Towers Assignment python 辅导、辅导python程序

1. Introduction

This assignment provides you the opportunity to apply concepts taught throughout the

course to extend the functionality of a basic tower defence game.

The assignment will focus on the concept of Graphical User Interfaces (GUIs) and objectoriented

programming. You will be required to extend the functionality of the base game to

achieve marks.

Students are encouraged to review some tower defence games, to better understand how

this type of game is played and for inspiration on advanced features.

Because this assignment deals with multiple files, while not required, you may wish to

investigate a more sophisticated IDE. One option is PyCharm, which is free for students.

In the first week after this assignment is released, some updates are expected to be made to

improve the quality of the support code. These will be non-breaking changes to the

assignment code and will not be to the file. You can incorporate the changes into

your assignment by overwriting the modified files in the project.

1.1. Game Play

Shortly after this assignment's release, a link to a video overview will be added here.

2. Overview

2.1. Getting Started

The archive contains all the necessary files to start this assignment. A

significant amount of support code has been supplied to make it possible to begin with a

simple application that is almost working.

a3.py

a3_files.zip

The main assignment file is , which contains an incomplete implementation of

, the top-level GUI application class. The other files are support code which

must not be edited. Initially, you do not need to understand much of this code, but as you

progress through the tasks, you will need to understand more of this code. You should add

code to and modify to implement the necessary functionality.

You are permitted to create additional files to simplify the separation of tasks (i.e. task1.py,

task2.py, etc.), although this is not required. If you do this, must be the entry point to

your application. One way to achieve this is to move to a separate file, such

as . Regardless of how you structure your files, the code must all be able to

be demonstrated by running .

3. Assignment Tasks

3.1. Task Overview

This assignment is broken down into three main tasks:

1. The first task involves adding lines of code to clearly marked sections within the main

assignment file

2. The second task involves extending the design to add more interesting functionality to

the game

3. And the third task involves adding sophisticated functionality to further improve the

gameplay experience

For post-graduate students only, there is an extra task that involves doing independent

research.

In general, as the tasks progress, they are less clearly prescribed and increase in difficulty.

3.2. Task Breakdown

CSSE1001 students will be marked out of 20 & CSSE7030 students will be marked out of

26 based on the following breakdown. Tasks may be attempted in any order, but it is

recommended to follow this breakdown, top-down, completing as much as possible of each

task before moving on to the next.

3.3. Mark Breakdown

For each task, marks will scaled according to the following breakdown.

Description Marks

Code Quality

Code is readable. Appropriate and meaningful identifier names

have been used. Simple and clear code structure. Repeated code

has been avoided.

15%

Code has been simplified where appropriate and is not overly

convoluted.

10%

Documented clearly and concisely, without excessive or

extraneous comments.

15%

Functionality

Components are functional, without major bugs or unhandled

exceptions.

Assessed through user testing/playing, not automated testing.

60%

4. Task 1 – Basic GUI

Basic GUI Example

There are a significant number of comments in intended to help you complete this

task.

4.1. App Class

Write a function that launches the GUI. Call this function inside

an block.

Modify so that the title of the window is set to something appropriate (i.e.

Towers).

4.2. Tower Placement

Allow the user to place a tower by clicking a grid cell with the mouse. While their mouse is

being moved over the , show a preview of the tower and its range in the current

cell as well as the new path the enemies would take if a tower were placed there. When the

mouse leaves the , hide the preview.

If placing a tower in the current grid cell would make it impossible for the enemies to move

through the grid, or there is already a tower there, the preview should indicate that this

would not be a legal placement by showing an X shape instead of the tower.

4.3. StatusBar Class

Define a class named , which inherits from . This class is used to

display information to the user about their status in the game. The ' s widgets
