The Scene Editor replaces the Events area and the Editor area when you are in Scene Editor mode.

Question 18

There is only one Alice object gallery: a Local Gallery provided with the Alice software.

Question 19

Objects in the same class are virtually identical to each other, except that the values stored in some of their properties may be different.

Question 20

The Tumble tool creates a new instance of the same object.

Question 21

The Duplicate tool can change the size of an object.

Question 22

The Hello, World! program first appeared in a C language book written by two AT&T software developers, Brian Kernighan and Dennis Ritchie.

Question 23

Whenever you want to make a copy of an Alice world, particularly if you have made changes to it and want to keep the old world, use the Save A Copy feature, and give the new copy a different name.

Question 24

The code from methods and events in an Alice world can be saved on an HTML Web page, which you may then print, send as an e-mail attachment, or view like any other Web page.

Question 25

Alice 2.2 allows you to record the view in the World window while an Alice world is playing as a QuickTime Movie file (*.mov).
