如前所述通過ecline6,鳥是你最擔心的在這一點上。
考慮閱讀this book ..
現在,首先,讓我們清理你的代碼...
import pygame
import os
# let's address the class a little later..
pygame.init()
screen = pygame.display.set_mode((640, 400))
# you only need to call the following once,so pull them out of the while loop.
bird = pygame.image.load(os.path.join('C:\Python27', 'player.png'))
clock = pygame.time.Clock()
running = True
while running:
event = pygame.event.poll()
if event.type == pygame.QUIT:
running = False
screen.fill((255, 255, 255)) # fill the screen
screen.blit(bird, (0, 0)) # then blit the bird
pygame.display.update() # Just do one thing, update/flip.
clock.tick(40) # This call will regulate your FPS (to be 40 or less)
現在,您的「鳥」是不動的原因是:
當你的blit圖像,即:screen.blit(bird, (0, 0))
,
的(0,0)
是恆定的,所以它不會移動。
下面是最後的代碼,你想要的輸出(嘗試)並閱讀註釋:
import pygame
import os
# it is better to have an extra variable, than an extremely long line.
img_path = os.path.join('C:\Python27', 'player.png')
class Bird(object): # represents the bird, not the game
def __init__(self):
""" The constructor of the class """
self.image = pygame.image.load(img_path)
# the bird's position
self.x = 0
self.y = 0
def handle_keys(self):
""" Handles Keys """
key = pygame.key.get_pressed()
dist = 1 # distance moved in 1 frame, try changing it to 5
if key[pygame.K_DOWN]: # down key
self.y += dist # move down
elif key[pygame.K_UP]: # up key
self.y -= dist # move up
if key[pygame.K_RIGHT]: # right key
self.x += dist # move right
elif key[pygame.K_LEFT]: # left key
self.x -= dist # move left
def draw(self, surface):
""" Draw on surface """
# blit yourself at your current position
surface.blit(self.image, (self.x, self.y))
pygame.init()
screen = pygame.display.set_mode((640, 400))
bird = Bird() # create an instance
clock = pygame.time.Clock()
running = True
while running:
# handle every event since the last frame.
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit() # quit the screen
running = False
bird.handle_keys() # handle the keys
screen.fill((255,255,255)) # fill the screen with white
bird.draw(screen) # draw the bird to the screen
pygame.display.update() # update the screen
clock.tick(40)
哇,鳥是你最擔心的在這一點上。你有一個循環,每次都加載鳥。你正在調用遊戲類,就像它是一個函數。你甚至還沒有初始化pygame。在理解遊戲循環之前,不要考慮移動和用戶輸入。 – ecline6 2013-04-24 04:28:45
是啊我真的搞不清這一切m特很新,它 – Serial 2013-04-24 04:29:53
我建議通過一些在pygame的網站上的教程去。 http://www.pygame.org/wiki/tutorials此外,在Python中,類一些清新,和控制流的想法是一個好主意了。順便提一句,你的K_UP和K_DOWN事件永遠不會被讀取,因爲你的遊戲被卡在上面的循環中。如果註釋掉while循環,腳本將不會運行。但是,不要專注於此。去找你一個教程吧! :) – ecline6 2013-04-24 04:33:07
