Collisions
Dans le world, les Collisions arrivent entre les tuiles, les projectiles et les tees.
Imaginez que chaque tuile soit composée d'une matrice de sous-carrés plus petits. Chacun de ces sous-carrés représente une position unique qu'un tee peut occuper à tout moment, avec un sous-carré représentant un centre possible de la position d'un tee.
Collision des tuiles
Les différentes tuiles ont hitbox de collision différentes. Par rapport à la position centrale d'un tee :
- Les tuiles DDRace standard (la grande majorité des tuiles uniques aux modes DDRace, comme le freeze et les téléporteurs) ont une hitbox carrée de
32x32
unités. - 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.
Tee Collision
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.
