Box Changes:
> Collision box replaced with a collision cylinder with a diameter of 112% of the length of the horizontal sides of the according box, vertical sides remain unchanged
> Melee collision box replaced with a bounding cylinder with a diameter of 112% of the current box’s width
> Projectile collision boxes replaced with a bounding sphere with a diameter of 112.8% of the current box’s width
Reasoning:
TF2 has projectile, melee and player collision boxes, and they are distinct from hitscan hitboxes in that they're a literal single box. In addition to that, their rotation is locked and independent of anything a player can do. This leads to huge, effectively random variances in cross section area, making shots miss when they would otherwise hit, and vice versa. This also causes such variance between players and players and surfaces, as it affects wheter they'll slide against or get stopped by said player or thing. Our changes make these interactions and cross sections consistent and are adjusted to retain the current average cross section areas.
