Wednesday (2/2/11)

Warmup:

  • The following code is supposed to wrap the player in Robot.
from gasp import *
begin_graphics(800, 600, title="Catch", background=color.YELLOW)
ball_x=-10
ball_y = 300
ball = Circle((ball_x, ball_y), 10, filled=True)
set_speed(120)

while True:
    if ball_x<=0:   # REPLACE WITH COMMENT ON WHAT THIS & THE NEXT LINE DO 
         ball_x=800
    elif ball_x>=800:  # REPLACE WITH COMMENT ON WHAT THIS & THE NEXT LINE DO
         ball_x=0
    move_to(ball,( ball_x,ball_y))
    update_when('next_tick') # REPLACE WITH COMMENT ON WHAT THIS LINE DOES

end_graphics()
  • Copy and paste this code, and save it as a new program
  • Next, replace the comments
  • Then test the code
  • Finally, write answers to the following questions, then discuss them with your partner:
  1. What behavior do you see?
  2. Why do you think this is happening (what's your hypothesis)?
  3. How could you test your hypothesis? (think of two different methods)
  4. How can you fix the code (again, there are at least two methods)

Agenda:

Monday (1/31/11) - Tuesday (2/1/11)

Warmup:

  • Write a program that prompts the user for x and y coordinates between 0 and 200. Compare their input to a point at (75, 100). Tell the user if they are left or right of that point, and by how much. Likewise, tell them if they are below or above that point , and by how much.

Agenda:


Monday - Tuesday (1/24/11 - 1/25/11)

Agenda:

  • Continue working on Pong - aim to be finished this week.
  • Work on Robot game. Use the 8.8 version of Catch!

Thursday - Friday (1/13/11 - 1/21/11)

Agenda:

  • Begin working on Pong. Use the 8.10 version of Catch!

Warmup:

  • Without using the computer, what does the following code display?

begin_graphics(width=800, height=600, title="Question 23")

x = 0
while x < 100:
  Circle( (400, 300), x )
  Line( (x, 0), (400, 300) )
  x = x + 10

update_when('key_pressed')
end_graphics()
