阻滞器

阻滞器(//)是DDRace特有的tile，它在阻止玩家通过的同时允许其他实体通过。阻滞器有三种类型：分别从单向、双向或者四向阻滞玩家的移动。

关于碰撞和碰撞箱

阻滞器不会采用插值的碰撞检测。正因如此，如果你通过阻滞器的碰撞箱的“时刻”处在两个ticks之间，你将会直接穿过去而不会滞留在阻滞器中。

这个特性带来了下面这些影响：

• 如果你运动前一tick就处在阻滞器中会被滞留。
• 使用Ninja可以轻易地越过阻滞器。

碰撞箱

• Be aware - since stoppers are easily skippable, these hitboxes don't mean much due to the fact that one can easily skip several units through a stopper with speed.
  • 1-way stoppers (assumed to be pointing upwards) will prevent further downwards motion starting a distance 34 units upwards from the center but 16 units leftwards, rightwards, and downwards from the center.
  • 2-way stoppers (assumed to be pointing up and down) will prevent inwards motion starting a distance 34 units upwards and downwards from the center but 16 units left and right from the center.
  • 4-way stoppers will prevent inwards motion starting a distance 34 units in all directions from the center. Keep in mind that the hitbox is "+" shaped rather than square shaped.
