Question

好，所以我一直在尝试找出如何进行设置，但无法使其正常工作。如果您熟悉的话，我正在尝试获得与游戏Frogger中的移动日志类似的功能。到目前为止，我所进行的碰撞检测仅适用于一个pygame.sprite.Group()

running = True

onLogRight = False
groundSpd = 48
while running:

    clock.tick(FPS)

    hitsleft = pygame.sprite.spritecollide(player, movingobj_l, False, pygame.sprite.collide_rect)
    for hit in hitsleft:
        player.speedx = pos_objspeed
        player.speedy = 0
        onLogLeft = True
    if len(hitsleft) == 0:

        player.speedy = 0


    for event in pygame.event.get():
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                player.speedx = -groundSpd

            if event.key == pygame.K_DOWN:
                player.speedy = groundSpd

        if event.type == pygame.KEYUP and onLogLeft == False and onLogRight == False:
            if event.key == pygame.K_LEFT:
                player.speedx = 0
            if event.key == pygame.K_RIGHT:
                player.speedx = 0
            if event.key == pygame.K_UP:
                player.speedy = 0
            if event.key == pygame.K_DOWN:
                player.speedy = 0

    if onLogLeft == False and onLogRight == False and player.rect.bottom <= 384:
        running = False

    player.rect.x += player.speedx
    player.rect.y += player.speedy

    if event.type == pygame.QUIT:
        running = False



    #player.rect.x += player.speedx
    #player.rect.y += player.speedy

    all_sprites.update()
    screen.fill(BLACK)
    all_sprites.draw(screen)
    pygame.display.flip()



pygame.quit()
quit()

好吧，在我的代码中

hitsright = pygame.sprite.spritecollide(player, movingobj_r, False, pygame.sprite.collide_rect)

检查碰撞并更新玩家的速度，但

hitsleft = pygame.sprite.spritecollide(player, movingobj_l, False, pygame.sprite.collide_rect)

没有做同样的事情。

如果有人有任何想法，为什么我会感到困惑。另外，我该如何解决这两种问题呢？

Answer 1

左右代码的行为有所不同，因为如果检测到与.right{ width: 30%; } .left{ ... //width must be auto }的冲突，则会设置var ul = document.getElementById("homePage_content-ul"); var li = ul.getElementsByTagName("li"); var numItems = li.length; var css = document.createElement("style"); css.type = "text/css"; css.innerHTML = "ul#homePage_content-ul { column-count: " + Math.round(numItems/2) + "; column-gap: 0; }"; document.body.appendChild(css);：

hitsleft

但是如果与player.speedx发生冲突，就不会与for hit in hitsleft: player.speedx = pos_objspeed发生冲突，并且hitsleft会立即重置：

hitsright

您必须根据两个条件（例如，在player.speedx-if len(hitsright) == 0: onLogRight = False player.speedx = 0-player.speedx语句中设置if：

elif
