question

color property and opacity

answer

what is the name of the property that determines an objects color? what is the name of the property that determines whether you can see through an object?

question

class

answer

a description of a particular type of object, written in programming statements

question

classes

answer

what is stored in the Alice galleries

question

scene editor mode

answer

when you click the "add objects" button, what mode does Alice go into?

question

object, its lowercase

answer

In an Alice world, would the word dog be the name of a class, or the name of an object? how can you tell?

question

detail panel

question

variable

answer

a storage location that is represented by a name

question

string

answer

a sequence of characters

question

local variable

answer

belongs to a specific method. It can be used only by the method the variable belongs to. When a method stops executing, it cease to exist in memory.

question

Parameter variables

answer

variable is used to hold an argument that is passed to a method when the method is called.

answer

return values indicating the object's position relative to other objects

question

dot notation

answer

commonly used by object oriented programming languages to distinguish an object from its methods, properties, functions, etc.

question

move to

answer

moves centerpoint of object to centerpoint of second object (this one is passed as an argument)

question

orient to

answer

aligns axes of object so that all three point in the same directions as the axes of the second object (passed as an argument)

question

point at

answer

object is tilted so that is forward axis is aiming at the second object's center point (passed as an argument)

question

set point of view to

answer

makes location and orientation of object match the location and orientation of second object.
