我正在尝试在PyGame中创建一个'Runner'风格的游戏(如Geometry Dash),背景不断移动。到目前为止一切正常,但背景图像的渲染限制帧速率超过每秒35帧。在我添加无限/重复背景元素之前,它可以轻松地以60 fps运行。这两行代码负责(删除后,游戏可以60 + fps运行):
screen.blit(bg,(bg_x,0))| screen.blit(bg,(bg_x2,0))
我能做些什么来让游戏跑得更快?提前谢谢!
简化源代码:
import pygame
pygame.init()
screen = pygame.display.set_mode((1000,650), 0, 32)
clock = pygame.time.Clock()
def text(text, x, y, color=(0,0,0), size=30, font='Calibri'): # blits text to the screen
text = str(text)
font = pygame.font.SysFont(font, size)
text = font.render(text, True, color)
screen.blit(text, (x, y))
def game():
bg = pygame.image.load('background.png')
bg_x = 0 # stored positions for the background images
bg_x2 = 1000
pygame.time.set_timer(pygame.USEREVENT, 1000)
frames = 0 # counts number of frames for every second
fps = 0
while True:
frames += 1
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
quit()
if event.type == pygame.USEREVENT: # updates fps every second
fps = frames
frames = 0 # reset frame count
bg_x -= 10 # move the background images
bg_x2 -= 10
if bg_x == -1000: # if the images go off the screen, move them to the other end to be 'reused'
bg_x = 1000
elif bg_x2 == -1000:
bg_x2 = 1000
screen.fill((0,0,0))
screen.blit(bg, (bg_x, 0))
screen.blit(bg, (bg_x2, 0))
text(fps, 0, 0)
pygame.display.update()
#clock.tick(60)
game()

您是否尝试过使用convert()
?
bg = pygame.image.load('background.png').convert()
您经常需要在没有参数的情况下调用Surface.convert(),以创建一个可以在屏幕上更快地绘制的副本。
对于Alpha透明度,与.png图像一样,在加载后使用convert_alpha()方法,以使图像具有每像素透明度。
