Sea Spawn

Sea Spawn -

The folks over at Pirates of the Burning Sea have released details on their Open Sea Spawn Manager, giving insights into their spawn system.

In the end of my previous dev log I mentioned that there was work afoot to fix the issue of the incompatibility between the static spawn network in the nav zone with the port conquest system. This new system is now in place in the internal build of the game and being diligently tuned by the content department. The system that was created to fix this issue is called the "Open Sea Spawn Manager" and it has the following goals in mind:

  • Create semi-random shipping routes between ports
  • Eliminate empty pockets of NPCs in the nav zone
  • Create NPC ships of the appropriate level for their region
  • Ships spawned should be a function of port ownership
  • Ships spawned should be a function of port unrest
  • Allow owning nation of a port to lower the port's unrest
  • Allow nations attacking a port to raise the port's unrest


The open sea spawn manager is responsible for spawning and routing most of the ships in the open sea. The content department can still define custom spawns and patrol routes, but most of the original custom spawns will be removed. The spawn manager's job is to constantly try to make sure every port in the game has a set number of ships heading to it at any given time. Once a ship reaches its destination port it will sit outside the port for a set interval and then de-spawn. On a regular pulse, the spawn manager will find any ports that are below their desired spawn count and spawn another ship to head to the under-visited port. So for example, the spawn manager sees that Port Royal only has 3 ships heading toward it when it wants 5, so it spawns another ship at Jenny Bay and sends it on its way to Port Royal. Players destroying spawned ships bound for a destination port will also cause the spawn manager to create a new ship next update interval.
