CST112 Project 4: Chapter 5

• Design some object of your own (this should be a different object than the ones you created for Projects 1, 2 and 3) that moves around the Processing output window as follows:
   
  • The size of the output window should be 300 by 400 pixels; however you should use the system variables height and width in any calculations and conditions so that all elements of the application should function the same way no matter what size the output window
     
  • The object should move both horizontally and vertically as well; when it reaches any of the output window borders it should reverse direction; for example if it reaches the left or right border, it should change direction horizontally; if it reaches the top or bottom border, it should change direction vertically (click the "Play Project 4" link below)
    
    ( You can receive a maximum of 8 out of 10 points if you complete this much of the assignment successfully )
     
  • For "additional points" do any or all of the following:
     
    1. For an additional ½ point of credit, set different colors for a major element in your object depending upon its location in one of the four quadrants of the output window; for example:
        
       • If it is in the upper-left quadrant of the output window, the color is red
       • If it is in the upper-right quadrant of the output window, the color is green
       • If it is in the lower-left quadrant of the output window, the color is blue
       • If it is in the lower-right quadrant of the output window, the color is black
          
       This is just a suggestion as demonstrated in the "Play Project 4" link below; you may use your creativity to implement this element in any way that you prefer
        
    2. For an additional ½ point of credit, change the shape of a major element in your object depending upon its location in one of the two halves of the output window; in the example:
        
       • If in the upper half of the output window, draw a ball
       • If in the lower half of the output window, draw a box
          
       This is just a suggestion as demonstrated in the "Play Project 4" link below; obviously you will not draw just a ball and a box since your object will be more complex than that; use your creativity to implement this element in any way that you prefer
        
    3. For an additional ½ point of credit, add a variable of type boolean to the application that controls the background color; the first time the mouse button is clicked, the background turns to a different color; the next time the mouse button is clicked, the background returns to its original color; this functionality continues to reverse each time the mouse button is clicked; update the value of the boolean variable in the mousePressed() method; alternately you may choose to use two background images and vary between the two each time the mouse is clicked
        
    4. For an additional ½ point of credit, when the mouse button has been clicked and the background color has changed to its alternate color (see #3 above), the fill color of the major area of the object should change to white (or some alternate color of your choice) only while it is in the lower-right quadrant (or some other area in the output window of your choice); when the mouse button has been clicked again, the object then should return to its normal color; this functionality continues to reverse each time the mouse button is clicked
        
  • Full credit (10 points out of a maximum of ten) will be given for successfully completing all parts of this assignment
     
  • Click this Play Project 4 link to view an sample application to see all the different effects (this is the full credit version with a "Smiley Face")
     
  • Insert the project number, your name, your e-mail address, the submission due date and one or two sentences that describe the sketch as comments at the beginning of the program (the same as you did for Projects 1, 2, and 3); additionally comment each of the groups of variable declarations as well as the sections of code

• Students may work on all projects in teams of two or three, and, if so, all students in the group must submit the same project to their own dropboxes in Blackboard.  In the text box's dropbox, as well as in the source code documentation (comments), state the name(s) of the classmate(s) with whom you worked.
   
• The completed project archived into a ".ZIP" file submitted electronically via an attachment to a Brightspace dropbox is due to Prof. Struck no later than 11:59 p.m. on the date listed in the course outline.
