Python Pygame制作的游戏菜单
我不知道我将如何在我制作的游戏中实现游戏菜单，我正在考虑使用指示按钮和“玩游戏”按钮。有人能帮我弄清楚如何用pygame或livewires制作一个简单的菜单吗？提前感谢：） 这是我的游戏的完整代码：Python Pygame制作的游戏菜单,python,user-interface,menu,pygame,livewires,Python,User Interface,Menu,Pygame,Livewires,我不知道我将如何在我制作的游戏中实现游戏菜单，我正在考虑使用指示按钮和“玩游戏”按钮。有人能帮我弄清楚如何用pygame或livewires制作一个简单的菜单吗？提前感谢：） 这是我的游戏的完整代码： # Asteroid Dodger # Player must avoid asteroids # make the score a global variable rather than tied to the asteroid. import pygame from livewires imp

Pygbutton模块提供了一种在Pygame程序中创建按钮的方法。您可以通过“pip安装pygbutton”下载它。github上有演示：请尝试以下代码： 游戏菜单功能 您可以在游戏循环上方调用此菜单 按钮功能 Pygame没有按钮，但制作按钮非常容易
def button(x, y, w, h, inactive, active, action=None):
mouse = pygame.mouse.get_pos()
click = pygame.mouse.get_pressed()
if x + w > mouse[0] > x and y + h > mouse[1] > y:
gameDisplay.blit(active, (x, y))
if click[0] == 1 and action is not None:
action()
else:
gameDisplay.blit(inactive, (x, y))
#Example function call
button(340, 560, 400, 200, randomBtn, randomBtn_hover, random_func)
按钮（）- x：按钮的x坐标
- y：按钮的y坐标
- w：按钮宽度（以像素为单位）
- h：按钮高度（以像素为单位）
- 活动：按钮处于活动状态时的图片（例如，当鼠标悬停在按钮上方时）
- 非活动：按钮空闲时的图片
- 操作：按下按钮时要执行的功能
希望这有帮助在我的头顶上，我会使用一个外循环（game_running=True）来显示菜单。如果玩家选择“开始游戏”，则执行mainloop（）查看
#Example function call
button(340, 560, 400, 200, randomBtn, randomBtn_hover, random_func)
