More Animation Lab #

In this lab we are going to continue to experiment with SuperTurtle and exploring decomposition and abstraciton.

[0] Set Up #

💻 Go to your cs9/unit00_drawing folder.

cd ~/desktop/making_with_code/unit00_drawing/

💻 Clone your repo. This will copy it onto your computer.

git clone https://github.com/the-isf-academy/lab_more_superturtle_yourGithubUsername

Below you’ll see that the git clone command has a yourGithubUsername.
You need to replace this with your username
e.g. https://github.com/the-isf-academy/lab_more_superturtle_emmaqbrown

💻 In the Terminal, type the following command to open the lab folder.

cd lab_more_superturtle_yourGithubUsername

💻 Enter the Poetry Shell to start the lab. We will run this command at the start of each lab, but only when we are inside a lab folder.

poetry shell

💻 This lab uses a package called SuperTurtle. To use SuperTurtle in this repo, we must install it using poetry.

poetry install

👾 💬 Exiting the poetry shell
When you want to exit the shell, you can type exit or ^D

💻 Take a look at the files inside with: ls

animation_tree.py
experiment.py
tree_parts.py
shapes.py

[1] Tree Animations #

This mini lab is designed to be a pick and choose adventure for practice animating with SuperTurtle.

👾 💬 Documentation
For lab, we recommend referencing the previous lab repository, lab_superturtle, and the offical documentation.
📖 SuperTurtle Documentation: superturtle.readthedocs.io/en/latest/animation.html
The offical documentation has a lot of information, so be sure to ask a teacher and experiment if you have any questions.

💻 Let’s start by running animation_tree.py

python animation_tree.py

💻 Take a look at the code with: code .

The main animation loop is in animation.py.
It uses the shapes.py file and tree_parts.py from the modules lab.

💻 Fist, add a moon!

Look in shapes.py for a function you can use to draw the moon!
How will you move the moon across the screen?
- Reference the previous lab OR the documentation

💻 Now move the moon!

How can you use translate to move the moon across the screen?

💻 Edit the settings.py file. Add the abilty to easily customize the moon size and color

How do you use variables from settings.py in animation_tree.py?

TOTAL_FRAMES = 240
TREE_TOP_COLOR = (40, 112, 58)
TREE_TRUNK_COLOR = (100,40,0)

💻 Now, create a forest of trees!

You may keep the moon, or comment out the moon (command + ?)
You will need to use nested for loops and fly()

Hint ↕

You can customize a for loop by using additional parameters. In this example, the i starts at -200 and increases by 100 each time, stopping at 200.

for i in range(-100, 100, 10):
    print(i)

You can also do this with nested for loops:

for x in range(-100, 100, 10):
    for y in range(-100, 100, 10):
        fly(x, y)

Extension: Offset Trees ↕

How would you offset the trees?

[2] Deliverables #

⚡✨ For this lab, you should:
☑️ At then end of class, be sure to fill out this Google form.
💻 Push your code to Github
git status
git add file.py
git status
git commit -m "describe changes here"
git push

[3] Experiment! #

💻 In experiment.py, experiment by creating your own animation to create a new design using functions in shapes.py. We included the starter code from the documentation, but feel free to delete it and start fresh!

A few ideas…

a face with eyes that move
a car that moves across the screen
a llama with ears taht grow

💻 Explore using the additional functions available to the animation transformations in SuperTurtle. Experiment with:

debug = True?
last_frame
cycles
restore_state_when_finished() in movement
dashes, dots, and rainbow in stroke
the available easing options
