LimenGraphicSettingsLibrary

Overview

LimenGraphicSettingsLibrary is a utility class providing Blueprint callable functions for managing graphical settings such as resolution, window mode, and quality levels. It interacts with Unreal Engine's GameUserSettings to retrieve and set these settings.

Properties

Type	Name	Access	Description
FText	LevelTextRepresentation	BlueprintReadOnly	Represents the text representation of a quality level.
TEnumAsByte	Level	AllowPrivateAccess, BlueprintReadOnly	Enum representing the quality level.

Usage & Implementation Notes

This library interacts with Unreal Engine's GameUserSettings to manage graphical settings.
Functions are designed to be called from Blueprints for easy integration into game logic.
The implementation ensures thread safety and proper error handling through checks and assertions.
