3. Alice.org Visual programming environment Storytelling/movies
Game programming

4. Alice.org Makes it easy to do 3D movies and interactive animations
Fun and intuitive programming model
you can see the objects you are programming
Highly visual programming environment
don't have to memorize syntax
Why the name Alice?
she's the central character in Lewis Carroll’s classic children's story Alice in Wonderland

5. Alice FREE! http://www.alice.org Load and run a world
Names ending in .a2w are Alice programs
a2w is an abbreviation for alice 2 world
Two kinds of animations
Movie: passive user watches the animation
Interactive: active user interacts with keyboard and mouse
Chapter 1
Chapter 2

6. Basic Concepts in Alice
Virtual world: an animation is implemented in Alice as a virtual world
Object: basic entity in Alice that has features.
Dimensions and directions: each object in Alice has
Dimensions: height, width, depth
Directions: up, down, forward, back, left, right
Center of an object: at the center of mass
Objects can be retrieved from
Local gallery, or
Web gallery

7. Basic Concepts in Alice (cont)
Distance: distance between two objects is measured from the centers
Location: in a 3-D space, described by a triplet (x,y,z). The center of the ground is at (0,0,0)
Animation: you develop a set of commands (methods) for each of the object in your world to interact with each other, creating an effect of animation

8. Objects

9. Objects objects In Alice, an object is (usually) visible and it
has a name
may have sub-parts that are also objects
has properties such as width, height, color, location
can perform methods (actions) on command
has functions that allow programs to obtain information about the object

10. Objects Three dimensions: height, width, depth
Six degrees of freedom (types of movement)
3 moving:
forward/back
left/right
up/down
3 turning:
roll: sideways
around forward back axis
pitch: up/down
yaw: left/right

Shows you how to use the program

14. A Whole New World File > New World Templates tab
double click desired template

15. Add Objects
Click on “Add Objects” pick from gallery

16. Object Parts Objects may be composed of parts
they are accessible through the object browser (upper left)

17. Save your world File > Save World Saves as .a2w file
Save FREQUENTLY
Animation is processor intensive, can crash

19. Alice Techniques
The mouse is used to approximately position objects in the scene
Camera navigation is used to set the camera point of view
Object drop-down menu used for many things including
resizing objects
more precisely position objects in the scene
Quad view is used to position one object relative to another object

20. Alice is “real coding”
Alice Code Java Code

21. The Future: Alice v3.0
Been in development for almost a year; will release in 2008.
Driven by Caitlin Kelleher’s findings about storytelling
make movies (or videogames)
Real Java
Alice v3.0 is a Java IDE, based on eclipse
will see real Java (if you choose)
Drag & Drop or type -> it’s up to you!
Insanely high production values: as good as real video games
We are developing a textbook along with the system
Just as we did with Alice v2.0
Wanda Dann, Steve Cooper, Randy Pausch and Don Slater
EA has given us $300,000* and permission to use the characters and animations from “The SimsTM 2” in Alice v3.0

22. The First Public Demo of Alice v3.0 with the SimsTM!
