I am trying to apply a color matrix filter to all movie clips in a movie. I would like to do this without knowing the instance name of any of the clips. Does anyone know a way to loop through all the movie clips of a scene regardless of the names or number of clips.

```auto
for (var prop in this) {
 if (this[prop] instanceof MovieClip) {
  this[prop].filters = new Array(myColorMatrixFilter);
 }
}

```

Thanks, that’s great code. It works perfect.

Here is what I ended up with.

```auto

import flash.filters.ColorMatrixFilter;
var theColorMatrixFilter = new flash.filters.ColorMatrixFilter();
var theBWMatrixFilter = new flash.filters.ColorMatrixFilter();

var bwFilters:Array = new Array(theBWMatrixFilter);
var bwFilterMatrix:Array = new Array(0.3, 0.59, 0.11, 0, 0, 0.3, 0.59, 0.11, 0, 0, 0.3, 0.59, 0.11, 0, 0, 0, 0, 0, 1, 0);
bwFilters[0].matrix = bwFilterMatrix;

var colorFilters:Array = new Array(theColorMatrixFilter);
var colorFilterMatrix:Array = new Array(1, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 1, 0);
colorFilters[0].matrix = colorFilterMatrix;
    
bwBT.onPress = function(){
    for (var object in _root) {
         if (_root[object] instanceof MovieClip) {
              _root[object].filters = bwFilters;
         }
    }
}

colorBT.onPress = function(){
    for (var object in _root) {
         if (_root[object] instanceof MovieClip) {
              _root[object].filters = colorFilters;
         }
    }
}

```
