a programming language
a program written in this is much easier for people to understand than a program written in machine language
if a program contains even one of these, it cannot be translated into an executable program
this is the part of the Alice environment that holds a list of all the objects in the world
each object in an Alice world has these, which are values that specify the object's characteristics
this is a description of a particular type of object; you can think of it as a blueprint that objects may be created from
when an object is selected you see three axes displayed in or near the object, which indicate the objects orientation. This is the direction in which the blue axis points.
first- direction, second- distance/amount
the primitive move method requires two arguments. What are they?
calling the method
when programmers execute a method, which is what they commonly say they are doing..
this is a mistake that does not prevent the program from running, but causes it to produce incorrect results
Do in order
this is a structure that causes a group of instructions to be executed in the order that they appear inside the structure
a function returns a value back to the instruction that called the function
This is the difference between a method and a function
ask user for a number
This world function allows the user to enter a number, and returns that number
This primitive function returns the distance from one object's center point to another object's center point.
ask user for a string
This world function allows the user to enter a string, and returns that string.
the what as a string function
What world function do you use to convert a non-string object to a string?
world view window
what part of the Alice environment displays a view of the world, as seen through the camera?
graphical building blocks, into an editor fully functional programming statements that you can easily customize
color property and opacity
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?
object, its lowercase
In an Alice world, would the word dog be the name of a class, or the name of an object? how can you tell?
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.
variable is used to hold an argument that is passed to a method when the method is called.
function returns a value back to the instruction that called it, and a method does not.
The difference between a function and a method
commonly used by object oriented programming languages to distinguish an object from its methods, properties, functions, etc.
moves centerpoint of object to centerpoint of second object (this one is passed as an argument)
aligns axes of object so that all three point in the same directions as the axes of the second object (passed as an argument)
object is tilted so that is forward axis is aiming at the second object's center point (passed as an argument)
