CST 112 Exam #1 (q1.pde)

CST 112 Exam #1

Starting with a copy of your project #1 code (submitted in your folder on a .pde file named p1) follow the instructions below, and submit your code for this exam on a .pde file named q1. Click this link to view instructions for Project #1:

Global variables in project #1 were similar to this example:

//// GLOBAL DECLARATIONS //// // (x,y) coordinates of hero, dog, etc. float bobX, bobY, bobXspeed, bobYspeed; float muttX, muttY; float cyclopsX, cyclopsY; float sunX, sunY, houseX, houseY, treeX, treeY, horizon; int score=0;
Of course, your declarations will be different
(using first letters of your own name for "hero" & "dog" -- rather than "Bob" & "Mutt") .
However, there is no need to change any of your variable names!

Please note that modularity and readability are important factors used in grading.

//// EXAMPLE of modularized draw() function //// void draw() { scene(); action(); messages(); }
The draw() function should call other functions to do the actual sketching; avoid calling graphics functions such as rect(), ellipse(), triangle(), fill(), etc. from within your draw(...) function.

Add these features to a copy of your p1 code (as illustrated in the Screen Shots):

Action:

Night & Day: Change between day and night, whenever sun (or moon) exits on the right,
- Yellow sun crosses a bright-blue daytime sky.
- Pale full-moon crosses a dark night sky.
Moving Bob: The hero should move as in Project #1, bouncing off the left and right sides, bottom, and horizon. Whenever the hero "bounces", add one point to the score (see below).
Monster: Add a one-eyed "monster" who slowly chases after hero ("Bob" & "Mutt") -- but only when it is nighttime. (The monster is slower than the hero, and moves only at night. The monster does not move at all when it is daytime.)
Catching Bob: If the monster is moving (at night only!), and comes near Bob (distance less than 50 pixels), reset Bob to the house, reset monster to right side, and deduct ten points from the score..

demo code
For illustration only; do NOT copy this code).

Animation:

Add 2 legs to the monster, animated to slant left or right as it moves.

Scene:

Change the house color from Red to Purple, with a door on the right and THREE narrow windows on the left.
Using a for loop, add a row of pink flowers on the horizon, evenly-spaced, starting at the right side of the house.
Using a while loop, add a row of brown rocks, near the bottom.
Draw a red ladder on the left, descending from the horizon to a point about 50 pixels above the bottom.
Display a "score", which changes as described above.
- Add one point, whenever the hero "bounces" (off the left or right side of the sketch, or off the horizon or bottom).
- Subtract ten points when the monster catches the hero, at night.
- Add five points when Bob passes near the monste, in the daytime.

Events:

mousePressed():
When the mouse is pressed ("clicked"), move Bob to (mouseX,mouseY) .

keyPressed(): Take the following actions when a key is pressed:

key ==	Action:
'd'	Change to day
'n'	Change to night
'r'	Reset: Move Bob to the house. Move monster to lower-right corner.
'q'	Quit.
'b'	EXTRA CREDIT: When 'b' key is pressed, a starts dropping from beneath the sun, going faster and faster until it reaches the bottom or hists something. If it hits the monster, add 5 points to score and send monster away (to lower left right).

Be sure to save your code in your folder (as q1.pde) before you leave class, today.

Takehome Exam "r1"

Starting with a copy of your exam code q1 revise and improve the code, as necessary, and submit it on a .pde file named r1. before noon on Sunday 3/8.

READING ASSIGNMENTS: Read all of Chapter 7 "Functions" (thru page 137) before the next class.
Also, read sections 8.1-8.4 of Chapter 8 "Objects" (thru page 147), before the end of next week.
(We will skip Section 8.5.)
