python - 我正在尝试在屏幕底部创建一个平台,但它一直给我一个错误
问题描述
我在编写代码时遇到问题,这是它显示的错误
platforms_list.append[pl,Platform([200,20], 100, 450, White), Platform([200,20], 400, 250, White)] TypeError: 'builtin_function_or_method' object is not subscriptable
我不明白可下标是什么意思。我有一个圆形玩家可以跳跃移动并且可以四处走动但是因为没有底部平台而从他的平台上掉了下来而且我不知道如何制作它

#check for x button clicked

#update the player

for platform in platforms_list:
platform.x -= 1
if background_scroll == w:
background_scroll = 0
#same but for the left
if p.x - p.size <= 0:
p.x = 0 + p.size
background_scroll -= 1
for platform in platforms_list:
platform.x += 1
if background_scroll == 0:
background_scroll = w
#update screen
pygame.display.update()
Clock.tick(FPS)
DS.fill(Black)
platforms_list.append[pl,Platform([200,20], 100, 450, White), Platform([200,20], 400, 250, White)]
这是我添加的代码,但它一直给我代码
解决方案
I think append needs to be .append()
not []
.
Try this:
platforms_list.append(pl,Platform([200,20], 100, 450, White), Platform([200,20], 400, 250, White))
