Java实现RPG游戏 – 源码巴士

一．实验目的

掌握面向对象程序设计的方法。
明确类与对象的概念，掌握面向对象设计七大原则；
掌握常见的设计模式以及类图的描述。

二、UML类图
在这里插入图片描述
三、实验要求
1.功能描述几乎所有的RPG游戏（一种源自《龙与地下城》的游戏类型）在进入游戏时都会让用户自己来创建自己喜欢的角色。
本次上机要求编写一个简化的创建游戏角色的程序。

2.游戏角色应有的属性本题目要求的游戏角色应有以下属性：名字、性别、种族、职业、力量、敏捷、体力、智力、智慧、生命值和魔法值。
名字：不超过50个字符。
性别：可以选择男性和女性。
种族：一共可选五个种族，人类、精灵、兽人、矮人和元素。
职业：可选六种职业，狂战士、圣骑士、刺客、猎手、祭司和巫师。其余属性均为整数。
本题目要求首先用户输入角色姓名，然后由用户选择角色性别，然后由用户选择种族，然后选择职业，然后自动分配力量、敏捷、体力、智力和智慧属性，并计算生命值和魔法值。
生命值=体力*20。
魔法值=（智力+智慧）*10。

3.职业限制很多职业会限制某些种族选择，例如兽人不能就职圣骑士等等，种族和职业的限制表如下：

4.初始属性
本题目要求力量、敏捷、体力、智力和智慧要求是随机值（利用随机数函数来取得随机数），但是五项属性的总和应该是100，并且应该和职业相关。例如狂战士的体力和力量就要比较高，而巫师需要较高的智力，而祭司则需要较高的智慧。各职业初始属性的大致比例应遵从下表：

四、程序实现
姓名和性别


public class Role {
    private String name;
    private int gender;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getGender() {
        return gender;
    }

    public void setGender(int gender) {
        this.gender = gender;
    }

    public int Setting() {
        System.out.println("请输入角色姓名：");
        Scanner sc = new Scanner(System.in);
        this.name = sc.next();
        while (true) {
            System.out.println("输入角色性别：（0.男    1.女）");
            this.gender = sc.nextInt();
            if (gender == 0 || gender == 1) {
                break;
            } else {
                System.out.println("请选择0或1来确认性别");
            }
        }
        return gender;
    }

    public void output(){
        System.out.println("------------------------");
        System.out.println("姓名\t\t\t"+this.name);
        System.out.println("------------------------");
        if(this.gender==0){
            System.out.println("性别\t\t\t"+"男性");
        }else{
            System.out.println("性别\t\t\t"+"女性");
        }
    }
}
