2 STEP 1: SET UP THE SCENE In this step you will open Alice and setup the scene. To set up a scene you will pick a template, create objects from classes, and position the objects. You can also use a procedure to move an object in the scene. A template controls what the background of the world looks like, objects are things in the world, classes are the things that define objects or classify them, and a procedure is a step by step description of how to do something. Pick Template When you first start Alice 3 it will ask you to pick a template for your Alice world. There are lots of templates that you can use such as GRASS, ROOM, MARS. The template is used to set the ground and set other properties (characteristics) of the world. 1. Click on WONDERLAND. 2. Then click on OK.

3 Setup the Scene When you click the Setup Scene button you will be able to add objects to your scene. Objects are things in your scene such as people, trees, and animals. Objects know how to do things and have properties like a position. Objects will do the action in your Alice world..
