Gravity
Gravity applies a constant downwards acceleration to the player, affecting vertical speed and how quickly the maximum falling speed is reached. The default gravitational acceleration is 123 mph per second[1], with falling speed capping at 51 mph[2]. Certain sources may add modifiers to both gravity and the maximum falling speed to increase or decrease their effects.
Modifiers
| Source | Effects | |
|---|---|---|
| Space | Gradual decrease in gravity the closer the player is to the upper map limit, down to 25% default gravity, or 10% in Don't dig up or Get fixed boi worlds. | |
 |
Water | 50% default max fall speed and 20% default gravity. |
 |
Lava | |
 |
Honey | 30% default max fall speed and 25% default gravity. |
 |
Shimmer(Desktop, Console and Mobile versions) | 37.5% of default gravity. |
 |
Distorted(Desktop, Console and Mobile versions) | Max fall speed is increased by 1 mph. Completely removes gravity. Vertical speed is determined by the player's current vertical speed and the horizontal position. |
 |
Shimmering(Desktop, Console and Mobile versions) | 90% of current max fall speed. 90% of current gravity. |
 |
Merfolk(in water) | 70% default max fall speed and 75% default gravity. |
 |
Featherfall | 33.33% of current max fall speed and gravity (10% while holding ▲ Up). No effects while holding ▼ Down. |
 |
Djinn's Curse(Desktop, Console and Mobile versions) | |
 |
Slimy Saddle(Desktop, Console, Old-gen console and Mobile versions) | 200% default max fall speed. |
 |
Gelatinous Pillion(Desktop, Console and Mobile versions) | |
 |
Trident(in water) | (Desktop, Console and Mobile versions) 60% default max fall speed and 62.5% default gravity (20% and 25% while holding ▲ Up). |
 |
Portal Gun(Desktop, Console and Mobile versions) | 350% default max fall speed. |

Here is the formula to calculate gravity modifier: modifier = (x - offset - 60) * factor1/factor2. Thereafter, the final result will be limited between 0.25 and 1 (0.1 to 1 in Don't dig up and Get fixed boi worlds). Meanings of the parameters are listed below:[3]
xequals to the player's distance to the top border of the world (measured by tiles).offsetis determined by the world size, where a large world is 20, a medium world is 15 approximately, and a small world is 10.factor1means whether the world uses the world gen of Don't dig up or Get fixed boi. A normal world is 6, while the former both are 1.factor2equals to the distance of the world's Surface (0 feet) to the world's top border.
Reversing gravity

The player can gain the ability to reverse their gravity by consuming a Gravitation Potion or equipping a Gravity Globe(Desktop, Console and Mobile versions). Pressing the ▲ Up key flips the player's gravity so that they fall up instead of down. In multiplayer, this only affects the player with the item used. Gravity can be changed back to normal afterward with the same key, and can be toggled freely at any time (provided the Gravitation Potion's buff is active or the Gravity Globe is equipped) at no cost and with no cooldown.
Notable aspects of reversed gravity include the following:
- Flipping gravity resets the player's fall distance. They can flip gravity rapidly before landing to avoid taking fall damage from a long fall.
- Hitting the upper limit of the map while gravity is reversed will not damage the player, but will instead cause gravity to revert to normal. This will not reset the flight timer of wings and Rocket Boots.
- The Wisp in a Bottle, as well as its controls, remain upside down in reversed gravity.
- Fishing is possible in reverse gravity; the fishing bobber will fall "upward" into the water.
Being in reversed gravity also applies certain restrictions:
- Mounts cannot be summoned.
- Platforms will not stop players falling upwards, and they will instead fall through them.
- Wings cannot be used to glide.
- Golf(Desktop, Console and Mobile versions) cannot be played; the player will not even be able to swing the club.
- Kites(Desktop, Console and Mobile versions) can be used but will retain their normal orientation.
- Shimmering(Desktop, Console and Mobile versions) is not possible; gravity will revert to normal as soon as the player touches Shimmer.
- With the Flower Boots(Desktop, Console and Mobile versions) equipped, flowers will grow on the grass block that the player's head touches. The block which the player is actually standing on will not sprout upside-down flowers, nor will it sprout vines.
Trivia
- In reversed gravity, the text during the credits appears upside down as well.

- Fixed a reverse gravity issue where the Floating Piggy Bank's mouseover detection would be in the wrong direction.
- Fixed a reverse gravity issue where Blizzard Staff-style weapons would converge in the opposite direction of where the player aimed.
- Fixed a reverse gravity issue where the player would get stuck on hammered platforms.
- Fixed an issue where Forbidden Set's ring did not flip properly in reverse gravity.
- Fixed a reverse gravity issue where some weapons wouldn't flip with the player.
