为什么我的游戏的角色运动无法正常工作

如何解决为什么我的游戏的角色运动无法正常工作

我的角色移动有问题，我完全不知道为什么 当我运行它时，它向前移动，像虫子一样向后移动 我改变了速度和帧率无济于事，并且害怕触摸代码，因为当背景可见时我才让它工作

import pygame
import os

WIDTH,HEIGHT = 1920,1080
WIN = pygame.display.set_mode((WIDTH,HEIGHT))
pygame.display.set_caption("Gaem")
WHITE = (255,255,255)
FPS = 60
Vel = 5
CHaraCTER = pygame.image.load('MAN.png')
def draw_window(CHaraCTERM):
    WIN.fill((WHITE))
    WIN.blit(CHaraCTER,(CHaraCTERM.x,CHaraCTERM.y))
    
    pygame.display.update()

def main():
    CHaraCTERM = pygame.Rect(100,300,850,450)

    clock = pygame.time.Clock()
    
    run = True
    while run:
        clock.tick(FPS)
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                run = False


##########CHaraCTER MOVMENT####################
        draw_window(CHaraCTERM)
        keys_pressed = pygame.key.get_pressed()
        if keys_pressed[pygame.K_a]: #Left
            CHaraCTERM.x -= Vel


        draw_window(CHaraCTERM)
        keys_pressed = pygame.key.get_pressed()
        if keys_pressed[pygame.K_d]: #Right
            CHaraCTERM.x += Vel


        draw_window(CHaraCTERM)
        keys_pressed = pygame.key.get_pressed()
        if keys_pressed[pygame.K_w]: #Up
            CHaraCTERM.y -= Vel


        draw_window(CHaraCTERM)
        keys_pressed = pygame.key.get_pressed()
        if keys_pressed[pygame.K_s]: #Down
            CHaraCTERM.y += Vel

        draw_window(CHaraCTERM)
    pygame.quit()

if __name__ == "__main__":
    main()

谢谢 Zatando1

解决方法

调用 pygame.key.get_pressed() 和 draw_window() 一次就足够了：

def main():
    CHARACTERM = pygame.Rect(100,300,850,450)
    clock = pygame.time.Clock()
    
    run = True
    while run:
        clock.tick(FPS)
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                run = False
        keys_pressed = pygame.key.get_pressed()
        if keys_pressed[pygame.K_a]: #Left
            CHARACTERM.x -= Vel
        if keys_pressed[pygame.K_d]: #Right
            CHARACTERM.x += Vel
        if keys_pressed[pygame.K_w]: #Up
            CHARACTERM.y -= Vel
        if keys_pressed[pygame.K_s]: #Down
            CHARACTERM.y += Vel

        draw_window(CHARACTERM)
    pygame.quit()

如果多次调用 draw_window()，pygame.display.update() 将在每一帧中执行多次。在应用程序循环结束时更新显示就足够了。多次调用 pygame.display.update() 或 pygame.display.flip() 会导致闪烁。
