Knockback is the distance a character flies when the character is hit by an attack. It is measured in pps, or pixels per second. For example, Mario's fully charged forward smash does 9 pps of forward knockback to an opponents Mario at 0% damage. A player can avoid receiving knockback by dodging or using an attack that gives invincibility frames or knockback resistance.
Conditions
This is a list of conditions the knockback of an attack depends on:
- Current % damage of the victim.
- Weight and Gravity of the victim.
- The staleness of the move used.
- The Damage Ratio. The Damage Ratio is the multiplication of the knockback.
Knockback values
Each hitbox of a move has two knockback values: a base knockback and a knockback scaling (also known as knockback growth). Base knockback is the minimum amount of knockback that an attack can deliver (in normal circumstances), and knockback scaling is a factor that controls how much knockback increases as damage increases. Moves with high base knockback deal high knockback under any circumstances, such as the swing of the Home-Run Bat. They additionally tend to be more effective at KOing when less knockback is needed (ex. light characters who are near the ledge or when a opponent is handicapped to sustain more knockback). On the other hand, moves with high knockback scaling take less damage to reach KO potential, such as Bomberman's forward smash. They additionally tend to be more effective at KOing when the opponent requires more knockback to be KO'd (such as against heavier characters, when far away from a stage's blast line, or when an opponent is handicapped to sustain less knockback). Techniques such as Directional Influence and Momentum canceling who help extend a players survival becomes less effective the stronger an attack's knockback scaling is.
Set knockback
Set knockback, sometimes referred to fixed knockback, is a property of some attacks where the knockback dealt by the attack does not depend on the opponent's percentage or how much damage the attack does. This results in it dealing the same amount of knockback regardless of Stale-move negation.
List of set knockback attacks
- Many standard attacks
- Fox's up aerial (first hit) and Reflector
- Kirby's Inhale (when he spits out the opponents or absorb their standard special move)
- Mario's down aerial
- Wario's Chomp
- Goku's ledge attack
No knockback
They're attacks that due damage, but deal zero knockback. These attacks are normally used to damage the opponent without making them flinch, but the opponent is still able to move freely while they're being attacked.
