Python 遊戲開發實戰：100 個項目從入門到進階

講解：這裡使用了 random 模組生成隨機數，並通過 while 循環控制遊戲流程。玩家有 10 次機會，程式會根據輸入給出提示。注意加入了 try-except 處理非數字輸入，增強了魯棒性。

2. 文字冒險遊戲

這類遊戲依賴於狀態機和分支邏輯，玩家的選擇直接影響劇情走向。

import time

def text_adventure():
    print("========== 神秘古堡探險 ==========")
    print("你站在一座古老城堡的大門前。")
    time.sleep(1)
    # 第一選擇
    print("\n你要：")
    print("1. 敲門")
    print("2. 嘗試推開大門")
    print("3. 繞到城堡後面")
    choice1 = input("請選擇 (1-3): ")
    
    if choice1 == "1":
        print("\n你輕輕敲了敲門。")
        time.sleep(1)
        print("門吱呀一聲開了，但裡面一片漆黑。")
        print("\n你要：")
        print("1. 進入城堡")
        print("2. 離開")
        choice1a = input("請選擇 (1-2): ")
        if choice1a == "1":
            print("\n你走進城堡，門在你身後關上了。")
            time.sleep(1)
            print("你聽到遠處傳來奇怪的聲音...")
            time.sleep(1)
            print("突然，一盞燈亮了起來！")
            time.sleep(1)
            print("你發現自己站在一個豪華的大廳裡。")
            print("恭喜！你成功進入了城堡！")
        else:
            print("\n你決定離開。遊戲結束。")
    elif choice1 == "2":
        print("\n你用力推門，但門紋絲不動。")
        time.sleep(1)
        print("你注意到門上有一個小鑰匙孔。")
        time.sleep(1)
        print("你需要找到鑰匙才能進入。")
        print("遊戲結束。")
    elif choice1 == "3":
        print("\n你繞到城堡後面。")
        time.sleep(1)
        print("你發現一扇破損的窗戶。")
        print("\n你要：")
        print("1. 從窗戶爬進去")
        print("2. 返回前門")
        choice1c = input("請選擇 (1-2): ")
        if choice1c == "1":
            print("\n你從窗戶爬進了城堡。")
            time.sleep(1)
            print("但你不小心觸發了警報！")
            time.sleep(1)
            print("守衛發現了你，遊戲結束。")
        else:
            print("\n你返回前門，重新考慮你的選擇。")
            text_adventure()
    
    play_again = input("\n再玩一次？(y/n): ").lower()
    if play_again == 'y':
        text_adventure()

if __name__ == "__main__":
    text_adventure()

講解：通過嵌套的 if-elif-else 結構實現故事分支。time.sleep() 用於營造懸念感。這種結構雖然簡單，但構建複雜劇情的基礎。

3. 簡單計算機遊戲

結合數學運算與計分系統，適合兒童教育場景。

import random
import time

def math_game():
    print("========== 數學挑戰遊戲 ==========")
    print("回答下列數學問題，看看你能得多少分！")
    score = 0
    total_questions = 5
    operations = ['+', '-', '*']
    difficulty = input("選擇難度 (簡單/中等/困難): ").lower()
    
    if difficulty == '困難':
        max_num = 100
    elif difficulty == '中等':
        max_num = 50
    else: # 簡單
        max_num = 20
    
    for i in range(1, total_questions + 1):
        num1 = random.randint(1, max_num)
        num2 = random.randint(1, max_num)
        operation = random.choice(operations)
        
        if operation == '+':
            correct_answer = num1 + num2
        elif operation == '-':
            correct_answer = num1 - num2
        else: # '*'
            correct_answer = num1 * num2
        
        print(f"\n問題 {i}/{total_questions}:")
        print(f"{num1} {operation} {num2} = ?")
        
        start_time = time.time()
        try:
            player_answer = int(input("你的答案："))
        except ValueError:
            print("請輸入有效的數字！")
            player_answer = None
            continue
            
        answer_time = time.time() - start_time
        
        if player_answer == correct_answer:
            print("正確！")
            if answer_time < 3:
                score += 10
                print(f"快速回答！+10 分 (用時：{answer_time:.1f}秒)")
            elif answer_time < 10:
                score += 5
                print(f"不錯！+5 分 (用時：{answer_time:.1f}秒)")
            else:
                score += 2
                print(f"正確但有點慢，+2 分 (用時：{answer_time:.1f}秒)")
        else:
            print(f"錯誤！正確答案是：{correct_answer}")
            print(f"用時：{answer_time:.1f}秒")
    
    print(f"\n{'='*30}")
    print(f"遊戲結束！你的總分：{score}/{total_questions*10}")
    percentage = (score / (total_questions * 10)) * 100
    
    if percentage >= 90:
        print("太棒了！你是數學天才！")
    elif percentage >= 70:
        print("做得好！你的數學很棒！")
    elif percentage >= 50:
        print("不錯！繼續練習會更好！")
    else:
        print("需要多加練習數學哦！")
    
    play_again = input("\n再玩一次？(y/n): ").lower()
    if play_again == 'y':
        math_game()

if __name__ == "__main__":
    math_game()

講解：此例展示了如何根據答題時間動態調整分數，增加了遊戲的趣味性。同時通過難度參數控制數字範圍，實現了可配置性。

4. 文字版貪吃蛇

使用 ASCII 字符在終端模擬經典遊戲，涉及類封裝與狀態管理。

import os
import sys
import time
import random
import msvcrt # Windows 專用

def clear_screen():
    os.system('cls' if os.name == 'nt' else 'clear')

class TextSnake:
    def __init__(self, width=20, height=10):
        self.width = width
        self.height = height
        self.snake = [(height//2, width//4)]
        self.food = self.generate_food()
        self.direction = 'RIGHT'
        self.score = 0
        self.game_over = False

    def generate_food(self):
        while True:
            food = (random.randint(0, self.height-1), random.randint(0, self.width-1))
            if food not in self.snake:
                return food

    def draw(self):
        clear_screen()
        print("=" * (self.width + 2))
        print("文字版貪吃蛇 - 使用 WASD 移動，Q 退出")
        print(f"分數：{self.score}")
        print("=" * (self.width + 2))
        
        for i in range(self.height):
            row = [' '] * self.width
            for segment in self.snake:
                if segment[0] == i:
                    if segment == self.snake[0]:
                        row[segment[1]] = 'O'
                    else:
                        row[segment[1]] = 'o'
            if self.food[0] == i:
                row[self.food[1]] = '*'
            print('|' + ''.join(row) + '|')
        print("=" * (self.width + 2))
        if self.game_over:
            print("遊戲結束！")
            print(f"最終分數：{self.score}")

    def get_input(self):
        if msvcrt.kbhit():
            key = msvcrt.getch().decode('utf-8', errors='ignore').lower()
            if key == 'q':
                self.game_over = True
            elif key == 'w' and self.direction != 'DOWN':
                self.direction = 'UP'
            elif key == 's' and self.direction != 'UP':
                self.direction = 'DOWN'
            elif key == 'a' and self.direction != 'RIGHT':
                self.direction = 'LEFT'
            elif key == 'd' and self.direction != 'LEFT':
                self.direction = 'RIGHT'

    def update(self):
        if self.game_over:
            return
        head = self.snake[0]
        if self.direction == 'UP':
            new_head = (head[0] - 1, head[1])
        elif self.direction == 'DOWN':
            new_head = (head[0] + 1, head[1])
        elif self.direction == 'LEFT':
            new_head = (head[0], head[1] - 1)
        else: # RIGHT
            new_head = (head[0], head[1] + 1)
        
        if (new_head[0] < 0 or new_head[0] >= self.height or new_head[1] < 0 or new_head[1] >= self.width):
            self.game_over = True
            return
        if new_head in self.snake:
            self.game_over = True
            return
        
        self.snake.insert(0, new_head)
        if new_head == self.food:
            self.score += 10
            self.food = self.generate_food()
        else:
            self.snake.pop()

    def run(self):
        while not self.game_over:
            self.draw()
            self.get_input()
            self.update()
            time.sleep(0.2)
        self.draw()
        print("\n按任意鍵退出...")
        msvcrt.getch()

if __name__ == "__main__":
    if os.name != 'nt':
        print("此遊戲需要 Windows 系統 (使用 msvcrt 模組)")
        print("在 Linux/Mac 上，可以使用 curses 模組替代")
        sys.exit(1)
    game = TextSnake(20, 10)
    game.run()

講解：這是一個完整的類封裝示例。msvcrt 用於獲取無回顯按鍵，實現即時反饋。注意跨平台兼容性，Linux 下需替換為 curses 或 getch 庫。

5. 井字遊戲（Tic-Tac-Toe）

雙人策略遊戲，重點在於棋盤狀態檢查與平局判斷。

import os

def clear_screen():
    os.system('cls' if os.name == 'nt' else 'clear')

class TicTacToe:
    def __init__(self):
        self.board = [' ' for _ in range(9)]
        self.current_player = 'X'
        self.winner = None
        self.game_over = False

    def draw_board(self):
        clear_screen()
        print("========== 井字遊戲 ==========")
        print("玩家：X 和 O")
        print("位置對應數字鍵盤:")
        print(" 7 | 8 | 9 ")
        print("---+---+---")
        print(" 4 | 5 | 6 ")
        print("---+---+---")
        print(" 1 | 2 | 3 ")
        print("\n當前棋盤:")
        print(f" {self.board[6]} | {self.board[7]} | {self.board[8]} ")
        print("---+---+---")
        print(f" {self.board[3]} | {self.board[4]} | {self.board[5]} ")
        print("---+---+---")
        print(f" {self.board[0]} | {self.board[1]} | {self.board[2]} ")
        print(f"\n當前玩家：{self.current_player}")

    def make_move(self, position):
        if self.board[position] == ' ' and not self.game_over:
            self.board[position] = self.current_player
            self.check_winner()
            if not self.game_over:
                self.current_player = 'O' if self.current_player == 'X' else 'X'
            return True
        return False

    def check_winner(self):
        winning_combinations = [
            [0, 1, 2], [3, 4, 5], [6, 7, 8], # 橫向
            [0, 3, 6], [1, 4, 7], [2, 5, 8], # 縱向
            [0, 4, 8], [2, 4, 6] # 對角線
        ]
        for combo in winning_combinations:
            a, b, c = combo
            if self.board[a] == self.board[b] == self.board[c] != ' ':
                self.winner = self.board[a]
                self.game_over = True
                return
        if ' ' not in self.board:
            self.game_over = True

    def play(self):
        while not self.game_over:
            self.draw_board()
            try:
                move = int(input(f"玩家 {self.current_player}，請選擇位置 (1-9): "))
                if move < 1 or move > 9:
                    print("無效位置！請輸入 1-9 之間的數字。")
                    input("按 Enter 繼續...")
                    continue
                position = move - 1
                if not self.make_move(position):
                    print("該位置已被佔用！請選擇其他位置。")
                    input("按 Enter 繼續...")
            except ValueError:
                print("無效輸入！請輸入 1-9 之間的數字。")
                input("按 Enter 繼續...")
        
        self.draw_board()
        if self.winner:
            print(f"恭喜！玩家 {self.winner} 獲勝！")
        else:
            print("平局！")
        
        play_again = input("\n再玩一次？(y/n): ").lower()
        if play_again == 'y':
            new_game = TicTacToe()
            new_game.play()

if __name__ == "__main__":
    game = TicTacToe()
    game.play()

講解：利用列表索引映射數字鍵盤位置，簡化了輸入處理。check_winner 函數預定義了所有連線組合，效率高且易於維護。

(註：由於篇幅限制，後續基礎遊戲如記憶配對、問答、迷宮等原理類似，均採用上述模式進行狀態管理與交互設計)

第二部分：簡單圖形遊戲（21-50）

此部分引入 Pygame 庫，實現真正的圖形界面與動畫效果。
