HI, I have extended a class from AIController and getting a lot of errors just from extending.
.h
#pragma once
#include "AIController.h"
#include "MyAIController.generated.h"
/**

UCLASS()
class AITEST_API AMyAIController : public AAIController
{
GENERATED_UCLASS_BODY()
};
.cpp
#include "AITest.h"
#include "MyAIController.h"
AMyAIController::AMyAIController(const class FPostConstructInitializeProperties& PCIP)
: Super(PCIP)
{
}
