Changelog

[1.1.0] - Check the bag - 2026-08-30

Dogs can now smell into backpacks, and the host decides every scent number.

Added

• Added backpack support, so a dog smells contraband inside a backpack mod's bag.
• Added a [containers] section to K9Scents.cfg for tuning how much smell escapes a bag.

Changed

• Moved every scent setting to the host in multiplayer.

Notes

• Editing K9Scents.cfg on someone else's game does nothing. That is intended.
• Backpack settings do nothing without a backpack mod, because the base game has no bag.
• K9Scents.cfg gains a [containers] section on first launch, keeping your tuned values.
• If halving the backpack number changes nothing, the sniff radius is already at its cap.
• Tested on both builds, single player and multiplayer.

[1.0.0] - Who let the dogs out? - 2026-08-29

First release. Police officers now patrol with a K9 dog.

Added

• Patrols:
  • Added officer-and-dog pairs to the game's own police foot-patrol routes.
  • Added a body search at the end of a pursuit, using the game's own search.
  • Added a search cooldown shared between every dog on the map.
  • Added a speed boost for a chasing officer, given back when the chase ends.
• Scent:
  • Added contraband detection, with the amount you are carrying deciding the range.
  • Added packaging muffling, so a baggie or brick leaks 60% of the smell and a jar 40%.
  • Added wall, floor and door muffling that cuts the range to about a third.
  • Added a ceiling of 1.5 times the sniff radius for very large stashes.
  • Added K9Scents.cfg, with an editable smell value per drug kind and container.
  • Added automatic scoring for drugs from other mods, by kind rather than by name.
  • Added an [items] section for overriding one exact item.
• The dog:
  • Added a dog that trots, sprints, sits, wags, sniffs and growls.
  • Added a teleport that recovers a dog stranded by stairs or a doorway.
  • Added a K9 harness skinned to the dog's own rig.
  • Added idle barks on patrol and an alert shout when a dog smells you.
  • Added a hittable, indestructible dog that raises the same assault crime as its handler.
  • Added a dog yelp that everyone in the lobby hears, not just whoever swung.
• Multiplayer:
  • Added multiplayer support, built on SteamNetworkLib.
  • Added client-side contraband reporting, sent only to the host.
  • Added host authority over spawning, pursuit and searches.
  • Added client-side dogs that follow the officers the game already syncs.
  • Added a host-or-yours split, marked on every setting in the config file.
  • Added a log line naming any player in the lobby without the mod.
• Builds and config:
  • Added 23 settings in K9Patrol.cfg, each explained in plain language in the file.
  • Added separate Mono and IL2CPP builds from one codebase.

Notes

• Everyone in the lobby needs K9 Patrol and SteamNetworkLib, matching their own build.
• Mixed Mono and IL2CPP lobbies are not supported.
• The config is read once at startup. Restart the game to pick up a change.
• Being chased, searched and coming up clean is intended, because the search respects packaging.
• Drugs added by other mods have not been tested.
• A second search straight after the first is a known issue with no cause found yet.
• Binds directly to the game's police, inventory and NPC code, so a game update can break it.
