Java - 访问对象

Question

我有一个关于对象的问题。我开发了某种基本的角色扮演游戏。在这个游戏中我有一个角色(假设这个角色对象是英雄)。英雄有主手装备，防弹衣等。这个英雄想用主手的武器攻击，假设他有一把长剑。

关于我的武器类的一个词——这个类中的对象有“攻击”方法。此方法将攻击者和目标作为参数，因此(此处为武器对象).attack(hero, hero2) 使用武器对象攻击 hero2 进行英雄攻击。

我的问题如下 - 当代码知道“hero”是第一个调用攻击方法的对象时，我能否以某种方式避免使用 attack(hero, hero2)？

这是攻击命令:

hero.getEquipment().getPrimaryHand().attack(hero, hero2);

“这里的一些代码”是否可以替换为可以替换攻击方法中的“英雄”的东西？

hero.getEquipment().getPrimaryHand().attack(some code here, hero2);

编辑:添加 MeleeWeapon 类(武器的子类):

public class  MeleeWeapon extends Weapon {

boolean throwable;

MeleeWeapon(String name,String reqTraining, boolean oneHaned, int n, int dice, int attackBonus, int damageBonus,double weight, long cost, boolean throwable) {
    super(name, reqTraining, weight, cost, oneHaned, n, dice, attackBonus, damageBonus);
    this.throwable = throwable;
}

static ArrayList<MeleeWeapon> meleeWeaponList = new ArrayList<MeleeWeapon>();

static
{
    meleeWeaponList.add(new MeleeWeapon("Long Sword","Martial", true, 1, 8, 0, 0,8, 10, false));
    meleeWeaponList.add(new MeleeWeapon("Short Sword", "Martial", true, 1, 6, 0, 0,5, 5, false));
    meleeWeaponList.add(new MeleeWeapon("Dagger","Basic", true, 1, 4, 0, 0,2, 3, true));
    meleeWeaponList.add(new MeleeWeapon("Quarter-staff", "Basic", false,  1, 4, 0, 0,3, 2, false));
    meleeWeaponList.add(new MeleeWeapon("Shield", "Shield", false, 1, 4, 0, 0,8, 8, false));

}


public void attack(Character attacker, Character defender){

    int attackRoll = DiceRoller.roll(20) + attacker.getBaseAttackBonus() + attacker.getModifier(attacker.getStrength()) + getAttackBonus() ;
    System.out.println(attacker.getName() + " attack Roll: " + attackRoll + "AC: " + defender.getArmorClass());

    if (attackRoll >= defender.getArmorClass()){
        System.out.println("Defender: " + defender.getName() + " had " + defender.getCurrentHp());
        int damage = DiceRoller.roll(getN(), getDice()) + attacker.getModifier(attacker.getStrength()) + getDamageBonus() ;
        System.out.println("Damage : " + damage);
        defender.setCurrentHp(attacker.getCurrentHp() - damage);
        System.out.println("Defender: " + defender.getName() + " has " + defender.getCurrentHp());
    } else {
        System.out.println("Missed Attack");
    }

}

Answer 1

你可以在你的 Character 类中有一个攻击方法来包装你的其他 attack 方法:

public void attack (Character other) {
    getEquipment().getPrimaryHand().attack (this, other);
}

你可以简单地调用它:

hero.attack (otherHero);
