Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

you might need to include an extra header file, because they separated a bunch of header files for faster compile times. maybe Object.h?

I believe any UObject or AActor should just be able to use that function, since its part of UObject.

Greetings - I'm working with version UE 4.18.1 and am encountering the same problem myself.

I tried including "Object.h" but to no avail. Does anyone know which header to include in order to get this working?

 #include "CoreMinimal.h"
 #include "GameFramework/Actor.h"
 #include "Object.h"
 #include "My_Actor.generated.h"
 
 UCLASS()
 class MYActorProject My_Actor : public AActor
 {
     GENERATED_BODY()
     
 public:    
     // Sets default values for this actor's properties
     My_Actor();
 ...
         // Visual Studio Can't find "PostEditChangeProperty"
     virtual void PostEditChangeProperty(struct FPropertyChangeEvent&) override;
 ...
 };

You missing the name in your Function. There are no special includes needed. Example Code:

 #pragma once
 #include "MyActor.generated.h"
 
 UCLASS()
 class AMyActor : public AActor
 {
     GENERATED_BODY()
 public:
 #if WITH_EDITOR
     virtual void PostEditChangeProperty(FPropertyChangedEvent& PropertyChangedEvent) override;
 #endif
 };
 
 //---- .cpp -----
 
 #include "MyActor.h"
 
 #if WITH_EDITOR
 void AMyActor::PostEditChangeProperty(FPropertyChangedEvent& PropertyChangedEvent)
 {
     Super::PostEditChangeProperty(PropertyChangedEvent);
 }
 #endif

Sorry for the slow response Nachtmahr. That seemed to do the trick. Thanks for pulling my head out of the sand!
