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"

SetActorLabel before gameplay

I'm trying to set the actor label (the label in the scene hierarchy) in my OnConstruction() method, but doing so just crashes the engine. I can do it just fine in PostInitializeComponents(), but that renames it only when the game is being played. Here is the code for that:

 void AWorldItem::PostInitializeComponents()

How do I rename my actor from the default actor name, through C++, before the game starts?

Product Version: UE 4.12

Note that the label is for use only in Editor tools, not for shipping games (since ActorLabel is conditionally compiled based on #if WITH_EDITORONLY_DATA).

What are you trying to accomplish with the label? Maybe there is a better solution.

Mostly just for organizational purposes in the scene... I plan on having a bunch of these AWorldItem actors around, and it would be nice to look in the scene and see "Potion", "Sword", "Shield", etc.

I guess I could just use the names of the blueprint class that I place in the world. I'm just confused, why is this function in the engine if it just crashes?

Hmmm... I've never tried calling it from OnConstruction, but I could see how SetActorLabel could wreak havoc when renaming an actor. Maybe use PostActorCreated instead of OnConstruction. If this doesn't work, please post the stack trace of the crash.

You can always select the Actor in the World Outliner and rename it via the Details panel.
