CSc 101: Car Drive

In this assignment, you will write a processing program that generates a very simple animation of a car driving. Below is an example of what the finished product should resemble:

There are several things to notice about this animation, all of which you should mimic:

• There are several items on the screen that do not move: the sky, the ground, the road, and the car.
• There is one tree that moves across the screen, and five birds. Even though the car is not moving, when the other shapes move, it create the effect that car is actually progressing forwards.
• The tree and birds begin off-screen and move across once from left-to-right.
• The birds move at a slightly faster rate than the tree does.
• The tree and birds only need to “cross the screen” once.

You should use lines or custom shapes for the birds. The car must have at least a body, wheels, tires, and a window. If you want, you can make the car, birds, or tree much more detailed and intricate.

Your code should have a global variable to control the car's speed. This means that when you change such a variable, the car appears to move faster or slower. You should clearly state the variable name in the header and add an in-line comment in the variable declaration explaining how to use the variable.

Name your file car_drive.pde.

Programming strategy

You should start by getting the static (non-moving) parts of the drawing on the screen. These are the sky, earth, road, and car. Once you have the static parts finished, work on the tree movement. The tree is a little easier than the birds since you don’t need to repeat anything.

Lastly, do the birds. There must be 5 birds and they must be “repeated” using a for-loop.

Comments

Each program file should have a header comment at the top that has the following format:

/*
 * Author: Student Name.
 * Description:
 *    A short description of what this program does!
 * Variable name that controls the speed: Your variable name.
 */    

All of your programming should be well-formatted and easy for the graders to read and comprehend. To help with readability, separate the code that creates the main shapes in your program with a blank line and include a comment that describes the shape(s) being created. For example,

// the sky
rect(...);

Submission and grading

It is due on 10/4/2024 at 11:00pm.

Turn in both files described in the Assignment 4 spec (2 total) to Gradescope before the due date. (Note: You must select the files for both part 1 and part 2 and drag them into the Gradescope upload box.) Make sure to name the files exactly as the Part 1 and Part 2 documents specify. In general, make sure to follow these instructions precisely.
