我试图解决pygame上这种不流畅和断断续续的动画和动作，我一直在尝试一切，但没有任何效果

这是动画的视频https://www.youtube.com/watch?v=uhPdN3v8vg0

其他pygame代码的行为不是这样的，只有这个特定的代码，所以我很确定这不是硬件问题

import sys
import time
import pygame
import os
from pygame import mixer
pygame.init()
pygame.mixer.init()
width,height=(900,500)
border= pygame.Rect(0,0,6,height)
WIN=pygame.display.set_mode((width,height))
bg= pygame.image.load(os.path.join('','pixel_bg.jpg'))
bg=pygame.transform.scale(bg,(width,height))
person1=pygame.image.load(os.path.join('','mario.png'))
p1_width, p1_height = (50,60)
person1=pygame.transform.scale(person1,(p1_width,p1_height))
black=(0,0,0)
p1_rect = pygame.Rect(50,340,p1_width,p1_height)
pygame.display.set_caption("rpg game")
Velocity= 4
jump_height = 50
FPS = 60
mixer.music.load("adventurebeat.mp3")
mixer.music.play(-1)
def draw():
WIN.blit(bg, (0, 0))
WIN.blit(person1, (p1_rect.x,p1_rect.y))
pygame.display.update()
def p1_movement(keys_pressed, p1_rect):
if keys_pressed[pygame.K_a] and p1_rect.x - Velocity > border.x + border.width:  # left
p1_rect.x -= Velocity
if keys_pressed[pygame.K_d] and p1_rect.x + Velocity + p1_rect.width < width:  # right
p1_rect.x += Velocity
if keys_pressed[pygame.K_w] and p1_rect.y - Velocity > 0:  # up
p1_rect.y -= Velocity
if keys_pressed[pygame.K_SPACE] and p1_rect.y - Velocity > 0:  # up
p1_rect.y -= jump_height
if keys_pressed[pygame.K_s] and p1_rect.y + Velocity + p1_rect.height < height:  # down
p1_rect.y += Velocity
def main():
clock = pygame.time.Clock()
run = True
while run:
clock.tick_busy_loop(FPS)
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
pygame.quit()
sys.exit()
draw()
keys_pressed = pygame.key.get_pressed()
p1_movement(keys_pressed,p1_rect)
main()

我试过将clock.tick_businy_lop((更改为clock.tick((，但仍然不起作用：/

您需要draw应用程序循环中的对象，而不是事件循环：

def main():
clock = pygame.time.Clock()
run = True
while run:
clock.tick_busy_loop(FPS)
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
pygame.quit()
sys.exit()

# draw()   <--- DELETE

keys_pressed = pygame.key.get_pressed()
p1_movement(keys_pressed,p1_rect)
draw()       # <--- INSERT

应用程序循环在每一帧中执行，但事件循环仅在事件发生时执行。
