Spring 2006 Homework 3

Due: Monday the 27th at 7PM

Basic requirements

You are going to make an animation that is at least 50 frames long. Write a function called animation that takes in a directory as a string. When run, this function will create at least 50 frames of your animation (as JPEG files) in the directory you passed in. These frames should be named something like frame001.jpg, frame002.jpg, frame003.jpg, etc. Each frame will be the same size and no more than 500 pixels wide and 300 pixels high. You should save this in a file named hw3.py. You are also required to use more than one function.

Something Walking

During this animation, you must have a walking animation of some sort. You will accomplish this by using sequence of predrawn images of a walking figure. Here are a few examples that you can use, but you are encouraged to find/make/photograph your own.

Collision/Interaction

Your animation must also interact with another image that you will create using one of the many drawing functions within JES. These include

rectangles
circles
text

For example, your walking character could run into a wall you create with a rectangle and say "ouch" using the addText function. Alternatively, your character could kick around a ball created with the addOval function. Be creative.

In addition to walking...

In addition to walking, your character must also do something else for part of the animation. For example, you could make John Cleese walk to the center of the background during the first 40 frames, and then he could stop and say "And now for something completely different" for the last 10 frames.

The images you use

Please turn in all the images that you use in your animation to webwork along with your code. If you do not turn in your images, then your homework becomes very difficult to grade. Inside your code, use getMediaPath to access your images. When your TA grades your homework, they will put all your images into a random folder and set the media path to that folder and expect your code to run smoothly.

Summary/Checkoff list
You will be graded on the following:

Your function name and file are correct
Your function takes in a directory
Your function outputs frames to that directory
Your function uses images from the media path
You use at least two functions
Your frames have an animation of a figure walking
Your frames have some other drawn image on it
Your walking figure and drawn image interact somehow
Your walking figure does something else for some amount of time

Hints

Use mod with the frame number to figure out which picture to use for your walking animation
For your extra function make a generic copy function that can copy a picture onto a canvas at an arbitrary set of coordinates you pass into it
To make your animated character do something different for part of the movie, use if statements that make decisions based on the frame number.

Above and Beyond

5 points of extra creidt - Have two different walking characters move in opposite directions. (although no moon walking allowed)
2 points of extra credit - You may notice that some of the example pictures have a hideous green background. This is ideal for using chromakey. If you use chromakey while copying your images, then you will get an additional 2 points.
Eternal fame - Lastly, there will be a competition for the best movies. The top 5 movies in each section (judged by a panel of TAs) will be shown in class. If you wish to be considered, include the line #please consider me for the movie contest at the top of your code by your collaboration statement. Sorry, we can't offer you extra credit for this part, but Blake says he'll buy you a cookie if you win.
