'''Mario Wings to the Sky''' is the fifth mission of [[Bob-omb Battlefield]]. To complete the objective and spawn the star, Mario must fly through five rings of coins and collect the [[secret|secrets]], located in each ring's center.

Below is a history of the WR TAS for MWttS. The current state is thought to be nearly maxed, with dar gos and Plush having saved many frames over 2012's 120 TAS.

{{TAS History}}

There are 5 secrets, which are regions that Mario must pass through in order to spawn the star. Each secret as an origin point with a [[hitbox]] of 137 [[units]], cylindrically extending upwards by 100 units and downwards by 160 units.<ref>[https://youtu.be/H6L5rpuGxYI "Secret and Coin Hitboxes" by UncommentatedPannen]</ref> All secrets have a coin overlapped onto it with the same cylindrical hitbox of a radius of 137, but only extending 64 units up and 160 units down. Additionally, a ring of 8 coins is present vertically encircling the secret.

Gathering all secrets present a huge problem in the [[A Button Challenge]] as the secrets are located way above the ground, with the 5th secret being more than 5000 units high from the origin of the course. In [[Coinless Challenge|Coinless]] challenges, the difference in hitbox means that the secret can be triggered without collecting the coin by accessing the upper 32-unit region, but unfortunately, the top coin of the ring (located at 200 units above the secret) overlaps the region completely. For both challenges, extreme techniques are employed to complete the herculean task.

Previously, on August 31, 2013, pannenkoek2012 collected the star with 1 A Press, which was used to launch from the [[cannon]] with a [[Wing Cap|wing cap]] to collect the secrets in the traditional way. At the time, it was believed that constructing a [[Goomba Structure#Goomba Bridge|goomba bridge]] by [[cloning]] is impossible, as the game has a limited number of object slots that can be used, and techniques of making more efficient goomba structures were not discovered yet. The method to create a goomba bridge that requires the least number of goomba clones at the time requires an exponential number of clones.

It was known that the [[Hat in Hand]] can release an object remotely at the [[HOLP]] (held object's last position) because the HOLP does not update when Mario has a hat in hand.  

With the introduction of [[Goomba Cluster|Goomba cluster]]s and [[Goomba Structure#Goomba Oasis|Goomba oases]], the required number of goombas quickly dropped down from exponential to quadratic, leading pannekoek2012 to develop a strategy to collect all secrets. Goomba clusters are created by releasing a group of goombas using the same HOLP but from different angles, allowing multiple goombas to stack at the same location. However, due to overlapping hitboxes of these goomba clones, each goomba only has a thin region where it can be interacted with, so Mario needs to be maneuvered very carefully. The goomba oasis is created by using [[transport cloning]], which occurs when the object is being pushed by an enemy, and releases the clone at the midpoint between its position and the HOLP, but at the HOLP's height, allowing a massive number of goombas occupying the oasis and bridging between the fourth and fifth secrets.

The TAS run was completed on May 29, 2015. It took 55 hours to create, with 2 years of planning, resulting in a run that takes 56 minutes to finish. The HOLP takes 28 goombas to reach, the oasis consists of 7 goombas, and the final [[Goomba Structure#Goomba Staircase|goomba staircase]] takes 36 goombas to bridge up the oasis, totaling 71 goombas to complete the mission.

In order to create a goomba oasis at the ideal location, a specific HOLP needs to be achieved beforehand. Precisely, the HOLP is set at (x, y, z) = (3592, 5170, -42). In the single-star basis, the HOLP can be achieved by building a goomba staircase consisting of 28 Goombas. The process would take 22 minutes to complete<ref name="comparison">[https://youtu.be/tKabwMxQ3Qo BoB MWttS Faster HOLP Real-Time Comparison by UncommentatedPannen]</ref>.  

For the first, second, and third secrets, Mario uses [[Backward Shell Hyperspeed]] in order to build up high negative speed to launch off from the mountain, allowing the lower three secrets in the air to be collected.  

In the ABC run of this star, the goombas in the oasis created by transport cloning are in the following positions<ref>[https://imgur.com/a/HANeE MWttS Goomba Position by pannenkoek2012]</ref> according to Pannenkoek:

:''Video (Coinless): [https://youtu.be/QZrZgaU2z6Y "SM64 - Mario Wings to the Sky - Coinless"] ''

More complicated strategies were required to reach the fourth secret<ref>[https://docs.google.com/document/d/1jymPs9agwskYzc1qCc4xVUA7pgi1Ymnyy35SXjuCePU/edit SM64 - Mario Wings to the Sky - Coinless - Secrets Breakdown]</ref>. Mario began by setting the HOLP somewhere in the air and putting a clone of an object with a hurt hitbox, such as a bowling ball. To do so, Mario flew to the flagpole with hat-in-hand glitch and dropped a bowling ball clone by releasing it at the flagpole (spawning it at the flagpole's height but at the HOLP laterally). Then, Mario flew towards the fourth secret with a clone, got hurt by the bowling ball, and removed the top coin by premature cloning while falling through the secret's hitbox. Because Mario was hatless, Pannenkoek held the A button during the descent to prevent fall damage killing Mario.

CCC Challenge stands for Coinless, Capless, and Cannonless. The restriction of coinless was already difficult to circumvent, and at the time the coinless run was made, it was thought to be impossible. However, as more advanced techniques such as [[Goomba Staircase#Goomba Cluster|goomba cluster]]s, [[PBH|pause buffered hitstun]] and [[Parallel Universe]]s were found, Pannekoek began planning a route to get the secrets without collecting coins and without the aid of Wing Cap and cannons.

In Bob-omb Battlefield, the ring of coins surrounding the secret is only loaded one frame after Mario enters the activation radius, and not on the frame Mario activates it. Therefore, there is a one-frame window where Mario can collect the secret without touching the coins, but in order to do so, Mario needs to be move at more than 2000 speed<ref>[https://youtu.be/j7nY_Fu1HPE "BoB Coinless Secret using Hyper Speed" by UncommentatedPannen]</ref>, which is 10 times faster than the speed used in hyperspeed flying with wing cap in 120-Star TAS speedrun.

To execute this strategy, Pannekoek constructs a [[Parallel Universe|PU]] route. For the first secret, Mario reaches negative 1.66 million speed (3.83 million for the second secret) by [[BLJ#Pause BLJ|pause-buffered BLJs]] to navigate to "midway point"<ref name="PU">According to [https://imgur.com/a/Qg91o Pannenkoek's workshop], the "midway" point is (x = -1, z = -5) in the PU grid for the first, third, and fourth secret, and (x = -11, z = -4) for the second secret. The "hill" point is (x = -2, z = -2) in the PU grid for all 4 secrets. Mario will also cross a "midair" point at (x = -1, z = -1) for one frame before reaching the secret. </ref> with an [[Overflow Jump]] (OJ), dropping down to 0.98 million speed (speed drops are done by rapidly pressing A) in order navigate up the hill<ref name="PU"/> with another OJ, and finally dropping down to about 404 thousand speed to horizontal launch back to the main map while collecting one of the secrets. In order to have Mario stop exactly on the main map collecting the secret, the movement is set so that his final launch movement has one of its [[Movement Steps|Quarter Step]] being out of bounds.

The procedure was done in the following steps:
