Chp 1 Programming

Alice is a programming environment that programs characters & objects in a virtual world using 3-dimensional space with each object containing properties.

Anything that can be represented by data in the memory of a computer and manipulated by a computer program.

A step-by-step set of instructions that tells a computer how to perform specific tasks

Can be tangible or abstract

Describe the object, weight, location and direction

Programs that manipulate the properties of an object

Set of similar objects that each have the same properties and methods but may have different values (like might be taller)

Each individual object is called an instance

The process of adding an individual object to a world

Object orientated programming

Integrated Development Environment--a computer program that is used to facilitate the writing of other computer programs has a Text editor, debugger and object library

Alice interface

Computes & returnes a value

• Describe the object in some way
• color
• position
• weight

• Programs that manipulate the properties on an object
• ex:
• Turn

Values that are stored in the properties of any one object

• Has four object titles
• World
• Camera
• Light
• Ground

Shows properties, methods and functions

• Can be changed within other programs, but they cannot be changed or edited because their details are hidden
• No edit button

Example of Encapsulated

Methods are assembled here by clicking & dragging titles

Shows existing events & is used to create new events

• Consists of a condition, called an event trigger & the name of a method called an event handler
• Ex:
• Pressing the "s" key

Used to copy instruction tiles in Alice methods drag & drop it

To the left of the World window, shows the objects of the current Alice World

Software with events where user can manipulate with mouse & keyboard

Has an edit button and user can change behaviors
