Коллизии
Коллизия происходит между тайлами, игроками и снарядами в мире.
Представьте, что каждая тайл состоит из матрицы более мелких субквадратов. Каждый из этих субквадратов представляет собой единственную, уникальную позицию, которую может занять игрок в любой момент времени, причем этот один субквадрат представляет собой возможный центр позиции игрока.
- Один тайл в мире имеет ширину и высоту 32 единицы. (Это означает, что игрок может занять в общей сложности 1024 уникальные позиции внутри одного тайла).

Different tiles have different collision hitboxes. In respect to the center position of a tee:
- Standard DDRace tiles (the vast majority of tiles unique to DDRace modes, such as freeze and tele) have a square hitbox of
32x32
units. - Kill tiles have a square hitbox of
50x50
units. - Solid tiles (unhookable, hookable, hookthrough) have a square hitbox of
60x60
units. - Freeze lasers are complicated. Assuming a freeze laser pointing upwards with the source entity at the bottom (which creates a "top" freeze laser at the uppermost tile, 2 full tiles of vertical freeze laser in the middle, and a bottom "source" laser tile.):
- From the side, they will freeze a distance of
28
units left and right from the center. - From the top, they have a hitbox radius of units
27
units upwards from the center. - From the side, they will freeze a distance of
28
units downwards from the center.
- From the side, they will freeze a distance of
- Stoppers are a little more complicated. 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 but16
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 but16
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. - Tees can dash through stoppers with Ninja
- 1-way stoppers (assumed to be pointing upwards) will prevent further downwards motion starting a distance
- Doors are handled internally the same as stoppers, so are skippable the same way with speed.

Tees collide with other tees as circles with diameter of 28 units, although tees already interact if they come as close as 35 units. Tees gain speed in the opposite direction of the interaction point, and the amount of speed gained depends on the distance between the two tees during the collision (the farther away the less speed gained) as well as the angle at which they bump into each other (when moving directly into the direction of the other tee, the most speed is added). Strong and weak also play a role, with strong tees bumping a bit more than tees with weak.
