代写Python作业，使用Turtle库绘制图像，完成追逐游戏。
Assignment Objectives
This is an individual assignment. You must submit your own work. This
assignment has three goals:
- Analyzing requirements and developing a solution
- Reviewing python constructs including., if, if-else, if-elif-else, loops, and functions
- Practicing basic python programming
Start the assignment early and avoid procrastination.
Chasing Alice
For this assignment, you develop a turn-based game where you control a blue
turtle, Alex, to chase and catch a red turtle, Alice. Create a canvas (also
known as screen) of size 500 x 500. Alex must appear at the middle of the
canvas. Alice appears at a random location inside the canvas.
In each turn, Alice can move either forward by 20 pixels or she can change her
direction randomly to left or right by 90 degrees. 2/3 of Alice’s movements
should be forward movements and 1/3 should be the random direction changing
left or right.
Alex moves as directed by the player using the keyboard. In each turn, the
buttons w, a, s, and d lead Alex to move forward for 30 pixels, turn left for
45 degrees, back for 30 pixels, and right for 45 degrees, respectively. If
Alex or Alice cross the canvas’s boundaries, they should reappear at a random1
location on the canvas. The game statistic needs to be provided on the screen
as shown in the sample. The game ends if Alex comes within 30 pixels of Alice
in any direction. See figure 2 to get an idea of how the game will look like.
Submission requirements
In order to receive a complete grade no global variable or codes outside
functions should be in your program. Create a main function and control the
program by calling other functions through main. The program starts with
calling main() only. Use constants instead of magic numbers. Follow variable
name conventions all through your code and be consistence. Use white lines to
separate blocks of codes.
Name your program ChasingAlice.py then submit it to the D2L Assignment 2
dropbox by the deadline stated at the top of this document.
Collaboration, Plagiarism, and Cheating
This is an individual assignment and all work that you submit must be your own
work. We encourage you to discuss this assignment with other students in the
course and discourage you from sharing solutions and code with one another.
Sharing solutions and code is a form of plagiarism.
We use automated procedures to detect plagiarism in assignment submissions.
Any student who copies all or part of an assignment that belongs to another
student or other sources will be reported to the Dean. The Dean enforces
penalties, which may include failing the course and expulsion from the faculty
and the university. Please refer to Plagiarism/Cheating/Other Academic
Misconduct in the university calendar or the university website on plagiarism
for more information.
