java - 基于对象文本的 Java 游戏帮助（初学者）

问题描述

所以我必须创建一个Java游戏。我对 Java 很陌生，我整天都在做这个。但我无法弄清楚什么是不正确的。这是我玩游戏的主要课程。我还有一个角色类、一个武器类和一个盔甲类。我现在的问题是我不希望任何玩家的生命值低于0。如果它低于0，则应该将其更改为0，这样就不会再选择那个敌人来对抗了。我想我以某种方式选择了 hp 错误，但我真的不明白如何。任何人都可以帮忙吗？

    This is the code for the Character package:

    ```package Character;
    import java.util.Random;
    import Equipment.*;

    public class Character {
    private Armor armor = new Armor();
    private Weapon weapon = new Weapon();
    private Bag bag = new Bag();

    public int hp, power, defense, mp, level;
    private String name;
    Random rnd=new Random(); 

    public Character(String name) {
        this.name=name;
        Random rnd=new Random();
        this.hp=rnd.nextInt(1000)+1;
        this.power=rnd.nextInt(100)+1;
        this.defense=rnd.nextInt(10)+1;
        this.mp=rnd.nextInt(100)+1;
        this.level=1;
}
    public Character(int hp, int power, String name) {
        this.hp=hp;
        this.power=power;
        this.name=name;
        this.defense=rnd.nextInt(10)+1;
        this.mp=rnd.nextInt(100)+1;
        this.level=1;
}
    public int getHp() {
        return hp;
}
    public void setHp(int hp) {
        this.hp = hp;
}
    public int getPower() {
        return power;
}
    public void setPower(int power) {
        this.power = power;
}
    public int getDefense() {
        return defense;
}
    public void setDefense(int defense) {
        this.defense = defense;
}
    public int getMp() {
        return mp;
}
    public void setMp(int mp) {
        this.mp = mp;
}
    public int getLevel() {
        return level;
}
    public void setLevel(int level) {
        this.level = level;
        if(this.hp==0) {
            this.level = this.level + 1;
        }
    }

    public String getName() {
        return name;
}
    public int damage(int enemy_power) {
        int damage = enemy_power - this.defense;
        if(damage<0){ //avoid healing by damage
            damage=0;
}
        this.hp=this.hp - damage;
        if(this.hp<0) { //avoid negative hp
            this.hp = 0;
}
        return damage;
}

    public Armor getArmor() {
    return armor;
}
    public void setArmor(Armor armor) {
        this.armor = armor;
}
    public Weapon getWeapon() {
        return weapon;
}
    public void setWeapon(Weapon weapon) {
        this.weapon = weapon;
}

    public int hit_point() {
        int total_power = this.power + this.weapon.getPower();
        return total_power;
    }

    public Bag getBag() {
        return bag;
    }
    public void setBag(Bag bag) {
        this.bag = bag;
    }

    public class Bag{
        Weapon weaponArray[] = new Weapon[4];
        Armor armorArray[] = new Armor[4];
        int money = 150;
        public Bag(){
            for(int i=0; i<weaponArray.length; i++) {
                weaponArray[i] = new Weapon();
                armorArray[i] = new Armor();
            }
        }
        public Weapon[] getWeaponArray() {
            return weaponArray;
        }
        public void setWeaponArray(int yourWeaponIndex, Weapon enemyWeapon) {
            this.weaponArray[yourWeaponIndex] = enemyWeapon;
        }
        public Armor[] getArmorArray() {
            return armorArray;
        }
        public void setArmorArray(Armor[] armorArray) {
            this.armorArray = armorArray;
        }
        public int getMoney() {
            return money;
        }
        public void setMoney(int money) {
            this.money = money;
        }

    }
}```

I will also have to figure out a few more things like how to increase the main character's level whenever they kill an enemy. increase the hit_point and decreased the mp if a skill is used (by the way, does anyone know what mp stands for?), and switch out weapons and armor with a dead enemy if theirs is better than mine.

解决方案

这是您的问题：

if(main_ch.hp ==0)

对角色造成伤害后，检查角色的 HP 是否正好为零。如果角色被击中并留下 1 或更多 HP，则战斗可以继续。如果角色被击中HP不足0，战斗仍然可以继续。只有当角色受到一定程度的伤害时，HP 才会精确到 0，战斗才会停止。

幸运的是，您已经描述了修复方法：

如果它低于 0，则应将其更改为 0

这可以像这样完成：

// 将条件从完全零更改为小于或等于零

if(main_ch.hp <= 0) {

    // Added code to reset health

    main_ch.setHp(0);

    System.out.println();
    System.out.println("\t Oh no! You died! Better luck next time. Thanks for playing!");
    System.out.println();
    break;
}

在不相关的注释中，您可能需要重新考虑在此代码中使用循环的方式。您可以通过避免所有标记的 continue 和 break 语句来使您的代码更优雅、更易于阅读，而只需使用嵌套的 while 循环来执行您想要的操作，如下所示：

while(playerWantsToPlay)
{
    // Oh noes! An encounter. Fight or run away bravely?

    while(combatInProgress)
    {
        if(characterIsAlive && targetIsAlive)
        {
            // bash each other in the face
        }
    }
}

continue我想你可以猜到如何根据游戏条件和玩家选择来改变条件来控制游戏的流程，而不用和来回跳转break。
