Assignment

It would be really cool if we could control our avatars via the command line and make them perform certain actions. To do this, we will write a program that allows a user to write a set of commands using flags to control the avatar. Flags can be chained together to create more complicated commands.

Your command line interface needs to work with the following flags:

-create: Creates a new avatar and prints an ID for that avatar to the screen, also makes this avatar the current avatar.

-loc x y : Changes the location of the current avatar to the location specified by x and y

-up p : Moves the current avatar up by p pixels

-down p : Moves the current avatar down by p pixels

-left p : Moves the current avatar left by p pixels

-right p : Moves the current avatar right by p pixels

-color c : Changes the avatar to the color denoted by c

-shutDown id: Hides the current avatar and does not allow us to interact with it any more (assuming the id is valid, otherwise nothing happens)

-quit : Kills the program

-changeTo id: Changes the avatar indicated by Id(assuming Id is valid, otherwise nothing happens)

Some example inputs your command line interface needs to handle are as follows:

//Create a new avatar, place it at 100, 100 and set its color to

//red

-create -loc 100 100 -color red

//Change control to avatar 3 and set its color to blue

-changeTo 3 -color blue

Important: For the avatar, our teacher is using an alternate library called wheelsunh. But I don't need you to create the avatar for me. Simply implement the methods will do.

However, this library is incredibly simple and I will show you the code to create an circle here so you can use these in the methods.

Ellipse testcircle = new Ellipse(); //Ellipse is shape type. testcircle is the shape name.

testcircle.setLocation(100,200); //setting the location of testcircle to x= 100, y = 200.

testcircle.setColor(Color.RED); //self explanatory.

testcircle.hide() //this hides the circle, which can be used for shutdown method mentioned above.

Thank you very much for your help!
