=== BLJ === | === BLJ === | ||
{{main|BLJ}} | {{main|BLJ}} | ||
BLJ requires Mario to land from a longjump in less than about 8<!--someone verify this number--> frames. This can be achieved using a small ledge (such as stairs), a steep slope, an upwards-moving platform, or a ceiling. | |||
A notable optimisation is the use of neutral joystick input during landing frames to avoid losing speed. It is not applicable to side BLJs though. | |||

TODO | TODO: shallow water, unit squares maybe | ||
==== | ==== Side BLJ ==== | ||
Side BLJ utilises a ledge that is between 7 and 30 units tall. Mario faces almost parallel to the ledge, the smallest possible angle upwards. He then lands on the lower floor next to the ledge, longjumps and strains onto the ledge, landing instantly, then moves back down because of his angle. This is repeated to perform a side BLJ. | |||
==== Elevator BLJ ==== | ==== Elevator BLJ ==== | ||
Elevator BLJ utilizes a platform moving upwards by [some] units per frame to cancel a long jump's vertical ascent. | |||
They are one of the only few hyperspeed methods that can reach PU speeds, and the only method viable in speed TASing. | |||
==== Ceiling BLJ ==== | ==== Ceiling BLJ ==== | ||
Ceiling BLJ utilises either a low ceiling or an exposed ceiling. A ceiling both holds Mario in place and cancels his vertical speed. Mario must hit the ceiling on the first quarter-step, so he never moves off the floor. | |||
It is often possible to hit the ceiling for 2 frames during the initial longjump to cancel Mario's vertical and horizontal speed, allowing to start the BLJ much faster. | |||

=== Optimal Speedkick === | === Optimal Speedkick === | ||
For a speedkick, the joystick magnitude must be 48 or less. The optimal input is whatever has the greatest component in Mario's facing direction. | |||
=== Buffered | |||
If you hold A either before the first frame that Mario is able to move, or, if landing from the air, before the landing action has started, then you can (while still holding A) press B to do a buffered | Input Direction Lua includes a speedkick function, but it only works properly in one version. The one currently in the repack does not do it correctly. | ||
=== Buffered Kick === | |||
If you hold A either before the first frame that Mario is able to move, or, if landing from the air, before the landing action has started, then you can (while still holding A) press B to do a buffered kick. If starting from idle, this allows you to choose an arbitrary angle to kick with. Note: a jumpkick (where you press A and B on the same frame, or press B after A) does not allow you to choose an arbitrary angle from idle. | |||
=== Speedpunch === | === Speedpunch === | ||
When Mario is on the ground, pressing B will do a punch rather than a dive if the joystick magnitude is 48 or less. A must not be held, otherwise Mario will kick. | |||
This is usually done on the first possible frame after landing, which preserves speed. It is not possible if landing from a longjump. It is also possible from braking, for example a C^ slide. | |||
=== Pole Speed Redirection === | === Pole Speed Redirection === | ||
Grabbing a pole preserves sliding speed. It can be reactivated by touching a floor, which puts Mario in the idle action, then pressing Z and a direction on the joystick. | |||
If Mario grabs the pole from below the base, he will release it instantly. If this puts Mario on a floor, he will go into idle, allowing for a very fast speed redirection. | |||

=== Hyperjump === | === Hyperjump === | ||
The initial vertical speed of a single or double jump depends on Mario's horizontal speed before the jump. Specifically, it is <math>\frac{\text{hspd}}4 + 42</math> for a single jump and <math>\frac{\text{hspd}}4 + 52</math> for a double jump. The height of a jump scales with the square of that speed. This means that with high horizontal speed, Mario's jump will go very high. | |||

=== Eru Drop === | === Eru Drop === | ||
When walking at a minimal magnitude (8 units from neutral in any direction on TASInput), Mario tip-toes in place without moving much. However he is not constantly moving forward. On some frames, Mario actually moves backwards. Abusing this, we can walk off a ledge backwards to initiate an instant double jump (which can lead into a triple jump), fall onto a platform below whilst facing it or instantly dive recover. (There are probably more options out of an Eru drop as well.) To do this, Mario needs to be positioned less than a unit away from the ledge, walk facing away from the ledge and Mario should drop off of the ledge. It is advised to use STROOP's map tab to do this. | |||
The fastest an Eru drop can be performed is in 3 frames from when Mario begins walking, however doing it in 3 frames gives less freedom as to what angles you can fall off the ledge with. | |||
It is called the Eru drop as it was found by [https://youtu.be/Tl1qDika4Bk?t=7 Japanese TASer Eru] | |||

By touching OOB or the death barrier, Mario can initiate the death fade out before getting a star. The setup to do it may be longer than the single star time, but by doing a DSG we can avoid the star dance and the animation Mario does out of the painting and the save and quit, which is longer than Mario's animation he does when he dies. (His death animation also makes him face the painting, allowing for a punch cancel trick to be used for re-entry) | By touching OOB or the death barrier, Mario can initiate the death fade out before getting a star.
