我正在尝试检查所选敌人的武器和盔甲,看看它们是否比主角的更好。所以,我想一一检查,如果敌人的武器更好,我想将主角的武器设置为与敌人的武器相同,以便基本上将其放入主角的包中。到目前为止,我所做的一切都是检查一种武器是否更好,并更换所有武器,无论其他武器是否更好。有没有办法可以单独检查每个?

我有四节课。主要的。特点。武器。盔甲。这是我试图切换的主类的一部分:

import java.util.Scanner;

import Character.Character;

public class Main {

public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("> Welcome to The Game Project <");
System.out.println("\n >> Input Main Character Name: ");
String main_name = scanner.nextLine();
System.out.println(">> Input Main Character Power: ");
int main_power=scanner.nextInt();
System.out.println(">> Input Main Character Hp: ");
int main_hp=scanner.nextInt();
System.out.println("----------------------------------------------------");

Character main_ch=new Character (main_hp,main_power,main_name);

这是角色类:

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 static String server_name = "CS172";
public int hp, power, defense, mp, level, skill;
private String name;
Random rnd=new Random();

public Character(String name) {
this.name=name;
Random rnd=new Random();
this.hp=rnd.nextInt(500)+1;
this.power=rnd.nextInt(100)+1;
this.defense=rnd.nextInt(100)+1;
this.mp=rnd.nextInt(50)+1;
this.level=1;
this.skill=5;
}
public Character(int hp, int power, String name) {
this.hp=hp;
this.power=power;
this.name=name;
this.defense=rnd.nextInt(100)+1;
this.mp=rnd.nextInt(50)+1;
this.level=1;

}
public int getHp() {
return hp;
}
public void setHp(int hp) {

}
public int getPower() {

}
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;
}

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 int useSkill() {
this.mp=this.mp-1;
this.skill--;
this.power =this.power + 30;
return hit_point();
}
public int getSkill() {
return skill;
}

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(int yourArmorIndex, Armor enemyArmor) {
this.armorArray[yourArmorIndex] = enemyArmor;
}
// public void setArmorArray(Armor[] armorArray) {
// this.armorArray = armorArray;
// }
public int getMoney() {
return money;
}
public void setMoney(int money) {
this.money = money;
}

}
}

我正在为一个类做这个,我们在类里面和教授一起编写了部分代码。我有一种感觉,我应该以某种方式使用它,但我什至不太明白它在做什么:

public void setWeaponArray(int yourWeaponIndex, Weapon enemyWeapon) {
this.weaponArray[yourWeaponIndex] = enemyWeapon;
}

有人可以向我解释一下吗?

武器类别:

package Equipment;
import java.util.Random;

public class Weapon {
private String name;
private int power;
Random rnd = new Random();
public Weapon() {
this.name="Weapon #" + rnd.nextInt(20);
this.power=rnd.nextInt(50)+1;
}
public Weapon(String name) {
this.name=name;
this.power=rnd.nextInt(50)+1;
}
public int getPower() {
return power;
}
public void setPower(int power) {
this.power = power;
}
public String getName() {
return name;
}

}

装甲等级:

import java.util.Random;

public class Armor {
private String name;
private int defense;
Random rnd = new Random();
public Armor() {
this.name="Armor #"+rnd.nextInt(10);
this.defense=rnd.nextInt(10)+1;
}
public Armor(String name) {
this.name=name;
this.defense=rnd.nextInt(10)+1;
}
public int getDefense() {
return defense;
}
public void setDefense(int defense) {
this.defense = defense;
}
public String getName() {
return name;
}
}

最佳答案

基于您提供的代码

public void setWeaponArray(int yourWeaponIndex, Weapon enemyWeapon) {
this.weaponArray[yourWeaponIndex] = enemyWeapon;
}

此方法使用数组 weaponArray[] 中元素的索引将包的当前武器(这里的对象是包)设置为另一个敌人武器。但是,由于你的数组长度是4,我相信你必须调用它4次才能将4件武器收入囊中。

main_ch.getBag().setWeaponArray(enemies[selected].getBag().getWeaponArray());

在这一行中,您没有指定索引(通常您的方法 setWeapon(int yourWeaponIndex, Weapon nationWeapon) 有 2 个参数

应该是类似这样:

main_ch.getBag().setWeaponArray(i ,enemies[selected].getBag().getWeaponArray());

i是要改变的武器的索引。

示例

main_ch.getBag().setWeaponArray(0 ,enemies[selected].getBag().getWeaponArray() );

如果敌人的武器更好,此行只会更改第一个武器。
