Hitboxes

Hitboxes are the main structure for how attacks are executed in the Super Smash Flash series, representing areas in which an attack can hit an opponent. For example, when a character utilizes a slashing attack, the hitbox is focused around the area where the weapon slashes. Several types of attacks with longer range contain hitboxes that extends farther.

They are typically hidden, but can be made visible by modifying the game's files.

Disjointed hitboxes
Disjointed hitboxes are attackboxes that are not attached to the normal hitboxes of characters. These types of hitboxes can hit projectiles and other attacks without risking damage to the player. These hitboxes tend to be found on weapons, such as weapons. Some of them are long, giving more range to the character's attacks. Several characters who possess attacks that contain unique properties or outlarged range, such as, and , or characters with projectile-based playstyles, such as ,  and.

Interpolation
Interpolation is the action of giving some parts of frame-hitboxes when they would not typically possess them. This can make the colliding hitboxes more accurate. It can be used in the blur of swords or in parts beyond a character's limbs.

Separation
Separation, also referred as Detachment or Disconnection, is the most unique action of hurtboxes and hitboxes which can disattach from their normal placements of the owner's.

Seperation, by its true appearance, is arguably in a similar fashion to disjointed hitboxes, but the only primary difference is that they are separated from each other. Unlike disjointed hitboxes, however, seperated hurtboxes (or hitboxes) are divided into many parts; depending on the type of attack which represent separated hitboxes.

For example, 's hurtboxes are attached on his limbs, not his enitre body (including his phantom limbs located at his neck, arms, and legs), so any type of attacks that goes through his invisible arms and touches his phantom limbs will not cause any knockback or damage to Rayman; possibly possessing knockback resistance, similar to an invincibility hitbox and an intangibility hitbox. Also, 's objects around his arsenal (such as his tilt attacks, smash attacks, aerials and special moves) possess the unability to be touchable, and they are not hurtboxes (giving them the properties of an invincibility hitbox and an intangibility hitbox, but they lack the intangible frames), so they give great advantages in seperations.
