This is the fifth of a series of tasks in which you will develop a small program. These tasks are designed to help you explore the concepts being covered, and to practice your programming skills.
The material in Course 3, Week 2 will help you with this task.
In this task you will design and implement some new features for the RobotDodge game.
Submit the following files to OnTrack.
A short design report, highlighting the changes you made
The program’s code (Bullet.cs, Program.cs, Player.cs, Robot.cs, and RobotDodge.cs) A screenshot of your program running
You want to focus on communicating your design changes, as well as iteratively adding these new features to your program. You will need to use what you have learnt from the previous iterations of this task.
The RobotDodge game has been progressing well, now the client has seen what we have produced they want to make some new additions. You have been tasked with designing and implementing these changes.
The new features are:
The player should have lives that are they collide with a Robot.
The lives should be shown on the screen. Something like small heart pictures, drawn on the edge of the screen.
Start with 5 lives
Quit the game with the player has no lives left
The Player should have a score, that increases as time passes.
Show the score somewhere on the screen.
The player should get 1 point for every second that passes. So the longer they survive the
higher their score.
The Player should be able to shoot a bullet.
Clicking the mouse will shoot a bullet from the player toward the mouse.
The bullet should be able to destroy one robot, then disappear itself.
The bullet can be drawn as a circle. (feel free to pick any color)
Here is some guidance on how to approach this task, this outlines the expectations for the design document and the code:
- Create a UML Class Diagram for the solution. You can start by copying the existing design, then add in the new responsibilities you want.
We recommend that you use LucidChart for this. You can get a pro account with your Deakin email address.
- Think carefully about where to allocate the different responsibilities.
- SplashKit includes a code that works with a Timer:
class that you can use to keep track of time. Here is some example
- Review how the Robot targeted the Player for ideas on the bullet.
- You can test circle collision using .
The design document needs communicate how bullets have been added to the solution. You will need to provide the overall UML Class Diagram along with accompanying descriptive text. You can also include other sequence diagrams to aid your communication. For the report you want to focus on the following:
The details of how the bullet works.
This is the most complex part of the design. Focus on the following:
How are bullets modelled How do bullets move
How do bullets destroy the robots?
Write the report for a knowledgable developer. Write it as if you were describing this to the unit’s teaching staff. Remember to keep in mind what you are aiming to communicate: which in this case is how you changed the design to incorporate bullets. So avoid explaining concepts that the reader will already understand, and focus on communicating your solution.
It would be a great idea to share your design with the teaching staff before you start coding it. Email it
to your tutor and ask for their feedback, they should get back to you quickly with some ideas. Once you have the green light, go ahead and code up your new additions!
When you are finished the design document, and the code, submit your work to OnTrack for feedback.
