pygame.display.update() 在循环中不起作用

Question

我正在开发一个简单的游戏。当我循环绘制某些东西时，它绘制它的时间不到一秒钟。这是我的代码：

import pygame, sys
from pygame.locals import*

pygame.init()
FPS = 30
fpsClock = pygame.time.Clock()

DISPLAYSURF = pygame.display.set_mode((1000, 750))
BASICFONT = pygame.font.Font('freesansbold.ttf', 18)
pygame.display.set_caption('Game')

while True:
        for event in pygame.event.get():
            if event.type == pygame.MOUSEMOTION:
                "do something"

            else:
                posx, posy = pygame.mouse.get_pos()
                if event.type == pygame.MOUSEBUTTONUP:
                    if posx == 500 and posy == 500:
                        DISPLAYSURF.fill((40, 40, 40))
                        pygame.draw.rect(DISPLAYSURF, (40, 40, 40), (posx, posy, 50, 20))

        pygame.display.update()

我做错了什么？

Answer 1

仅当鼠标位于 500,500 并且触发事件 MOUSEBUTTONUP 时才更新显示。我会将其更改为：

import pygame, sys
from pygame.locals import*

pygame.init()
FPS = 30
fpsClock = pygame.time.Clock()

DISPLAYSURF = pygame.display.set_mode((1000, 750))
BASICFONT = pygame.font.Font('freesansbold.ttf', 18)
pygame.display.set_caption('Game')

while True:
    for event in pygame.event.get():
        if event.type == pygame.MOUSEMOTION:
            "do something"

        else:
            posx, posy = pygame.mouse.get_pos()
            if event.type == pygame.MOUSEBUTTONUP:
                if posx == 500 and posy == 500:
                    DISPLAYSURF.fill((40, 40, 40))
                    pygame.draw.rect(DISPLAYSURF, (40, 40, 40), (posx, posy, 50, 20))

    pygame.display.update()

pygame.display.update() 在循环中不起作用

pygame.display.update() doesn't work in a loop

python

pygame
