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'

 D:\Program Files\UnrealEngine-4.13\Engine\Source\Runtime\AIModule\Classes\AIController.h(24): note: see declaration of 'UAIPerceptionComponent'

           with

         ]

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"
