How can I make a sprite move when key is held down（6个答案）
11小时前关门了。
这里我已经写了playerX_change的代码（它是第一次定义为0的值），当按下任何键（如左或右）时，它应该通过改变x的值来响应，但它没有
我试图纠正索引，也试图为它创建新的变量，请尝试其他东西，并提出建议的变化
这是密码

import pygame

pygame.init()
screen = pygame.display.set_mode((800, 600))

pygame.display.set_caption("It's a game -_-")
icon = pygame.image.load('ufo.png')
pygame.display.set_icon(icon)

running: bool = True

playerimg = pygame.image.load('spaceship3.png')
playerX = 370
playerY = 480

def player(x, y):
    screen.blit(playerimg, (x, y))

while running:
    screen.fill((22, 11, 222))
    playerX_change = 0
    player(playerX, playerY)
    pygame.display.update()
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
    # it shows basically that every key pressed inside the window gets stored in pygame.event
    if event.type == pygame.KEYDOWN:
        if event.key == pygame.K_LEFT:
            playerX_change = -0.1
        if event.key == pygame.K_RIGHT:
            playerX_change =0.1
    if event.type == pygame.KEYUP:
        if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:
            playerX_change = 0
