A Script Object is a drawing Object that is named and has the 'Target' checkbox ticked.
A Sprite is also a Script Object ('Target' checkbox is not required), as is the main Scene.
A Script Object can have Event Handler and private functions associated with it. Such an Object becomes the basic element of scripting.
All Script Objects have Object properties. In addition, Text Objects can also have text field properties.
When the 'Target' checkbox is available and ticked, the Object is automatically converted to a Sprite. This conversion will cause grouped Objects and text to lose their Complex Effect behavior.
