Now we are to the point in our project where we will add the button which we will program to trigger the second half of the envelope animation. We will make an invisible button and put it right over the top of the stamp.

In this tutorial, we will continue working on the envelope animation for our Flash ecard project. We have already built the fly-in tween that moves the envelope onto the center of the stage. Now, we will create the fade-in animation for the Click on Stamp text message.

We will continue with the object-based tween that we started in the previous tutorial to make our envelope fly onto the screen, while flipping and rotating. It will stop in the center of the stage.

Keep the file size of your Flash project to a minimum by using external assets. These assets do not contribute to the download time. In this tutorial, we will learn how to use ActionScript 3 to load an external image into our main Flash movie.

In this tutorial, we will finish the portfolio slide-show in Adobe Flash Catalyst. If you have been following along, we have made our buttons and are ready to add the special effects.

Now that we have imported our portfolio project Photoshop file into Adobe Flash Catalyst, we are ready to work on the navigation for our portfolio. We will build the pages or states for our project and turn our imported graphics into button components in Flash Catalyst.

Open your PortfolioLayout.psd portfolio project file into Catalyst and let's take a look around. At first glance, you will see that the workspace is not as intimidating as the Flash workspace.

Adobe Flash Catalyst simplifies and enhances the design process, allowing the designer to take the design to the next level by adding the front-end interactive features such as buttons, text input boxes, image transitions and more.

Now that we have our storyboard and design elements ready, we are going to start working on the first part of the ecard envelope animation. The first thing we will do is make a motion path.

Here are a few things that you might need to know when working with the drawing tools in Flash CS4.
