我正在 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()

  1. 谁能给我一个可以学习pygame的资源链接。

  2. 在我的游戏中说，当我按下“q”然后它会暂停游戏，当我再次按下它时它会解冻任何人都可以给我建议如何做到这一点。我现在这有点含糊，但意思是每当按下“q”键时，它会阻止角色移动并且一切都停止。

暂停使或多或少像这样：

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()

编辑：

您在类中没有代码，因此您必须在没有代码的PAUSED情况下使用self.

http://www.pygame.org/wiki/tutorials 看起来是一些教程的好地方。我不确定您寻找的高级程度，所以它们可能有点基本。乍一看，这看起来不错：http ://programarcadegames.com/index.php?chapter=bitmapped_graphics_and_sound&lang=en#section_12

这可能是一种非常笨拙的方式，但您可以创建一个无限循环，直到您再次按下 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。

默认的 Punch the chimp 教程是一个很好的起点。具体来说，你应该看看他们使用 pygame.time.Clock.tick 来限制帧率。

一旦你有一个游戏循环，最简单的暂停方法是使用“event.wait()”，它会停止并等待事件发生。您只需使用它等待直到按下取消暂停，然后继续事件循环。
