Stoppers ({{Tile|entities|60}}/{{Tile|entities|61}}/{{Tile|entities|62}}) are a DDRace-specific [[Special:MyLanguage/tiles|tile]] that prevent tees but not projectiles from passing through. There are three types of stoppers: each halting movement in either one, two, our four directions.
Stoppers are not collision-checked through interpolation. Thus, if you pass by a stopper's hitbox between two [[Special:MyLanguage/Ticks|ticks]], your position will not be stopped 'between' your two [[Special:MyLanguage/Ticks|tick]] locations.
* 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 <code>34</code> units upwards from the center but <code>16</code> 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 <code>34</code> units upwards and downwards from the center but <code>16</code> units left and right from the center.
** 4-way stoppers will prevent inwards motion starting a distance <code>34</code> units in all directions from the center. Keep in mind that the hitbox is "+" shaped rather than square shaped.
