Stoppers

Stoppers (//) are a DDRace-specific 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.

Collisions and Hitboxes

Stoppers are not collision-checked through interpolation. Thus, if you pass by a stopper's hitbox between two ticks, your position will not be stopped 'between' your two tick locations.

This leads to a couple effects:

• Your first tick inside a stopper will be the position you're stopped at.
• Stoppers can be easily skipped with Ninja.

Hitboxes

• 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.
