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"

How to initialize and attach UActor Components in C++

Right now my code looks like this.

 // Header
 class UPawnSensingComponent* PawnSensor;
 
 // This compiles fine until I add the below in the CPP
 
 PawnSensor = CreateDefaultSubobject<UPawnSensingComponent>(TEXT("PawnSensor"));

It keeps giving me unresolved externals errors which makes me think there is some other step I am missing, but I can't for the life of me find it. At first I thought I needed to use SetupAttachment, but no such definition exists within the UPawnSensingComponent.

Does anyone know what I can do?

I guess that missing add dependency.

open [Project].Build.cs file, and search "AIModule" inside of PublicDependencyModuleNames (like, "Core", "Engine", "AIModule" ...), if "AIModule" not exists, add it. I hope it works.

Thanks. Also had to include the Perception/PawnSensingComponent.h, but it worked!
