Demo

Requires a simple plug-in downloaded from website

Plug-in adds new option when you create a project

Imports all necessary packages/libraries

Students only need to worry about ‘Source Packages’

All of the Alice classes are shown as Java classes.

This means…

you can do with Alice!!!!

Teach advanced Java concepts with ease (Sorting, Recursion, 2D Arrays, Dynamic Programming)

Implement a Text-Speech Alice Storyteller with JSAPI

Alice 3.0 mail interface for children using javax.mail

hmmm

a main method

initialize the program

Run the program

showInJFrame() displays the scene on a graphic canvas

The Alice World is 3D, with the center being the center of the World (0,0,0)

Without the ALICE IDE, we need to bemore professional with our placement ofobjects

A Position Class has been defined whichprovides an X,Y,Z coordinate

X-> subtracting moves rightY -> subtracting moves downZ -> subtracting moves towards camera

normally you will move and rotate objects using the Alice methods

I’m going to cheat a little A Quaternion represents rotations in 3D

space (a,b,c,d)

a: forward/backward rotation b: right/left turn c:right/left rotation d: haven’t taken math in 15 years

So far… we have the penguins each pushing a snowball a random distance… is the snowball in the water?

Do in order penguin1.push snowball1 a random distance

penguin2.push snowball2 a random distance

if snowball1 and snowball 2 are both in the water penguin1.swagger penguin2.swagger

else if snowball1 is in the water penguin1.swagger

else if snowball2 is in the water penguin2.swagger

else neither is in the water

try again…

if (condition is true) { execute statement block1

} else { execute statement block2

}

hasReceived is a <typed> method (function) that returns true if a snowball's location is within the radius of the holeInIce (a blue circle object in the scene), otherwise it returns false.

If hasReceived is true, the snowball is in the water and it should disappear (set opacity to zero)

You should have guessed by now that with our transition to Java comes the ability to have 2D and 3D arrays [something that any 3D world should have

Think of how painstaking it was to create an array of Sims in Alice 3.0. Now, let me demo.

public void sort(int[] x){ for (int counter = 0; counter < 10; counter++) { //Loop once for each element in the

array. for (int index = 0; index < 10 - 1 - counter; index++) { //Once for each

element, minus the counter. if (x[index] < x[index + 1]) { //Test if need a swap or not. int temp = x[index]; //These three lines just swap the two elements:

x[index] = x[index+1]; x[index + 1] = temp; } }}

Sorting elements in Alice is just a matter of replacing x with an object array and adding code to animate the move

Tired of textual Towers of Hanoi?

Bored with Fib Fib-Fib Fib-Fib-Fibonacci?

Bring Alice into the equation and in a few minutes have a Recursive Party

multipleScenesAlice NetBeans Project

One of the number 1 requests Alice 2 couldn’t handle. Storybook Alice tried, but was weak.

Still a little glitchy, but piece of cake in Alice 3.0

Also makes group collaboration a cinch

In my opinion, parallel programming grossly neglected by Ministry and us

Alice is natively threaded (Do Together) and it makes it natural to use this as a teaching tool

Can illustrate collisions, semaphores, etc
