Introduction to Alice

Upon opening the program called “Alice” I get a welcome to Alice message and options to click on tutorial, recent worlds, templates, example, text book, or open a world. When I click on example I get a list of six things to choose from, and I pick lightdemo and open.

In the upper left hand corner of Alice is the object tree with world as a main part to it, and under world are the object included in the object tree. In order there are five objects in the object tree, camera, red light which then has a point light part to it, green light which also has point light as a part, blue light that also has a point light part to it, and finally sphere_highpoly as the last object in the object tree.

The properties for each of the three lights red, green, and blue are similar in that they all contain the same properties but with different values. The red, green, and blue light properties include color, opacity, vehicle, skin texture, filling style, point of view, and is showing. When clicking on the different colors the three properties that change values are color, skin texture, and point of view. There are also seldom used properties which include ispivitshowing, isfirstclass, isboundingboxshowing, isboundingsphereshowing, emissivecolor, specularhighlightcolor, specularhighlightexponet, shadingstyle, eventstopascending, and opacitymap.

The methods tab is located next to the properties tab and the methods for each color are the same. The methods for each color include say, think, play sound, move to, move toward, move away from, orient to, turn to face, point at, set point of view, set pose, stand up, move at speed, turn at speed, roll at speed, constrain to face, and constrain to point at.

A function in Alice is pretty much a question about information in your Alice world that Alice answers. Five functions of the green light are proximity, size, spatial relation, point of view, and...
