Implementation

Blueprints

Check the Test Project for an in-engine example

Adding the interface

For an actor to have a faction, we need to add a FactionAgentInterface. This will allow the system to set and get the current interface.

To add an interface we have to go into Class Settings

From here we click on Add, inside Interfaces and search for FactionAgentInterface

Getting and Settings the Faction

Factions require your actor to define how to get and set a faction. That can be done overriding GetFaction and SetFaction.

A common implementation would be to have a variable (of type "Faction"), and then return it with GetFaction and set it with SetFaction:

Factions in Controllers

Sometimes you may want a controller to share a faction with its controlled pawn or character.

This process is exactly the same as before, except that instead of getting and setting a variable, we will get and set the faction from our pawn.
