I have a fully working flash application, made in as3. Now i dynamicly added a movieclip and i would like to be able to erase that movieclip with a eraser of some sort, my goal is to be able pick up a sponge with the mouse and then start dragging over the movieclip and erasing the parts where i dragged over it.
Anyone who can help?
Looks like this might be what you're looking for:

Is the background behind the MovieClip always the same?
If so you can put an image of the background over the MovieClip you want to erase, and mask that image so it becomes invisible, then add a click listener that draws a circle in the mask when clicked. This way it'll look like the MovieClip is being erased.
With getPixel you can loop over the mask and detect the percentage of the MovieClip that has been erased, so you can remove the clip from stage when it's fully erased.

I have a movieclip moving and when I click him I want that appears a hole.
Its possible do that with actionscript? how?
If your hole should appear there the mouse clicks, you could create new Sprite, draw two circles (one bigger than your MovieClip, another at size of you hole, both at position of your click) using his graphics property. Fill it with any color. It should look like donut.
After that assign created Sprite as a mask for your MovieClip.
youMovieClipId.mask=createdSpriteId;
After that, you could add mask as child of your MovieClip, using
youMovieClipId.addChild(createdSpriteId);
Now created mask will follow your MovieClip.
I have several Movieclips which overlap one another, each one has a different graphic of a body part. I would like the user to be able to click on a body part and it highlights.
I've set up event listeners to detect a click on the movieclips and to then apply a colorTransform. The problem is that the top movieclip also gets selected, and not the one's below even though the movieclips have transparent BitMap (PNG) images in them.
Is there a way I can create the hotspots to support only opaque pixels?
I have a movie clip that I animate in my timeline.
At a certain point of my code I need to move that mc by actionscript and at another point I need it to do the timeline animation.
Now, I know that if I alter my movieclip through AS the timeline animations will be ignored further on, but I was wondering: is there a way to force the movieclip to follow the timeline tweenings back again?
No. Once you change a property, it is detached from the timeline.
One solution is having another movieclip inside that movieclip. That way, the timeline animates the main movieclip, but you can access the inner movieclip with a reference to it and do whatever additional transformations you want to it. How you do this will depend on what exactly you're doing, and you have to remember the transformations will "stack", but it works.
Is there a way in AS3 to make a the mouse ignore a certain movieclip? I need it to be on top of the other movieclips (due to transparancy effects), but have it in a way that allows clicking on the movieclips underneath it. I know about ".mouseChildren = false", but that only makes all the stuff inside that movieclip unclickable, but it still functions as a "barrier" on top of all the others buttons.
Is there a way to do this, or do I need to remove it completely ?
You need to set both .mouseChildren and .mouseEnabled to false before you can click on objects behind the MovieClip. This makes the mouse ignore the objects within the MovieClip and the MovieClip itself.

EDIT: Oops, didn't see that comment by Alex, sorry.
I have a function that displays an image on top of a movie clip but when you click another image, it of course replaces the current image. I don't know how to stop it from replacing the image, that way I can make an image appear and drag it over somewhere on the stage and then make a different image appear and drag that somewhere else, too. and what is the drag event for Actionscript 3.0.
Sprite or MovieClip startDrag() and stopDrag() methods.
also i don't understand the following:
function that displays an image on top of a movie clip but when you click another image, it of course replaces the current image
how do images get inside of your swf (library, embed, loader)?
why are they replacing each other on MouseEvent.CLICK?
according to my current vision of your problem Event.stopImmediatePropagation() or Event.stopPropagation() in MouseEvent.CLICK handler function may help
