Moves the contents of the Exosuit Cargo inventory slot at row 6, column 4 to row 6, column 5. Anything in the destination is overwritten (use "info -i -c exosuit_cargo -t all" to check contents before moving, or use the swapinv command).


recharge

Recharges technology items. Certain technology items in the game have an associated energy capacity that discharges with use. Some examples are the exosuit life support system, the radiation deflector, etc. In the ship, hyperdrive, launch thruster, pulse engine, and other items also have this behavior. Some multitool and vehicle technology items also behave this way. This command will "recharge" these items back to their full capacity.

  -b, --backup-dir          If provided, will write the selected game-save to a decrypted JSON file in the
                            specified directory.

nmssavetool

  -c, --inventory-groups    (Default: exosuit ship freighter vehicle container) Which inventories to refill.

  -b, --backup-dir          If provided, will write the selected game-save to a decrypted JSON file in the
                            specified directory.

refurbish

Refurbish is equivalent to running the recharge, refill, and repair commands independently.

  > nmssavetool help refurbish 

nmssavetool

  -c, --inventory-groups    (Default: exosuit ship multitool freighter vehicle container) Which inventories to
                            refurbish.

  -b, --backup-dir          If provided, will write the selected game-save to a decrypted JSON file in the

Examples:

  > nmssavetool refurbish -g 1 -c ship

Refurbishes all ship inventories for the game save slot 1.


relocate

Relocate the player, within the current galaxy, to a position specified using one of several coordinate representations. Currently three formats are supported:

  1. Signal scanner coordinates. These are the coordinates displayed by any signal scanner in game. They appear as 4, 4-digit hexidecimal numbers separated by colons (example, 0C93:0080:02B1:0202).
  2. Portal coordinates. The game has 16 portal glyphs, each of which represents a hexidecimal digit. Several online sites and tools allow you to convert a sequence of glyphs into a 12-digit hexidecimal number. This command supports coordinates in this representation.
  3. Voxel coordinates. Within the game-save file, coordinates are specified as X, Y, Z, and Solary System Index values. You may directly provide these values to this command. This is useful when trying to replicate a position from another game save.

When moving the player, it is generally safer to reset the player's planet index and LastKnownPlayerState so that the player is positioned near a valid planet and in his ship. The program will do that by default, but if desired that behavior can be disabled with the --no-reset-planet and --no-reset-to-ship flags.

  > nmssavetool help relocate 

nmssavetool

  -c, --galactic-coordinates    Set the player position using the galactic coordinates displayed by signal
                                scanners.

  -p, --portal-coordinates      Set the player position using portal coordinates.

  --voxel-coordinates           Set the player position using the voxel coordinates used within the save-game
                                file. Format is (x,y,z,ssi).

  --galaxy                      Set the galaxy index (0 = Euclid Galaxy, 1 = Hilbert Dimension, 2 = Calypso
                                Galaxy, etc.)

  --planet                      Set the planet index

  --no-reset-planet             Normally when relocating the player, the player's planet value is set to zero,
                                so that the player's position is compatible with all star systems. Set this
                                flag to disable that behavior.

  --no-reset-to-ship            Normally when relocating the player, the player's last known state value is set
                                to 'InShip' so the player spawns inside his ship. Set this flag to disable that
                                behavior.

  -b, --backup-dir              If provided, will write the selected game-save to a decrypted JSON file in the
                                specified directory.

  --full-backup                 If provided (along with -b/--backup-dir), will archive the full game-save
                                directory in addition to the decrypted JSON game-save file.

Examples:

  > nmssavetool recolocate -g 1 -c 0C93:0080:02B1:0202

Relocate the player, within the current galaxy, to the position at the signal-scanner coordinates, 0C93:0080:02B1:0202. The player will be placed within his ship and reset on or near the first planet (planet 0).

  > nmssavetool recolocate -g 1 -p 020201AB2494 --no-reset-planet --no-reset-to-ship

Relocate the player, within the current galaxy, to the position at portal cooredinates, 020201AB2494. The player planet and last known player state will be left unmodified (use with caution).

  • Every feature anyone has ever requested, except for a GUI :)
  • Several new inventory commands giving the ability to manipulate inventory contents. Add, move, swap, or delete inventory items

  • New command: backup. This command allows the user to back-up the current game save without modifying it.
  • New command: restore. This command is functionally equivalent to 'restore', but was provided to
  • Backup now also writes a decrypted, formatted JSON file. This makes it easy to restore a backup by simply using the encrypt command with one of these JSON files as input.
  • Backup now includes the game mode in the output file name.
  • Backup now by default only makes a copy of the unencrypted JSON file rather than the full archive of the save dir. A full archive is still available with the --full-backup option. make the process of restoring a backed-up game-save more explicit/obvious to the end user.
  • Significant internal refactoring to separate the command-line interface from the save-game abstraction. This will allow that code to be used in other contexts (like a GUI).

Many thanks to the authors of the following software libraries used by nmssavetool:

I would also like to thank No Man's Sky mod maker 'nomansuniverse' and 'Mjjstral', who discovered how to decrypt the V1 format NMS save files.

You can’t perform that action at this time.
