Primitive functions and programmer-defined functions

All objects in Alice provide a variety of functions in addition to methods.

(This includes the world, the camera, the light, the ground, and objects created from the classes in the gallery.)

I will refer to them as primitive functions.

You can also create new functions and attach them to any of the Alice objects.

In this lesson, we will investigate:

• The use of primitive functions
• The creation and use of programmer-defined functions.
