java - Java 游戏逻辑的独立线程

Question

当我制作简单的单线程游戏时，我以与日益著名的 Space Invaders tutorial 大致相同的方式实现游戏逻辑。如下图所示:

public static void main(String[] args) { //This is the COMPLETE main method
    Game game = new Game(); // Creates a new game.
    game.gameLogic(); // Starts running game logic.
}

现在我想尝试在单独的线程上运行我的逻辑，但我遇到了问题。我的游戏逻辑位于一个单独的类文件中，如下所示:

public class AddLogic implements Runnable {

    public void logic(){
        //game logic goes here and repaint() is called at end
    }

    public void paintComponent(Graphics g){
        //paints stuff
    }

    public void run(){
        game.logic();  //I know this isn't right, but I cannot figure out what to put here.  Since run() must contain no arguments I don't know how to pass the instance of my game to it neatly.
    }

}

...我的主要方法如下所示:

public static void main(String[] args) { //This is the COMPLETE main method
    Game game = new Game(); // Creates a new game.
    Thread logic = new Thread(new AddLogic(), "logic");  //I don't think this is right either
    logic.start();

}

如何在游戏实例上正确调用logic()方法？

Answer 1

您可以使用构造函数或 setter 来传递游戏实例，如

public GameThread extends Thread {
  private Game game;

  GameThread(Game game) {
    this.game = game;
  }

  public void run() {
    game.logic();
  }
}

public static void main(String[] args) {
  GameThread thread = new GameThread(new Game());
  thread.start();
}
