Directional influence

Directional influence, often referred to as DI, is the ability to change the trajectory angle at which a character travels at when hit. DI can alter, but not completely change, the original launch trajectory and cannot control how hard a character is hit.

Inputs and technical details
By directing the trajectory angle perpendicular to the knockback angle, the trajectory angle can be adjusted by up to 18°.

Survival DI
Survival DI consists of adjusting the characters knockback trajectory towards the upper parts of the blast zones in order to prevent a KO. This is most often used on attacks that are extremely strong.

Combo DI
Combo DI consists of adjusting the characters knockback trajectory away from the opponent in order to increase the distance between both players and make it more difficult for the opponent to follow-up.
