Tadpole Trip Computer

Tadpole Trip Computer adds a compact vehicle instrumentation and trip-data HUD while piloting the Tadpole. It tracks movement, depth, power usage, efficiency, estimated operating range, and vehicle condition while maintaining independent trip records for each Tadpole.

The display appears automatically while piloting a Tadpole and is removed when exiting. Trip data is retained when leaving the vehicle and resumes when the same Tadpole is entered again. Each Tadpole maintains its own independent record, even if the vehicle streams out of the world and is later reloaded.

Why did I create this mod

• The Tadpole provides basic vehicle feedback, but longer exploration trips benefit from having actual navigation and operating statistics available at a glance.[/*]

• Tadpole Trip Computer turns the Tadpole into a more complete exploration vehicle by tracking where it has been, how efficiently it is operating, how much usable range remains, and how close it is to its operating limits.[/*]

By default, docking a Tadpole resets only that Tadpole's trip. Other Tadpoles retain their existing data.

The Trip Computer displays:

• Current speed[/*]

• Average moving speed[/*]

• Maximum speed reached[/*]

• Current depth[/*]

• Remaining depth before crush depth[/*]

• Vertical speed[/*]

• Maximum depth reached[/*]

• Trip duration[/*]

• Distance traveled[/*]

• Remaining power[/*]

• Power used during the trip[/*]

• Recent power drain rate[/*]

• Energy efficiency[/*]

• Estimated operating endurance[/*]

• Estimated remaining range[/*]

• Vehicle hull condition[/*]

• Chassis condition when available[/*]

Average speed is based on actual moving time rather than total trip time. Stationary periods therefore do not progressively lower the average.

Power efficiency and estimated range use cumulative moving energy consumption rather than a short rolling sample. This keeps the range estimate stable while the Tadpole is stationary. Recent power drain and endurance use a separate rolling window so they can respond to changing operating conditions.

Charging is handled naturally. Remaining power increases normally while charging, while cumulative trip power usage does not decrease. Efficiency calculations exclude charging intervals so external charging does not artificially improve the learned vehicle efficiency.

The Trip Computer also reads the Tadpole's live crush-depth value rather than assuming the vanilla limit, allowing Depth Left to remain compatible with upgrades or mods that alter maximum operating depth.

If Tadpole Radar is installed and enabled, the Trip Computer automatically positions itself directly beneath the Radar display. Tadpole Radar does not require modification or a special compatibility version

Requirements

• Subnautica 2[/*]

• UE4SS[/*]

Installation

Extract the TadpoleTripComputer folder into: Subnautica2 Binaries Win64 ue4ss Mods

The final structure should look like:

ue4ss

└── Mods

    └── TadpoleTripComputer

        ├── enabled.txt

        ├── README.txt

        └── Scripts

            └── main.lua

Start the game and enter a Tadpole. The Trip Computer will appear automatically while piloting it.

Uninstallation

Remove the TadpoleTripComputer folder.

Configuration

Configuration values are located near the top of Scripts main.lua.

Default font size:

local FONT_SIZE = 10Font size is automatically limited to a range of 8 through 14. Values below 8 are treated as 8 and values above 14 are treated as 14.

HUD line spacing, section spacing, and panel height automatically scale with the selected font size.

Default trip-reset behavior:

local RESET_ON_DOCK = true

local RESET_ON_EXIT = falseWith the defaults:

• Exiting a Tadpole pauses its trip.[/*]

• Re-entering the same Tadpole resumes its trip.[/*]

• Docking resets that Tadpole's trip.[/*]

• Other Tadpoles are unaffected.[/*]

Setting

RESET_ON_EXIT = truecauses the trip to reset when the player exits the vehicle.

Trip records are session data and are cleared when the game world/save is reloaded.

Release diagnostic logging is disabled by default and should normally remain disabled unless troubleshooting is required.

Tadpole Radar compatibility

If TadpoleRadar is installed and enabled, Tadpole Trip Computer automatically detects its enabled mod state and moves below the Radar HUD. If Tadpole Radar is absent or disabled, Trip Computer uses its normal upper-right position. This compatibility check does not scan Unreal UI objects and does not require any changes to Tadpole Radar.
