1]在我的代码中，问题是我的玩家类下面的平台已连接，并且当玩家移动时平台也已连接，如果是，则玩家一直在平台上移动。有人可以告诉我该如何解决吗？如果您想在哪里查找所有代码以及它将在哪里查找，那么这里就是所有代码，因为我不知道是什么原因导致了我的代码出现问题。

from pygame.locals import *
#The platform class is the problem I'm having
class Platform:
def __init__(self, size, x, y, length, color, velocity):
self.length = length
self.size = size
self.x = x
self.y = y
self.color = color
self.velocity = velocity
self.xVelocity = 0

# This is def draw function is showing that how I want my Platform to look like
def do(self):
self.draw()
2）当我的播放器到达屏幕的“末端”时，它停止了，但是我想使其成为滚动屏幕，什么也没有发生，因此当播放器移动并自行滚动时，就没有游戏了。有人告诉我如何解决第二个问题后，如果背景超过播放器，我希望背景杀死播放器。

3）最后，对不起缺少好的代码以及在哪里查看代码感到抱歉，因为我不知道是什么原因导致了我的代码出现问题，因此我不得不将所有内容都排除掉。
我编辑了一些代码，以解决您遇到的问题，我确实更改了图像，但没有，但是我通过使玩家不断跌倒并检查玩家是否与平台相撞来固定跳跃和站立在平台上。我还添加了滚动背景。删除了我的评论中提到的不必要的代码。更改了玩家移动以从那里跳。将平台的大小更改为列表，使其具有宽度和高度。由于平台不移动，也摆脱了速度。
