问题描述
所以,我找到了一个 Tech 和 Tim 的视频,他在那里创建了一个飞扬的小鸟 py 文件。好吧,我的问题是 pygame 窗口在运行后没有弹出。我正在使用 ubuntu 20.04 .. 搜索解决方案,并混合了我学到的所有东西,因为我是 pygame 的完整初学者..需要帮助:(
import os
import pygame
pygame.init()

WIN_WIDTH = 600
WIN_HEIGHT = 800
BIRD_IMGS = [pygame.transform.scale2x(pygame.image.load(os.path.join("imgs","bird1.png"))),pygame.transform.scale2x(pygame.image.load(os.path.join("imgs","bird2.png"))),"bird3.png")))]
PIPE_IMG = pygame.transform.scale2x(pygame.image.load(os.path.join("imgs","pipe.png")))
BASE_IMG = pygame.transform.scale2x(pygame.image.load(os.path.join("imgs","base.png")))
BG_IMG = pygame.transform.scale2x(pygame.image.load(os.path.join("imgs","bg.png")))
class Bird:
IMGS = BIRD_IMGS
MAX_ROTATION = 25
ROTATION_VELociTY = 20
ANIMATION_TIME = 5
def __init__(self,x,y):
self.x = x
self.y = y
self.tilt = 0
self.tick_count = 0
self.vel = 0
self.height = self.y
self.img_count = 0
self.img = self.IMGS[0]
def jump(self):
self.vel = -10.5
self.tick_count = 0
self.height = self.y
def move(self):
self.tick_count += 1
d = self.vel * self.tick_count + 1.5*self.tick_count**2
if d >= 16:
d = 16
if d < 0:
d -= 2
self.y = self.y + d
if d < 0 or self.y < self.height + 50:
if self.tilt < self.MAX_ROTATION:
self.tilt = self.MAX_ROTATION
else:
self.tilt > -90
self.tilt -= self.ROTATION_VELociTY
def draw(self,win):
self.img_count += 1
if self.img_count < self.ANIMATION_TIME:
self.img = self.IMGS[0]
elif self.img_count < self.ANIMATION_TIME*2:
self.img = self.IMGS[1]
elif self.img_count < self.ANIMATION_TIME*3:
self.img = self.IMGS[2]
elif self.img_count == self.ANIMATION_TIME*4:
self.img = self.IMGS[1]
elif self.img_count < self.ANIMATION_TIME*4+1:
self.img = self.IMGS[0]
self.img_count = 0
if self.tilt <= -80:
self.img = self.IMGS[1]
self.img_count = self.ANIMATION_TIME*2
rotated_image = pygame.transform.rotate(self.img,self.tilt)
new_rect = rotated_image.get_rect(center=self.img.get_rect(topleft = (self.x,self.y)).center)
win.blit(rotated_image,new_rect.topleft)
def get_mask(self):
return pygame.mask.from_surface(self.img)
def draw_window(win,bird):
win.blit(BG_IMG,(0,0))
bird.draw(win)
pygame.display.update()
def main():
bird = Bird(200,200)
win = pygame.display.set_mode((WIN_WIDTH,WIN_HEIGHT))
run = True
while run:
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
draw_window(win,bird)
pygame.quit()
quit()
main()
我得到的回溯是:
Traceback (most recent call last):
File "/home/user/Python/Flappybird-Ai/flappy_bird.py",line 98,in <module>
main()
File "/home/user/Python/Flappybird-Ai/flappy_bird.py",line 85,in main
win = pygame.display.set_mode((WIN_WIDTH,WIN_HEIGHT))
pygame.error: No available video device
解决方法
os.environ["SDL_VIDEODRIVER"] = "dummy"
这一行让 pygame 使用它的“dummy”,意思是“假的”,视频驱动程序。
使用伪造的视频驱动程序,当然不会出现窗口。尝试将其删除。
