How do i get/set var from PropertyChangedEvent?

[Repin Design]

My code is crushing engine

#if WITH_EDITOR
void AUnitCharacteristics::PostEditChangeProperty(FPropertyChangedEvent& PropertyChangedEvent)
{
   FName PropertyName = (PropertyChangedEvent.Property != nullptr) ? PropertyChangedEvent.Property->GetFName() : NAME_None;

   // Attribute Base Value Has Been Changed
   if ((PropertyName == GET_MEMBER_NAME_CHECKED(FUnitAttribute, BaseValue)))
   {
      UFloatProperty* ChangedProperty = Cast<UFloatProperty>(PropertyChangedEvent.Property);
      float ChangedPropertyValue = ChangedProperty->GetPropertyValue_InContainer(ChangedProperty);

      if (ChangedPropertyValue < AttributeMinimalValue)
      {
         ChangedProperty->SetPropertyValue_InContainer(ChangedProperty, AttributeMinimalValue);
      }
      CalculateTotalAttributes();
   }
   Super::PostEditChangeProperty(PropertyChangedEvent);
}
#endif

You probably have an infinite loop due to this:

 
 ChangedProperty->SetPropertyValue_InContainer(ChangedProperty, AttributeMinimalValue);

Which is probably calling

   
 PostEditChangeProperty

again, which is calling SetProperty, which is calling postedit, which is

So you should not be setting property value in posteditchange


Have you tried using

virtual void PreEditChange(UProperty* PropertyThatWillChange) override;

instead?

Cause that seems like what you want, to modify the change before it occurs

should i use "this" as object reference when i set it up?

float ChangedPropertyValue = ChangedProperty->GetPropertyValue_InContainer(ChangedProperty);

If you crash may be because ChangedProperty is nullptr (cast failed).
