#16 定義兩個類別， 用到繼承， 類別裡包含屬性和方法，在方法裡有使用到屬性，然後用類別生出物件 存取物件的屬性和呼叫物件的方法。

用寶可夢Game Freak親兒子小火龍當作實例

// 定義寶可夢類別
class Pokemon {
    var name = String()
    var hp = Double()
    var attack = Double()
    var defense = Double()
    var specialAttack = Double()
    var specialDefense = Double()
    var speed = Double()
    var terastal = String()
    var type = String()
    var type2 = String()
    
    //印出寶可夢基本資料
    func baseStats(){
        print("\(name) 屬性: \(type)")
        if (type2 != ""){
            print("\(name) 第二屬性: \(type2)")
        }
        print("\(name) 太晶化屬性: \(terastal)")
        print("\(name) 血量: \(hp)")
        print("\(name) 攻擊: \(attack)")
        print("\(name) 防禦: \(defense)")
        print("\(name) 特攻: \(specialAttack)")
        print("\(name) 特防: \(specialDefense)")
        print("\(name) 速度: \(speed)")
    }
    
    //得到噴射火焰技能
    func skillFlamethrower(){
        var power = 90.0
        if ((type == "火" || type2 == "火") && terastal == "火") {
            power = power * 2
        } else if(type == "火" || type2 == "火"){
            power = power * 1.5
        } else if(terastal == "火"){
            power = power * 1.5
        }
        print("\(name) 使出了 噴射火焰 招式威力:\(power)")
    }
    
}

var charmander = Pokemon()
charmander.name = "小火龍"
charmander.type = "火"
charmander.terastal = "火"
charmander.hp = 39
charmander.attack = 52
charmander.defense = 43
charmander.specialAttack = 60
charmander.specialDefense = 50
charmander.speed = 65
charmander.baseStats()
charmander.skillFlamethrower()

捕捉到的小火龍

繼承寶可夢類別的極巨化類別

//極巨化繼承寶可夢類別
class Dynamax: Pokemon {
    var dynamax = "超極巨化"
    
    //獲得超強極巨化招式
    func skillGMaxWildfire(){
        var power = 130.0
        if(type == "火" || type2 == "火"){
            power = power * 1.5
        }
        print("\(name)使用極巨腕帶 極巨化成為 \(dynamax+name)")
        print("\(dynamax+name) 使出了 超極巨地獄滅焰 招式威力:\(power)")
    }
}

var charizard = Dynamax()
charizard.name = "噴火龍"
charizard.type = "火"
charizard.type2 = "飛行"
charizard.terastal = "火"
charizard.hp = 78
charizard.attack = 84
charizard.defense = 78
charizard.specialAttack = 109
charizard.specialDefense = 85
charizard.speed = 100
charizard.baseStats()
charizard.skillFlamethrower()
charizard.skillGMaxWildfire()

極巨化後的噴火龍
