COMP2011J - Object Oriented Programming Individual Assignment: Defender

Assignment Details

Due date: 6 th of December 2024

Language: Solution must be completed in Java

Game Description Defender is a classic arcade game where the player flies a spaceship destroying alien invaders over a planet.

Defender is a side-view, horizontally scrolling shooter set on the surface of an unnamed planet. The playercontrols a spaceship flying either to the left or right. The player can control the elevation of the ship as well asfire weapons and make a hyperspace jump.The object is to destroy all alien invaders, while protecting astronauts on the landscape from abduction.Landers pick up humans and attempt to carry them to the top of the screen at which point they turn intofast-moving mutants. A captured human can be freed by shootingthe lander, then catching the human beforeit falls to its death, and dropping it off on the ground.Defeating the aliens allows the player to progress to the next level. Failing to protect the astronauts resultsin the level being lost (and started again if you have remaining lives). A ship is lost if it is hit by an enemy orits projectiles, or if a hyperspace jump goes wrong (as they randomly do). After exhausting all ships, the gameends.

1Movement

The players ship can move up and down on the screen. When it does the screen does not move. The playersship can not go any lower than the bottom of the screen or any higher than the top of the screen.As the player moves left and right the screen should move to show more of the level. The player ship shouldbe kept in the middle half ofthe screen. That is when the player is in this area, the screen should not move.However, if the player is going to move outside of this area, then the view of the level should be changed so theplayer remains in the middle half of the screen.For theplayers ship moving left and right the important element of movement is momentum. The player’sship should continue travelling in the same direction at the same speed unless some acceleration is applied. Sowhen the players ship begins moving and no more thrust is applied, it will continue in the same direction and

at the same speed forever unless the ship crashes into an alien. The direction that the ship travels is based onthe direction that the ship was facing when the thrust wasapplied. If no thrust is being applied, then the shipn face in any direction while it keeps moving in the direction of the original thrust.

Enemies

There are two types of enemies in the game, Landers and Mutants.Landers will fire at the player’s ship, but their primary goal is to grab on of the humans from the surfaceand carry them to the top of the screen. One the lander reaches the top of the screen carrying a human theywill become a mutant. If a lander is destroyed whilethey arecarrying a human, the human is dropped andmust be caught by the player. If the player does not catch the human, they will die when they hit the ground.If the player catches a human, they can place them back on the ground by dropping down to that level.Mutants are much faster than landers. Instead of attempting to pickup humans, mutants only purpose isto kill the player. They will chase after and fire at the player.

Points/Scoring

Points are awarded for destroying the asteroids based on the following calculations:

  • Lander destroyed 150 points each
  • Mutant destroyed 300 points each
  • Human captured and mutated -150 points each
  • Human saved 500 points each

Levels

The number of humans and enemy landers is based on the level. As levels increase there should be more landersand less humans on the level.A level is not completed until all of the enemy ships have been destroyed. This may require the player tosearch across the landscape to find the remaining enemies.

Example

To get an example of the how the defender game plays, go to the https://www.free80sarcade.com/defender.php and play the game there. This version of the game has alarger number of enemy types and is quite difficult.he version I am requiring you to create only requirestwtypes of enemies and can be made easier (by makinghe enemies move more slowly).

Assessment

This section gives a breakdown of the approximate marking criteria for the assignment. The final markingscheme may vary slightly but will be relatively similar. Your submission should contain the following filesA zip 代写COMP2011J - Object Oriented Programming file containing the entire project code and any other files required for the code to be executed(exported from IntelliJ IDEA or Eclipse)2• A report explaining what you have achieved for each of the criteria in the marking scheme (estimate fail,pass or excellent) based on the template provided

  • A short video (less than 3 min) showing a screen recording of the game with your explanation voiced overitEach file should be named only with your UCD student number and the correct file extension (e.g. 1234567.zip,1234567.pdf, and 1234567.mp4).

Zip File

This must contain all of the code required to execute the project. If I am unable to execute your code, it willreduce your grade. If there are any requirements to setup andexecute your code you should include these inIntellij IDEA IDE and export the entire project to azip file for submission.

Assignment Report This document should be in PDF format and contain your name and student number as well as a table explainingwhat you estimate of how your project will be gradedagainst the marking criteria in the next section. For eachof the criteria mark an X under Fail, Pass, or Excellent and hat you have added that you believe should be worth extra credit.

Marking Scheme

The marking scheme shown in table 1 is subject to change. This means that it may be changed at any timewithout notice if I feel some parts were too easy or too hard and additional criteria may be added. The finalgrade from this section will be based on a weighted sum of the individual parts. The weights for each part willbe based on the difficulty and importance. Forexample,design and cohesion is very important and will likelybe weighted much higher than any other component.The each can be used as a guide to the amount of work expected for the different parts ofthe assignment.You should also note that it is required that your project is programmed using one of the two libraries available on moodle (https://csmoodle.ucd.ie/moodle/mod/folder/view.php?id=74336 or https://csmoodle.ucd.ie/moodle/mod/folder/view.php?id=74337). If you do not use one of these libraries, then you will get

0 for your assignment grade.

Additional Criteria

In addition to the above, your submission will also be considered under some more criteria. These however areonly used to reduce your grade if you have performed poorly and will otherwise have no effect.Naming of variables, methods, class, interfaces, enumerated types or anything else in your code

  • Following naming conventions for the above
  • Code formatting and commenting1
  • Correct formatting of submitted files (e.g you will lose points for submitting a doc file instead of a pdf,mkv instead of mp4, or rar instead of zip)
  • Incorrect naming of any submitted files
  • Not including name and student number in report (or including an incorrect student number)
