java - 在 if 语句中返回 2 个字符串中的 1 个

问题描述

我正在制作一个小型僵尸生存模拟游戏，并试图添加一些可以增加生存机会的特殊物品。通常，在奔跑中，人类有 10 天的生存时间，并得到一把枪来射击僵尸，如果弹药不足，他们会使用伤害更小但准确性更高的钝器。

在我的个人课程中，有战斗序列方法，我有一个“specialReport”获取方法，我想在“katana”滚动或“ZombieCure”滚动时显示到控制台。

这些项目设置为使用随机数生成器滚动，然后在值为 == 1

第 172-185 行是specialReport()我想在第 37-38 行的驱动程序类中打印出来的方法。

最初我不得不将zombieCureChance生成器和katanaDropProb生成器从第 81 行的 While 循环或 PersonClass 中取出，因为我无法返回它们的值，因为它们在 While 循环的范围内。

但是现在它们在 While 循环之外，我不确定是否会在 DriverClass 的第 28 行的 for 循环中的新一天的每次迭代中重新生成zombieCureChance和的值。katanaDropProb

目前我没有出现任何错误，但输出不是我需要的。

这是 PersonClass 的代码...

这是驱动程序类 ZombieDriver ......

package Zombie;

import java.util.Scanner;



public class ZombieDriver {

    public static void main(String[] args) {

        //WorldClass and PersonClass Object Creation
        WorldClass w1 =new WorldClass(3, WorldClass.getNumZombies(), WorldClass.numZombies, WorldClass.days);
        PersonClass p1 =new PersonClass(PersonClass.humanHealth, PersonClass.humanCount, PersonClass.ammo, PersonClass.availableFood);

        //toString execution
        System.out.println(w1);
        System.out.println(p1);


        Scanner scan = new Scanner( System.in );
        System.out.println("Would you like to play a zombie survival simulator?\n Please type [ y ] or [ n ]");

        String input = scan.nextLine();

        if (input.equals("y")){

            // 10 day simulation
            for (int i=0; i < ZombieUtil.NUM_DAYS; i++) {

                WorldClass.getNumZombies();

                int personCount = PersonClass.fight();

                PersonClass.feedHumans();

                //print out special Items that are found
                String specialReport = PersonClass.specialReport();
                System.out.printf("%n"+specialReport+"%n");

                //daily activity report
                String report = WorldClass.dayReport();
                System.out.printf("%n"+report+"%n");

                //IS THIS AN APPROPRIATE USE OF BREAKING THE LOOP? WITHOUT "BREAK"
                if (personCount <= 0) {
                    i= ZombieUtil.NUM_DAYS;
                }
            }

            if (PersonClass.humanCount > 0 && WorldClass.numZombies <= 0){
                System.out.printf("%n%nAwesome you survived 10 days against a horde of " +
                        "Zombies!!!!!");

            }
            else if (PersonClass.humanCount <= 0 || PersonClass.availableFood <= 0){
                System.out.printf("%n%nIm sorry no one survived the Zombie" +
                        "onslaught :( ");
            }

        }
        else{
            System.out.println("Thank you for playing Zombie Simulator!!");
            //close program
        }


    }
}

我的 Utility 类有这些最终变量，用于调整 Sim 使其可服务......

package Zombie;

public class ZombieUtil {

    public static final int NUM_DAYS=10;
    public static final int START_FOOD_COUNT = 110;
    public static final int START_POEPLE_COUNT =40; //change these where it will be variable to service
    public static final int MIN_ZOMBIES=11;
    public static final int MAX_ZOMBIES=20;
    public static final int ZOMBIECURE_CHANCE=20;
    public static final int KATANA_DROP_PROB=15;
    public static final int KATANAHIT_PROB=1;
    public static final int GUN_HIT_PROB=3;
    public static final int GUN_CRIT_PROB = 2;
    public static final int BLUNT_HIT_PROB =2;
    public static final int BLUNT_CRIT_PROB=10;
    public static final int MISS_DEATH_PROB =2;



}

解决方案

我想到了。我返回的是方法而不是变量specialReport
