AS3 variables handling by AVM/compiler/scope
- by jchmielewski
I have couple of questions about AS3 variables handling by AVM/compiler/scope
.1. This code in Flash will throw an error:
function myFunction() {
var mc:MovieClip=new MovieClip();
var mc:MovieClip=new MovieClip();
}
but it won`t throw an error in Flex (only warning in Editor). Why?
.2. How Flash sees variables in loops? Apparently this:
for (var i:int=0; i<2; i++) {
var mc:MovieClip=new MovieClip();
}
isn`t equal to just: var mc:MovieClip=new MovieClip();
var mc:MovieClip=new MovieClip(); because it will throw an error again as earlier in Flash, but in Flex in function not? Is Flash changing somehow my loop before compilation?
.3. Where in a class in equivalent to timeline in Flash - where in class I would put code which I put normally on timeline (I assume it is not constructor because of what I have written earlier, or maybe it`s a matter of Flash/Flex compiler)?
