Hi,
my goal is to create a Mouseover for a unit with information in it. I think 3d widgets are the way to go, but i’m struggling a little bit:
I have this in my class header:
//The Mouse over info
UPROPERTY(EditAnywhere, Category = Settings)
class UWidgetComponent* InfoDisplay;
And this inside the .cpp:
//Setup the widget:
InfoDisplay = ObjectInitializer.CreateDefaultSubobject<UWidgetComponent>(this, TEXT("InfoDisplay"));
InfoDisplay->AttachParent = RootComponent;
static ConstructorHelpers::FObjectFinder InfoDisplayObject(TEXT("Blueprint'/Game/HUD/Widgets/MouseOver/bp_MouseOverWidget.bp_MouseOverWidget'"));
if (InfoDisplayObject.Object)
{
InfoDisplay->SetWidgetClass((UClass*)InfoDisplayObject.Object->GeneratedClass);
}
If i compile this, everything is looking okay. I can see the widget in my blueprint. But as soon as i click “Compile” the editor crashes. After a restart, the “Info Display” widget is not visible anymore under the root-component. If I recompile, the widget appears again with the same setting as before the crash.
Does anyone know a work around, or am I doing something wrong?
This is the crashlog:
