Create A Graphical Simulation Of An Aerial Dogfight Game

Create A Graphical Simulation Of an aerial dogfight game with enemies and projectiles

In this project, you will create a graphical simulation of an aerial dogfight game. Your program must include a movable friendly fighter aircraft that can defend itself against a squadron of enemy fighters. The user controls the friendly aircraft using keyboard commands to move it up and down and to fire projectiles. The enemy fighters attempt to destroy the friendly aircraft either by crashing into it or by firing their own projectiles. The game continues until all enemies are destroyed, the friendly aircraft is destroyed, or the user chooses to quit.

The user interacts by entering commands via the keyboard to move the friendly fighter vertically and to fire projectiles. Fired projectiles should visually travel across the screen and destroy any target they hit. The number of enemy fighters is specified through a dialog box at the start. Graphics are implemented using the StdDraw package from Princeton University, which provides static methods for drawing shapes and managing display parameters.

Your project must include classes for the aerial objects, specifically an abstract class AerialObject, and subclasses EnemyAircraft, FriendlyAircraft, Projectile. Optionally, you may add moveable ground objects and corresponding classes for extra credit. Additional supporting classes include Pos for coordinate handling, BattleSpace for managing all objects within the game, and AerialDogfight, the main class controlling simulation flow. You must also include StdDraw in your project directory to facilitate graphical output.

The class hierarchy should follow an inheritance structure, with the top-level DogfightObject class containing common attributes and methods. EnemyAircraft and FriendlyAircraft will extend AerialObject, which in turn extends DogfightObject. The FriendlyAircraft is positioned on the left edge, controlled by user input, and can fire projectiles. Enemies appear on the right, moving semi-randomly leftward, potentially firing back at the player’s aircraft.

Projectiles originate from firing aircraft positions, travel in the direction of firing, and destroy target objects upon impact or when leaving the display bounds. The EnemyAircraft can fire projectiles at the FriendlyAircraft, with collision detection managed through coordinate comparisons. The battle simulation is managed by the BattleSpace class, which maintains lists of all objects, handles rendering, and manages interactions. The main execution class, AerialDogfight, initializes the game and runs the simulation loop, updating object states, processing user input, rendering graphics, and checking win/loss conditions.

Your implementation must adhere to best coding practices, including proper use of encapsulation, JavaDoc comments, and style guidelines. The program will be graded on documentation, code style, correct use of inheritance and polymorphism, proper class structure, and fulfillment of specific feature requirements, including user-controlled movement, projectile firing, dynamic enemy behavior, collision detection, and optional scenery and artillery features.

Graphical Simulation of an aerial dogfight game with enemies and projectiles

Introduction

The concept of aerial combat has long fascinated both military strategists and popular culture. Simulations of dogfights not only serve as training tools but also as entertainment, allowing users to experience the thrill of aerial battles in a controlled environment. The development of a computer-based simulation incorporating realistic object models, dynamic movement, and interactive controls presents an engaging challenge that combines graphic programming, object-oriented design, and user interaction management.

Design Philosophy and Class Hierarchies

The core of the simulation hinges on the implementation of a flexible, extendable class architecture. An abstract class AerialObject provides base attributes such as position and velocity, along with abstract methods for drawing and updating states. Derived classes like FriendlyAircraft, EnemyAircraft, and Projectile specialize behaviors suitable to their roles in the game.

The class DogfightObject generalizes common attributes, such as health and collision detection parameters. The Pos class encapsulates coordinate data, simplifying positional calculations and minimizing errors in geometry handling.

The BattleSpace class maintains collections of active objects—enemy aircraft, friendly units, and projectiles—and orchestrates updates to their states with for-each loops. The AerialDogfight class manages the main game loop, processing user input, updating the game state, rendering graphics using StdDraw, and checking win or loss conditions.

Implementation of Key Features

Graphics and Rendering with StdDraw

StdDraw is employed for graphical output. The coordinate system is scaled to encompass the game field, which provides a clear visual representation of objects. Methods like filledCircle are used to draw aircraft and projectiles, with colors indicating target types and states. The display is refreshed each frame, with a controlled frame rate of approximately 60 frames per second to ensure smooth animation.

Aircraft Movement and User Interaction

The FriendlyAircraft’s position along the vertical axis is controlled with the 'U' (up) and 'N' (down) keys, and firing is triggered by the 'F' key. Keyboard input is polled at each iteration of the simulation loop, and the position is updated accordingly. Movement constraints prevent the friendly aircraft from leaving the visible area, enhancing realism.

Enemy Fighter Behavior and Firing Mechanics

Enemy aircraft are instantiated with randomized vertical positions at the right edge. They move leftward, with semi-random vertical adjustments to create unpredictable movement patterns. When reaching a boundary, they change direction, bouncing between top and bottom limits. They can also fire projectiles, which travel in the direction of the enemy’s heading and can destroy any intersected objects. Collisions are detected by comparing the positions of projectiles and objects, with impact resulting in object destruction and score updating.

Projectiles and Collision Detection

Fired projectiles originate from the firing object’s position, travel at a constant speed, and are visually represented using line trails or moving circles. Collision detection compares the positions of projectiles with potential targets—if the distance between a projectile and an object is less than a specified threshold, the object is destroyed and the projectile is removed. Projectile removal also occurs when they travel beyond the game window bounds.

Game State Management and Win/Loss Conditions

The game’s main loop continues until either all enemy aircraft are destroyed or the friendly aircraft is hit or destroyed. When all enemies are eliminated, the player’s score is tallied and displayed via JOptionPane. If the friendly aircraft collides with enemies or is hit by an enemy projectile, the game ends with an appropriate message. The game can also be terminated by a specific user command or window closure.

Features for Extra Credit

• Adding scenery such as rocks, trees, or clouds to create a more immersive battlefield.
• Implementing air artillery positions that fire automatically or controllably, adding strategic depth.
• Creating more sophisticated enemy behaviors, including formation flying and coordinated attacks.
• Allowing full-range movement of the friendly aircraft across the entire battlefield, not just limited to a fixed axis.
• Including enemy projectiles with different firing patterns, such as burst fire or guided missiles.

Conclusion

The simulation encapsulates key principles of game development, drawing heavily on object-oriented programming paradigms—inheritance, polymorphism, and encapsulation. The use of Java’s StdDraw simplifies graphics handling, making the implementation accessible while still providing a visually appealing experience. Proper class design, clear collision detection, and user interaction management ensure a robust simulation capable of extending with additional features.
