'''Directional influence''' (usually abbreviated '''DI''', and known officially as '''launch shuffling''') is the control the receiver of an attack has over their trajectory. Each attack sends its target in a particular direction; DI can be used to alter, but not completely change, this original trajectory. DI is executed by holding the control stick in any direction during [[freeze frames]] from an attack, before the character is launched. | '''Directional influence''' (usually abbreviated '''DI''', and known officially as '''launch shuffling''') is the control the receiver of an attack has over their trajectory.

Directional influence does not exist in the original ''Super Smash Bros.''; only [[smash directional influence]] does. Coupled with [[hitstun]] being much higher than in later installments, this contributes to the ease of combos in said game; there is usually no way for a character to escape a combo once it has been started, often leading to a [[zero-to-death]]. | Directional influence does not exist in the original ''Super Smash Bros.''; only [[smash directional influence]] does.

To determine the effective trajectory, the position of the control stick is read on the last frame of [[hitlag]]. [[ASDI]] is usually triggered by this as well. The highest deviation of trajectory is produced by directions perpendicular to the original knockback angle of the hitbox and amounts to approximately 18°, while also depending on how much the control stick is tilted in said direction; tilting it by a lesser amount will cause a weaker deviation. Holding directions that are parallel to the original angle will produce no survival DI at all. Because the possible DI angles are [[Media:Angles.png|not distributed equally]] (see diagram to the right), knockback angles within 17° of vertical or horizontal can be trajectory DI'd to a lesser degree, as no true correspondent perpendicular angle is available. | To determine the effective trajectory, the position of the control stick is read on the last frame of [[hitlag]].

Survival DI consists of altering the knockback direction towards the upper corners of the screen so that more distance is required to reach the [[blast line]]s, effectively preventing a KO if the knockback was high enough to push the character into them with the original trajectory, but not enough to do so with the new trajectory created by the DI. Usually, if the attack's trajectory is almost entirely vertical, merely holding the control stick horizontally is needed, while if it is more horizontal, it must be held in a diagonally upward angle. | Survival DI consists of altering the knockback direction towards the upper corners of the screen so that more distance is required to reach the [[blast line]]s, effectively preventing a KO if the knockback was high enough to push the character into them with the original trajectory, but not enough to do so with the new trajectory created by the DI.

The narrower angle change provided by DI in ''Smash 4'', coupled with LSI's aforementioned effects, significantly reduce its effectiveness for escaping combos and surviving KO moves for longer, as less space is created between the victim and an attacker wishing to continue a combo, while DIing horizontal launchers at high angles to prevent [[edgeguard]]s and center stage KOs now results in increased distance away from the stage and the resulting angle not being as vertical as before. DI continues to be a useful technique in competitive play regardless, however, as it still has a significant effect in moderately strong moves that can otherwise secure KOs under certain conditions, such as [[throw]]s boosted by [[rage]] near the edge, and with the changes to [[hitstun]] canceling from ''Brawl'' making true combos prevalent again, it can be used to avoid certain deadly setups and/or 50-50s such as {{SSB4|Captain Falcon}}'s {{mvsub|Captain Falcon|SSB4|down throw}} into [[Knee Smash]] from a dash grab. | The narrower angle change provided by DI in ''Smash 4'', coupled with LSI's aforementioned effects, significantly reduce its effectiveness for escaping combos and surviving KO moves for longer, as less space is created between the victim and an attacker wishing to continue a combo, while DIing horizontal launchers at high angles to prevent [[edgeguard]]s and center stage KOs now results in increased distance away from the stage and the resulting angle not being as vertical as before.

During the initial release of {{for3ds}}, LSI affected any angle with no restriction, giving it a significant effect on moves with largely vertical angles, while not incurring any significant compromise in DI due to the control stick already having to be held entirely vertically to achieve the full effect of LSI. More specifically, vertical finishers (like most [[up smash]]es) and [[meteor smash]]es could be survived for longer by holding down, while vertical combo moves (like most [[down throw]]s) would stop working earlier if the victim held up to be launched farther away from the attacker via LSI. Starting in patch [[1.0.4]], LSI has no effect if the launch angle is between 65° and 115°, or between 245° and 295°, preventing such moves from having their knockback altered by it and leaving DI as the only other, much less significant option against them.<ref>[https://twitter.com/Ruben_dal/status/820897784496852992 Ruben on Twitter: "In the meantime visuals to understand LSI: how it works, its conditions and multiplier formula"]</ref> However, this restriction takes DI into account rather than reading the base angle, which allows moves with angles differing from any of these thresholds by less than | During the initial release of {{for3ds}}, LSI affected any angle with no restriction, giving it a significant effect on moves with largely vertical angles, while not incurring any significant compromise in DI due to the control stick already having to be held entirely vertically to achieve the full effect of LSI.

The most notable example of this fault is {{SSB4|Charizard}}'s {{mvsub|Charizard|SSB4|up throw}}, which can normally KO at around 125%, but due to its angle of 70°, DIing it at roughly 295° deviates it enough to get it out of the LSI-disabled range and therefore creates both optimal DI and LSI, rendering the move unable to KO until around 155%; this is in stark contrast to {{SSB4|Mewtwo}}'s {{mvsub|Mewtwo|SSB4|up throw}}, which due to its angle of 90°, is immune to LSI and barely affected by DI, only KOing 4% later with the latter in effect. | ||

''Ultimate'' reuses the directional influence mechanics from the latest version of ''Smash 4'', with both DI and LSI being present, and the latter still having a restriction for vertical angles. As a new aesthetic indicator, when DI is applied, the game briefly displays a streak of blue light pointing along the character's final launch angle. Additionally, during a [[Special Zoom]] or Finish Zoom, the window for the victim to DI ignores the slowdown effect, preventing them from having more time to DI properly and survive for longer when either event occurs. | ''Ultimate'' reuses the directional influence mechanics from the latest version of ''Smash 4'', with both DI and LSI being present, and the latter still having a restriction for vertical angles.
