'''Gravity''' is a force that draws matter together, which in everyday life causes objects to accelerate down towards the Earth's center of mass. Simulation of gravity in ''[[Super Mario 64]]'' is less consistent than real life and depends significantly on the object and the situation. This could be an acceleration or more of a velocity depending on the situation.

[[Mario]] generally does a series of checks and changes his velocity depending on the situation. Once Mario performs any changes to his vertical speed, he is done with gravity and applies no more changes. As such, at the end of each main condition branch, Mario explicitly skips the rest of the gravity checks, making them mutually exclusive.

Gravity is the general idea of accelerating towards a center of mass, often "down". In Mario 64, this is less consistent than real life and depends significantly on the object and the situation. This could be an acceleration or more of a velocity depending on the situation.

== Mario ==
Mario generally does a series of checks and changes his velocity depending on the situation. Once Mario performs any changes to his vertical speed, he is done with gravity and applies no more changes.

# If Mario is in the [[twirling]] action and has negative Y-speed:
## If Mario is spinning with a yaw speed faster than 1024:
##* Mario's terminal velocity is set to -75 * 1024 / Mario's yaw speed.
##* Mario's vertical speed is increased by -4 * 1024 / Mario's yaw speed.
## Otherwise:
##* Mario's terminal velocity is set to -75.
##* Mario's vertical speed is decreased by 4.
## If Mario's vertical speed is less than his terminal velocity, it is set to the terminal velocity instead.
## Mario now stops these gravity checks.
# If Mario is in the [[Shot From Cannon|shot from cannon]] action:
## Mario's vertical speed is decreased by 1.
## If Mario's vertical speed is less than -75, it is capped/set to -75.
## Mario now stops these gravity checks.
# If Mario is in the [[Long Jump|long jump]], [[Slide Kick|slide kick]], or [[BBH Enter Spin|BBH enter spin]] actions:
## Mario's vertical speed is decreased by 2.
## If Mario's vertical speed is less than -75, it is capped/set to -75.
## Mario now stops these gravity checks.
# If Mario is in the [[Lava Boost|lava boost]] or [[Fall From Star Grab|fall from star grab]] actions:
## Mario's vertical speed is decreased by 3.2.

## Mario's vertical speed is decreased by 1.6.
