用java写一个级简版的dota =.= （轻喷）
设计类图：

Unit.class:

package com.dota;

public abstract class Unit {

    public String name;
    private int HP = 0;
    private int ATK = 1;
    private int armor = 0;
    private boolean isLive = true;
    
    public void getHurt(int harm){
        this.HP -= (harm-armor);
        if(HP <= 0)
            isLive = false;
    }
    
    public boolean isLive() {
        return isLive;
    }

    public void setLive(boolean isLive) {

    }

    abstract void attack(Unit target);
    
    abstract void beAttack(Unit attacker);

    public int getHP() {
        return HP;
    }

    public void setHP(int hP) {

        this.armor = armor;
    }

    public String getName() {
        return name;
    }
    
}

Tower.class:

package com.dota;

        System.out.println("开启塔防");
    }

    @Override
    void beAttack(Unit attacker) {
        
    }

}

Creature.class:

package com.dota;

public abstract class Creature extends Unit {

    private int MP = 0;
    private int speed = 300;
    
    public int getMP() {
        return MP;
    }
    public void setMP(int mP) {
        MP = mP;
    }
    public int getSpeed() {
        return speed;
    }
    public void setSpeed(int speed) {
        this.speed = speed;
    }
    
    public void move(Point p){
        System.out.println("移动到"+p.toString());
    }
}

Hero.class

package com.dota;

import java.util.Random;

public class Hero extends Creature {

    private Skills[] skills = new Skills[4];
    
    public Skills[] getSkills() {
        return skills;

    }
    
    
    void attack(Unit target) {
        int temp = new Random().nextInt(100);
        if(temp < 30){
            System.out.println("⊙＿⊙ !!,"+ this.name +"打出了一下 Mis");
        }else{
            target.beAttack(this);
        }
    }

    @Override

        }else{
            System.out.println(attacker.name +"正在攻击"+ getName() +",造成了"+ attacker.getATK() +"点伤害");
            getHurt(this.getATK());
        }
    }

}

Point.class

package com.dota;

public class Point {

    public int x, y;
    
    public String toString(){
        return "坐标("+ x +","+ y +")"; 
    }

        double d = Math.pow((x - p.x), 2) + Math.pow((y - p.y), 2);
        return Math.sqrt(d);
    }
}

Skills.class

package com.dota;

import java.util.Timer;
import java.util.TimerTask;

public class Skills{

    public String skillName;
    public int costMP = 0, spellTime = 0, harm = 0, CD = 0;
    
    
    public Skills(String skillName, int costMP, int spellTime, int harm, int cD) {
        super();
        this.skillName = skillName;
        this.costMP = costMP;
        this.spellTime = spellTime;
        this.harm = harm;
        CD = cD;
    }

    public void use(Hero h){
//      new Timer().schedule(new TimerTask() {
//          public void run() {
//              System.out.println("消耗了"+ costMP +"点魔法值,"+"对"+ h.name +"使用了"+ skillName +",造成了"+ harm +"点伤害");
//          }
//      }, spellTime * 1000);
        System.out.println("消耗了"+ costMP +"点魔法值,"+"对"+ h.name +"使用了"+ skillName +",造成了"+ harm +"点伤害");
        h.getHurt(harm);
    }
    
}

写在后面：

当然实现一个dota是不可能的，主要是为了巩固一下java面向对象的知识，一些概念的深化理解，自己动手写确实是最有效的途径
