pygame中对象的速度？

Question

我正在编写一个简单的pygame程序,它只包含在屏幕上移动一个框.盒子移动得非常快,我想知道如何控制速度.在我的代码中,更新的位置移动1而不是更小,因为如果数字不是整数,则会使事情变得更复杂.

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

pygame.init()
mainClock = pygame.time.Clock()

WINDOWWIDTH = 400
WINDOWHEIGHT = 400
windowSurface = pygame.display.set_mode((WINDOWWIDTH, WINDOWHEIGHT), 0, 32)
pygame.display.set_caption("Box")

BLACK = (0, 0, 0)
RED = (255, 0, 0)
WHITE = (255, 255, 255)
size1 = 20
size2 = 2
#character = pygame.Rect(30, 30, 20, 30)
player = pygame.Surface((40,40))




pos1 = 100
pos2 = 100


MOVESPEED = 6

x = 1

while True:
    if pos1 == WINDOWWIDTH - 40 and pos1 > 0:
        pos1 -= 1
        x += 1
    elif pos1 < WINDOWWIDTH - 40 and x == 1:
        pos1 += 1
    elif x ==2:
        pos1 -= 1


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

                pos1 -= 5
            if event.key == K_RIGHT:
                pos1 += 4


    windowSurface.fill(WHITE)

    #screen.blit(character)



    windowSurface.blit(player, (pos1, pos2))
    pygame.display.update()

你应该在你的"while True:"循环中放入以下代码:

clock.tick([insert fps here])

并把它放在循环之前的某个地方:

clock=pygame.time.Clock()

这将不允许循环运行的次数超过您每秒输入的次数,并且希望减慢多维数据集的速度.
