Educational goals of this lab - verify that every student can

• write some graphics code
• use random numbers
• use if statements
• use while loops
• get clicks from the user
• call functions in the same file
• work with their teammates to finish a project

INSTRUCTIONS:

(90 points) Team Problem:

Description of problem:

This program will be a guessing game "Find the Mystery Point". The program picks a random point on the screen (no fair picking one OFF the screen!) It allows the user to click on the screen to see if they can find the mystery point. The way they 'find' it is to come within 10 units of the mystery point, distance calculated by a function given below. The user is informed how many guesses they have taken so far and how far away they are from the mystery point. They keep clicking until they find it. The program tells them they found it.

(10 points) Problem #1: Complete a test plan.

• It is harder to test a program using random numbers.
• The answers will not be specific numbers, you need to describe what the program should DO. Describe what is output to screen (circles, text, numbers), what happens to the counter, the behavior of the program, e.g. waiting for another click, ending the game, etc.
• Put the answers as comments at the end of the program file.
• Do these FIRST before your program is written!

• Description	Input (number of clicks)	Expected behavior/output
  One click and game over	one click, within 10 units of mystery point	_____A._____
  One click, game not over	one click, farther than 10 units away from mystery point	_____B._____

  Note that the only way to have ZERO clicks is to hardcode the mystery point ahead of time, then the user clicks on it (not much of a game).

(10 points) Design

Design is given. Write three P's as usual.

• Build a graphics window, size is your choice.
• Use random numbers to choose a location on the window. Use them to build a Point, but don't draw it YET!
• Use a Text object to tell the user to click on the window.
• Get the user's guess by getting the Point that they click on.
• Draw a red circle at the point they guessed USE GIVEN FUNCTION
• Initialize a counter for the guesses, using what value??
• Use a Text object to display the counter with a label (draw it)
• Get the distance from the user's guess to the mystery point. USE GIVEN FUNCTION
• Make a Text object with the label "Distance" and draw it. Don't put a number in it yet.
• While the integer result of this distance is greater than 10,
  • use setText to output the distance (cast to integer) to the screen with label
  • get another guess from user
  • draw a red circle at the point they guessed USE GIVEN FUNCTION
  • count the guess
  • update the displayed counter
  • find the distance between the new guess and the mystery point USE GIVEN FUNCTION
• Report that the user found the mystery point
• Draw a green circle where the mystery point is - USE GIVEN FUNCTION
• Get another click so program will pause
• close window

Sample run:

• Start of game
• First click
• Second click
• End of game (from another game)

(70 points) Implementation:

• Include the given design and write the program.
• Two function definitions you paste into your program, BEFORE the call to main ("main()")

  You must use (call) these functions.

  def distance (pt1, pt2):
  #purpose: calculate the distance between 2 graphics Points
  #pre-conditions: two Point objects
  #post-conditions: returns distance using distance formula
     return ((pt1.getX() - pt2.getX())**2 + (pt1.getY() - pt2.getY())** 2) ** 0.5
  
  
  def drawPoint(pt, color, win):
  #purpose: draw a Circle of radius 3 at location given by pt with the color specified on the GraphWin win
  #pre-conditions: pt is a Point object which acts as center of circle, color is string, win is GraphWin object used to draw on 
  #post-conditions: a colored Circle of radius 3 is drawn on win, center at location given by pt
  
      c = Circle(pt, 3)
      c.setFill(color)
      c.draw(win)
  

• (5 BONUS POINTS)
  Change the program so that if you can't find the Mystery Point within 15 clicks, the program stops the game, shows you the Mystery Point and tells you you didn't find it.
• Submit this final program with your team members' names (the ones who were present at lab) using the Canvas link.
• Make sure that all members of the team understand the team result.

If you do not attend lab, you will NOT get the points for the Team Problem, even if your team does submit a solution!
