Question

因此，由于某种原因，我的对象/规则不会停留在我告诉它的同一位置，每次移动时，它都会朝与我相反的方向移动，并且每次与平台相撞并按a或某物时，它将向右移动，但是如果我在按d时与平台碰撞，它将向左移动。 https://gyazo.com/b3adcbe08a79760e1cd0ded940ee2373我希望它留在同一地点，但不要留在该地点。

我编写了这段代码，但仅适用于我的平台

let { parameter } = useParams()

我的完整代码

    if keys[pygame.K_d]:
        for Platform in platforms:
            Platform.x -= playerman.speed
        for Rule in rules:
            Rule.x -= playerman.speed
        
 

    if keys[pygame.K_a]:
        for Platform in platforms:
            Platform.x += playerman.speed
        for Rule in rules:
            Rule.x += playerman.speed

您必须像移动Rule对象一样移动Platform对象。如果玩家撞到平台，则必须像对Rule对象那样“撤消” Platform对象的移动：

while run:
    # [...]

    # lets player move
    keys = pygame.key.get_pressed()
    px, py = playerman.x, playerman.y

    platform_rect_list = [p.rect for p in platforms]
    player_rect = playerman.get_rect()
    player_rect.topleft = (px, py)

    playerman.y = py
    if player_rect.collidelist(platform_rect_list) < 0:
        playerman.x = px

    move_right = keys[pygame.K_d]
    move_left = keys[pygame.K_a]
    if move_right: 
        for Platform in platforms:
            Platform.x -= playerman.speed
        for Rule in rules:
            Rule.x -= playerman.speed     # <---
    if move_left:
        for Platform in platforms:
            Platform.x += playerman.speed
        for Rule in rules:
            Rule.x += playerman.speed     # <---

    platform_rect_list = [p.get_rect() for p in platforms] # get_rect()
    player_rect = playerman.get_rect()
    player_rect.topleft = (px, py)

    playerman.y = py
    cI = player_rect.collidelist(platform_rect_list)
    if cI >= 0:
        # undo movement of platforms dependent on the direction and intersection distance
        dx = 0
        if move_right: 
            dx = platform_rect_list[cI].left - player_rect.right
        if move_left:
            dx = platform_rect_list[cI].right - player_rect.left
        for Platform in platforms:
            Platform.x -= dx
            Platform.get_rect() # update rectangle
        for Rule in rules:
            Rule.x -= dx             # <---

为什么我的物体不停留在我告诉它停留的同一地点
