Instant walljumping is a technique in platformer games that allows a character to jump off a wall immediately after touching it, gaining additional height and momentum. To perform an instant walljump, the player must first jump towards a wall and then press the jump button again as soon as the character makes contact with the wall. This will cause the character to jump off the wall and continue moving in the same direction.
Instant walljumping is a useful technique for overcoming obstacles, reaching higher platforms, and gaining speed. It can also be used to perform various advanced maneuvers, such as wall climbing and pogo-sticking.
