Creating Masks Masking is a way of selectively hiding and displaying content on a layer. Masking is a way for you to control the content that your audience sees. For example you can make a circular mask and allow your audience to only see through the circular area so that you get a keyhole or spotlight effect. In Flash you put a mask on one layer and the content that is masked in a layer below it. Masks can be animated and the content that is masked can also be animated. So the circular mask can grow bigger to show more content or the content can scroll under a mask like scenery whizzing by a train window. Define the Mask and Masked layers You ll create a rectangular mask that starts small and grows larger to cover the Stage. The resulting effect reveals the contents of the Masked layer slowly similar to a sliding door opening.
