Question

Using .getPixel() to Read Through a MovieClip

Hello Smart People!

I have two images, one overlayed exactly over the other. The image in front is what the user needs to see, but the user behind can be considered to be like a map with different fields of color on it representing different things.

What I am trying to do is that when the user mouses over the image, it reads (via .getPixel) the color info of the image behind which prompts certain messages to be displayed.

I am not having a problem with getting .getPixel() to work since when I just have the behind image (colored "map") showing, the color data for each pixel comes up as expected. But, when I overlay the top image, it shields the back image from being able to be "read" by my .getPixel function.

Is there a way to have a movieClip not "interfere" with movieClips that lay behind it in the stack?

Any help would be appreciated.

getPixel handles BitmapData, it has nothing to do with MovieClips. All you need to do is save this color map clip as a BitmapData object at some point, and then use getPixel to access this data. I am not even sure how you could be calling this method with a MovieClip.
