Question

我在pygame中为android制作游戏，这是我的代码：

import pygame, sys
from pygame.locals import * 

try:
    import Android
except ImportError:
    Android = None

pygame.init()

if Android:
    android.init()
    android.map_key(android.KEYCODE_BACK, pygame.K_ESCAPE)

size = width, height = 1276,650
screen = pygame.display.set_mode(size)

r = 0
bif = pygame.image.load("map.png") 
pygame.display.set_caption("Pygame 2D RPG !")
x,y=0,0
movex, movey=0,0
character="boy.png"
player=pygame.image.load(character).convert_alpha()

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()
        if event.type==KEYDOWN:
            if event.key==K_a:
                movex=-1
            elif event.key==K_d:
                movex=+1
            elif event.key==K_w:
                movey=-1
            elif event.key==K_s:
                movey=+1
        if event.type==KEYUP:
            if event.key==K_a:
                movex=0
            elif event.key==K_d:
                movex=0
            elif event.key==K_w:
                movey=0
            elif event.key==K_s:
                movey=0
            elif event.type == KEYDOWN:
                if event.key == K_ESCAPE:
                    pygame.quit()
                    sys.exit()
    x+=movex
    y+=movey
    screen.fill((r,0,0))
    screen.blit(bif,(0,0))
    screen.blit(player,(x,y)) 

    pygame.display.update()

任何人都可以给我一个资源链接，我可以学习pygame。
当我按下“q”时，在我的游戏中说它然后暂停游戏，当我再次按下它时，解冻可以让任何人给我一个如何做到这一点的建议。我现在这有点模糊，但是什么意思是每当按下“q”键时它就会阻止角色移动而一切都停止。

暂停或多或少会像这样：

self.PAUSED = False

while True:
    for event in pygame.event.get():
        if event.type==KEYDOWN:
            if event.key==K_q:
                self.PAUSED = not self.PAUSED


    if not self.PAUSED:

        x+=movex
        y+=movey
        screen.fill((r,0,0))
        screen.blit(bif,(0,0))
        screen.blit(player,(x,y)) 

        pygame.display.update()

修改

您没有类中的代码，因此必须使用PAUSED而不使用self.

使用暂停的屏幕和键盘以及“PAUSED”文本的工作代码

import pygame, sys from pygame.locals import * try: import Android except ImportError: Android = None pygame.init() if Android: android.init() android.map_key(android.KEYCODE_BACK, pygame.K_ESCAPE) size = width, height = 1276,650 screen = pygame.display.set_mode(size) r = 0 bif = pygame.image.load("map.png") pygame.display.set_caption("Pygame 2D RPG !") x,y=0,0 movex, movey=0,0 character="boy.png" player=pygame.image.load(character).convert_alpha() PAUSED = False font = pygame.font.SysFont("serif", 72) text_paused = font.render("PAUSED", True, (255, 0, 0)) while True: # --- events --- for event in pygame.event.get(): if event.type == pygame.QUIT: pygame.quit() sys.exit() if event.type==KEYDOWN: if event.key == K_ESCAPE: pygame.quit() sys.exit() elif event.key==K_q: PAUSED = not PAUSED if not PAUSED: if event.type==KEYDOWN: if event.key==K_a: movex=-1 elif event.key==K_d: movex=+1 elif event.key==K_w: movey=-1 elif event.key==K_s: movey=+1 if event.type==KEYUP: if event.key==K_a: movex=0 elif event.key==K_d: movex=0 elif event.key==K_w: movey=0 elif event.key==K_s: movey=0 # --- changing values --- if not PAUSED: x+=movex y+=movey # --- drawing --- screen.fill((r,0,0)) screen.blit(bif,(0,0)) screen.blit(player,(x,y)) if PAUSED: screen.blit(text_paused, (100, 100)) pygame.display.update()

http://www.pygame.org/wiki/tutorials 看起来像是一些教程的好地方。我不确定你的寻找有多先进，所以它们可能有点基础。乍一看，这看起来很不错：http://programarcadegames.com/index.php?chapter=bitmapped_graphics_and_sound&lang=en#section_12

这可能是一种非常笨重的方式，但你可以创建一个重复的无限循环，直到你再次按q键：

if <q key pressed>:
    while 1:
        sleep(1)
        if <q key pressed>:
             break

是一个相当简化的版本。

默认Punch the chimp tutorial是一个非常好的起点。具体来说，你应该看看他们使用pygame.time.Clock.tick来限制帧速率。

一旦你有游戏循环，最简单的暂停方法是使用“event.wait（）”，它会停止并等待直到事件发生。您只需使用它来等待按下取消暂停，然后继续事件循环。

Pygame暂停键
