Copyright © 2003 Pearson Education, Inc. Slide 6-3 Objectives To understand how scripts work, why you need them, and how they are structured with the Lingo scripting language To learn how to write navigation scripts for a Shockwave project To learn how to control transitions with scripts To learn how to use scripts to control tempo To understand how to write scripts that perform if... then logic To examine some basic scripts that control sprites To learn how to create moveable sprites with drag-and-drop capability To bring these techniques together in your own Shockwave project

Copyright © 2003 Pearson Education, Inc. Slide 6-13 Summary Scripts are the key to interactivity in Shockwave projects. Navigation scripts let the user of your Shockwave project go to other parts of the experience. You can use scripts to control transitions between frames in your project. You can also control the tempo of your project. If... then logic is a key component of scripting for interactivity. Simple scripts allow you to control the visibility and location of sprites and to determine when two sprites collide. Drag-and-drop experiences enable the user to manipulate elements of your Shockwave project on the screen.
