FThreadedFunction

Overview

FThreadedFunction is a class derived from FRunnable, designed to simplify multithreading in Unreal Engine. It takes a lambda function as an argument and runs it on a separate thread, providing a straightforward way to perform background tasks without blocking the main game thread.

Properties

Type	Name	Access	Description
`TFunction<void()>`	Function	Private	The lambda function to be executed on a separate thread.
`TFunction<void()>`	StopCallback	Private	A callback function that is called when the thread stops.

Functions

Return Type	Signature	Description
`uint32`	`Run()`	Executes the lambda function and returns a success code.
`void`	`Stop()`	Calls the stop callback function to clean up resources before stopping the thread.

Usage & Implementation Notes

The class is designed for use in scenarios where background tasks need to be performed without blocking the main game thread.
The Run method executes the provided lambda function, and the Stop method ensures that any necessary cleanup is done before the thread stops.
This utility can be used in various parts of the application where multithreading is required for performance optimization or responsiveness.
