SlideShow or Stages can be expanded greatly with scripts. Scripts can take influence on playing, and also enhance the user interface.
First of all: It goes deep into the "guts" of the SlideShow. You should already possess basic programming knowledge to get started with this functionality.
1. How do I use scripts?
To each SlideShow object, a script can be appended, which comes to execution at different times. A script is ultimately just a text file. The time that each part of a script is executed is determined by Hooks. A Hook is nothing more than a specially named function within the script. Using the Scripting development environment, you can assign a script to a SlideShow object or create new scripts.

A very simple example of a script might look like this. This example defines a movement path, e.g. for an image or text:
procedure OnExpandSlideShow(SlideShowObject: ISlideShowObject) begin var Moveable = SlideShowObject as IMoveable; if Moveable = nil then Exit; // Cancel, because object has no movement path Moveable.SetDefault; // remove existing path completely var Item: ITimeRect; // First movement mark (always present) Item := Moveable; Item.SetBounds(DoubleRect(0.25, 0.25, 0.75, 0.75); // half of the screen // Add second movement mark Item := Moveable.AddItem; Item.SetBounds(DoubleRect(0.0, 0.0, 1.0, 1.0); // fullscreen Item.SetTime(SlideShowObject.Duration div 2); // Time when the second mark should be reached end;
