Ambient Sea Traffic\
Ambient Sea Traffic brings the ocean around your island to life with neutral civilian and military vessels.
Ships automatically enter from a valid ocean edge, navigate across the map, and leave through the opposite side. They are purely ambient traffic: they do not belong to the player, do not occupy fleet capacity, and require no manual control.
\
Features\
\
- Automatic neutral sea traffic around the island\
- Civilian cargo vessels with multiple visual configurations\
- Three military ship variants\
- Individual ships and convoys of up to three vessels\
- Separate parallel routes for convoy members\
- Twelve-second delay between convoy vessels\
- Random entry point on a valid ocean edge\
- Destination on the opposite side of the map\
- Automatic route validation over the ocean\
- Uses the gameβs ship navigation and movement system\
- Maximum of six active or pending ambient vessels\
- No player ownership or fleet-capacity usage\
- No debug menu in the public version\
- Runs automatically without player interaction
\
Traffic frequency\
A new vessel or convoy is scheduled every **60β90 in-game days**, approximately every two to three in-game months.
Each traffic event contains between one and three vessels, depending on the current number of active and pending ships.
For every generated vessel:
\
- **35% probability:** military ship\
- **65% probability:** civilian cargo ship
The exact vessel configuration and valid ocean route are selected randomly.
\
How to use\
No manual setup is required.
Install and enable the mod, then load or start a game. Ambient traffic will begin appearing automatically after the first randomly scheduled interval.
The mod can be enabled or disabled through its configuration file:
```json
{
"enabled": true
}
Set enabled to false to prevent new ambient vessels from spawning.
Compatibility and saves
Ambient Sea Traffic is verified for Captain of Industry 0.8.6.
The mod can be added to an existing saved game and can also be removed safely.
Ambient vessels are temporary visual entities and are not stored as permanent player ships. Active and pending ambient traffic is safely removed before the game is saved, preventing temporary vessels from becoming part of save serialization.
After loading, the mod starts a new automatic traffic schedule.
Notes
- Ambient ships cannot be selected or controlled by the player.
- They cannot transport player cargo.
- They do not participate in contracts, trading, exploration, or combat.
- Their purpose is to add visual activity and atmosphere to the ocean.
- Traffic density is automatically limited to prevent unlimited vessel accumulation.
- A traffic event is skipped if the mod cannot find a safe ocean route between opposite map edges.
