Question

所以我一直在播放器的侧面进行操作，但确实遇到了一个问题，那就是当播放器在尝试移动时跳动时，播放器不会响应我按下的键。这些键仅在播放器开始掉落时响应。

在发生这种情况时，跳到其他平台非常困难，这是在我让播放器碰到平台侧面之后立即开始发生的。

我不确定它发生在哪里，但这是我让播放器跳转的地方

        # Jumping
        if collide:
            if keys[pygame.K_SPACE]:
                playerman.isJump = True
                py -= playerman.speed
            playerman.fall = 0

跳跃时循环忽略X的运动。

更改此：

if not playerman.isJump and player_rect.collidelist(platform_rect_list) < 0:
        playerman.x = px

为此：

# if not playerman.isJump and 
if player_rect.collidelist(platform_rect_list) < 0:
    playerman.x = px

玩家跳跃时玩家键不会响应
