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"

UAIPerceptionComponent Implementation help

Hello, So I am starting to create my enemies and I saw this AIPerceptionComponent. Every time I try to implement this system on my AI controller I get Errors. This is the code I found:

 SetPerceptionComponent(ObjectInitializer.CreateDefaultSubobject<UAIPerceptionComponent>(this, TEXT("Sense")));

These are the errors:

  d:\program files\unrealengine-4.13\engine\source\runtime\coreuobject\public\uobject\UObjectGlobals.h(760): error C2027: use of undefined type 'UAIPerceptionComponent'

The compiler tries to tell you it has no idea what UAIPerceptionComponent is. You need to include its header, like so:

#include "Perception/AIPerceptionComponent.h"
