Hitbox

Hitboxes are the areas in which an attack can hit an opponent. For example, if a characters uses a slash attack, the hitbox is focused around the area where the weapon slashes. Attacks with longer range have a hitbox that extends farther.

Types of HitBoxes

 * HitBox - this box represents a damagable area- The bodies of the characters and destructible stage areas.
 * Attack Box - this box represents a damaging hitbox- These can be found on attacks and projectiles.
 * Hand Box - the box which allows ledge grabbing. Also, not always used, it is present in the idle frame.
 * Grab Box- only used in grab attacks. This box grabs opponents and holds them in place. These can be found on grabs as well as Ganondorf's Dark Dive, Captain Falcon's Falcon Dive, Kirby's Inhale, Yoshi's Egg Lay, and Bowser's Koopa Klaw. All these attacks share the characteristic of being able to penetrate the enemy's shield
 * ItemBox - Item placeholder. This is used to place hold for every item in the game.

Disjointed Hitbox
Disjointed hitbox describes an attacking red collision bubble that is not attached to the vulnerable yellow bubble. These are generally found on weapons, like swords or hammers. A disjointed hitbox, if attacked, cannot hurt the character. For example, If Marth attacks Ness's PK Fire with his forward smash, Marth will not be affected. However, if Mario punches the PK Fire, he will sustain damage. Some disjointed hitboxes, such as Snake's up tilt, are placed in very unexpected spots and, as such, can be used to surprise an opponent, not expecting a hitbox to extend so far. Famous disjointed hitbox's include Snake's Up tilt in Brawl and Kirby's up tilt in Smash 64.
