我用pygame用python做了一个很简单的游戏,不知道为什么会卡顿,有人可以帮帮我吗?
我试图自己修复它,但我不能,我也找不到在线修复它的方法。
这不是因为我的电脑,它有 16 GB 的 RAM、512 GB 的固态硬盘、处理器:英特尔酷睿 i7-7600U 2.90 GHz。
这是代码:
import pygame
pygame.init()
win = pygame.display.set_mode((500, 500))
pygame.display.set_caption("Platformer")
colour = (255, 0, 0) # Colour red
x = 50
y = 50
width = 40
height = 60
vel = 5
isJump = False
jumpCount = 10
run = True
while run:
pygame.time.delay(100)
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
keys = pygame.key.get_pressed()
if keys[pygame.K_LEFT] and x > vel:
x = x - vel
if keys[pygame.K_RIGHT] and x < 500 - width - vel:
x = x + vel
if not(isJump):
if keys[pygame.K_UP] and y > vel:
y = y - vel
if keys[pygame.K_DOWN] and y < 500 - height - vel:
y = y + vel
if keys[pygame.K_SPACE]:
isJump = True
else:
if jumpCount >= -10:
neg = 1
if jumpCount < 0:
neg = -1
y = y - (jumpCount ** 2) * 0.5 * neg
jumpCount = jumpCount - 1
else:
isJump = False
jumpCount = 10
win.fill((0, 0, 0))
pygame.draw.rect(win, colour, (x, y, width, height))
pygame.display.update()
pygame.quit()
答案 0 :(得分:0)
应用程序滞后,因为应用程序循环中的延迟很大。删除延迟:
pygame.time.delay(100)
使用 pygame.time.Clock
控制每秒帧数,从而控制游戏速度。
tick()
对象的方法 pygame.time.Clock
以这种方式延迟游戏,即循环的每次迭代消耗相同的时间段。见pygame.time.Clock.tick()
:
这个方法应该每帧调用一次。
这意味着循环:
<块引用>clock = pygame.time.Clock()
run = True
while run:
clock.tick(60)
每秒运行 60 次。
完整示例:
import pygame
pygame.init()
win = pygame.display.set_mode((500, 500))
pygame.display.set_caption("Platformer")
colour = (255, 0, 0) # Colour red
x = 50
y = 50
width = 40
height = 60
vel = 5
isJump = False
jumpCount = 10
clock = pygame.time.Clock()
run = True
while run:
clock.tick(60)
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
keys = pygame.key.get_pressed()
if keys[pygame.K_LEFT] and x > vel:
x = x - vel
if keys[pygame.K_RIGHT] and x < 500 - width - vel:
x = x + vel
if not(isJump):
if keys[pygame.K_UP] and y > vel:
y = y - vel
if keys[pygame.K_DOWN] and y < 500 - height - vel:
y = y + vel
if keys[pygame.K_SPACE]:
isJump = True
else:
if jumpCount >= -10:
neg = 1
if jumpCount < 0:
neg = -1
y = y - (jumpCount ** 2) * 0.5 * neg
jumpCount = jumpCount - 1
else:
isJump = False
jumpCount = 10
win.fill((0, 0, 0))
pygame.draw.rect(win, colour, (x, y, width, height))
pygame.display.update()
pygame.quit()
