Lava Boost is when Mario jumps after he comes into contact with lava, unless he is slide kicking (onto a lava floor). This action does not require A to be pressed. This is useful for various things, especially in the A Button Challenge.
Lava Boost on Wall
Many Airborne actions cancel into Lava Boost upon hitting a lava wall. This utility function is used for such transitions. (The only lava wall in SM64 is the one in Lethal Lava Land).
The following steps happen before Transition In:
- Update Mario's-facing-angle[1] based on the wall (atan z x normal)
- If forward velocity is less than 24, set it to 24
- Take 12 or 18 hurt counter damage, depending on if Mario has his cap.
- Play the Mario on fire sound
- update_mario_sound_and_camera (todo)
- Lava Boost(actionArg 1)
Transition In
See single jump for more details
- Mario's vertical speed is set to 84.
- If actionArg is 0, Mario's forward velocity is set to 0
Behavior
todo
Gravity
Just like Star Fall, the y-velocity decreases by 3.2 each frame with minimum velocity -65 instead of -75
Applications
Speedrunning
Some speedrunners use Lava Boost as a means to get around levels such as Lethal Lava Land faster. This is primarily useful for skipping long sections of the map, as instead of avoiding damage you can take a couple of hits to clear stars much faster.
Vertical Speed Conservation
If Mario lands on a floor after a lava boost, his vertical speed will not be set to 0. At max, Mario can have VSC80. This is used in an alternate method for LLL in the A Button Challenge to get to the platform with a spinning heart inside the volcano.
