[英]Pygame menu is not working properly
I am trying to make a python game with a menu.我正在尝试使用菜单制作 python 游戏。 The game is quite simple, but works well on its own.
游戏非常简单,但单独运行效果很好。 However, when I created this menu, it works fine as well UNTIL I include the game itself.
但是,当我创建此菜单时,它也能正常工作,直到我包含游戏本身。 It runs the game, and then launches the menu at the same time.
它运行游戏,然后同时启动菜单。 The idea is to launch the menu and have options start and quit: start launches the game, quit quits.
这个想法是启动菜单并有选项开始和退出:开始启动游戏,退出退出。
Here is the menu code:这是菜单代码:
#!/usr/bin/python
import sys
import pygame
import os
pygame.init()
WHITE = (255, 255, 255)
RED = (255, 0, 0)
BLACK = (0, 0, 0)
class MenuItem(pygame.font.Font):
def __init__(self, text, font=None, font_size=30,
font_color=WHITE, (pos_x, pos_y)=(0, 0)):
pygame.font.Font.__init__(self, font, font_size)
self.text = text
self.font_size = font_size
self.font_color = font_color
self.label = self.render(self.text, 1, self.font_color)
self.width = self.label.get_rect().width
self.height = self.label.get_rect().height
self.dimensions = (self.width, self.height)
self.pos_x = pos_x
self.pos_y = pos_y
self.position = pos_x, pos_y
def is_mouse_selection(self, (posx, posy)):

# t_h: total height of text block
t_h = len(items) * menu_item.height
pos_x = (self.scr_width / 2) - (menu_item.width / 2)
pos_y = (self.scr_height / 2) - (t_h / 2) + (index * menu_item.height)
menu_item.set_position(pos_x, pos_y)
self.items.append(menu_item)

pygame.mouse.set_visible(False)
def set_keyboard_selection(self, key):
"""

"""
for item in self.items:
# Return all to neutral
item.set_italic(False)
item.set_font_color(WHITE)
if self.cur_item is None:
self.cur_item = 0

if key == pygame.K_UP and \
self.cur_item > 0:

if item.is_mouse_selection(mpos):

def run(self):

for event in pygame.event.get():

if event.type == pygame.KEYDOWN:

self.screen.blit(item.label, item.position)
pygame.display.flip()
if __name__ == "__main__":
# Creating the screen
screen = pygame.display.set_mode((640, 480), 0, 32)
menu_items = ('Start', 'Quit')
funcs = {'Start': os.system("python game.py"),
'Quit': sys.exit}
pygame.display.set_caption('Badger Defense')
gm = BadgerDefense(screen, funcs.keys(), funcs)
gm.run()
There's no need eate a class for a menu, a function will do.没有必要为菜单吃一个类,一个函数就可以了。 For example:
例如:
def game_menu():
menu = True
while menu:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
quit()
gameDisplay.fill(white)
titleText = gameDisplay.blit(title, (170, 200)) # Title is an image
titleText.center = ((display_width / 2), (display_height / 2))
pygame.display.update()
clock.tick(15)
and then call the menu right above your game loop.然后调用游戏循环正上方的菜单。
