How to create custom Flash Masking Effect

Hey guys today we are going to make a custom flash masking effect by using adobe flash Cs3 professional.

1^st you need to create a blank action script 2.0 or 3.0 file.  Then you can set the document dimensions as you want.

After that draw your mask shape with black colour. You can use your own or basic shape. Then align the object to top right on document.  Convert it to movie clip and give the name as my_mc.  And set the register pointer as top right corner. (Here I’m using square as mask shape)

Now double click on it and go  move into the my_mc movie clip. Again convert the square into movie clip and name it inside_mc and set registration point as center point. go inside inside_mc  movie clip, now  you can animate your  mask as you wish. I’m going to use zoom in and out motion. But remember mask will not allow using alpha effect for your objects. So even you use alpha effect for your movie clip it will not display that effect.

Ok, now initial animation of  your masking is done. Go back into the my_mc and make copies of it. To fulfill your document area appropriately . but there is a problem to do that. Because u cant imagine the dimensions of inside _mc. To  avoid that go back into the inside_mc and create a square with same dimensions of your masking square.

After creating full mask you can see your mask inside the my_mc as below.

When you finished, you can simple remove the square that you have created inside th inside_mc. When you remove that others will automatically disappeared  (because we use the same copy of inside_mc). Then my_mc  should looks like below.

Now your mask is finished. You can use this mask in various styles by changing the motion, frame rate or key frames of time line. Some sample are shown below.
