Python 作为一种简洁、高效且功能强大的编程语言，在游戏开发领域有着广泛的应用。以下是一些使用 Python 开发的常见游戏类型及相关示例：
休闲游戏
– 《贪吃蛇》：这是一款经典的休闲游戏，玩家通过控制蛇的移动方向，使其在屏幕上不断吃食物并增长长度，同时要避免撞到自己的身体或边界。在 Python 中，可以使用 Pygame 库来实现。以下是一个简单的《贪吃蛇》游戏代码示例：
“`python
import pygame
import random
# 初始化 pygame
pygame.init()
# 屏幕尺寸
SCREEN_WIDTH = 400
SCREEN_HEIGHT = 400
# 颜色定义
WHITE = (255, 255, 255)
BLACK = (0, 0, 0)
# 创建屏幕
screen = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT))
pygame.display.set_caption(“贪吃蛇”)
# 蛇的初始位置和长度
snake_pos = [(100, 100), (90, 100), (80, 100)]
snake_body = [(100, 100), (90, 100), (80, 100)]
# 食物的初始位置
food_pos = (random.randrange(1, (SCREEN_WIDTH // 10)) * 10,
random.randrange(1, (SCREEN_HEIGHT // 10)) * 10)
food_spawn = True
# 移动方向
direction = “RIGHT”
change_to = direction
# 游戏时钟
clock = pygame.time.Clock()
# 游戏主循环
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
quit()

elif direction == “RIGHT”:

# 检查是否吃到食物

random.randrange(1, (SCREEN_HEIGHT // 10)) * 10)
food_spawn = True
# 绘制屏幕
screen.fill(BLACK)
for pos in snake_body:
pygame.draw.rect(screen, WHITE, pygame.Rect(pos[0], pos[1], 10, 10))
pygame.draw.rect(screen, WHITE, pygame.Rect(food_pos[0], food_pos[1], 10, 10))
pygame.display.flip()
# 控制游戏帧率
clock.tick(10)

角色扮演游戏（RPG）
– 《文字冒险游戏》：Python 可以轻松实现简单的文字冒险游戏，通过文本输入和输出与玩家进行交互。以下是一个简单的文字冒险游戏示例：
“`python
print(“你来到了一个神秘的森林。”)
print(“你看到两条路，左边的路看起来比较阴暗，右边的路看起来比较明亮。”)
choice = input(“你选择走哪条路？（左边/右边）：”)
if choice == “左边”:
print(“你走进了阴暗的路，遇到了一只巨大的蜘蛛。”)
print(“你可以选择战斗（战斗）或逃跑（逃跑）。”)
action = input(“你的选择：”)
if action == “战斗”:
print(“你与蜘蛛展开了激烈的战斗，最终你成功地击败了蜘蛛。”)
elif action == “逃跑”:
print(“你转身逃跑，幸运地避开了蜘蛛的攻击。”)
else:
print(“你做出了错误的选择，游戏结束。”)
elif choice == “右边”:
print(“你沿着明亮的路走，发现了一座古老的城堡。”)
print(“你可以选择进入城堡（进入）或继续前进（前进）。”)
action = input(“你的选择：”)
if action == “进入”:
print(“你进入了城堡，里面充满了各种宝藏和危险。”)
elif action == “前进”:
print(“你继续沿着路前进，发现了更多的神秘事物。”)
else:
print(“你做出了错误的选择，游戏结束。”)
else:
print(“你做出了错误的选择，游戏结束。”)
