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"

[Closed] StaticLoadObject doesn't work in a packaged game.

Hello all.

I want to create an Actor in C++, and this Actor is defined with Blueprint.

So, I tried this code below.

 UClass* Class = NULL;
 UObject* uobj = StaticLoadObject(UBlueprint::StaticClass(), NULL,TEXT("Blueprint'/Game/Project/Blueprints/TestCharacter.TestCharacter'"));
 if (uobj != NULL) {
     UBlueprint* blueprint = Cast(uobj);
     Class = blueprint->GeneratedClass;
 FTransform SpawnTransform;
 FActorSpawnParameters SpawnParameters;
 SpawnParameters.SpawnCollisionHandlingOverride = CollisionHandlingOverride;
 AActor* act = GetWorld()->SpawnActor(Class, &SpawnTransform, SpawnParameters);

It works fine when I run this in the UE4Editor.

But in a packaged game, StaticLoadObject() returns NULL.

In addition, I could create this Actor from Blueprint-to-C++ function like this in the same packaged game.

So, I think 'TestCharacter Actor' is cooked and included in a game package.

 AActor* AMyTest::SpawnActor(UClass* Class, FTransform SpawnTransform, ESpawnActorCollisionHandlingMethod CollisionHandlingOverride)

I'm using UE 4.10.1, and packaged for Windows 64bit.

Could you give me some advices?

Thanks in advance.

Hello Tatsuya-

Blueprints are defaulted to be stripped out when cooking. This can be overridden in the DefaultEditor.ini file by changing "bDontLoadBlueprintOutsideEditor" from true to false. After making this change and packaging again the result in the packaged version should match what is seen in the editor / standalone.
