLength;i++){
}
//runs faster than
for(j:uint=0;j<array.length;j++){
}
This is because you're doing that dot lookup with each iteration in the
second example. But I digress.
The other benefit to this practice is if you're using a tool like Flex
Builder or FDT or FlashDevelop or whatever, you can get code hinting on your
now strongly-typed vars which can speed development, though less so in this
case since you're passing TweenMax an object.
Also with strong typing, the compiler will throw compile-time errors which
shortens the debugging path.
So here's how I'd do your example, I suppose:
function leftmenu($e:MouseEvent ):void {
var myObj:MovieClip = $e.currentTarget as
MovieClip; //you don't necessarily have to use the
'as' part, but specificity is a bonus when you're passing these things
around.
var mySquare:MovieClip = myObj.menuSquare_mc as MovieClip; // or
Sprite or whatever.
switch($e.type){
case "mouseOver":
TweenMax.to(mySquare, .3, {alpha:.06,
delay:0,ease:Sine.easeOut});
TweenMax.to(myObj, .3, {x:60, delay:0,
ease:Sine.easeOut});
TweenMax.to(mySquare, .3, {x:-60, delay:0,
ease:Sine.easeOut});
break;
case "mouseDown":
trace(myObj.name <http://e.currenttarget.name/>);
break;
case "mouseOut":
TweenMax.to(mySquare, .3, {alpha:0, delay:0,
ease:Sine.easeOut});
TweenMax.to(myObj, .3, {x:30, delay:0,
ease:Sine.easeOut});
TweenMax.to(mySquare, .3, {x:0, delay:0,
ease:Sine.easeOut});
break;
}
