Assignments > P1: Make an Interactive Animation

Due on Mon, 11/15 @ 11:59PM. 40 Points.

Project Starter Files

This assignment asks you to apply what you’ve learned to create an animated, interactive terrarium or aquarium. To get an idea of what you might make, please see the sample videos (as well as the animated gif below). Many (in fact most) of these samples have gone above and beyond the assignment specifications (and thus earned extra credit), but please know that meeting the assignment’s minimum requirements is sufficient for earning all 40 points. Please calibrate your implementation according to your experience level with programming (i.e. do more if you’re more experienced): you’ll get out of it what you put into it. See the rubric below to get a sense of how you will be evaluated on this assignment. Then, download the starter files (above).

Created by Rachel Smith (Berkeley City College)

Part 1: Create a make_creature function (7 points)

In helpers.py, create a custom function called make_creature that makes a creature of your choosing. Feel free to use/modify/improve upon the function you already made in HW3. It should have at least 4 parameters that enable the calling function to specify arguments for:

1. canvas (positional): a reference to the canvas object.
2. center (positional): a tuple representing the (x, y) coordinate of the centerpoint of the creature.
3. size (keyword): an integer that controls the size of the creature.
4. tag (keyword): a string that gives the creature a unique tag name.

Important: in order for the shapes that constitute your creature to “belong” together, each shape has to be tagged. Please see the sample make_creature function in helpers.py to see how tagging works.

You may also add any additional keyword parameters (i.e., they must be optional, not required) of your choosing to make your creature even more customizable (e.g.: primary_color=’red’, has_sunglasses=True, etc.). Or, feel free to use the random module to create creatures with ‘surprise’ features.

You are also welcome to create additional creature functions (if you want different kinds of creatures to be present in your terrarium / aquarium). That said, please ensure that your main creature function is called make_creature (for our grading pipeline). Any additional creature functions can be named anything that you want and work in any way you want. Up to 2 points will be given for fantastic beasts.

Part 2: Create a make_landscape_object function (7 points)

You have already experimented with stars and bubbles in Homework 4. Here, you will make an object of your own choosing (e.g. a tree, a building, a rock, grass, coral, etc.). To do this, you will create a custom function called make_landscape_object, in helpers.py, that draws a landscape feature of your choosing. It should have at least 3 parameters that enable the calling function to specify arguments for:

1. canvas (positional): a reference to the canvas object.
2. center (positional): a tuple representing the (x, y) coordinate of the centerpoint of the background object.
3. size (keyword): an integer that controls the width of the background object.
4. tag (keyword): a string that gives the landscape object a unique tag name.

You may also add any additional keyword parameters of your choosing to make your landscape object even more customizable (e.g.: color=’red’, texture=’rough’).

You are also welcome to create several different landscape feature functions to make different landscape features. Note that while your main landscape function must be called make_landscape_object, any additional landscape feature functions can be named anything that you want. Up to 2 points will be given for fantastic landscape features.

Part 3. Render your aquarium / terrarium (7 points)

In main.py, you will render your landscape. This involves (a) instantiating some background creatures (using your make_creature function), and (b) creating some landscape features (using your make_landscape_object function).

a. Background creatures

Instantiate at least 5 different “background” creatures in your landscape, located at different positions, and with varying sizes (and colors and features — optional). You may use a loop (and perhaps a random function) to position your background creatures, or you can intentionally place your background creatures in specific places — or some combination of the two.

b. Landscape features

Instantiate at least 5 instances of your landscape feature (in the same manner as you did with your background creatures).

Part 4. Animate your landscape (15 points)

Animate the creatures in your landscape by picking five of the following effects to implement:

NOTE: If you surpass the 15 points (i.e. 5 features), we will award up to 8 points extra credit for pursuing additional enhancements from the list above. So, a sixth feature would be 3 points extra credit, for example.

Part 5. Create a short video (1 point)

Please create a short (like ~15 seconds) video of your terrarium / aquarium in action. To do this:

1. Take a screencast. For Mac users,QuickTime works, and is free. Zoom also enables you to record your screen.
2. Upload it to Google Drive.
3. Share your video so that anyone with link can view.

Reference Materials

Code Samples

I have created some sample code (in demos folder) to help you to understand how to interact with canvas using the keyboard and mouse. Check out the sample code to get some implementation ideas.

TKinter Documentation

You will also want to refer to the tkinter documentation. Here are some useful sites (but feel free to do your own research):

• tkinter events: https://www.python-course.eu/tkinter_events_binds.php
• Canvas: https://anzeljg.github.io/rin2/book2/2405/docs/tkinter/canvas.html
• Other Canvas methods: https://anzeljg.github.io/rin2/book2/2405/docs/tkinter/canvas-methods.html

Policy on sample code and collaboration

YOU MAY….

• Make use of any sample code that I have provided you at any point during the course
• Consult with and incorporate ideas from Internet sources, so long as you are typing the code for yourself (not copying) and understand how every line of it works
• Help each other debug your code and discuss ideas together

YOU MAY NOT…

• Share code — or look at your neighbor’s screen and transcribe their code. We have plagiarism detection software to flag code similarities (e.g. MOSS) — even when whitespace, variable names, and ordering have been changed.
• Blindly copy code from third-party sources and/or incorporate programming techniques that you don’t understand.
• Ask CS majors (or other more experienced people) to write code for you.

What to Turn In

1. Your code as a zip file. This should include all of the files that make your code work.
2. A link to your video (paste it into the text area on Canvas)
3. A (very) short paragraph (bullets fine) indicating which 5 features you implemented for part 4, including any extra credit that you completed. This is critical for helping the TAs look out for the features you implemented. Help us help you get the points you deserve.
