Treasure of the Ocean Cave: Difference between revisions

Thank you very much to Davo for typing this summary, it's great! Definitely much better than anything I could have put together.
(Looks bad for now, still WIP)

The TAS starts by collecting the metal cap, returning next to the BLJ spot. The combination of stop+punch-trick+long jump allows Mario to reduce his speed so that he can strain back far enough, which is faster than a quickturn+LJ combo. Speed is gained via BLJing in the low ceiling spot under the rock, starting with -15.99 speed. This area used is quite precise with the BLJ being done at an angle which keeps Mario stuck for as long as possible (to get more speed). Mario breaks out of the ceiling when he reaches -826 speed. From there, the BLJ becomes a slope-BLJ, and so pause-buffering allows for more speed gain, up to a final speed of -1855.
After the BLJ, Mario turns around (clockwise) to move towards the water. By making Mario face into the wall slightly, he can still move but doesn't move quite as far. This is just enough to allow Mario to stay out of the water for an additional frame, while only losing a small amount of distance. Since entering the water divides Mario's speed by 4 (with the metal cap), this means he has 1 more frame at full speed. This ultimately saves 2 frames (the theoretical max is just under 3 frames here). Mario then enters the water, losing 3/4 of his speed, but he can now turn around in the water. He turns towards the area above the hole that leads to the chest star.
When Mario reaches the edge of the water, he enters the ceiling hitbox above the top of the hole, causing him to downwarp into the cave. He then exits the water, and turns as sharply as possible anticlockwise to enter the cave. Inside the cave, Mario clips through a wall, cutting a corner and saving time. He then clips under the raised platform with the chests. He eventually reaches the wall behind the chests, pushing on it for 1f which kills his speed. To start moving back towards the chests, Mario kicks against the wall, giving him negative speed.
During the kick Mario passes the first chest, activating it. He then turns to face the second chest and jumps. During the dust-frames he (barely) reaches the chest, activating it.  He then turns towards the third chest and jumps before dive/recovering. He will have to turn back the other way to face the correct angle to activate the chest later, so the angle chosen must balance allowing Mario to turn for as few frames as possible while still allowing him to actually reach the chest (without losing too much speed through straining). Davo saved a frame here by using a better angle than the previous run.
Mario then turns left to reach the required angle to activate the chest, using the chest's hitbox to hold him in place, before turning right again to head for the next chest. Once he reaches the required angle to activate the chest, he dives into it, activating it immediately. Davo saved a frame here by diving earlier than the previous run and hitting the chest earlier. After that, Mario collects the star. The optimal way to do this is to GP above it at the right time so you reach the bottom of its hitbox when it becomes collectable.
