[iOS study] 撲克牌poker二十一點遊戲開發

要做撲克遊戲先要把52張牌做出來：

這裡想用array跟迴圈來做，並把圖片名稱統一改為花色加數字

自創型別

import Foundation
struct PokerCards {
var Level:Int
var Number:Int
var PokerName:String
var Suit:String
}

建立出52張牌

var numbers = ["1","2","3","4","5","6","7","8","9","10","11","12","13"]
var suits = ["clubs","diamonds","hearts","spades"]
var pokerImageName = ""
var card:PokerCards?
var cardArray = [PokerCards(Level: 1, Number: 1, PokerName: "clubs1", Suit: "clubs")]
func pokerFunc()-> [PokerCards] {
for i in 0 ..< suits.count {
for j in 0 ..< numbers.count {
pokerImageName = suits[i] + numbers[j]
card = PokerCards(Level: i+1 , Number: j+1 , PokerName: pokerImageName, Suit: suits[i] )
if let card = card {
cardArray += [card]
}
}
}
cardArray.removeFirst()
return cardArray
}

起始洗牌

override func viewDidLoad() {
super.viewDidLoad()
cardArray = pokerFunc()
cardArray.shuffle()
}

接著要發牌分配，先發玩家牌，再發莊家牌 ，並且加上分數計算

（以下都接近土法煉鋼，而且很混亂）

var z = 0
var y = 5
var k = 0
var player = 0
var playerA = 0
var bank = 0
var bankA = 0
func dealOneFunc(){
var playerPoint = cardArray[k].Number
if cardArray[k].Number > 10 {
playerPoint = 10
}else if cardArray[k].Number == 1 {
playerPoint = 11
playerA += 1
}
player += playerPoint
pokers[z].alpha = 1
pokers[z].image = UIImage(named:cardArray[k].PokerName)
k += 1
if bank < 17 || bank < player, player <= 21 {
var bankPoint = cardArray[k].Number
if cardArray[k].Number > 10 {
bankPoint = 10
}else if cardArray[k].Number == 1 {
bankPoint = 11
bankA += 1
}
pokers[y].alpha = 1
pokers[y].image = UIImage(named: cardArray[k].PokerName)
bank += bankPoint
k += 1
y += 1
}
z += 1
}

結算結果輸贏（A記為11點，若會因A而爆牌則A可算為1點。)

func resultFunc(){
if player > 21, playerA != 0 {
player -= 10
playerA -= 1
}
if bank > 21, bankA != 0 {
bank -= 10
bankA -= 1
}
if player > 21{
resultLabel.text = "Bust! you lost"
resultLabel.textColor = UIColor.red
dealButton.isHidden = true
passButton.isHidden = true
}else if player == 21 {
if bank == player {
resultLabel.text = "Push"
resultLabel.textColor = UIColor.white
}else {
resultLabel.text = "you win!"
resultLabel.textColor = UIColor.yellow
dealButton.isHidden = true
passButton.isHidden = true
}
}else if player < 21 {
if player > bank {
resultLabel.text = "you win!"
resultLabel.textColor = UIColor.yellow
dealButton.isHidden = true
passButton.isHidden = true
}else if player <= bank, bank <= 21 {
resultLabel.text = "you lost"
resultLabel.textColor = UIColor.white
dealButton.isHidden = true
passButton.isHidden = true
}else if player <= bank, bank > 21 {
resultLabel.text = "you win!"
resultLabel.textColor = UIColor.yellow
dealButton.isHidden = true
passButton.isHidden = true
}
}
}

func bustFunc(){
if player > 21, playerA != 0 {
player -= 10
playerA -= 1
}
if bank > 21, bankA != 0 {
bank -= 10
bankA -= 1
}
if bank <= 21, player > 21{
resultLabel.text = "Bust! you lost"
resultLabel.textColor = UIColor.red
dealButton.isHidden = true
passButton.isHidden = true
}else if bank > 21, player <= 21 {
resultLabel.text = "you win!"
resultLabel.textColor = UIColor.yellow
dealButton.isHidden = true
passButton.isHidden = true
}else if bank > 21, player > 21{
resultLabel.text = "Bust! you lost"
resultLabel.textColor = UIColor.red
dealButton.isHidden = true
passButton.isHidden = true
}else if player == 21, bank < 21 {
resultLabel.text = "you win!"
resultLabel.textColor = UIColor.yellow
dealButton.isHidden = true
passButton.isHidden = true
}
}

判斷發完52張牌後的語法

func emptyFunc(){
if k >= 51 {
dealButton.isHidden = true
passButton.isHidden = true
k = 0
pokerBack.alpha = 0
resultLabel.text = "No cards!"
cardArray.shuffle()
}
}

發牌的func

emptyFunc()
if z < 4 {
dealOneFunc()
bustFunc()
}else if z == 4 {
dealOneFunc()
resultFunc()
}
else {
sender.isHidden = true
}

與發牌不同的passFunc

emptyFunc()
while bank < player {
if player <= 21, z < 4, bank < 21, k < 51 {
var bankPoint = cardArray[k].Number
if cardArray[k].Number > 10 {
bankPoint = 10
}else if cardArray[k].Number == 1 {
bankPoint = 11
bankA += 1
}
pokers[y].alpha = 1
pokers[y].image = UIImage(named: cardArray[k].PokerName)
y += 1
k += 1
bank += bankPoint
}
}
resultFunc()

重新開始

@IBAction func restarFunc(_ sender: UIButton) {
for i in 0...9 {
pokers[i].alpha = 0
}
dealButton.isHidden = false
passButton.isHidden = false
resultLabel.textColor = UIColor.black
resultLabel.text = "Black Jack"
z = 0
y = 5
player = 0
bank = 0
playerA = 0
bankA = 0
print( "已發張數" + String(k) )
pokerBack.alpha = 1
}

這次重點放在撲克花色的呈現以及分數的比較, 就沒有研究放入動畫了,但模擬過程中發生了幾次畫面當掉（不是死掉）,突然按任何地方都沒反應,不確定是xcode或是語法有問題導致的狀況.
