FVector2D mousePosition = UWidgetLayoutLibrary::GetMousePositionOnViewport(GetWorld());

so that every tick to get mouse position... BUT!!! I get an error:

Maybe you have found the answer now, but this question has been bothering me for several days, so I decided to reply to you here, just add "UMG" in the specified position in Project.build.cs, maybe this question is too simple, there is almost no answer online.But for those who are just learning Unreal and C++, it is not known.

PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore","UMG" });
