Determining the movieclip assigned to a variable in an array AS3

Question

Please forgive my terminology, Im not educated on the proper.

Lets say I have multiple movieclip variables

var rblock1:MovieClip = new Rblock();
var rblock2:MovieClip = new Rblock();
var rblock3:MovieClip = new Rblock();
var yblock1:MovieClip = new Yblock();
var yblock2:MovieClip = new Yblock();
var yblock3:MovieClip = new Yblock();

I have them added to an array

var blockarray:Array = new Array(rblock1, rblock2, rblock3, yblock1, yblock2, yblock3);
var block

I want to create a for loop with an if statement that triggers if a variable is Rblock and not Yblock, for example

for each (block in blockarray)
{ 

    if (block==Rblock)
    { 
         trace("rblock");
    }

}

The issue is that obviously "if (block==Rblock)" doesnt work. How should this be written?

no im not trying to declare the clip, im trying to declare the class, the class is Rblock, the clip is rblock — Koden

To check if an instance belongs to a class you use if (block is Rblock) statement. — Organis

You apparently want to check if a block is red or yellow by checking against its class name. You can do it with this:

if (block is Rblock) {...} // yes, red

I have figured out a work around not really a perfect solution, which will only work for certain scenarios...

if each class has a unique trait you can identify it that way, for example...

if all variables defined by the Rblock class are wider than the Yblock class you could say

if (block.width>x) { trace(Rblock); }

Like I said this is only a work around though and only works for movieclip variables defined by classes that are different, if anyone has the actual solution please post

There are traits, namely class names, or also a common name of a superclass, you can perform checks against class name with if (block is Rblock) (in fact you check if this block is either Rblock or a descendant of Rblock this way, but normally you only check against a leaf class, so this is irrelevant).
