{{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. | |||

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. | |||

=== Punch Cancel === | === Punch Cancel === | ||
Punch cancelling is a method to begin running with a higher speed. The first frame of running has ~8.9 speed, however the first frame of punching (from standstill) has 10 speed. You can then cancel it into running with the joystick or into a jump by pressing A. This is useful as it reduces the amount of frames of movement needed for other movement starting options such as a slidekick or long jump. Note when you do a punch cancel, it must be done with a neutral joystick and therefore you can not arbitrarily change your angle. | |||
=== Quickturn === | === Quickturn === | ||
Once you enter the idle action of a quickstop, you then have a number of options for changing direction quickly. Buffered jumpkicks, walking at full magnitude with an arbitrary angle, punching off a ledge (usually to start dive grinding), or, in some rarer cases on very steep slopes, crouch sliding, can all be efficient ways to change direction after a quickstop. | Once you enter the idle action of a quickstop, you then have a number of options for changing direction quickly.

=== Slidekick Start === | === Slidekick Start === | ||
Starting movement with a slidekick is the fastest way to accelerate under certain conditions. When you begin a slidekick, your speed is set to 32, which is much higher than a long jump or buffered jump kick. However other starting movements like longjumps and jumpdives will catch up later on because of their superior acceleration. Instead, if you find a way to cancel the slidekick rollout and immediately dive, there's a high chance it will be faster. Sometimes you do not need to do the rollout and the slidekick is the fastest movement over shorter distances. (e.g. LLL re-entry movement) | Starting movement with a slidekick is the fastest way to accelerate under certain conditions.

=== Punching Off Ledge === | |||
At low speeds and trying to run off of a ledge, Mario will sometimes climb down to hang on the ledge. This is bad if you want to start a movement by dive-grinding, [https://youtu.be/qRHC035iVI8?t=28 quickly start a wing cap flight] or just falling off the platform in general. The ledge climb down only happens if you are in the walking action, however, so it is possible to avoid climbing down to the ledge by punching. | |||
TODO (mention both divegrinding application and fast flight application (like here: https://youtu.be/qRHC035iVI8?t=28) | |||
=== 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] | |||

When Mario is in a landing action on most surfaces, it will take 4 frames for him to come to a complete stop if you have no joystick input. After Mario has reached 0 speed, holding a very low magnitude on the joystick (12 or less, approximately) for 1 frame and then returning to neutral will allow him to enter the idle action very quickly. If you have any joystick input on the first 3 frames of a landing action, then you will maintain more speed (or lose more speed, if your speed is | When Mario is in a landing action on most surfaces, it will take 4 frames for him to come to a complete stop if you have no joystick input. After Mario has reached 0 speed, holding a very low magnitude on the joystick (12 or less, approximately) for 1 frame and then returning to neutral will allow him to enter the idle action very quickly. If you have any joystick input on the first 3 frames of a landing action, then you will maintain more speed (or lose more speed, if your speed is negative) throughout the action. You can still do a quickstop if you hold return to neutral on the 4th frame. Additionally, holding a low joystick magnitude for 2 frames after Mario has 0 speed will also allow him to enter an idle action as long as you return to neutral on the next frame. If you are entering a warp, then you can save time by returning to neutral and pressing Z after holding a low joystick magnitude for 1 frame. This will allow you to stop 1 frame sooner than you would if you did a regular quickstop. Note: on some slopes, it's possible to do a "1 frame quickstop," in which you only have to hold a low joystick magnitude for 1 frame before you can enter idle. As a general rule, if you're landing on any kind of slope, it's worth seeing if a 1 frame quickstop is possible. | ||

While in the idle action, if you enter the C-up camera mode and press Z, you can choose an arbitrary joystick angle that Mario will crouch with. You can then press A to perform a backflip. This kind of quick backflip is useful in some situations, like grabbing a closeby star above a platform you just ledgegrabbed onto. The reason you must press C-up is to stop mario from going into crawling, which he cannot backflip out of. | While in the idle action, if you enter the C-up camera mode and press Z, you can choose an arbitrary joystick angle that Mario will crouch with.
