Flipping the envelope. This looks like a difficult animation but in reality it is very simple. We will use two movie clips to make it appear that the envelope has flipped over.

We will continue to work on the envelope intro for our ecard in Flash CS4. Our next step is to setup the stage and the elements that we will animate to make it appear that the envelope flips over on to its back in anticipation for opening.

In this tutorial we will learn how to make a slide-in motion tween effect in Flash CS4.

This tutorial will teach you how to create an animated 125 x 125 pixel square button ad in Flash CS4.

We will add ActionScript to our button. This code will tell Flash to stop the animation on Frame 80 and listen for the button to be clicked. When the button is clicked, the ActionScript will move the animation on to Frame 81 and the second half of the animation.

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.
