Display Variables Access Scope using timeline objects.

please like and post your questions : http://www.facebook.com/pages/FlashCS5-Tutorials/176320862386436

In AS2 it was very easy to access any variables from Parents and Childs using _parent or _root .

but after the enhancement that happened to the AS3 the change the way you can access variables from different scops using the timeline Movies or even thru a classes.

****access variables using time line Movies.

to understand how you can access a parent variables from child or vise-versa you need to create new AS3 document  and then create Circle Movie and name it "shapes_mc"  then inside this Movie Create another square  and Movie and name it "square_mc". so finally create a dynamic text name it "name_txt" then converted to movie and name it "textContainer_mc" as in the picture below:

so now on the stage create new variable in farm1 :
var Scope1 = "Scope1"
in the shapes_mc create another variables :
var Scope2 = "Scope2"
in the Square Movie create variable
var Scope3 = "Scope3"

* now I will show you how you can access these variables from different Movies by creating a buttons in each scope and in when the user click will trace the other variables from button scope.

• Stage Button Code :

stage_btn.addEventListener(MouseEvent.MOUSE_DOWN,TraceScopeHandler)
function TraceScopeHandler(e)
{
trace("Stage Variable --> "  + Scope1)
trace("Shapes Variable --> " + shapes_mc.Scope2)
trace("square Variable --> " + shapes_mc.square_mc.Scope3)
trace("Text Variable --> " + textContainer_mc.name_txt.text)
}

• shapes Button Code :

import flash.display.MovieClip;
var Scope2 = "Scope2"
shapes_btn.addEventListener(MouseEvent.MOUSE_DOWN,TraceScopeHandler)
function TraceScopeHandler(e)
{
var oStage:MovieClip = parent as MovieClip
trace("Stage Variable --> "  + oStage.Scope1)
trace("Shapes Variable --> " + Scope2)
trace("square Variable --> " + square_mc.Scope3)
trace("Text Variable --> " + oStage.textContainer_mc.name_txt.text)
}

• square button code:

import flash.display.MovieClip;

square_btn.addEventListener(MouseEvent.MOUSE_DOWN,TraceScopeHandler)

function TraceScopeHandler(e)

{

var oShapes:MovieClip = parent as MovieClip

var oStage:MovieClip = oShapes.parent as MovieClip

 

trace("Stage Variable --> "  + oStage.Scope1)

trace("Shapes Variable --> " + oShapes.Scope2)

trace("square Variable --> " + Scope3)

trace("Text Variable --> " + oStage.textContainer_mc.name_txt.text)

}
