pygame 表面对象不可订阅

Question

这是我的代码

import pygame, sys
from pygame.locals import *

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

pygame.display.set_caption("hello mom and dad")

player_image = pygame.image.load('player.png')
player_location = [355,245]

move_right = False
move_left = False

player_y_momentum = 0

while True: #codes written outside of this loop wont run in the window or get executed
screen.fill((146, 244, 255))

screen.blit(player_image, [155, 245])#player model

if player_location[1] > screen[1] - player_image.get_height():
    player_y_momentum = -player_y_momentum
else:
    player_location[1] += player_y_momentum

if move_right == True:
    player_location[0] += 1
if move_left == True:
    player_location[0] -= 1


for event in pygame.event.get():
    if event.type == pygame.QUIT:
        pygame.quit()
        sys.exit()
    if event.type == KEYDOWN:
        if event.key == K_RIGHT:
            move_right = True
        if event.key == K_LEFT:
            move_left = True
    if event.type == KEYUP:
        if event.key == K_RIGHT:
            move_right = False
        if event.key == K_LEFT:
            move_left = False
pygame.display.update() #put stuff above this code to put it in the game

如果 player_location[1] > screen[1] - player_image.get_height():

，它一直在第 22 行说 'pygame.Surface' 对象不可订阅

我正在学习 pygame 上的教程，它教我有关动量的知识，它向我发送了错误消息，我尝试用谷歌搜索它，它总是说“记住丢失的逗号”，它显示了 screen.blit我的代码部分应该是名为“player_location”的变量，我是 python 和 pygame 的新手，我不知道怎么了

您正在尝试访问 screen[1]，但 screen 的类型为 pygame.Surface。要获得 screen 的高度，请改用 screen.get_height()：

if player_location[1] > screen.get_height() - player_image.get_height():
