我正在為學(xué)校作業(yè)制作搖滾、紙、剪刀游戲，但是當(dāng)我嘗試運(yùn)行此腳本時(shí)，游戲無(wú)法正常運(yùn)行。例如，當(dāng)我單擊 Rock 時(shí)，計(jì)算機(jī)只會(huì)選擇相同或選擇紙張。但玩家永遠(yuǎn)不會(huì)贏。我不知道如何解決這個(gè)問(wèn)題，我已經(jīng)嘗試了幾個(gè)小時(shí)。這是我的代碼：public partial class MainWindow : Window{ string Computer; string[] computer = { "Rock", "Paper", "Scissors" }; Random random = new Random(); int RandomType; string PlayerPicks; public MainWindow() { InitializeComponent(); } private void StoneButton_Click(object sender, RoutedEventArgs e) { PlayerPicks = "Rock"; RandomType = random.Next(0, 2); Computer = computer[RandomType]; Game(); } private void PaperButton_Click(object sender, RoutedEventArgs e) { PlayerPicks = "Paper"; RandomType = random.Next(0, 2); Computer = computer[RandomType]; Game(); } private void ScissorsButton_Click(object sender, RoutedEventArgs e) { PlayerPicks = "Scissors"; RandomType = random.Next(0, 2); Computer = computer[RandomType]; Game(); } void Game() { string message = "The winner is: "; string computerWins = "Computer!"; string playerWins = "Player!"; string draw = "N-Nobody?"; if (PlayerPicks == "Rock" && Computer == "Paper") // Player: Rock, Computer: paper = computer wins { MessageBox.Show(message + computerWins); } else if (PlayerPicks == "Rock" && Computer == "Scissors") // Player: Rock, Computer: Scissors = Player wins { MessageBox.Show(message + playerWins); }

問(wèn)題 1
RandomType = random.Next(0, 2)只生成一個(gè)介于 0 和 1 之間的數(shù)字，您需要這樣做RandomType = random.Next(0, 3)這將生成一個(gè)介于 0 和 2 之間的數(shù)字
問(wèn)題 2
if (PlayerPicks == "Scissors" && Computer == "Scissor")檢查計(jì)算機(jī)是否選擇Scissor而不是Scissors只需將其更改為if (PlayerPicks == "Scissors" && Computer == "Scissors")

這是另一種方法。它已從您的代碼中進(jìn)行了極大的重構(gòu)。首先，我在表單類(lèi)中添加了一個(gè)私有System.Random成員字段：
private Random _rand = new Random();
然后，我設(shè)置了兩個(gè)enums，一個(gè)用于“手勢(shì)”（石頭、紙、剪刀），另一個(gè)用于結(jié)果：
public enum HandSign
{
Rock, // rock beats scissors
Paper, // paper beats rock
Scissors, // scissors beats paper
}
public enum Result
{
Draw,
ComputerWins,
PlayerWins
}
然后我創(chuàng)建了一些輔助函數(shù)，首先確定計(jì)算機(jī)的下一步動(dòng)作：
private HandSign GetRandomPlay()
{
var result = _rand.Next(0, Enum.GetValues(typeof(HandSign)).Length);
return (HandSign) result;
}
接下來(lái)是確定獲勝者的規(guī)則引擎：
private Result DetermineWinner(HandSign player, HandSign computer)
{
if (player == computer)
{
return Result.Draw;
}
if (player == HandSign.Scissors && computer == HandSign.Rock)
{
return Result.ComputerWins;
}
if (player == HandSign.Rock && computer == HandSign.Scissors)
{
return Result.PlayerWins;
}
if (player > computer)
{
return Result.PlayerWins;
}
//finally, otherwise
return Result.ComputerWins;
}
最后來(lái)一張“玩游戲”，在表格上的一把標(biāo)簽上展示了玩的結(jié)果：
private void PlayGame(HandSign playerPicks)
{
PlayerPicksLbl.Text = playerPicks.ToString();
var computerPicks = GetRandomPlay();
ComputerPicksLbl.Text = computerPicks.ToString();
WinnerLbl.Text = DetermineWinner(playerPicks, computerPicks).ToString();
}
那時(shí)，我的三個(gè)按鈕單擊處理程序看起來(lái)像這樣（這是 Rock 處理程序）：
private void RockBtn_Click(object sender, EventArgs e)
{
PlayGame(HandSign.Rock);
}
以這種方式構(gòu)造事物的一個(gè)結(jié)果是將其擴(kuò)展到“Rocks, Paper, Scissors, Lizard, Spock”，您需要做的就是向枚舉添加兩個(gè)條目，向兩個(gè)條目添加HandSign更多邏輯DetermineWinner更多按鈕/按鈕處理程序。
另請(qǐng)注意，沒(méi)有辦法拼錯(cuò)“剪刀”，仍然可以編譯！

在 Random.Next 上，上限是獨(dú)占的，所以你應(yīng)該這樣做 RandomType = random.Next(0, 3);
此外在：
if (PlayerPicks == "Scissors" && Computer == "Scissor")你有“Scissor”而不是“Scissor s ”
