我试图使用Pygame的Clock.tick,但它并不存在。我很正面Pygame为Python 3提供了它,即使我使用dir(pygame.time.Clock),它仍然没有。我不确定我是否做了一些严重的错误,或者Pygame没有为Python 3做过。

这是我的代码:

import pygame, random, sys
from pygame.locals import *

class Pong_Ball(object):
    def __init__(self, screen, screen_height, screen_width):
        self.screen = screen
        self.screen_height = screen_height
        self.screen_width = screen_width

    def update(self):
        #pong ball's properties
        self.ball_color = 191,191,191
        self.pos_x = 100
        self.pos_y = 100
        self.vel_x = 1
        self.vel_y = 1

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

            #clear the screen
            self.screen.fill((0,50,100))

            #move the pong ball
            self.pos_x += self.vel_x
            self.pos_y += self.vel_y

            #keep the ball on the screen
            if self.pos_x > self.screen_width or self.pos_x < 0:
                self.vel_x = -self.vel_x
            if self.pos_y > self.screen_height or self.pos_y < 0:
                self.vel_y = -self.vel_y

            #draw the pong ball
            self.position = self.pos_x, self.pos_y
            pygame.draw.circle(self.screen, self.ball_color, self.position, 10)

            #update the display
            pygame.time.Clock.tick(60)
            pygame.display.update()

def main():
    pygame.init()
    screen = pygame.display.set_mode((800,600))
    ball = Pong_Ball(screen, 600, 800)
    ball.update()

main()

阿。 documentation虽然完全标准,但可能有点令人困惑。尽管他们写Clock.tick,但他们并不是说这是一个静态的方法。你在一个实例上调用它:

>>> import pygame
>>> clock = pygame.time.Clock()
>>> clock
<Clock(fps=0.00)>
>>> clock.tick
<built-in method tick of Clock object at 0xb402b408>
>>> clock.tick()
14487
>>> clock.tick()
836

确认它的行为:

>>> import time
>>> for i in range(5):
...     print clock.tick()
...     time.sleep(0.17)
...

pygame.time.Clock.tick(60)替换为pygame.time.Clock().tick(60)
