How to Create a Vapor Effect in Flash CS3
Flash CS3 is an animation program that is developed by Adobe. This is the same company that makes other popular software such as Premiere and Photoshop. Creating a vapor effect is easy, as you're simply creating a hazy look to put over the movie. It's almost like adding a slight fog to the movie. This can be done to add realism to the animation or help illustrate the background of the animation. If you're willing to invest a little time, you can create a nice vapor effect.

1
Launch Adobe Flash CS3. When the program opens, under the words "Create New" click on "Flash Document 2.0/3.0." The difference between the types deal with coding only. Either one will work for this project.

Select a light blue color by clicking on the square next to the icon that looks like a bucket tipped sideways (this is the "Fill Color" tool). Click on the Rectangle tool on the Tool palette to the left. Drag it to make a rectangle just big enough to cover your entire stage (the white square in the center of the flash animation).

Move the mouse over to the Tools palette and click on the Selection tool. It looks like a black arrow icon and is in the top left corner. Click once on the square you just created. Click on "Modify" and select "Convert to Symbol."

In the dialog box that pops up, name your symbol. Under "Type," select "Graphic" then click "OK."

Reselect the Select tool. Click once on the square. At the bottom right, under the "Properties" tab, is a drop-down menu that says "Color." Click on this and select "Alpha." You will see a box with a percentage inside, and an arrow that can be dragged up and down will appear. The arrow and box control the opacity of the square. The lower the number, the more invisible the square you made becomes.

Pick a good percentage for your vapor effect. A good estimate would be between 10 and 30 percent. This will create a hazy vapor effect over your stage.
