A-sticking
A-sticking, also known as T-sticking, is a controller configuration where the C-Stick (right Control Stick) is set to Attack instead of Smash. A-sticking is derived from the C-Stick being set to a different function, similar to B-sticking, and it is a shortcut for standard attacks, hence the A; T-sticking is derived from the stick being set to Tilts.
These are techniques that are possible with the A-Stick setup.
Central movement
If the player tilts the C-Stick in a diagonal direction in midair, the character's neutral aerial will be executed. Since this doesn't require the player to have the left control stick in any specific position, they can move horizontally and perform their neutral aerial at the same time.
Instant dash attack
If the player tilts the C-Stick in any direction right after they start their dash, they can start up a dash attack during the frames of the start up dash animation instead of their forward smash. Since doing this performs a dash attack, they can cancel it into an up smash as well.
No fast fall down aerial (Brawl)
In both Super Smash Bros. Melee and Super Smash Bros. Brawl, if the player uses a down aerial by tapping the Control Stick down and pressing the A button, they fast fall as they do it. In Melee, players can instead just use the C-stick to not bother having to lightly tilt the Control Stick, as it allows them to execute the down aerial without fastfalling regardless of whether they tapped the C-stick or not. If the C-Stick is set to Smash in Brawl, though, they will fast fall when doing the down air, even if it is tilted lightly. To avoid this then, players can set the C-stick to Attack. In Super Smash Bros. for Wii U, the C-stick no longer causes the player to fastfall when executing a down air with it while set to Smash.
Attack in midair without losing momentum (Smash U)
In Super Smash Bros. for Wii U, presumably due to a bug involving the C-stick's new ability to charge smash attacks by itself, having it held in any direction while set to Smash will cause the player to lose their momentum (in midair) and be unable to move, attack or grab (inputting a grab will cause the character to shield instead) until the stick is released. This prevents the C-stick from effectively working as a substitute to the Control Stick + A Button to perform aerials, as it will now cause the player to lose momentum, even if the C-stick is held in the direction the player is moving. While the C-stick can be quickly thrusted and returned to its neutral position, it doesn't provide any significant advantage over the Control Stick + A method, since both will now cause the player to lose momentum.
As such, setting the C-stick to Attack prevents this from happening, making A-sticking the optimal choice for players to efficiently use aerial attacks while keeping their midair momentum, like in the previous games. In Super Smash Bros. for Nintendo 3DS, the C-stick on the New Nintendo 3DS is always set to Smash without a possibility of customization, causing this problem to always occur in said game.
Trivia
- Quickly thrusting the A-stick in random directions will make the player jump and will continue to do so until the player stops thrusting the A-stick.
- If the C-Stick is tapped in backwards diagonally, the player will perform a jab, similar to the way a neutral aerial is performed in this setup.
