Changes: Swimming Speed

Revision as of 07:22, 21 November 2019

The base Swimming Speed of the player without any fins or items in hand is around 5.7 meters per second, while fully submerged. Swim speed can be modified with fins crafted by the player using the Fabricator or Modification Station, or by equipping tanks or a Reinforced Dive Suit. Swim speed is also modified by holding tools or advanced hunger and thirst. Swimming at the surface increases swimming speed.

While underwater, Fins add 1.4 m/s to overall speed, whilst Ultra Glide Fins add 2.4 m/s.

Currently, the fastest way of traveling is the Prawn Suit /Grappling arm combo.

Swim speed is capped at an upper limit of 7.60 m/s and a lower limit of 1.90 m/s (Fully encumbered, holding a tool, no fins, underwater).

Swimming above water is faster than below water (base speed 7.4 m/s), and is also capped at 7.6 m/s

Equipping Oxygen Tanks and the Reinforced Dive Suit will slow swimming speed. Advanced states of hunger and thirst also reduce swimming speed, at a rate proportional to the amount of severe hunger or thirst.

Carrying an Ultra High Capacity Tank will decrease the speed by 1.0 m/s to 1.5 m/s (only the first 2 in the inventory will count towards decreasing speed). Strangely, no other type of air tank decreases speed when carried in the inventory.

Equipping any hand-held item (except the Seaglide) will reduce swim speed by 0.95 m/s.

When using the Seaglide, movement speed is a constant 11 m/s regardless of your equipment.

The Swim Charge Fins will only charge powered tools above a swim speed threshold of 2.0 m/s.

Effects on Swimming Speed (in meters per second)
Modifier	Underwater (m/s)	Surface (m/s)	Remarks
Base Swim Speed	5.7 m/s	7.4 m/s
Swim Charge Fins	+0	+0	Needs swim speed of 2.0 for charging
Fins	+1.4	+1.85
Ultra Glide Fins	+2.4	+3.1
Holding a tool	-0.95	-1.25
Advanced hunger ( less than 20%)	-0.05 per 1% below 20%		Max at 100% hunger is -4.00 m/s
Advanced thirst ( less than 20%)	-0.05 per 1% below 20%		Max at 100% thirsty is -4.00 m/s
Tanks and Suit
Standard O₂ Tank or HC O₂ Tank (Paperdoll/Inventory)	-0.4 / -0.0	-0.5 / -0.0
Ultra High Capacity Tank (Paperdoll/Inventory)	-0.4 / -1.0	-0.8 / -1.5	Penalty for carrying in inventory is maxed at 2 tanks.
Lightweight High Capacity Tank (Paperdoll/Inventory)	-0.0 / -0.0	-0.0 / -0.0
Reinforced Dive Suit	-0.95	-1.25	Other suits have no speed penalty

Note: "Inventory" refers to extra air tanks being carried. "Paperdoll" refers to the air tank that is equipped.

The values above are valid as of build 63177 (Nov 19, 2019)

-*'''NOTE: Swimming at the surface is double the underwater swim speed (but capped at 7.60 m/s)'''
-== Examples: ==
-)
-A player without any tanks, suit, or tool equipped in hand will swim underwater at 5.70 m/s
-If a tool is equipped, the swim speed will be 5.70 - 0.95 = 4.75 m/s
-If the player surfaces, the swim speed should be 5.70 x2 = 11.40 m/s. '''However, speed is capped at 7.60 m/s'''
-If a tool is equipped at the surface, the swim speed should be 4.75 x 2 = 9.50 m/s.''' However, swim speed is capped at 7.60 m/s'''
-)
-With a Reinforced Dive Suit equipped, 2 Ultra High Capacity Tank ( 1 in the UI Paperdoll and 1 in the inventory) and no fins, a player will swim underwater at:
-.70 - 0.95 - 0.61 - 1.21 = 2.93 m/s
-If a tool is equipped, the player will swim underwater at 2.93 - 0.95 = 1.98 m/s
-If the player surfaces, the swim speed without a tool is now 2.93 x 2= 5.86 m/s
-If a tool is equipped at the surface, the swim speed is 1.98 x 2 = 3.96 m/s
-* Note: If the player has swim charge fins equipped, no charging will occur underwater (Speed less than 2.0) but tools will charge at the surface while swimming (Speed greater than 2.0)
-)
-With normal fins equipped, a Reinforced Dive Suit and 3 Ultra High Capacity Tank (1 Paperdoll, 2 inventory),
-Total speed penalty from suit and tanks = 0.95+0.61+1.21+1.21 = 3.98 (+/- 0.01)
-However, this penalty is capped at -2.85 m/s
-Swimming speed underwater with no tool equipped = 5.70 - 2.85 + 0.95 = 3.80 m/s
-Swimming speed underwater with tool equipped = 3.80 - 0.95 = 2.85 m/s
-Surface swimming speed with no tool equipped = 3.80 x 2 = 7.60 m/s (at speed cap)
-Surface swimming speed with tool equipped = 2.85 x 2 = 5.70 m/s
