Question

我在pygame中尝试增量时间，但是当我开始游戏时，增量时间在前两个游戏循环中总是非常高。这是我目前的代码：

    app.use(session({
  store: new RedisStore({
    client: redis_client,
    ttl: 28800 // 8 hours
  }),
  secret: config.redis_session_secret,
  resave: false,
  saveUninitialized: false,
  cookie: {
    path: '/',
    httpOnly: true,
    secure: false,
    maxAge: 30 * 60 * 1000 //mins * seconds * milliseconds. session cookie will expire every 30 mins 
  }, 
  rolling: true
}));

它给了我这个输出：

import sys

import pygame

class Player(pygame.sprite.Sprite):
    def __init__(self):
        pygame.sprite.Sprite.__init__(self)

        self.image = pygame.Surface([32, 32])
        self.image.fill((255, 128, 0))

        self.rect = self.image.get_rect()
        self.rect.x = 20
        self.rect.y = 20

    def update(self, dt):
        self.rect.x += dt / 10

    def draw(self, screen):
        screen.blit(self.image, [self.rect.x, self.rect.y])

class GameState():
    def __init__(self):
        self.player = Player()

    def update(self, dt):
        self.player.update(dt)

    def draw(self, screen):
        self.player.draw(screen)

class Control():
    def __init__(self):
        self.state = GameState()

def main():
    pygame.init()

    fps = 60
    fpsClock = pygame.time.Clock()

    width, height = 640, 480
    screen = pygame.display.set_mode((width, height))

    control = Control()

    dt = fps

    while True:
        screen.fill((0, 0, 0))

        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                sys.exit()

        control.state.update(dt)

        control.state.draw(screen)

        pygame.display.flip()
        dt = fpsClock.tick(fps)

if __name__ == '__main__':
    main()

我尝试过更改dt的初始值，但这没有任何作用。我认为这与我的游戏初始化时间过长有关。如果是这样，我该如何解决这个问题？

尝试在第一个循环开始之前将时钟的创建移动到右边。否则，您看到的第一个抖动是初始化代码的测量。

pygame.init()

fps = 60

width, height = 640, 480
screen = pygame.display.set_mode((width, height))

control = Control()

dt = fps
# start recording clock from here
fpsClock = pygame.time.Clock()
while True:
    screen.fill((0, 0, 0))

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()

    control.state.update(dt)

    control.state.draw(screen)

    pygame.display.flip()
    dt = fpsClock.tick(fps)

开始时的Pygame delta时间震动
