为什么当我的播放器向右或向左移动时我的平台在移动

Question

1) 在我的代码中，问题是我的玩家类下面的平台是连接的，当玩家移动时，平台也会连接，如果是这样，玩家会一直在平台上移动。有人可以告诉我如何解决吗？如果您想知道在哪里查找所有代码以及它将在哪里查找所有代码，因为我不知道是什么导致了我的代码中的问题。

import math
import os
import sys
# It is importing everything
import pygame
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 what the platform class has and what it does
    def draw(self):
        display = pygame.display.get_surface()
        pygame.draw.rect(display, self.color, (int(self.x) - 80, int(self.y) + 225, int(self.x), int(self.y) - 45))

    # This is def draw function is showing that how I want my Platform to look like
    def do(self):
        self.draw()

2) 当我的玩家到达屏幕的“末端”时它会停止，但我想让它成为一个滚动屏幕并且没有任何反应，然后当玩家移动并自行滚动时就没有游戏了。在有人告诉我如何解决我的第二个问题之后，如果背景越过玩家，我希望背景杀死玩家。

# The def do function is running def draw function

3) 最后很抱歉缺少好的代码以及在哪里查看代码，因为我不知道是什么导致了我的代码中的问题，所以我不得不把它全部放出来。

Answer 1

我稍微编辑了您的代码，以便解决您遇到的问题，我确实更改了图像，因为我没有它，但我通过让玩家不断跌倒并检查玩家是否与平台。我还添加了滚动背景。摆脱了我的 cmets 中提到的不必要的代码。改变了玩家从那里跳跃的动作。将平台中的大小更改为列表，使其具有宽度和高度。由于平台没有移动，因此也摆脱了速度。
