Controlling a Script's Flow Typically, actions in your scripts execute consecutively, from beginning to enda sequence that represents your script's flow. Using conditional logic, you can control this flow by scripting specific actions to execute o...

Reacting to Multiple Conditions The best way to understand conditional logic is to examine it in the context of a simple application. We will use some of the concepts we've learned to script a project that reacts to user interaction. In our proje...

Reacting to User Interaction So far, all we have done is output the user interaction using a simple trace command. Now we want to expand on that by calling a specific function for each type of user interaction. Specifically, we are going to move a...

Detecting the Edge of the Stage Now that we have our project working, we will add one final feature. You'll notice that in our current version of this project, the target clip keeps moving past the edge of the stage. Now we will add some condition...
