矩形不移动 Pygame

Question

我正在尝试在 pygame 中制作乒乓球游戏。 所以我需要制作一个由玩家控制的矩形。 为此，我定义了一些变量。

变量

player = pygame.Rect(s_width - 10, s_height/2 - 35, 5, 70)
player_speed = 0

在循环

player.y += player_speed

for event in pygame.event.get():
    if event.type == pygame.QUIT:
        running = False
    if event.type == pygame.KEYDOWN:
        if pygame.key == pygame.K_DOWN:
            player_speed += 5
        if pygame.key == pygame.K_UP:
            player_speed -= 5
    if event.type == pygame.KEYUP:
        if pygame.key == pygame.K_DOWN:
            player_speed = 0
        if pygame.key == pygame.K_UP:
            player_speed = 0

您的代码中只有一个问题； 你不检查

if pygame.key == pygame.K_...

您需要将pygame.key替换为event.key ：

if event.key == pygame.K_...

import pygame
pygame.init()

s_width, s_height = 600, 600
wn = pygame.display.set_mode((s_width, s_height))

player = pygame.Rect(s_width - 10, s_height/2 - 35, 5, 70)
player_speed = 0

clock = pygame.time.Clock()

while True:
    clock.tick(60)
    player.y += player_speed
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_DOWN:
                player_speed += 5
                print(player_speed)
            if event.key == pygame.K_UP:
                player_speed -= 5
        if event.type == pygame.KEYUP:
            if event.key == pygame.K_DOWN:
                player_speed = 0
            if event.key == pygame.K_UP:
                player_speed = 0
    wn.fill((0, 0, 0))
    pygame.draw.rect(wn, (255, 0, 0), player)
    pygame.display.update()

Output：
