  • This is a solo lab that you must complete your self but with some guild elements.
  • You may discuss the code with other students for this lab.
  • You must type all the code yourself and not copy from another student or source.
  • You may get sound files and images from other guild members.

Lab Specifications

  1. Make sure you have completed the exercises from lesson 10 and lesson 11.
  2. Complete the Chapter 9 exercises in CodeLab. These are review exercises and you have all the information needed to complete them. If you have questions, please contact the instructor for help.
  3. Scan the textbook chapter 10 to get an overview of the material.
  4. Complete the in-chapter exercises 10.1 through 10.34 that are listed throughout chapter 10.

    You can download the starting files from: Book scenarios.

  5. Read the textbook as you progress through the chapter to enhance your understanding and follow the exercise steps exactly except for the following changes:
    1. Exercise 10.1: name the scenario "my-test" (without the quotes).
    2. Exercise 10.13: use another sound file if you do not have access to a microphone.
    3. Exercise 10.15: send each guild member your picture and a recording of you saying something. Compile the images and sounds from at least two guild members, in addition to yourself, into your scenario.

    6. For those exercises steps that have a text answer, put the text in the README.TXT file for the scenario (Scenario > Scenario Information). The README.TXT is automatically turned in as part of the scenario. For example:
      Exercises with Text Answers
      10.7: mousePressed, mouseClicked, mouseDragged, mouseDragEnded, mouseMoved, getMouseInfo
      (more answers needed...)
      
  6. Upload the completed "my-test" scenario to Canvas as explained in the section of this document: Deliverables.

Deliverables

CodeLab is submitted automatically, but other lab work must be submitted as described below.

  1. On your computer, create a folder for the lesson exercises named "lesson" (no extra characters) and place all the exercise files from lesson 10 and lesson 11 into this folder. There should be four scenarios in the folder:
    1. asteroids-2b, which is the culmination of the lesson exercises completed during lesson 10 for the scenario.
    2. Loops and Counting from the Midterm 2 Review Supplement
    3. array_colors from the Midterm 2 Review Supplement
    4. shaper from the Midterm 2 Review Supplement
    .
  2. Create a second folder named "tutorial" (no extra characters) and place the scenarios from this lab into the folder. Do not include any files from previous labs. There should be one to three scenarios in this folder:
    1. my-test starting with exercise 10.1
    2. color-test starting with exercise 10.36 (optional)
    3. smoke starting with exercise 10.39 (optional)
  3. Create a zip file containing both folders, "lesson" and "tutorial", and submit the zip file to the Lab 11 slot of Canvas.

If you have any questions or find an error in the above files lists, contact the instructor right away.

Please do not add any extra characters to the above folder names. Also, do not put any spaces or special characters like #, : or $ in zip file or folder names.

Your crafted code must work as submitted. Remember to test and double check your files before and after submitting them. If you make a mistake, you can resubmit up to the deadline but must resubmit all your quest files.
