简单的Java Pokemon战斗模拟器

Question

我已经编写了一个类来创建和与pokemon战斗，但是我不知道如何调用tester类中的battle方法来测试我编写的类。

我的攻击是编写和测试一个模拟两个口袋妖怪之间的战斗的模拟。每个Pokemon都有一个健康值、一个力量值和一个速度值。健康、强度和速度值作为参数传递给构造函数。这些值最初必须介于1和300之间，并且最初应为非零值。完成游戏的总体想法是，两个精灵将在模拟中“战斗”彼此，精灵轮流攻击。(在每一轮中，速度值最高的那个先走)，攻击型精灵的力量将从“攻击者”的生命值中减去。

public class Pokemon{
  private int health;
  private int strength;
  private int speed;

/**
* Constructs the pokemon
* @Require:
*    health is an integer greater than or equal to 1 but less than or equal to 300
*    strength is and integer greater than or equal to 1 but less than or equal to 300
*    speed is an integer greater than or equal to 1 but less than or equal to 300
*/
public Pokemon(int health, int strength, int speed){
  assert health >= 1;
  assert health <= 300;
  assert strength >= 1;
  assert strength <= 300;
  assert speed >= 1;
  assert speed <= 300;

  this.health = health;
  this.strength = strength;
  this.speed = speed;
}

public void battle(Pokemon pokemon1, Pokemon pokemon2){
  do{
    System.out.println(pokemon1+" begins the fight against "+pokemon2);
    pokemon2.health = pokemon2.health - pokemon1.strength;

    System.out.println(pokemon1 +" does "+ pokemon1.strength +" damage to "+
    pokemon2 +" and "+ pokemon2 +" has "+ pokemon2.health +" left.");

    pokemon1.health = pokemon1.health - pokemon2.strength;

    System.out.println(pokemon2 +" does "+ pokemon2.strength +" damage to "+ 
    pokemon1 +" and "+ pokemon1 +" has "+ pokemon1.health +" left.");

  }while(pokemon1.health >= 1 || pokemon2.health >= 1);
  if(pokemon1.health < 1)
    System.out.println(pokemon1 +" has lost the fight");
  else
    System.out.println(pokemon2 +" has lost the fight");
  }
}

public class PokemonTester{
  private Pokemon charizard;
  private Pokemon blastoise;
  private Pokemon venusaur;

public PokemonTester(){
   charizard = new Pokemon(100,50,50);
   blastoise = new Pokemon(150,25,150);
   venusaur = new Pokemon(300,10,100);
 }

public static void main(String[] args){
  Pokemon.battle(charizard, blastoise); //will not compile
 }
}

我确实意识到我还没有在轮流中实现速度方面，因为我只是试图让它工作。

Answer 1

将static添加到battle函数中，就像在main中一样。

此外，您不能在main中使用charizard和blastoise。不能在静态函数中使用非静态变量。您需要在` `main中创建局部变量

public static void main(String[] args){
    Pokemon charizard = new Pokemon(100,50,50);
    Pokemon blastoise = new Pokemon(150,25,150);
    Pokemon.battle(charizard, blastoise);
}

您还可以创建新的PokemonTester并使用它的变量：

public static void main(String[] args){
    PokemonTester tester=new PokemonTester();
    Pokemon.battle(tester.charizard, tester.blastoise);
}

Answer 2

它对我来说很好。我唯一要说的是代码的错误是你的战斗方法不是静态的。

public static void battle(Pokemon pokemon1, Pokemon pokemon2)

Answer 3

除了使战斗函数成为静态函数外，我还建议进行以下更改。当我运行你的代码时，我得到：

Pokemon@6228a17f begins the fight against Pokemon@c9be777
Pokemon@6228a17f does 50 damage to Pokemon@c9be777 and Pokemon@c9be777 has 100 left.
Pokemon@c9be777 does 25 damage to Pokemon@6228a17f and Pokemon@6228a17f has 75 left.
Pokemon@6228a17f begins the fight against Pokemon@c9be777
Pokemon@6228a17f does 50 damage to Pokemon@c9be777 and Pokemon@c9be777 has 50 left.
Pokemon@c9be777 does 25 damage to Pokemon@6228a17f and Pokemon@6228a17f has 50 left.
Pokemon@6228a17f begins the fight against Pokemon@c9be777
Pokemon@6228a17f does 50 damage to Pokemon@c9be777 and Pokemon@c9be777 has 0 left.
Pokemon@c9be777 does 25 damage to Pokemon@6228a17f and Pokemon@6228a17f has 25 left.
Pokemon@6228a17f begins the fight against Pokemon@c9be777
Pokemon@6228a17f does 50 damage to Pokemon@c9be777 and Pokemon@c9be777 has -50 left.
Pokemon@c9be777 does 25 damage to Pokemon@6228a17f and Pokemon@6228a17f has 0 left.
Pokemon@6228a17f has lost the fight

精灵的名字 @6228a17f和@6228a17f都不是的好名字。要更改这一点，请向构造函数添加一个字符串类型的name字段，并相应地使用它。战斗模拟显然是错误的，因为(a)战斗“开始”每个回合(b)战斗不会停止后，口袋妖怪的生命已经下降到0或更低。为了解决这个问题，我建议使用一个入口控制的while循环，而不是do-while，并在第一个转弯后插入一个break语句。应用这些更改，您的程序将如下所示：Pokemon:

public class Pokemon{
    private int health;
    private int strength;
    private int speed;
    private String name;
    public Pokemon(String name, int health, int strength, int speed){
        assert health >= 1;
        assert health <= 300;
        assert strength >= 1;
        assert strength <= 300;
        assert speed >= 1;
        assert speed <= 300;
        this.health = health;
        this.strength = strength;
        this.speed = speed;
        this.name = name;
    }

    public static void battle(Pokemon pokemon1, Pokemon pokemon2)
    {
        System.out.println(pokemon1.name+" begins the fight against "+pokemon2.name);
        while
        (pokemon1.health >= 1 || pokemon2.health >= 1)
        {

            pokemon2.health = pokemon2.health - pokemon1.strength;

            System.out.println(pokemon1.name +" does "+ pokemon1.strength +" damage to "+
                pokemon2.name +" and "+ pokemon2.name +" has "+ pokemon2.health +" health left.");

            if
            (pokemon2.health <= 0)
            break;

            pokemon1.health = pokemon1.health - pokemon2.strength;

            System.out.println(pokemon2.name +" does "+ pokemon2.strength +" damage to "+ 
                pokemon1.name +" and "+ pokemon1.name +" has "+ pokemon1.health +" health left.");

        }

        if
        (pokemon1.health < 1)
            System.out.println(pokemon1.name +" has lost the fight");
        else
            System.out.println(pokemon2.name +" has lost the fight");
    }
}
