When you code your project and you use object-oriented programming concepts, how would you split up your classes?
I'm trying to code a simple game demo and I am looking to use Java to make a GUI. So far, I am having trouble splitting up classes because I really have no organisational
skills whatsoever!
I am currently making a shooter where I control a crosshair on the screen via mouse and shoot flying disembodied heads. I understand how to program to register a shot, but what I don't know about is how I should split it up. I understand, though, that there will be more than one time at which I have to split up the work into different classes.
My question, if not made clearly through this thread, is, how to organise?
Well, in my opinion, the Readability and maintainability of your code can be significantly increased by structuring it in an object-oriented manner. In the context of a simple game like your shooter, you can consider organizing your classes based on different components and responsibilities.
Here is the simple code for your kind reference.
// Game.java
public class Game {
public static void main(String[] args) {
GameWindow gameWindow = new GameWindow();
Player player = new Player();
Enemy enemy = new Enemy();
Bullet bullet = new Bullet();
CollisionManager collisionManager = new CollisionManager();
// Game loop
while (true) {
player.update();
enemy.update();
bullet.update();
collisionManager.checkCollisions(player, enemy, bullet);
gameWindow.render(player, enemy, bullet);
}
}
}
// Player.java
public class Player {
private int x, y; // player position
public void update() {
// handle player input and update position
}
public void shoot() {
// logic for shooting
}
}
// Enemy.java
public class Enemy {
private int x, y; // enemy position
public void update() {
// logic for enemy movement and behavior
}
}
// Bullet.java
public class Bullet {
private int x, y; // bullet position
public void update() {
// logic for bullet movement
}
}
// GameWindow.java
public class GameWindow {
public void render(Player player, Enemy enemy, Bullet bullet) {
// rendering logic
}
}
// CollisionManager.java
public class CollisionManager {
public void checkCollisions(Player player, Enemy enemy, Bullet bullet) {
// collision detection logic
}
}
// Game.java
public class Game {
public static void main(String[] args) {
GameWindow gameWindow = new GameWindow();
Player player = new Player();
Enemy enemy = new Enemy();
Bullet bullet = new Bullet();
CollisionManager collisionManager = new CollisionManager();
// Game loop
while (true) {
player.update();
enemy.update();
bullet.update();
collisionManager.checkCollisions(player, enemy, bullet);
gameWindow.render(player, enemy, bullet);
}
}
}
// Player.java
public class Player {
private int x, y; // player position
public void update() {
// handle player input and update position
}
public void shoot() {
// logic for shooting
}
}
// Enemy.java
public class Enemy {
private int x, y; // enemy position
public void update() {
// logic for enemy movement and behavior
}
}
// Bullet.java
public class Bullet {
private int x, y; // bullet position
public void update() {
// logic for bullet movement
}
}
// GameWindow.java
public class GameWindow {
public void render(Player player, Enemy enemy, Bullet bullet) {
// rendering logic
}
}
// CollisionManager.java
public class CollisionManager {
public void checkCollisions(Player player, Enemy enemy, Bullet bullet) {
// collision detection logic
}
}
Thanks
