UOperationSystem | Unreal Engine 5.8 Documentation

API > API/Plugins > API/Plugins/TedsOperations

System to execute externally customizable logic for a given purpose and input.

By deriving this type, an "OperationSystem" for a specific purpose may be created, to which customizable "Operations" can be registered. The system may then be invoked to "test" or "apply" a registered operation that fits the given input.
