Computer ch. 2
Scenario
A description of the story, game or simulation; a description of the problem or task
Pivot point
A joint connection
Yaw
A left-right turning motion
Algorithm
A list of action to perform a task or solve a problem
Pseudocode
A loose version of the instructions that will eventually become program code
Describe what is meant by the term method
A method defines an instruction or series of actions for an object to do .
Arguments
A popup menu that allows you to select from a list: duration, style, asSeenBy, etc
Program
A set of actions that tells the computer what to do
Comments
A string of text in a program that does not function in the program itself but is used by the programmer to explain instructions.
Pitching
A tipping, rocking-chair kind of motion
Do in order
Actions must occur one after another
Do together
Actions that occur simultaneously
Instruction
An action to be performed
Visual storyboard
Beaks down a scenario into a sequence of major scenes with transitions between scenes
Which control statement is used in Alice to create a block of instructions that will occur in sequence when the program is run?
Do in oder
Occur simultaneously
Do together
Bug
Error in computer programs
What is computer programming resemble to artist goes through when creating stiff?
Have to plan the final product, producing such intermediate artifacts
Textual storyboard
Looks something like to-do list; ordered list of action; summarize several scenes
Nesting
One program statement is written inside another
What are the steps in writing an alice program?
Read the scenario, design, implement, test
Method
Segment of program code that defines how to perform a specific task
Synax
Statement structure and punctuation
Explain how synchronize the motion of two objects in Alice
The easiest way is using the vehicle property
Explain how to synchronize the orientation of two objects in Alice.
The easiest way is with the orient to instruction
Design
The plan for implementing the program
Orientation
The three-dimensional coordinate system that provides a sense of direction
Do together and do in oder are described as control statement why?
They are each statements that tell Alice how to carry out instructions in a program
Describe the difference between translation motion and rotational motion.
Translational- the movement of the center of an object Rotational- rotation around its center
Trial-and-error strategy
Trying several different methods to find what works best
Describe two major differences between visual and a textual storyboard.
Visual- include a snapshot of the scene and description of the scene Textual- like a "to-do" list, provides a description of the steps to be accomplished
Implement
Writing the program code
