If you already have a note from me on Google Classroom that your homework is complete, you have these options:

• keep adding to your adventure game
• do something else with Python, or with p5.js, Blender or Tinkercad Codeblocks

New Adventure Game

Start here. Let’s study this program, and:

• Change the places (right now they are: airstrip, forest, cave, meadow)
• Add new places
• Add events that can give you inventory items or end the game

2021-04-16

Adventure Game: Improving the User Experience

Let’s make the game easier for the player.

• Let them answer with one letter: Where to? (B)each, or (G)rocery store?
• Convert responses to lower case: place.lower()
• Exit the game when they lose: exit()

2021-03-26

Adventure Game: Adding Randomness

Start here. We’ll add these features in class:

• award a randomly-chosen number of knowledge points (randint)
• randomize the messages that appear in the various game places (randint, choice, and if)

Optionally do the assignment in Google Classroom.

Adventure Game: More Practice with print, input and if

2021-03-12

Practice with print, input and if

day = 'Friday'
print('Hello, world! Today is', day)

name = input('Hi. Your name? ')
print(name)

answer = input('What is "hello" in Spanish? ')
if answer == 'hola':
  print('Right!')
else:
  print('Sorry, the answer is "hola"')

Once you are comfortable with those, please make something with p5.js, Python, Blender or Tinkercad Codeblocks.

2021-03-05

Python Dictionaries, Continued

Let’s get everyone to submit a correct program

If you have submitted a correct program, please make something with p5.js, Python, Blender or Tinkercad Codeblocks. Maybe you’d like to show something you make.

(Grade 6, in the classroom, experienced videoconference problems. We barely got through the “Hello, world” warmup.)

Current Weather Web App, Continued

Show Data on the Web Page

Find weather items from the data below, and add them to your web page.

coord {'lon': -122.1119, 'lat': 37.8961}
main {'temp': 12.59, 'feels_like': 10.04, 'temp_min': 11.67, 'temp_max': 13.33, 'pressure': 1024, 'humidity': 47}
visibility 10000
wind {'speed': 1.16, 'deg': 29}
sys {'type': 1, 'id': 3581, 'country': 'US', 'sunrise': 1612537726, 'sunset': 1612575374}
name Lafayette

In your index.html file you use pairs of braces to extract the elements you want. For example, {{weather.main.temp}} gives you the temperature. Can you find main and temp in the data above? {{weather.main.feels_like}} gives you the “feels like” temperature. Can you find main and feels_like above? How about {{weather.main.humidity}}?

How would you get the wind speed? That’s in a different section. {{weather.wind.speed}} gets you wind speed. What about wind direction (measured in degrees)? Sunrise and sunset?

Last Week’s Assignment

Questions?

Current Weather Web App

We will create a web app to show the current weather, using Python and the Flask web application framework.

2021-01-22

Create a p5.js program on repl.it demonstrating that you’ve met the objectives from 2021-01-08. Provide a link to your program in response to today’s assignment in Google Classroom.

p5.js, Continued from 2020-11-20

Exercise: Create something with 2D primitives

Log in to repl.it

Go to repl.it. Log in with a Google or other account.

Reference

• Drawing other 2D primitives: rectangles, ellipses, and triangles.

Objectives

• Become comfortable with the 2D (x, y) coordinate system and positioning shapes in it
• Understand stroke and fill
• Be able to place objects where you want them
• Use width and height so that the result scales correctly when the canvas size is changed
• Be able to use the p5.js reference to learn about p5.js

Advent of Code

About Advent of Code

Day 1 Puzzle

This Python code will get us started.

What we’ll learn while solving this problem:

• reading data from a file into a list
• looping over the contents of a list
• a loop within a loop
• adding numbers and comparing the sum to a number
• multiplying numbers

Grades 6–8

p5.js

Last week we practiced using JavaScript by itself, without p5.js. We now return to using JavaScript with p5.js.

Exercise: Create something with 2D primitives

Log in to repl.it

Go to repl.it. Log in with a Google or other account.

Reference

• Drawing other 2D primitives: rectangles, ellipses, and triangles.

Objectives

• Become comfortable with the 2D (x, y) coordinate system and positioning shapes in it
• Understand stroke and fill
• Be able to place objects where you want them
• Use width and height so that the result scales correctly when the canvas size is changed
• Be able to use the p5.js reference to learn about p5.js

Ideas

• A house
• A lake with cabins surrounding it
• A robot
• A musical instrument
• A person
• Birds in the sky

Grade 5

Tinkercad Codeblocks

Loops

We’ll create a row of several objects (pyramids, perhaps) by repeating a sequence of blocks. Then we’ll shorten the code by using a loop.

Grades 6–8

JavaScript Basics, in Coding Rooms

You don’t need to create an account. Please provide your real name instead of “anonymous something”.

• Creating variables
• Printing numbers, expressions, and variables
• Loops

Exercise: Create something with 2D primitives

If You Already Know All This

If you don’t need this lesson, please explore your own p5.js ideas and projects, or make something with Python, Blender or Tinkercad Codeblocks.

Progress

Grade 6: Technical problems, perhaps due to not using headphones. Little progress.
Grade 7: Got through the corners problem solution, and started on the exercise. Needed to turn off the camera of the person speaking in order hear that person without garbling.
Grade 8: Good discussion in show and tell/ask a CS question. Need to repeat the corners explanation.
