Naming multiple instances and arguments in For Loop

This is the syntax for when you want to tell multiple instances to do the same thing but you don’t want to have to type the commands one by one.
With this setup you can just tell it once all you want it to do then stick in a for loop and it will run as many times as there are instances named and specified

for(var i:uint=0;i<4;i++){
this["pic"+i].buttonMode=true;
this["pic"+i].x=-700;
this["pic"+i].y=1100;
this["pic"+i].alpha=0;
this["pic"+i].mouseEnabled=true;
}

In Robotlegs if you are building a Flash Professional your syntax will be a bit different.
For instance if the items you are trying to target are within an Injected class you must create your naming string first and replace “this’ with the [Inject] public var name then the created string inside the brackets not concatenation  It will be more like you a writing in the form of KEY[VALUE].property = or KEY[VALUE].method().

var table:String;
var hover:String;

for (var i:uint = 0; i < 5; i++)
{
table = “table” + i;
hover = “coverHover” + i
view[table].buttonMode = true;
view[table].addEventListener( MouseEvent.MOUSE_DOWN, liftCover, false, 0, true );

view[hover].stop();
view[hover].visible = false;
view[table].addEventListener( MouseEvent.MOUSE_OVER, hoverCover, false, 0, true );
view[table].addEventListener( MouseEvent.MOUSE_OUT, offCover, false, 0, true );
}
