Components and Extensions
The Combat System has multiple parts represented by interfaces. This design allows developers to replace parts of the system, by replacing components with their own functionality.
The only component that cannot be swapped by interface level is the Combat Component, since it is the backbone of the Combat System. Still, it provides many extension points as virtual/overridable functions.
The following table shows all components that can be swapped on interface level.
Interface | Implementation | Factory Method |

Providing Custom Components
Custom Components can be created by implementing the correct Interface, or extending the base class.
For cases where the base class is the default Combat Manager, you can implement the interface, only writing the logic for any function necessary, and for the others, you can retrieve the Combat Manager from the owner and call the original function.
Once your new components are ready, add them to your character and return them using the Combat System Interface. You only need to override functions that are relevant to your new components.
Conditional Component Creation
Another way to provide custom components, when some per-character logic is required, is to override the appropriate Factory Methods in the Combat Manager Component.
All appropriate Factory Methods are listed in the table above.
Movement Component
The Movement Component is a special case, since it overrides the Character Movement Component, therefore it is not created, or directly used by the Combat Manager Component.
You can replace the Movement Component using C++ or in your Blueprint.
