如何解决一段时间后，Pygame 徽标又变回来了

我是 pygame 的菜鸟，我遇到了问题。一段时间后，Pygame 徽标会发生变化。我有两个图像。请帮忙！第一张图片是窗口应该是什么样子的，第二张图片是我 20 秒后的窗口。我该怎么办？我从来没有遇到过这个问题，我尝试了很多东西，但我做不到。

import pygame 
import random

# initialize idk pygame.init()

# size Width = 800 Height = 600 white = (255,255,255) icon = pygame.image.load('sunflower.png') player_img =
pygame.image.load('cat.png') enemy1_img = pygame.image.load('dog.png')
FPS = 120 Vel = 5

# enemy random coordinates enemy1_X = random.randint(64,736) enemy1_Y = random.randint(50,150)


# screen def screen_f(p_rect,e_rect):
screen = pygame.display.set_mode((800,600))
pygame.display.set_caption('dog destroyer')
icon = pygame.image.load('sunflower.png')
pygame.display.set_icon(icon)
backgroud = pygame.image.load('backg.png')
screen.blit(backgroud,(0,0))
screen.blit(player_img,(p_rect))
screen.blit(enemy1_img,(e_rect))


# player def player_movement(key_pressed,p_rect):
if key_pressed[pygame.K_RIGHT]:
    p_rect.x += Vel
if key_pressed[pygame.K_LEFT]:
    p_rect.x -= Vel
if key_pressed[pygame.K_UP]:
    p_rect.y -= Vel
if key_pressed[pygame.K_DOWN]:
    p_rect.y += Vel


def borders(p_rect):
    if p_rect.x < 0:
        p_rect.x = 0
    elif p_rect.x > 735:
        p_rect.x = 735
    elif p_rect.y < 0:
        p_rect.y = 0
    elif p_rect.y > 535:
        p_rect.y = 535


# main def main():
Vel_e = 4  # enemy  velocity
player_rect = pygame.Rect(368,500,64,64)
enemy_rect = pygame.Rect(enemy1_X,enemy1_Y,64)

clock = pygame.time.Clock()
run = True
while run:
    clock.tick(FPS)
    key_pressed = pygame.key.get_pressed()

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

    enemy_rect.x += Vel_e
    if enemy_rect.x >= 736:
        Vel_e = -4
        enemy_rect.y += 50
    if enemy_rect.x < 0:
        Vel_e = 4
        enemy_rect.y += 50

    borders(player_rect)
    player_movement(key_pressed,player_rect)
    screen_f(player_rect,enemy_rect)
    pygame.display.update()


if __name__ == "__main__":
    main()

Before

After 20 seconds

解决方法

您的代码不清晰，但我想我知道如何修复它。

您通常希望在文件的开头设置屏幕和其他重要内容，而不是在必须调用的 def 中。

试试这样：

import pygame

pygame.init()

width = ...
height = ...
fps = ...
#set any colors

#load all you pictures

screen = pygame.display.set_mode((width,height))
# you would also want to set your caption and icon here so:
pygame.display.set_caption('your caption')
pygame.display.set_icon(icon)

#all your defs

#and when its all set you go to a main loop.

#(at the bottom of your file)
main()
# and quit for if the user quits and run gets set to False
pygame.quit()
quit()
